Although the conversation between the two workers was not loud, Liao Jingsheng, Li Heshan, Hu Ping and others stood beside him, so they naturally heard it all.

Looking at Li Heshan who opened his mouth wide beside him, Liao Jingsheng couldn't help but sigh: "Company Commander, I'm convinced you. You can find such a great college student to teach us anytime. Tsk tsk, it seems that I can't help but not invite this wine today!"

Although Li Heshan was confused, he certainly couldn't refuse when he heard that there was alcohol. He laughed and said, "Old Liao, you can do it if you know it's amazing! I..."

Before Li Heshan could finish his words, the quenching process had changed, and he swallowed everything he wanted to say.

Zhao Guoyang used a clamp to clamp the hot workpiece and carefully put it into the quenching liquid. Then he turned to Ning Xiaohong and said, "Secretary Ning, please adjust the temperature of the electric stove. Well, just adjust it to 625℃, and wait a while to use it!"

"Okay!" Ning Xiaohong's instructions to Zhao Guoyang were following the rules. Seeing that the workpiece had started to cool down, she quickly ran over and re-activated the temperature of the electric stove.

Anyone who knows it knows that the specific heat capacity of steel is very small, and at room temperature (25℃) is only about one-twelve of that of water.

In other words, the ratio of heat absorbed or released by the same mass of steel and water when changing the unit temperature is about 1:12, so the temperature change rate will naturally be much faster.

Now there is an addition of quenching liquid. The workpiece in Zhao Guoyang's hand has been quenched after only about a minute.

Zhao Guoyang carefully observed the changes on the surface of the workpiece. After seeing that it was almost done, he immediately clamped the workpiece out of the quenching liquid with a clamp, and immediately handed it over to Ning Xiaohong, who was also holding the clamp, waiting aside.

"Secretary Ning, the next step is to rekindle. This time may be a long time, so we will take turns." Zhao Guoyang said with a smile.

"No, I can do it alone!" Although Ning Xiaohong didn't know what "retreatment" Zhao Guoyang said, and how long it took to flip the workpiece to be clamped.

But at this moment, with so many people watching, how could she admit defeat?

Looking at the girl's stubborn appearance, Zhao Guoyang couldn't help but smile.

In fact, "retempering" is no more than quenching, it takes half an hour.

Although this workpiece is not heavy, it is still about ten pounds. It is still difficult to hold your hands in the air for such a long time.

However, Zhao Guoyang had almost understood the character of Section Chief Ning, so naturally he could not refute her immediately, so he could only let it go.

After waiting for about ten minutes, just when Ning Xiaohong's arms were sore and could not hold on, she held her arm with both hands.

"Secretary Ning, please help me prepare a clean platform and a high-power fan. Secondary quenching will require air cooling after a while." Zhao Guoyang said in an orderly manner.

Ning Xiaohong knew that Zhao Guoyang had found a step for him, and her pretty face turned slightly red, and nodded slightly and let her go aside.

Half an hour later, the "retreatment" process was finally completed.

Zhao Guoyang steadily clamped the workpiece and placed it on the clean table that Ning Xiaohong had prepared, and then signaled that she could turn on the fan.

Air cooling is slower than water cooling, but it is easier to save time.

After finishing all these tasks, Zhao Guoyang looked at the workpiece, nodded, and greeted Liao Jingsheng: "Okay, Director Liao, the construction has been completed!"

"Mr. Zhao, you are so awesome, so awesome!" Liao Jingsheng walked forward with a hint of excitement and held his hands tightly with both hands.

"Director Liao, you have been awarded the award. These are just some basic quenching methods." Zhao Guoyang said modestly.

"To be honest, I was still practicing in a large machinery factory in Lin Province for a long time during my college holiday, so I still have a good understanding of this aspect."

"It's true that he is a college student, both theoretical and practical, and he is a talent!" Liao Jingsheng said to Ning Xiaohong beside him while holding Zhao Guoyang's hand.

"Xiaohong, how about it? Are you convinced today?"

Although Ning Xiaohong had long been convinced, she didn't want to admit defeat so quickly.

She lowered her head and said softly, "Comrade Zhao... is very powerful, but it still depends on the actual effect of the workpiece. If it is really better than the original products of our factory, it will be...that will count!"

"You, you are still the unyielding temperament." Liao Jingsheng pointed at Ning Xiaohong with his finger and said with a smile.

In fact, the reason why he likes this disciple the most is because of her unyielding personality and willing to study it.

Otherwise, Xiangyang Machinery Factory is not an old high school student without higher education. Why should she train her a yellow-haired girl who graduated from a technical secondary school?

When Liao Jingsheng was "teaching a lesson" to his beloved disciples, Hu Ping and Li Heshan also stepped forward and pulled Zhao Guoyang to complain for a while.

"Xiao Zhao, you are not kind-hearted. You are obviously a college student, but you keep hiding it without saying anything. Why, are you afraid of scaring the old brother?" Hu Ping said with a smile on his face.

"Yes, Xiao Zhao, you are a real person who doesn't show off. We are all out of sight, and you almost let Lao Liao laugh! Hurry up and tell all your secrets!" Li Heshan said carelessly.

"Yes, yes, don't hide it!" Hu Ping also said from the side.

"Hey, I'm just an ordinary college student, there's no secrets!"

Zhao Guoyang waved his hand and said, muttering in his heart: Two brothers, I am also for your own good. If you really tell all your secrets, you two might be so scared that they can't speak.

At this moment, the two workers and masters who were chatting with the fans over there shouted.

"Mr. Zhao, Mr. Zhao, OK, the temperature has completely dropped!"

"Okay, I'll come here now!" Zhao Guoyang heard this, quickly got rid of Hu Ping and Li Heshan's entanglement and hurried over.

"Well, I'll go over and take a look!" Ning Xiaohong, who was talking to Liao Jingsheng, saw this, and left his factory manager and followed.

Putting on gloves and picking up the clamp to clamp the first workpiece he created after he was reborn, Zhao Guoyang couldn't help but shake his head secretly.

Although this workpiece is quenched, tempered and secondary quenched, it is still not perfect due to limited technology.

With Zhao Guoyang's high standards and strict requirements, this workpiece can only be considered barely qualified.

But in front of two experienced workers next to him, the workpiece was flawless.

A worker looked at the smooth surface of the workpiece with no spots and exclaimed, "It's amazing, it's so amazing, there's nothing spots!"
