Chapter 21 Improving Equipment
(If anyone in the industry sees the following content, please lightly spray it. I searched for the technology of domestic steel rolling mills in the 60s for a day, but I found a lonely one, so I had to force it)

"This, this, and this, take them all for me!"

After entering the warehouse, Jiang Deming unceremoniously directed several workers who came with him and Zhang Wenfeng to help.

From the knowledge gained from the system, he knew that in a few years, several workers would rely on the original equipment of the factory to improve the hydraulic device of the rolling mill, not only rolling out extremely thin strip steel, but also in a certain place. In terms of performance, it even surpasses the advanced level of similar products in the world in the current era.

What is beef batch?That's it.

It sounds like a fantasy, but people at this time have indeed done a lot of things that are incredible in the eyes of foreign countries

Anyway, there was something wrong with the hydraulic device, so Jiang Deming thought about improving it while repairing it, so as to reach the performance a few years ahead of schedule.

It's fine if you don't have the ability. Since you have the ability, you must do your best and do your best for the country.

Of course, if Jiang Deming alone had to rely on Jiang Deming to complete this transformation, it would take years of the monkey to complete it, thanks to the fact that this is a rolling mill full of talents.

There are several eighth-level workers like Yi Zhonghai. If Jiang Deming seconded one or two, it will be no problem at all.

In addition, Jiang Deming's own hands-on ability is not bad. With the concerted efforts of everyone, he finally made all the parts needed for improvement before dark, and the next step is to install them for testing.

Originally, according to Zhang Wenfeng's idea, it was enough to repair the machine, but when he heard Jiang Deming said that the hydraulic device could be improved and the strip steel could be made thinner, he was moved, but he could not make decisions on his own, so he ran to report Director Yang, when Director Yang heard it, it was all broken anyway, and it was not too late, just do it.

"Comrade Jiang, why don't we go have a meal first and continue when we come back? I'll let the cafeteria prepare it." Zhang Wenfeng moved to Jiang Deming's side and suggested.

Since the morning, everyone has been busy here. At noon, they ate some steamed buns from the cafeteria, which were delivered by He Yuzhu himself. When he saw Jiang Deming was here, his expression was very surprised, but he also had a sense of humor Didn't say anything.

Jiang Deming raised his wrist and looked at the time. It is already past six o'clock. It will take a lot of time to come back after eating, so he shook his head and said, "Director Zhang, take the other comrades to eat , I want to finish this first."

Zhang Wenfeng looked at Jiang Deming helplessly when he heard the words, if you don't go, how can others go?

But looking at Jiang Deming's serious look, Zhang Wenfeng had no choice but to give up the idea of ​​continuing to persuade.

With Jiang Deming taking the lead, it is natural for others not to complain anymore. After all, a student child who just came out of school is so active. What else can they say? Besides, everyone in this era is still poor. There are not many people who can eat and drink enough every day.

In addition, in order to increase everyone's enthusiasm, Zhang Wenfeng proposed that after a while, the cafeteria would give everyone extra meals. In this way, the big guys were even more motivated.

The only complaint is probably the chef class. It was already the second half of the year, but now because of this, he has to stay, especially He Yuzhu. An excuse to ask for leave.

In this way, Jiang Deming and the people in the workshop were busy until after nine o'clock in the evening, and finally finished the improved hydraulic device.

Jiang Deming took off his oil-stained gloves, picked up a towel beside him and wiped off his sweat, and said to Director Zhang, "Director Zhang, please come and order a trial production. It has been checked several times just now, and it should be no problem."

It is not a big area for improvement, otherwise it would not be possible to complete it in such a short time. Of course Jiang Deming is very confident now.

Zhang Wenfeng was a little excited when he heard the words. If it can really do what Jiang Deming said, then their third rolling mill will surpass other brother factories and become the benchmark for the entire capital rolling mill.

And as the person in charge of this workshop, his name is absolutely indispensable in the credit book.

Zhang Wenfeng coughed twice, and when everyone looked over, he looked around and said, "Then let's get started!"

With an order, the comrade in charge of operating the equipment immediately turned on the start switch.

Buzzing, after the machine ran for a while, a narrow strip of steel was rolled out.

Cheers erupted in the workshop, and Jiang Deming and Zhang Wenfeng also showed smiles on their faces, but this only proved that the calender had been successfully repaired, not that Jiang Deming's improved process had also taken effect, and further tests had to be carried out.

Jiang Deming said to the operator: "Comrade, adjust the value to the limit."

The operator hesitated a bit, and suggested: "How about we take it one step at a time?"

Jiang Deming shook his head and said, "No, just do as I say."

The operator had no choice but to turn his head and look at Zhang Wenfeng. After seeing him nodding, he gritted his teeth and said that the strip data modulation had reached the limit, and then restarted the machine.

This time the movement of the calender was louder than before, and everyone in the workshop had their eyes fixed on the sheet exit, and even their breathing became smaller unconsciously.

One second, two seconds, three seconds...

Jiang Deming clenched his fists involuntarily when he saw the silvery luster appearing at the outlet.

After a complete steel strip is rolled out, the next step is annealing, after which it has to be lubricated synchronously with the rolling size, coated with anti-rust oil, leveled and cut to length, and the polishing is considered to be completely completed.

But Jiang Deming and the others don't need to wait until it's all completed. After the annealing is completed, someone will come forward to measure it.

After a while, the person in charge of the measurement turned his head and shouted to Zhang Wenfeng: "Director Zhang, the thickness has reached 1.6MM, which is 2.0MM thinner than our previous 0.4 and is very well-proportioned."

Zhang Wenfeng was so excited when he heard the words, his voice was trembling: "Really, really?"

The surveyor nodded vigorously and said, "I can guarantee it with my qualifications!"

Zhang Wenfeng did not speak, but went forward to inspect it himself, and then confirmed that the rolled steel strip had indeed become thinner. Advanced steel rolling technology is required, and strip steel is very critical in this.

After Zhang Wenfeng put down the measuring tool, he trotted to Jiang Deming and held his hand, without saying a word, just shook it vigorously, which proved that he was very excited.

The rest of the workers in the workshop also started to cheer, forgetting the fatigue and hunger of the day.

Although Jiang Deming felt that he just did what he should do, he still couldn't help being infected by everyone's emotions.

While eating in the cafeteria, Director Yang, who had already returned home, rushed back to the factory and accompanied Jiang Deming to have a meal, not sure whether it should be counted as dinner or supper.
