Chapter 30 Constant Temperature
"It's done?" Zhao Dong was at a loss when he heard the words, and immediately realized that a surprised smile appeared on his rough face: "It's really done?"

"It's really done!" Zhang Dingjun was also very excited: "The statistics just came out, the same is imported alloy steel, the gas consumption of our No. 3 annealing furnace is 1260 cubic meters, and the modified No. 5 annealing furnace only uses 945 cubic meters, a full 25% reduction in gas consumption.”

"25%... I'll be good, it's so much!" Zhao Dong was a little stunned.

"If it is actually applied, it will be more than this!" Zhang Dingjun disagrees.

"You mean the gas saving is more than 25%?"

"Of course!"

Zhang Dingjun said proudly: "Firstly, the coating we covered is relatively thin. Secondly, the coating did not cover the entire inner furnace wall, and only about 65% of it was completed.

The last and most important thing is that the No. 5 furnace has a long furnace life, the gap between the furnace door and the trolley, the furnace door and the furnace wall is relatively large, and the internal furnace gas overflows a lot during work. If these disadvantages are perfected , the energy saving can reach about 35%! "

"35%?" Now Zhao Dong was really shocked: "That's more than one-third, now our workshop doesn't have to worry about running out of fuel, haha..."

"Xiao Zhao, what did you just say? Why didn't I understand a word? What kind of energy saving is more than 25%, what can save one-third?"

Just when Zhao Dong was so happy that his back molars leaked out, Li Xin finally couldn't help it, and expressed the question in his heart suspiciously.

It wasn't just him, Zheng Yong, Huang Zhiguo and others also looked at Zhao Dong and Zhang Dingjun in a daze, and felt that the conversation between the two just now was like a scripture, and they couldn't understand it at all!

"It's such an old leader. Isn't our heat treatment workshop facing energy supply problems and unable to expand, delaying the 109 torpedo project in the factory.

The factory and the bureau were anxious about this, and our workshop itself was also very anxious, so we organized the cadres and workers in the workshop to brainstorm, offer suggestions, and then use the No. 5 furnace that we reported to be damaged to conduct experiments. Doctor Ma's stupid method, we did it unexpectedly..."

Zhao Dong, who was in a good mood, now had the confidence to speak, and immediately talked about the heat treatment workshop concentrating on energy-saving technology development.

In fact, it is almost the same, but the idea of ​​brainstorming was not thought up by Zhao Dong, but an idea given to him by his master Chen Jizu.

You know how there were so many engineers and technicians when the factory was built?
It's all these old masters sitting in the deserted open space, gnawing down the tricky things bit by bit.

Since the master craftsmen were able to solve problems together back then, why can't their heat treatment workshop not work now?
As the saying goes, three cobblers are as good as Zhuge Liang, and there are nearly a hundred heads in the heat treatment workshop. There may not be any professional technicians who are as good as they are, but they may be able to do it together. After all, they are front-line production personnel. My experience and skills are not something that can be learned in books.

So Zhao Dong called together the people in the workshop, asked everyone to give an opinion, and then screened out feasible ones for testing.

As for whether he can succeed, Zhao Dong has no idea to be honest, but doing it is better than waiting, at least he can go up and down the factory and see that their heat treatment workshop will never sit still!

In the end, it was really done by them!

After listening to Zhao Dong's words, Li Xin's eyes showed a little appreciation, but he didn't express his opinion immediately, but looked at Zheng Yong who was with him.

Zheng Yong shook his head noncommittally: "There are many ways to save energy. If you sacrifice the performance of the equipment and reduce the quality of the product... Such energy-saving applications are really putting the cart before the horse!"

Before he finished speaking, Zheng Yong looked at his student Huang Zhiguo: "If I remember correctly, your factory does not have a corresponding technical reserve for energy conservation!"

Huang Zhiguo nodded: "Not yet!"

"Then what principle are you using?" Zheng Yong looked up at Zhao Dong and Zhang Dingjun!
The meaning was obvious. They didn't believe that the heat treatment workshop could solve the so-called energy-saving technology alone. Not to mention Huang Zhiguo, even Wen Lin, who was in charge of accompanying him, couldn't refute it.

Because what Zheng Yong said is right, the Lidong Factory has never worked hard on energy conservation since the establishment of the factory. If this is the case, why did it suddenly have energy-saving technology?
It can also be applied to the annealing furnace that is reported to be damaged. What is it if it is not cutting corners and making nonsense?
You must know that seeking truth from facts is the standard for everything nowadays. This kind of deceitful deception that was popular more than ten years ago is very serious, so Wen Lin immediately winked at Zhao Dong with a serious expression. The meaning is obvious. If If it's a deceit, hurry up and find a step down, and he will help make things right.

Zhao Dong also felt a little guilty. After all, he came here early this morning to accompany the expert group to a meeting in the factory and to conduct a discussion of a guiding nature, so he was not watching at the scene at all.

Due to the previous failures, Zhao Dong is honestly not sure if this time it really reached such a heaven-defying level, what if it is an example that cannot be replicated.

"I have a stupid mouth, and I can't say one, two, three like intellectuals, but you will know if it works? Anyway, whether industrial production is good or bad, you can't fake it. I don't believe in the good things we make. It really can be criticized as worthless!"

However, just as Zhao Dong was due, Zhang Dingjun spoke suddenly, without giving Zheng Yong any face. Before he finished speaking, he put the whistle on his chest in his mouth, and three long whistles and one short whistle instantly resounded throughout the workshop .

At the same time, someone near the No. 5 furnace not far away raised a small flag, Zhang Dingjun also pulled out a small flag, and played a semaphore to start warming up with the sound of a whistle.

About half an hour later, the crane hoisted a batch of gear components for ship transmission. Li Xin narrowed his eyes when he saw this, and said, "This set of components weighs more than three tons..."

Then, he turned to Zhang Dingjun: "I remember that your No. 5 furnace is only rated at 2.8 tons. Can your No. 5 furnace hold such a large component?"

"I couldn't fit it before, but after the transformation, the rated capacity of furnace No. 5 has reached 3.8 tons, so this 3.75-ton gear set is not a problem at all!"

Zhang Dingjun responded with a smile.

Immediately, Li Xin's eyes became more fascinated: "You actually increased the rating of the furnace?"

"So your energy saving is calculated according to the average rating?" At this time, Zheng Yong squinted at Zhang Dingjun. There is no way. According to common sense, the greater the rating, the more energy is consumed, just like cooking. It is a truth that the more the amount of fire is used, the greater the amount of fire.

But it is another story to spread it evenly on every kilogram of material.

To put it bluntly, this is just a simple number game. Zheng Yong, who is engaged in economics, is a veteran in this field. Because of this, seeing that the rating of No. 5 furnace has increased by one ton, he feels that he has finally found the mystery of Zhang Dingjun's so-called energy saving.

So he didn't hesitate to name the tricky ones, but just as Zheng Yong said this, before he could increase his size, Zhang Dingjun looked at his watch and smiled: "The heating time of our No. 5 furnace is enough. Now, the temperature can be kept constant!"

"Is the temperature constant?" Now, before Zheng Yong could speak, Li Xin immediately lost his composure: "It's only been a little over an hour and your No. 5 furnace has been at constant temperature?"
