Chapter 282 The Age of Great Oxygen Steelmaking!
The importance of blast furnaces is self-evident. This is the core of smelting pig iron. One is to supply steel to the downstream of metal smelting, and the other is to supply materials directly to the grenade production line of the Military Industry Bureau.

"Regarding the blast furnace, Chen Laizi has organized the Military Industry Bureau to build an experimental blast furnace with a daily output of 2 tons of pig iron, which can meet the production of grenades to a certain extent. "

"How's the status of these two weapons projects?"

"The 60-millimeter force project is progressing rapidly, which is due to the fact that the arsenal has the production materials and design drawings left by the former central Soviet area arsenal. Chen Laizi led the technical workers of the arsenal and Comrade Zhao Zhangcheng to improve it on the original basis. The cannon, the overall design has been completed, is about to enter the manufacturing stage."

"It is more difficult to make a formal rifle in China, and the design drawings have not yet been drawn. Not long ago, the technical personnel of the entire project had differences on the technical route. Some people believed that they could take the technical route of seamless steel pipe barrels and give up the barrel drilling process. , saving man-hours and costs, while others are firmly opposed to seamless steel pipes and insist on the barrel drilling route. Although the cost is higher, the quality and accuracy of the barrel can be guaranteed."

"Oh? Can't this seamless steel tube make a gun barrel?"

"Yes, no, it is our traditional perception to make gun barrels from seamless steel pipes, but in fact, it has great defects. The lifespan of gun barrels made of seamless steel pipes is very low. In the past, the Central Soviet Area Arsenal used seamless steel pipes. I have built a small batch of barrels, and there was no problem at first, but after only [-] rounds of bullets were fired, the phenomenon of rifling and blasting began to appear. Now this barrel manufacturing process has been abandoned around the world, and the barrel is selected. Drilling route."

The current era of making barrels is divided into two main routes:
First, seamless steel pipe + rifled marking has the advantages of saving man-hours and costs and improving manufacturing efficiency. The disadvantage is that the barrel life and strength are average.

Second, the barrel drilling + rifling engraving, the advantages are very significant, high precision, high strength, long life, the disadvantages are opposite to the advantages of seamless steel pipes, the process is cumbersome, the man-hours are more, and the cost is high.

No way, the efficiency of barrel drilling has always been a world-class problem in the field of machinery manufacturing. It requires both high precision and high efficiency. How can there be such a beautiful thing.

As for the seamless steel pipe, it seems very beautiful, but in fact there is a serious defect - it cannot withstand the high chamber pressure generated by the firing of the bullet for a long time. will be scrapped.

How high is the chamber pressure of the bullet fired?

300MP!

This is several times, or even ten times, that of shotguns, black powder shotguns, and low-pressure firearms.

"It's just that I'm ignorant. What's the decision of the lame man on this issue?"

"Gun barrel drilling, and this decision means that we must also overcome the problem of gun barrel drilling... In addition, the problem of lack of professional and technical personnel is still extremely serious. Chen Laizi asked me to transfer a few anti-college students the day before yesterday. I heard that I also asked the boss to transfer Comrade Zhao Zhangcheng to give suggestions to the 60-force project."

"Yes, and bribed me with a can of meat."

"Hahaha……"

The trio let out a hearty laugh and burst into laughter.

"Chen lame is smart and has a lot of ideas. It seems that he should be the head of the military industry bureau. There is no mistake. In order to solve the coke problem and other technical problems, this guy specially wrote a letter of help to Yu Hua."

"Speaking of Yu Hua, I have to say that being able to build a sulfuric acid tower, design a coke oven, and create the theory of asymmetric cryptography with Professor Hua Luogeng is truly worthy of the professor's evaluation of 'worth an army'."

"About Yu Hua, a comrade from the security department sent me an analysis report, which is to speculate that Mr. Zhang San may be Yu Hua. There are two reasons. First, Mr. Zhang San once reminded Lin Wan on paper at Peking No. [-] Middle School. , to write a set of wrong questions in mathematics, Yu Hua was studying in Beiping No. [-] Middle School; secondly, Mr. Zhang San has top code-breaking ability, which means that his mathematical level is very good, Yu Hua is in line with these two points, he founded Asymmetric Cryptography theory, very high level of mathematics."

As soon as these words came out, the atmosphere in the cave changed. Regarding Mr. Zhang San, this is one of the top secrets of the entire organization.

There are currently two judgments about Mr. Zhang San, one is that Mr. Zhang San uses a pseudonym, and the other is his real name.

However, after so long undercover investigation, the organization still failed to find Mr. Zhang San.

"What do you think about this speculation?" The voice became slightly serious.

Is it possible that Mr. Zhang San is Yu Hua?

This guess is unusual.

So far, there are a total of seven Mr. Zhang San's true identities, and with this speculation, a total of eight.

However, the first seven guesses are far less important than this.

"I am against it. From the information we have so far, Mr. Zhang San has been abroad. He is about 35 years old. He has given us deciphering red secret materials, mechanical drawings, and barefoot doctor's manuals, involving mathematics, cryptography, Machinery, medicine and many other fields, but Yu Hua has never been abroad so far, and his identity and age do not match, the possibility of Mr. Zhang San being Yu Hua is very low."

"What about the boss?"

"I also don't think that Mr. Zhang San is Yu Hua. Although the speculation is reasonable, it is full of loopholes. Unless there is strong evidence to prove it, we must rely on evidence, not speculation."

"My opinion is the same, this analysis report is temporarily sealed."

"Report, emergency call from the north!" Suddenly, a correspondent entered the cave, reported the situation, left a message, and turned to leave.

"Is it the news from Lugou Bridge?"

"No, it's more important news than Lugou Bridge..."

When the telegram passed to the boss, just one second later, a clear saliva swallowing sound came from the quiet cave.

"The total smelting time for a single time is 30 minutes. The daily output is 96 tons, and the annual output is 3.5 tons of steel... This, is this true? I feel like I'm dreaming." The boss's voice has begun to tremble.

silence.

Dead silence.

The oxygen top-blowing converter technology described in the message has given the ultimate shock. They have experienced countless dangers and strong winds and waves, and they are also lost in the face of the terrifying productivity behind this technology.

No one can remain calm in the face of oxygen top-blown converter technology.

No.

Since the outbreak of the third industrial revolution, the material basis for human civilization to develop on a large scale and rapidly build modern civilization comes from the steel smelted by oxygen top-blown converter technology.

In later generations, the annual output of hundreds of millions of tons of crude steel is sparse. However, in this era, even the annual output of tens of millions of tons of steel is terrifying, enough to make a country easily join the club of industrial powers.

As for the annual output of [-] million tons of steel, it is unthinkable.

This is the world constructed by science and technology in the era of big oxygen steelmaking.

PS: I've been busy with everything, I'm sorry, I've been busy with funerals these days, and I'm exhausted and exhausted.
