my scientific age

Chapter 278 This is not a test of the cadre's imagination!

This is a bold guess.

Looking at Comrade Professor's expression, Lin Wan froze for a moment, as if realizing something, and her words were a little surprised: "Could it be that... Professor Zhuang is going to join the organization under the influence of Yu Hua?"

"It shouldn't be possible to join directly, but at least it reaches the level of helping us. Otherwise, with Yu Hua's temperament, he will not expose himself at will, and he will not initiate this emergency meeting." Liu Wei's eyes were filled with thought, and he said slowly. : "If Professor Zhuang can help us, it will be a great help for the entire base."

Liu Wei is very familiar with the situation in the base area. After all, he is the highest person in charge of the Northern Ministry and has the right to know.

Today, the pre-war production in the base area, which has been going on for more than two months, has achieved remarkable results, which is much better than the initial poor and white situation in the base area.

But that's not enough to be proud of.

Because, there are still quite a few problems in the various fields covered by the whole pre-war production plan.

Metallurgy, military industry, electric power, mechanical processing, lack of talents, technology and equipment, want to achieve the two general goals of 'establishing a lower-level basic industry' and 'self-produced light weapons military industry' formulated in the pre-war mass production plan, There is still a very long distance.

Fortunately, with the coking technical information and weapons production suggestions given by Yu Hua not long ago, the problems in the metallurgical and military fields of the base area have been alleviated.

One is to establish the most basic coking system with the help of the coking technical data based on Yu Hua to solve the problem of coke required for blast furnace ironmaking.

Second, the Military Industry Bureau invited a group of senior generals in the army to discuss and study the weapon model suggestions given by Yu Hua, and finally established the rifle model as a medium-sized rifle, while the mortar model paid tribute to the classic, imitating the Brand 60mm mortar.

Rifle models and mortar models have goals, but when they enter the actual research and development stage, the technical situation faced by the Military Industry Bureau is far more complicated than imagined, resulting in very slow research and development progress.

In general, the development of large-scale production before the war has reached a bottleneck period, and more force support is urgently needed.

If Professor Zhuang is really here to help the base area as they analyzed, this is really great news.

After listening to Professor Zhuang's resume, Liu Weiguang knew that this Tsinghua professor, who he had never met before, was definitely a top scientist.

What the base area lacks most is this kind of talent.

"You're right." Lin Wan nodded in response.

Liu smiled: "What time is it?"

"It's 6:10." Lin Wan raised her right hand, looked at her watch, and responded.

"It should be almost time, let's meet at the door." Liu Wei heard that, feeling that it was almost time, and then extinguished the cigarette butt in his hand.

Welcome in person, this is the way of hospitality.

Lin Wan nodded, followed behind Liu Wei, left the room, and walked towards the door of Kelai Teahouse.

Soon, Liu Wei and Lin Wan came to the door of the teahouse and stood quietly.

"Buzz!" Not long after, accompanied by the sound of a car engine working, a Buick car stopped steadily in front of the teahouse. Through the window, you could see Yang Xiu in the co-pilot and Yu Huahe in the back. A man with an unfamiliar face.

Lin Wan quietly looked at Yu Hua, who had not seen him for a long time in the car, with a shallow smile on her face.

When the car stopped, Yang Xiu quickly got out of the car, went to the back seat to open the door, and stepped aside, showing respect for the two people in the back seat.

If Yu Hua's knowledge is already high enough to make him admire, then this professor Zhuang Qianding, who works at the National Tsinghua University, undoubtedly makes him only look up.

Professor of National Tsinghua University!
Yu Hua and Zhuang Qianding got off the bus on the right in an orderly manner and stood in front of the teahouse gate.

At this time, Liu Wei stepped forward steadily, with a refined smile on his face, and stretched out his right hand: "Student Yu, long time no see."

"Steward Liu, long time no see."

Yu Hua nodded to Liu Wei, stretched out his right hand and held it together, greeted politely, and then let go of it naturally.

After some simple greetings, Yu Hua turned to introduce Zhuang Qianding next to him: "Liu Guanjia, this is my tutor, Professor and Head of the Department of Mechanical Engineering of National Tsing Hua University - Zhuang Qianding."

"Hello, Professor Zhuang, my name is Liu Wei, I welcome you on behalf of the North, just call me Butler Liu." Liu Wei's eyes fell on Zhuang Qianding, he stuck out his right hand again, and said with a smile.

"Hello, Steward Liu, it's a pleasure to meet and meet you." Professor Zhuang was dressed in a very formal dress today, wearing a suit, showing the refined temperament of a top scholar, and shook hands with Liu Wei generously, nodding with a smile.

As for the red organization, he had only heard of it before, and he had never been so close.

"Hello, Professor, I'm Lin Wan, a university student at Peking University, and the head of the Northern Department of Science." Lin Wan stepped forward, bowed slightly, and greeted Professor Zhuang as a student.

"Hello, classmate Lin, I heard Yu Hua talk about you, you are very talented in the field of mechanical design." Zhuang Qianding looked at Lin Wan, nodded and said.

Before this meeting, Yu Hua had informed Liu Wei, Lin Wan and others about relevant information. Zhuang Qianding was quite curious about Lin Wan, firstly because of her female identity, and secondly because of Yu Hua's evaluation and top mechanical design talent.

"You're too good, professor, the students are just average." Lin Wan was stunned for a moment, then glanced at Yu Hua, a little embarrassed, and said modestly.

Zhuang Qianding smiled and said nothing.

"Professor Zhuang, classmate Yu, let's go first, this is not the place to talk." After a brief exchange between the two sides, Liu Wei made a sound at the right time, signaling everyone to enter the teahouse.

"Guests are as you wish, please, Steward Liu." Zhuang Qianding nodded and smiled.

A smile appeared on Liu Wei's face, and then he led the crowd into the gate and into the teahouse.

……

Inside the teahouse, in the previous meeting room, a pot of Longjing was placed on the table. The guards quietly left and closed the door.

Outside the conference room stood two guards, in charge of security.

Liu Wei stood on the seat, raised the teapot with his right hand, poured tea for Zhuang Qianding and Yu Hua, and then poured tea for Lin Wan and himself.

After pouring, drink tea.

Yu Hua picked up the teacup and took a sip of Longjing. Well, it's still a familiar taste, delicious.

The four of them drank tea, and Liu Wei took the lead in putting down the teacup and entering the topic.

"Student Yu, what is particularly important?" Liu Wei glanced at Professor Zhuang and asked.

"Steward Liu, Jin Yu, today's meeting is because of a technology that can change the fate of China." Yu Hua didn't talk nonsense, he went straight to the point, and stared at Liu Wei and Lin Wan in front of him, his voice solemn and solemn.

Technology enough to change the fate of China?
"Student Yu, what kind of technology is it?" Liu Wei was slightly surprised when he heard the words, his face changed, and his tone was somewhat puzzled and solemn.

Naturally, Yu Hua will not aimlessly. So, what exactly is this technology that can change the fate of China?
As soon as the voice came out, Liu Wei and Lin Wan's eyes were all focused on Yu Hua.

Yu Hua didn't answer this question, and turned his eyes to Zhuang Qianding beside him.

"Oxygen Top Blown Converter Technology."

Zhuang Qianding said solemnly, took out the design drawing of oxygen top-blown converter from his briefcase, placed it on the table, and handed it to Liu Wei: "This technology was created by Yu Hua, based on the principle of oxygen steelmaking, through oxygen lances The pure oxygen is fed into the steel-making converter to realize the high-efficiency steel-making process. At present, the time required for the first open-hearth steel-making furnace is about 7-12 hours, and the oxygen top-blowing converter steel-making time for the first furnace is about 25-40 minutes. In fact, the molten steel smelting reaction time is only about 15 minutes."

"15 minutes?!" As Professor Zhuang Qianding's voice fell, when Liu Wei was still in a state of ignorance, Lin Wan, who had a little understanding of iron and steel metallurgy, had widened her eyes and showed an extremely shocked expression.

"Yes, the smelting is completed in 15 minutes, and the rest of the time is spent on charging and tapping." Yu Hua said at this time, nodding in affirmation.

15 minutes of molten steel smelting reaction time.

25 minutes - 40 minutes total time interval.

Lin Wan carefully picked up the design drawing of the oxygen top blowing converter, and watched it carefully. At this moment, no words could describe the shock and incredibleness in her heart.

"Comrade Lin Wan, is there anything unusual or special about this 15-minute smelting time?" Looking at Lin Wan's reaction, and then feeling the solemnity of Yu Hua and Zhuang Qianding, Liu Wei, who is not familiar with the steel industry, felt in his heart Full of doubts, he tidied up his wording a bit and asked.

It looks like this technology is really amazing.

"Professor, this smelting time itself is extremely abnormal. Assuming that a 100-ton open hearth furnace takes 7 hours to smelt one furnace of steel, then only about three furnaces of molten steel can be smelted in 24 hours a day, regardless of the quality loss of steel slag and other substances, then The ideal total mass is equal to 300 tons."

After hearing Liu Wei's question, Lin Wan finally recovered from the shock, briefly rationalized her thoughts, and slowly explained: "Now, according to the calculation of the smelting time of this oxygen top-blown converter technology, it is assumed that it is also a 100-ton converter. , take 30 minutes to smelt one furnace, 24 furnaces can be smelted in 48 hours a day, what is 48 furnaces multiplied by 100 tons?”

"How much is 48 furnaces multiplied by 100 tons..." Liu Wei was stunned.

At this moment, he was really stunned.

The whole person's brain banged, and instantly fell into a blank, and a number echoed in the center of the mind - 4800 tons!
Substance: Steel!
Looking at Liu Wei's sluggish and inconceivable expression, Yu Hua and Lin Wan looked at each other, but did not remind them aloud. Only after the professor understands the concept of this data, can he truly understand the true value and value of oxygen top-blowing converter technology. importance.

It is no exaggeration to say that the oxygen top-blown converter technology can completely determine the national fortune and future of China in 1937.

Only by understanding its value and importance can it be adequately protected.

The whole of China can ensure that the oxygen top-blown converter does not fall into the hands of the Japanese, only the organization.

The meeting room was kept quiet, and the three of them remained silent, allowing Liu Wei to digest the shocking news.

"Professor Zhuang, classmate Yu, that is, the oxygen top-blown converter can make 4800 tons of steel per day, right?" After a few breaths, Liu Wei came back to his senses and was able to digest what Lin Wan explained. Information, raised his head, a pair of eyes revealed almost trembling excitement and excitement, looked at the two, and copied the terminology clearly and accurately.

Steel!

4800 tons of steel per day!
This is an astronomical number that Liu Wei could not imagine.

Calculated at 4800 tons of steel per day, as long as there is this oxygen top-blown converter, the annual output of steel in the base area will instantly increase to 170 million tons.

What is the concept of 170 million tons?
Liu Wei doesn't know, but he can compare that the annual output of steel in Nanjing is not more than [-] tons.

One is 170 million tons, the other is [-] tons...

At this moment, Liu Wei felt that he was going crazy. He finally understood why Lin Wan, who was usually very stable, would react like this.

Damn, this is not testing the imagination of cadres, but destroying the values ​​and cognition of cadres!
Liu Wei originally thought that the big event that he was going to talk about today was that Professor Zhuang was suspected of helping the organization, but he thought that Yu Hua would straighten this out for him and drop a blockbuster.

"Yes, but not entirely correct. If the steelmaking process is well controlled, the charging and tapping time can be shortened to about 30 minutes. In theory, the daily output of a 100T oxygen top-blown converter can indeed reach 4800 tons, but we are temporarily The 100T converter cannot be achieved, and the raw material supply system in northern Shaanxi cannot afford it.”

Zhuang Qianding shook his head. Out of scientific rigor, he pointed out that the requirement of producing 4800 tons of steel per day was to be met. He poured cold water on Liu Wei and replied in a straight voice, "This is a 2T-level test furnace designed by me and Yu Hua. , the total smelting time for a single time is about 30 minutes, the daily output of steel is 96 tons, and the annual output is 3.5 tons.”
