Siheyuan Great Craftsmen

Zhou Tian's mind instantly displayed the parameters of the P-type gun steel in his hand. He found that the tensile strength, yield strength, elongation, cross-sectional shrinkage, and impact energy data all seemed to be much worse than what he had originally designed.

“Recommended heat treatment schedule: Normalizing at 880°C with air cooling; Quenching at 870°C with oil cooling; Tempering at 560 - 650°C with air cooling.”

Soon after, an improved plan emerged.

"So that's it!" Zhou Tian couldn't help but nodded in his heart, then looked at Song Weiguo.

"There are indeed problems with the parameters of this piece of artillery steel. It should be that there are errors in several quenching processes. Next, I will write down several quenching procedures. You can give it to the production unit and ask them to try to produce it again according to this process!"

As he spoke, Zhou Tian pulled out a blank drawing, lowered his head and began writing on it, quickly writing down the processing steps that came to his mind.

Song Weiguo saw that Zhou Tian just picked up the gun steel and felt it, and he discovered the problem.

Although he also knew that Zhou Tian was the designer of the cannon steel, this was too unbelievable! He stared at Zhou Tian with wide eyes, unable to believe it, as he lowered his head to write the quenching process of the cannon steel. He was completely stunned.

He once thought that Zhou Tian was a genius, but the degree of this genius was too beyond his imagination. He was simply not in the same world as ordinary people like them.

"Okay, Brother Song, here you go!"

While he was still immersed in the extreme shock in his heart, Zhou Tian had already handed him the drawing full of content. Song Weiguo took the drawing with a dazed mind, looked down at the densely packed formulas on it, and felt a confusion in his mind, then looked up at Zhou Tian.

"Hey, Director, isn't your efficiency too fast?"

"What? Can't you hurry up?"

Zhou Tian naturally understood that his performance just now was a bit too much. But now time is running out, the battlefield on the peninsula will end in more than a year, and now that the military is backing him up, he did not intend to deliberately hide his strangeness from Song Weiguo.

In the future, he will have to continuously produce various industrial equipment and machinery. If he conceals them, how can he quickly improve the domestic industry?

The most important thing is that the two of them will have to work together for a long time in the future. As long as they don't expose the existence of the space and the virtual space in their minds, it won't matter even if they behave a little bit evil.

It can also leave a general impression on Song Weiguo so as not to arouse his suspicion in the future.

Song Weiguo took the blueprint and nodded in agreement. Although he was still shocked by Zhou Tian's performance, as Zhou Tian said, it was indeed a good thing to hurry up.

"But the problem is, this is not just a little bit fast!"

Song Weiguo complained silently in his heart, and did not think about it any more. After all, before he came here, he had read Zhou Tian's investigation report and knew that this kid had an amazing learning speed, which could be called a demon. He was relieved a little, picked up the drawings and put them in his bag, stood up, put on his coat, and said with a wry smile:

"I just came back and haven't had time to have a cup of hot tea yet. I have to start working again. Director, you are really something."

Although he was complaining, his body was still honest and he picked up his bag and hurriedly left the office.

"Who told you to stay in the same office with me? You'll suffer in the future!"

Zhou Tian watched Song Weiguo's departing back, shook his head and smiled, muttering to himself.

After all, as he lets go, there will definitely be more and more research results in the future. It would be a good thing to let Song Weiguo get used to it as soon as possible.

But Song Weiguo left the office and went to the Security Department first. He took a platoon of soldiers to escort the drawings and drove towards the Shijingshan Iron and Steel Plant.

The car soon arrived at the Shijingshan Iron and Steel Plant. After Song Weiguo showed his ID, half an hour later, he met An Chaojun, the chief engineer of the Shijingshan Iron and Steel Plant, in front of a steel furnace. He had met him once more than ten days ago.

"Xiao Song, why are you back? Is Master Zhou not satisfied with the performance of the gun steel? But that is already the result of our best efforts!" An Chaojun looked at Song Weiguo walking hurriedly towards him, then walked up to him and said.

"No, Engineer An, Director Zhou discovered that there were several errors in the production process of your artillery steel, so he asked me to send it over so that you can start production again!"

Song Weiguo didn't waste any time and went straight to the point. He took out the drawings that Zhou Tian handed to him from his bag and handed them to An Chaojun.

"The process is wrong?" An Chaojun was stunned when he heard this, and a trace of displeasure flashed across his face. However, he did not say much, but silently took the drawing from Song Weiguo's hand and looked down to check it.

When he saw the several processes on the drawing, his expression was obviously stunned, and his initial displeasure turned into astonishment, then to surprise, and finally to shock.

"Well, I didn't expect that the cannon steel could be hardened like this, and the air return, yes, it should be like this, yes, it can be like this!"

As he spoke, An Chaojun murmured in a low voice as if no one was around. He closed his eyes only after he finished reading the contents on the drawing, and kept recalling the quenching steps on the drawing in his mind.

A minute later, he immediately opened his eyes and shouted loudly: "Lao Gu, Lao Gu, come quickly!"

"Director, what's the matter?"

As An Chaojun shouted loudly, an old man in work clothes hurried over.

"Old Gu, you must immediately arrange for someone to follow the steps above to produce a new batch of cannon steel for me. Remember, there cannot be any mistakes in the steps here. Arrange it immediately!"

An Chaojun did not look at Song Weiguo, but spoke loudly to the workshop director Gu Chaojun.

"Yes, factory director!"

Upon hearing this, Gu Chaojun glanced at An Chaojun who was excited, then looked at Song Weiguo beside him, nodded, took the drawings and went to make arrangements.

Soon, as the iron ore was transported to the workshop, the steelmaking furnace began to emit a blazing fire. The blazing heat seemed to make people feel like they were in the hot summer. However, in the eyes of An Chaojun and Song Weiguo, it could not stop them from looking forward to refining artillery steel.

In 1951, since most of my country's iron and steel mills used open-hearth steelmaking, the steelmaking efficiency was not high, and it took a whole day and night to produce a furnace of blasting steel.

After the workers quenched the steel according to Zhou Tian's drawings, the originally dark steel turned out to be even darker.

"Is this done?"

An Chaojun and Song Weiguo looked at the cannon steel in front of them. They had not slept for a whole day and night, and now their eyes were glowing red as they asked anxiously.

"Quick, quickly arrange for someone to test it!"

"Yes, factory director!"

Gu Chaojun, who had been waiting beside the two of them, responded, picked up a piece of gun steel with pliers, and arranged for people to start testing.

Not long after, Gu Chaojun ran in happily with a piece of test data.

"Director, Director, the test report is out. It's in compliance with the data on the drawings sent by the steel mill!"

"Really? Bring it here, let me see it!"

An Chaojun took a step forward, snatched the data report from Gu Chaojun's hand, and without caring about the soreness in his eyes, he lowered his head to look at it.

The more he read, the more excited he became. Finally, when he finished reading the report, he laughed happily.

"Hahaha, we succeeded, we finally succeeded, we have our own artillery steel, and we can also produce artillery!"

As An Chaojun laughed, Song Weiguo stepped forward and took the data from An Chaojun's hand and looked down. When he saw that the data above were close to the data in the Zhoutian drawing, he couldn't help but show surprise on his face and clasped his hands together.

"It really worked! That's great! It's really great! No, this matter must be kept secret!"

After the surprise, he suddenly remembered the impact and significance of the successful research on artillery steel and immediately calmed down.

He looked at An Chaojun, who was smiling happily, with a serious expression and said, "Engineer An, the matter of the artillery steel must be kept confidential. It cannot be disclosed to anyone for the time being. I will immediately ask the old leader for his opinion!"
