my scientific age

Chapter 208 Y-beam!

The nickel-manganese material in the glass bottle weighs about 1937 grams. Obviously, in the era of [-], this metal, which was very common in later generations, was expensive, and the outer packaging used glass bottles.

After waiting for so long, I finally got the two key materials that were urgently needed.

For Yu Hua, the nickel-manganese metal, which is highly controlled by the Nationalist government, has absolutely no access and channels. Of course, if he wants to, he can go to Tianjin City to find Zhang Zizhong, but Yu Hua does not want to contact Zhang Zizhong too much.

Respectful, but not close.

"Thanks, how much?" Yu Hua took the two glass bottles, thanked Lin Wan, and asked.

"I don't need money, it was given to you by the organization." Lin Wan shook her head. Although nickel and manganese are expensive, the amount Yu Hua wants is extremely rare, adding up to only five yuan.

Of course, if the two materials are converted into price per ton, it is ridiculously expensive.

50 grams of nickel, 3 oceans, equivalent to [-] oceans per ton.

50 grams of manganese, 2 oceans, equivalent to [-] oceans per ton.

What is expensive?

This is!
The reason why nickel-manganese materials are so expensive is mainly due to the high foreign demand, coupled with the lack of nickel resource exploration and mining capabilities in China, more than [-]% of the country's nickel-manganese ore is mined by foreign companies for export, earning foreign exchange, resulting in the price of Stay high.

Of course, the National Government has no plans to change this. Not only is it not prepared to change, but it is even willing to see such a situation, because the higher the domestic nickel and manganese price, the higher the tax.

If you can't use it yourself, you don't need mining costs, and you can collect huge taxes on exports. Why not do it?

"Thank you to those comrades for me, Jin Yu, this is what I just wrote. Please give it to Mr. Wu along with this technical information and technology transfer contract."

Hearing this, Yu Hua nodded and did not continue to struggle. He put the two glass bottles on the table, opened the drawer, took out two documents, and then compiled the articles just written on the table, handed it to Lin Wan, and smiled. : "I have signed the technology transfer contract. When Mr. Wu signs it, Yu's Seven Pagoda Technology belongs to the organization, and the technical information is very important. As for the third article, it is my technical suggestion for the establishment of the sulfuric acid industry in the base area. Regarding technical difficulties I have written all my questions and questions on it, so I can avoid detours.”

"it is good!"

When Lin Wan heard this, her face immediately became serious, she immediately understood the importance of these three-point documents, she solemnly took the three documents with both hands, and was about to turn to leave, when she suddenly realized something, turned around, looked at Yu Hua, and was silent for a second, Asked: "Ready to go?"

"Well, it's almost time. I'm going to leave early tomorrow. I will trouble you with the remaining work. You know, learning is my pursuit." Yu Hua smiled, did not reject the question, nodded affirmatively.

It is late May, and the end of the month is approaching. Yu's Seven Pagoda R&D project ends one day ahead of schedule. Yu Hua is ready to return to Peiping to prepare for the upcoming life in Tsinghua Garden.

Entering Tsinghua Garden in June, the Lugou Bridge Incident broke out on July [-]th, and around August, the exams for students studying in the United States on public funds will be held in Nanjing, and the time is very tight.

Hearing this, Lin Wan fell silent again, staring at Yu Hua with eyes like jewels. After three seconds, she nodded earnestly: "I will try my best to catch up with you, see you in Tsinghua Garden, Yu Hua."

There is no reluctance, no sadness, no little daughter's gesture, everything seems free and natural.

"See you at Tsinghua Garden, Jinyu." Yu Hua smiled.

The bedroom door was closed and silence returned.

After Lin Wan left, Yu Hua turned to look at the two glass bottles on the table: "It's better to hit the sun if you choose another day, and take advantage of the transformation of a miniature electric furnace tonight to make armored steel samples, and this smelting technology, also It can provide an effective means of metal smelting for the organization, after all, the Red Army has no shortage of oil and coal."

Electric melting furnace, also known as electric arc furnace, uses the high temperature generated by electrode arc to smelt metal. The melting temperature is as high as [-] degrees Celsius. It can basically meet the smelting needs of all materials. It can smelt high-quality alloy steel and high-strength steel, as well as gold and silver. , copper, aluminum, manganese, nickel and other metals, effectively remove various impurity elements, improve purity and material performance.

Its working principle is very simple. It only needs to put an energized electrode into a crucible containing metal material, and then smelting can be carried out.

The disadvantage is that electricity must be used, and the energy consumption is huge.

This is one of the mainstream metallurgical processes in later generations. Its working principle is almost the same as that of electroslag remelting technology. It is essentially based on the physical principle of thermal effect of electric current, and its status and status are lower than that of electroslag remelting.

Of course, the electric arc furnace and electroslag remelting seem to be the same, but in fact there is a big difference. In terms of the material properties of the final smelted metal, the former is equivalent to an unguided rocket, and the latter is equivalent to a precision-guided strategic ballistic missile.

Generally speaking, the steel produced by the electric arc furnace also needs to be purified by electroslag remelting in order to meet the needs of the gun barrel and the gun barrel.

The status of electroslag remelting cannot be shaken.

Well, what's interesting is that the requirements of this 'barrel' and 'barrel' are the military weapons and equipment standards of prosperous China. The performance requirements of high-strength steel in the current era are not as harsh and abnormal as those of later generations. The high-strength steel can meet the strength requirements of the barrel and the barrel.

And this, for the base that does not lack oil, the electric arc furnace metallurgical process based on electric energy is simply great news.

You must know that in history, the manufacturing of weapons and equipment of the Eighth Route Army has always been trapped in the backward level of metallurgical technology. Due to the inability to independently manufacture high-strength steel and high-quality alloy steel, the steel for the production of grenades, gun barrels and bullets basically comes from the Japanese theater. Rail Resources.

The Eighth Route Army has no shortage of strategic materials such as gasoline and diesel!

"Electric arc furnace technology, even if it's a gift from me to the organization..." Yu Hua whispered softly.

Do what you say, no ambiguity.

The generator, submerged arc welding machine and steel are all ready-made. The crucible only needs a graphite electrode and a graphite container. The preconditions for the entire smelting process have been fully lit, and there is no obstacle.

Yu Hua does not need various tall electric arc steelmaking furnaces with a single furnace capacity of 100T in later generations. He only needs a small electric arc furnace with a single furnace capacity of 2 kg to meet the demand.

Picking up the glass bottle containing the nickel-manganese material, Yu Hua left the bedroom and walked towards the brick house No. [-] where the submerged arc welding machine was placed.

……

Making a crucible is essentially a game of mud.

The whole graphite crucible is composed of a graphite inner wall, a refractory material and a stone outer wall. The graphite is sourced from the previously purchased materials, the refractory clay is the loess and gravel in the corner, and the stone outer wall is the pounding pot contributed by Xiong Shenggang.

At three o'clock in the morning, on the vacant land of the first brick building, a simple stove was built. The temperature in the stove was as high as [-] degrees Celsius. .

Burn at high temperature for an hour and a half, the time is up.

Holding the tongs, Yu Hua carefully took out the graphite container and the graphite rod that had just been fired one by one. The surface of the graphite container was reddish, revealing a hard feeling, and when he touched it lightly, there was a sound similar to metal.

The graphite container made of natural graphite is the crucible with the highest thermal conductivity. When cast iron crucibles and steel crucibles are still widely used in this era, the thermal conductivity of graphite crucibles is a dimensionality reduction blow.

After the graphite container had cooled down a little, Yu Hua put it into a tamping jar.

"Sir, the yellow mud and gravel you want." Xiong Shenggang, who was on the side, showed respect, and brought dry yellow soil and gravel.

There were only two people in the yard, Xiong Shenggang and Yu Hua. After the previous celebration, he returned to the No. [-] brick and tile building to be on duty and guard the equipment. After Yu Hua arrived, he began to help.

Yu Hua nodded, then put the refractory clay into the gap between the tamping pot and the graphite container, and then poured all kinds of irregular scraps: "Ready to start."

everything's ready.

Hearing these words, Xiong Shenggang turned on the submerged arc welding machine that had been connected to the electricity according to the pre-arrangement, adjusted to the maximum output power, the welding tongs clamped the graphite rod used as an electrode, and after doing all this, he reported: "Sir, I Ready."

"Xiong Shenggang, before proceeding to the next step, I want to ask you, are you absolutely loyal to the organization?" Yu Hua did not rush to the next step, staring at Xiong Shenggang in front of him, and asked in a serious voice.

loyalty!

This is the most basic and important thing. It was defined by Yu Hua as the electric arc furnace technology for the meeting ceremony. Although it was born as early as the early 1937th century, it is undeniable that this technology was still an advanced metallurgical technology in the era of [-]. Process technology, especially graphite crucibles.

Graphite crucibles and electric arc furnaces are a perfect match. Although Yu Hua does not know what type of crucibles are used in electric arc furnaces in the iron and steel metallurgy industry around the world, graphite crucibles are definitely not used.

Because this is the crucible technology developed in modern times.

The importance of loyalty lies in whether this technology will be leaked. Xiong Shenggang, who has a junior high school education, is undoubtedly the best candidate for learning and using this metallurgical technology.

After getting along and observing for this period of time, Xiong Shenggang has a calm personality, good conduct, strong observation and execution skills, and most importantly, his strong body did not affect his brain.

This man is very smart.

"Yes!" Xiong Sheng was stunned when he heard this question, his face was a little red, his back was straight, and he responded loudly without thinking.

For soldiers, especially for a soldier, Yu Hua's question is tantamount to...

humiliation.

But Yu Hua's extremely solemn expression made Xiong Shenggang not dare to get angry. He had never seen Yu Hua show such an expression before.

"Okay, I hope you won't let me down, Xiong Shenggang, this is the technical data of the new electric arc furnace smelting process invented by me, which can smelt high-strength pistol barrels, rifle barrels, mortars and recoilless guns. Steel, and other high-quality alloy steels, this technical information includes the technical principle of electric arc furnace, graphite rod formula, graphite crucible formula and firing requirements, which are the most important core secrets of electric arc furnace smelting technology, as long as the single furnace capacity reaches 6 kg, which can meet the needs of 60mm caliber mortar barrels.”

Yu Hua looked at Xiong Shenggang, and took out the technical documents of the electric arc furnace written overnight with his right hand. His eyes were bright, revealing an inexplicable momentum. : "And your task is to learn and fully master this metallurgical technology, understand?"

The formula of graphite rod and graphite crucible is the soul of electric arc furnace metallurgy. The formula of graphite crucible given by Yu Hua has a performance level of around 2010, which is completely sufficient.

"What?" Xiong Shenggang felt as if his mind was hit by a heavy hammer, and his heart shook, he couldn't believe he heard it.

High-strength steel for making pistol barrels, rifle barrels, mortar barrels, and recoilless guns, as well as other high-quality alloy steels, can be smelted!

Although Xiong Shenggang only had a junior high school education, he couldn't bear it. He was eager to learn and was willing to take the initiative to understand and learn unfamiliar knowledge. It happened that he knew some basic knowledge about metallurgy.

The metallurgical level determines the quality and performance of steel. Due to the lack of sufficient metallurgical technology, the current metallurgical level of the base area is still in the state of 'iron-making' and cannot make steel.

Iron is easy to make, but steel is difficult to make.

High-strength steel for gun barrels and gun barrels is almost a dream.

Who doesn't know the benefits of self-made weapons and equipment, but how can rifles and cannons be made without good steel?

However, what did he hear now?
Mr. Yu Hua in front of him has invented a new type of electric arc furnace process, which can smelt high-strength steel and various high-quality alloy steels.

He, Xiong Shenggang, a junior high school graduate, understands the concept and weight of 'high-strength steel' and 'high-quality alloy steel'!
"Xiong Shenggang, your mission is to learn and fully master this metallurgical technology, understand?" Yu Hua did not explain in detail, but asked again seriously.

Xiong Sheng just heard the meaning of Yu Hua's words, agitated, and quickly stood in a military posture: "Understood!"

Yu Hua nodded, took a step forward, and handed the notebook containing the technical data of the metallurgical process of the electric arc furnace to Xiong Shenggang, and instructed: "About this technology, after I leave, you will tell Mr. Wu, just say It was a surprise for him, a gift to the organization."

This meeting ceremony, Yu Hua is going to make some surprises.

"Yes." Xiong Shenggang was shocked and moved, is this the world of genius?
A metallurgical technology with extremely high value is just a 'meeting gift'?
You know, this is an important technology that has been lacking for a long time in the organization team, and it is completely strategic.

Xiong Shenggang hurriedly took the notebook and protected it like a peerless treasure. He suddenly realized something and looked at Yu Hua: "Sir, are you leaving?"

"Let's go at dawn, give me the welding tongs." Yu Hua nodded and replied.

Xiong Shenggang, who showed reluctance in his eyes, took the welding tongs in his hands. Yu Hua put on protective sunglasses, then pressed the switch, holding the welding tongs with both hands, and controlled the graphite rod connected to the current into the graphite crucible.

"Zi..." A dazzling and hot electric arc emerged, and the scrap steel in the graphite container turned red and melted at a speed visible to the naked eye, and the temperature rose exponentially, easily breaking through a thousand degrees Celsius and reaching the melting point.

All the steel melts rapidly, gradually forming red molten steel in liquid state, releasing rolling heat.

Watching this scene, Xiong Shenggang, who was standing next to him, was extremely shocked and swallowed his throat involuntarily. The raw material heated up and melted so quickly, which was completely unimaginable for him who often smelted iron. A real and profound knowledge.

After the molten steel in the graphite crucible was fully reacted, the purity and strength were improved, and Yu Hua did not continue to heat it to avoid the molten steel temperature being too high.

Adjust the power of the submerged arc welding machine to medium to maintain the current temperature, the welding tongs are controlled by Xiong Shenggang, and then take out a glass bottle, take out [-] grams of manganese metal, and put it in molten steel.

The role of manganese is to improve the strength and hardness of steel. After fifty grams of metal manganese enters the high-temperature molten steel, it melts rapidly. Yu Hua waits for the steel and manganese to fully react before adding nickel.

Nickel can improve the flexibility and corrosion resistance of steel. Under the action of nickel and manganese, the anti-tipping performance and strength of the entire steel plate will be qualitatively improved compared with the most advanced tank armor steel in various countries.

Anti-dipping performance and strength increased by a full 10%!

If the Germans adopt the most advanced cold forging process, the anti-tilt performance of the new armor steel will be improved.

The smelting process continues.

Yu Hua, who has done thousands of simulations in his mind by approximating the physical system by thinking, is extremely skilled, no worse than those front-line workers. Coupled with the super-high computing speed of the thinking computer, the accuracy can reach the millisecond level, and the success rate up to 99%.

After 5 minutes, a furnace of perfect molten steel was released, poured into a mold and cast into shape.

A sample of armor steel that should have been born in the 70s was born in [-].

"Let's call you Y-shaped steel, take the initials of my name in pinyin, I hope you can shine abroad." Yu Hua looked at the fiery red steel plate in the mold that met the expectations, a smile appeared on the corner of his mouth, and there was hope in his eyes.

Xiong Shenggang next to him was paying close attention to the electric arc furnace and the graphite rod. He did not notice the difference in the molten steel in the furnace. Of course, he could not see any difference. Most of his attention was on the electric arc furnace and the graphite rod.

The internal structure of the Y-section steel is in a recrystallized state, and there is no difference in appearance from other steel plates.

……

Early the next morning, at dawn.

At the entrance of Liucun Village, elegant men, Liu Wei, Lin Wan and other members of the design team were standing, and in front was Yu Hua who had packed his luggage.

There is no practice banquet, no grand farewell scene and team, quiet when you come and quiet when you leave.

"Comrade Yu Hua, see you next time, study is a big event, I wish you further and further and become a world-renowned scientist." The elegant man had a gentle and kind smile on his face, and sent his blessings to Yu Hua.

"Mr. Wu, Hua Ding lived up to your expectations." Yu Hua nodded and said goodbye.

"That's good, let's go, pay attention to safety on the road." The elegant man smiled.

"Jin Yu, Xiao Yu, Old Zhou, I'm leaving." Yu Hua turned to the three people standing on the right, passing Lin Wan, Fang Yu, and Zhou Yuan's faces, speaking solemnly.

"It's not parting from life or death, pay attention to safety, see you in Tsinghua Garden." Lin Wan showed a natural and generous smile, like a lotus flower, waving goodbye.

"Yu Hua, see you at the Sipailou campus." Fang Yu's mouth curled slightly, and the smile was neither shallow nor light, like an orchid.

Sipailou Campus, the site of National Central University, is located in the center of Nanjing.

"Old Yu, if you have a chance, see you in Tsinghua Garden. If you don't have a chance, I will invite you to eat at Jiaotong University next time." As for where to eat, Zhou Yuan, who was not ranked in the top [-] in the city in the joint entrance examination, seemed very free and easy. Tsinghua Garden also OK, Jiaotong University will do.

"Okay, bye everyone."

Yu Hua nodded with a smile, looked around the crowd, and saluted.

After the ceremony, turned around and got into the Buick.

"Om!" Buick slowly moved forward, and under the watchful eyes of everyone, it slowly left Liucun along the road.

Yu Hua left, leaving a gift to meet him. As a comrade, he set foot on the road to Tsinghua Garden with everyone's expectations.

Basic science determines the upper limit of applied science, and academic level determines the upper limit of scientific research ability. Yu Hua needs to improve his academic level again.

The core goals of the next stage - oxygen top-blown converter technology, electroslag remelting technology.

"My future and hope in China are all tied to a talented student like Yu Hua. You must do a good job of Yu Hua's safety." The elegant man stood on the spot, looking at the Buick car that was gradually moving away, and sighed softly.

Liu Wei heard this and nodded.

At this time, Yang Xiu suddenly ran over and greeted the elegant man. Not far away, Xiong Shenggang appeared on the main road of Liu Village.

……

In the evening, the red clouds filled the sky.

At the northern foot of Qilian Mountain, south of Yumen, Laojun Temple.

Laojun Temple is located in a valley, backed by a cliff and facing the Shiyou River. Under the erosion of wind and sand all year round, the surrounding wall of Laojun Temple has collapsed. Weeds and gravel are everywhere in the temple, and there is no scent of incense.

The whole area is deserted, only a few hunters live more than ten miles away.

Today, Laojun Temple, which has been uninhabited for a long time, welcomed a group of guests.

More than [-] people walked along the bumpy path. More than a dozen horses marched smoothly with exploration tools and supplies. At the forefront of the team was the guide Tao Hu, who passed through the woods in front of the Laojun Temple. The whole team was stable. Stopping in front of the temple gate, this is an oil exploration team composed of soldiers and technicians, affiliated to the northern Shaanxi base.

"Comrade, here we are, this is the Laojun Temple you're looking for." Tao Hu, with his face covered in weather and sunburn, stood at the front of the line, looked at the Laojun Temple, took a few breaths, and moved towards Liang Daya behind him. said.

"Thank you, my fellow. After more than 2000 miles, I finally arrived..." Liang Daya, the military chief of the oil exploration team, thanked Tao Hu gratefully. Tao Hu is a local hunter and a serious local. It will take more time and energy for the guide to lead the team to find the Laojun Temple located in the deep mountains and old forests.

The Laojun Temple, built during the Tongzhi period, was gradually forgotten due to its remote location and sparsely populated areas.

Tao Hu quickly shook his head: "Thank you, just a little busy."

Liang Daya smiled, looked at the tattered Laojun Temple, and finally breathed a sigh of relief. He had some expectations in his heart, and gave orders in an orderly manner: "Xiao Li, Xiao Zhu, you are responsible for vigilance."

Starting from Yancheng, leaving the base area, passing through the three provinces of Shaanxi, Gansu and Ningxia, trekking across mountains and rivers to Yumen in the Hexi Corridor, the entire oil exploration team finally arrived at Laojun Temple. The journey was about 500 miles and took 20 days.

I have to say that this was a long and arduous journey. I encountered many dangers along the way. There were bandits, wolves, and local soldiers and bandits. Rao, Liang Daya, the company commander of the first cavalry reconnaissance company of the Red Army, was tired. Enough.

Fortunately, the team arrived at their destination without a hitch.

"Yes!"

The two young warriors in the team immediately shouted.

"Huzi, take your communication team up the mountain, set up a radio station, and send a report to the headquarters. We have arrived at Laojun Temple, and we will start the exploration work immediately." Liang Daya looked at Li Hu, the leader of the communication team in the team, and said road.

"Yes!" Li Hu, the communications squad leader, stood at attention, raised his right hand in a military salute, and immediately led the three communications squad up the mountain.

After issuing a series of orders, Liang Daya looked at the oil prospectors in the team: "Comrade Yan Shuang, I will trouble you next."

"I have read Mr. Xie Jiarong's "Gansu Yumen Petroleum Report". Zigan also said before that the geological conditions in the Yumen area are very good. There should be a large oil and gas reservoir with rich reserves underground, which has a very high industrial exploitation value. All the way, it's true."

Yan Shuang looked around the geographical situation around Laojun Temple and sighed: "From the geographical point of view, Laojun Temple is located at the northern foot of Qilian Mountains, which belongs to the piedmont fold belt of Qilian Mountains geologically. The geological structure is complex and it is an asymmetric dome back. Inclined, mostly sandstone-based…”

Yan Shuang, geological expert, petroleum engineering expert, graduated from the Department of Mining and Metallurgy of Peking University with a bachelor's degree, and obtained a master's degree in petroleum engineering from Norman University in the United States. He is the director and person in charge of oil exploration in Yanchang.

The Laojunmiao oil exploration mission was led by Yan Shuang.

Looking at Mr. Yan Shuang who was eloquent about his professional knowledge, Liang Daya had to nod his head again and again, but he was a little helpless in his heart.

After studying hard for so long, his understanding of geology and geological exploration is still at the initial stage, and there is basically no progress.

There is no way, it's not that he doesn't want to learn, but these things...

too esoteric.

It's just embarrassing his big teeth!
Following Mr. Yan Shuang all the way, Liang Daya understood one thing, people are really different.

Professional matters can only be handled by professionals.

For this task, he Liang Daya firstly found Laojun Temple and drew a road map, and secondly, protected Yan Shuang and other oil exploration personnel, and Yan Shuang was responsible for other professional tasks such as oil exploration.

The team entered the Laojun Temple and stationed on the spot. It was late, and the exploration work was carried out tomorrow. The soldiers and accompanying technicians unloaded equipment and materials and buried pots to make rice.

"Report, the headquarters is calling." After the team was settled properly, a correspondent ran down from the top of the mountain, entered the temple, and reported to Liang Daya.

Liang Daya took the confidential message and looked at it.

Liang, Petroleum Exploration Team Electric:
The situation has been known. Your team acted according to the plan and must protect the safety of technical personnel. The second batch of drilling and exploration equipment and food supplies have arrived in Xi'an and are expected to arrive at Laojun Temple on June [-].

Chen May 24

"Return to the headquarters, my team has received it, and we will start drilling and exploration work tomorrow. Please rest assured that oil will be found."

"Yes!" The correspondent turned and left, ready to call back.

Liang Daya turned around and walked out of the Laojun Temple, standing at the door, looking towards the open space 15 meters away due north, with a fiery gleam in his eyes.

oil!

oil!

oil!

Oil must be found!
