Siheyuan Back to the 1950s

After Sun Zhengguo finished dealing with the affairs of the Ministry of Metallurgy, he was always thinking about the technical transformation work in the factory.

So he rode his bicycle and rushed to the Red Star Steel Rolling Mill.

When he arrived at the warehouse, he saw Chen Lianshan and Zhao Guoping, together with a group of technicians and workers, busy working.

"Hey! Deputy Section Chief Sun is back."

A sharp-eyed worker was the first to notice Sun Zhengguo and immediately shouted loudly.

When the others heard the voice, they stopped what they were doing and greeted Sun Zhengguo enthusiastically.

"Hello, Deputy Section Chief Sun."

"Hello everyone, go about your business! Leave me alone."

Sun Zhengguo responded to everyone with a smile, signaling them to continue working.

After saying hello, Chen Lianshan and Zhao Guoping, the two temporary persons in charge, hurried over to report the work progress to Sun Zhengguo.

"Deputy Section Chief Sun, we have successfully repaired a machine today. As for the other parts, we will follow your requirements completely. We will leave all the parts we don't understand and wait for you to come back and guide us!"

Sun Zhengguo has great trust in his senior brother Chen Lianshan, knowing that he is serious and responsible in his work and has strong execution ability.

After Chen Lianshan finished his report, Sun Zhengguo asked about Zhao Guoping again.

"Guoping, how are the parts we need for the renovation work being prepared?"

"Deputy Section Chief Sun, the last piece was also processed this morning. I have measured it myself and it completely meets the requirements of the drawing. I am just waiting for you to come back and take charge of the overall situation."

Upon hearing such good news, Sun Zhengguo was overjoyed and immediately announced it.

"Okay, starting tomorrow, we will put aside the repair work and officially start the transformation of the hot rolling mill."

"okay!"

Zhao Guoping answered happily.

Since returning from the field investigation, everything seems to have become so good. His enemy, Section Chief Huang, was arrested, and he himself was promoted and got a raise.

Moreover, Sun Zhengguo revealed to him that the higher-ups were planning to promote a deputy section chief again and asked him to perform well. The meaning was self-evident.

Seeing that everyone was full of energy, Sun Zhengguo also changed into his work clothes and began to solve the difficult problems that remained.

Busy times always pass quickly, and half a month has passed in a flash.

During this period of time, the team led by Sun Zhengguo has been busy.

Although the hot rolling mill had been replaced with new parts, various problems continued to occur, and in the end, the machine could not even start normally.

Faced with such a dilemma, Director Yang was also very anxious.

He saw that Sun Zhengguo and others seemed to be "not doing their job properly". Not only did they stop repairing the broken machines, but they also devoted all their efforts to modifying the machines.

Director Yang couldn't help but want to speak up and remind them several times, but in the end he chose to remain silent.

The reason is simple. Sun Zhengguo is not an employee of the Ministry of Metallurgy. If he is angered, he may leave directly, and it will be too late to regret then.

In fact, Sun Zhengguo knew clearly that if he just carried out the renovation according to the drawings, he would inevitably encounter many problems.

After all, this drawing is just a theory, the real key lies in practical operation.

Fortunately, he has solid professional knowledge and can fully cope with these difficulties by relying on the experience and knowledge of past and present lives.

No matter when and where a problem arises, he can always find a solution quickly and handle it properly.

Today, after recalculating industrial parameters, many parts have been reprocessed and reinstalled, awaiting final testing.

"Reporting to Deputy Section Chief Sun, the roller device is normal and can be started at any time."

"Reporting to Deputy Section Chief Sun, the replaced parts have been inspected and are in good condition."

"Reporting to Deputy Section Chief Sun, the transmission device is normal and the line has been connected."

"Reporting to Deputy Section Chief Sun, the heating furnace is operating normally..."

"..."

With one report after another, the hot rolling mill, which had undergone many modifications, once again entered the critical process - trial start-up.

He had failed three times in this process. Even though he was very confident this time, Sun Zhengguo's palms were slightly sweating.

"Guoping, go and invite the factory leaders over! The test run will definitely require the presence of the leaders."

"I'll go right away."

After receiving the task, Zhao Guoping ran to Director Yang's office.

A few minutes later, Director Yang came running over with a group of cadres.

"Sun... Deputy Section Chief Sun,... how are the preparations this time?"

Director Yang asked expectantly, not caring about catching his breath.

Although he has been hit several times, Director Yang still hopes to succeed.

"Director Yang, there are too many changes this time. Many of the previous settings have been rejected. I can't guarantee it 100%."

Sun Zhengguo didn't dare to make too many promises. This is how scientific research works. Even a single step off will do.

Having said this, Director Yang had nothing to say and could only nod to show his understanding.

As the cadres entered, Sun Zhengguo arranged for his cousin to connect the main power supply.

Seeing his cousin nodding to him, Sun Zhengguo made a serious expression and announced with a wave of his hand.

"Turn it on."

"Buzz buzz...!"

Since it is a trial start-up, the heating furnace has not been officially started. The buzzing sound is made by the delivery device.

Seeing that the delivery device started normally, everyone just smiled and did not cheer, because the key to the hot rolling mill lies in rolling.

“Continue to the next step.”

Following Sun Zhengguo's order, Chen Lianshan pressed the second button without hesitation.

"Buzz buzz...!"

With the sound, the rollers began to rotate, faster and faster, and finally stabilized.

"Shift!"

With a command, the roller rotation began to accelerate, completely in line with the predetermined target.

"yeah……!"

“It worked…”

When everyone saw that the rollers had stabilized their rotation, they began to celebrate enthusiastically.

Because the most critical part of a hot rolling mill is the rolling device, which is now operating successfully, and the remaining transmission, cooling and unloading are no longer a problem.

However, in order to ensure the smooth operation of the machine, Sun Zhengguo still ordered the opening of the following devices.

The result is self-evident. The latter device is not too important and no changes were made at all, so there was no problem at all and everything started perfectly.

Although others were celebrating, Sun Zhengguo remained calm.

Just because it can be fully started does not mean that the transformation is successful. We must wait until the official production and obtain all the data for comparison before we can determine whether the transformation is successful.

After the machine had been running for an hour, Sun Zhengguo ordered it to stop.

After the machine stopped, seeing that Director Yang and several of his staff were still happily talking, Sun Zhengguo decided to cool them down.

"Director Yang, we don't need to be happy too soon. Let's transport the machine to the workshop today. We will have to conduct production tests tomorrow. Only when we get the real data can we determine whether this transformation is successful."

Sun Zhengguo's cold water poured down on Director Yang, leaving him chilled to the bone.

However, Director Yang was not discouraged. Even though it had failed to run several times before, this time it was at least half successful.

"Don't worry, Deputy Section Chief Sun, I will arrange for someone to dismantle the machine right away. I believe that this time, the transformation will be successful."

Director Yang said firmly.
