The train driver in the courtyard

The next morning.

The old lady got up before five o'clock.

She secretly lit the coal stove and cooked two poached eggs for Yi Zhonghai.

This was Yi Zhonghai's specific request.

In the words of Yi Zhonghai, two poached eggs skewered together with chopsticks would score 100 points.

As long as I eat "100 points", I will definitely get 100 points in today's promotion test.

An auntie thought that Yi Zhonghai was just craving for eggs.

Yi Zhonghai's family has not been having a good time recently.

For the sake of these two eggs, Auntie had to follow He Yushui and Liang Ladi to pick up coal cores next to the railway tracks.

However, if Yi Zhonghai can be promoted to an eighth-level worker, his salary can increase by more than ten yuan, which is worth it.

After watching Yi Zhonghai eat the fried eggs, the aunt cooked four bowls of cornmeal porridge.

One bowl was served to the deaf old lady, and the other three bowls were placed on the table.

At half past six in the morning, Jia Dongxu staggered in from outside.

He was not afraid of getting burned and huffed and puffed while holding the enamel bowl.

In a short while, the bowl of cornmeal porridge was finished.

Jia Dongxu even stuck out his tongue and licked all the residue on the porridge bowl clean.

Then he burped, rubbed his stomach and said, "Master, shall we go to work?"

Recently, Jia Dongxu always came to Yi Zhonghai's house early under the pretext of going to work, and he always managed to have a full meal.

Yi Zhonghai was also full at this time. He wiped his mouth with a towel and took the canvas bag from the old lady.

"Let's go. When I come back today, I will be an eighth-level worker!"

Yi Zhonghai led Jia Dongxu out of the house in a proud and confident manner, greeting the residents warmly along the way.

When he walked to the middle courtyard, he met Xu Damao and Li Aiguo who were walking out talking and laughing. His brows immediately frowned.

These two people are hanging out together, aren't they trying to do him harm?
"Da Mao, why are you working with Aiguo?" Yi Zhonghai couldn't help but ask.

"Do you live by the sea?" Xu Damao turned his head and asked with a smile.

These words confused Yi Zhonghai.

"Where does the sea come from in our capital?"

"Then why do you care so much?"

Xu Damao threw down a sentence.

Then, he sat on the back of the bicycle and slapped the seat hard. "Patriotic brother, can you take me with you?"

Li Aiguo's eyes widened: "I'll take you?"

"I got hurt yesterday while going to the countryside. Hehe."

"."

Li Aiguo always felt that Xu Damao was so enthusiastic today, he must have some ideas.

I didn't expect you were waiting here.

Well, just take it with you. You have to go to the steel mill anyway.

Looking at the backs of the two men, Yi Zhonghai was so angry that his teeth were chattering.

Jia Dongxu curled his lips and said, "Master, let's not bother with them for now. When you become an eighth-level worker, you can deal with them properly."

These words really touched Yi Zhonghai's heart.

Level 8 workers had a very high status in those days, and their position in the factory was comparable to that of factory leaders.

"Let's go, Dongxu, let's go!" Yi Zhonghai calmed himself down and ran towards the steel mill.

In the morning light, a burly young man rode a bicycle through the streets of the capital.

Seeing the young man, passers-by subconsciously looked towards the back seat, wanting to see the girl behind.

As a result, I saw a man with a donkey face.

What's so interesting about two grown men riding on a bicycle? It's boring, boring.

At this time, the bicycle passed the pothole and a man with a donkey face sitting on the back seat groaned rapidly and painfully.

"Ouch, ouch, hiss" He covered his butt with one hand and grabbed the young man's clothes with the other hand, his face full of painful yet refreshing expressions.

Passersby suddenly stopped and stared.

"That's quite a lot of fun. It's definitely much more interesting than a man and a woman riding a bicycle."

Li Aiguo stopped and pushed Xu Damao down.

"What's wrong?!"

Xu Damao covered his buttocks and said aggrievedly: "Yesterday I went to the countryside to show a movie. I went to the woods to relieve myself and got bitten on the buttocks by a rat snake."

Li Aiguo: "."

It seems that showing movies in the countryside is also a dangerous job.

Considering that Xu Damao was a wounded soldier, Li Aiguo forgave him this time.

Just wanting to sit on the back of a bicycle again is impossible.

Li Aiguo patted the smooth black front bar of the bicycle and said, "Come on, hang your legs over it, with your butt facing outwards."

Xu Damao: "."

Passers-by on the street: “⊙.⊙”

When Li Aiguo arrived at the steel rolling mill, Deputy Director Li and Section Chief Zhou were already waiting in the office.

After a few pleasantries, Section Chief Zhou raised his wrist to check the time: "Director, Driver Li, the promotion exam for fitters is about to begin. Should we go to the exam room?"

"Let's go." Deputy Director Li took the information that Li Aiguo handed to him, unbuttoned his coat, walked out of the door, and walked out with a vigorous look.

The examination room for the fitter promotion examination is located in the fitter workshop.

Because today is the exam for promotion from level 7 to level 8, which is the highest level exam in the entire steel rolling mill.

Fitter is the most important job in a steel rolling mill.

In order to allow the workers to appreciate the style of the master chefs, the workshop stopped production for two hours and the workers gathered in the workshop to watch the excitement.

Not only were there people from the fitter workshop, but also welders, blacksmiths, and even the canteen cook Nan Yi and helper Liu Lan were all there.

At this time in the workshop, Deputy Director Chen and several examiners had already started the preparations before the exam.

Yi Zhonghai took advantage of others not paying attention and whispered to Jia Dongxu: "Apprentice, today's test of the master is about precision boring in hole processing technology, and the lathe No. 2 is used.

When you prepare to bore the rod later, remember to use the hydraulic pump to remove the iron filings from the boring rod used by the master yesterday."

Hearing this, Jia Dongxu almost shouted out in surprise.

Precision boring is the simplest item in the benchwork assessment. As long as the dimensional accuracy is IT8~IT7 and the surface roughness Ra value is 1.6~0.8μm, it is considered qualified.

The most important thing is that Yi Zhonghai’s main job on weekdays is precision boring.

And lathe No. 2 is the best boring machine in the workshop.

The boring bar that Yi Zhonghai used yesterday was a Russian product. It had just been brought back from the logistics department. After a day of running-in, it was able to achieve the highest precision.

Using such a boring machine and the best boring bar, it was easy for Yi Zhonghai to pass the assessment.

The key is, how did Yi Zhonghai do it?
You should know that both the assessment items and the equipment used in the assessment are randomly assigned by the on-site examiners.

Looking at the factory leaders who were assigning practical projects to the seventh-level workers, Jia Dongxu lowered his voice and asked, "Master. You..."

"This is the master's ability! Don't talk too much, remember the task the master gave you."

Jia Dongxu still had some doubts.

But there were too many people, so he didn't dare to ask more questions.

Now it is Yi Zhonghai's turn to do this.

He walked forward and placed his credentials on the examiner's desk.

"Fitter workshop, seventh-level fitter Yi Zhonghai is here to report!"

Deputy Director Chen looked up at Yi Zhonghai, casually took out a piece of paper from the drawer, opened it and read: "The assessment item is precision boring, using lathe No. 2. Okay, Master Yi, go and prepare it."

"Thank you!" Yi Zhonghai took the note from Deputy Director Chen with both hands and looked at Jia Dongxu with a little excitement.

Jia Dongxu secretly gave Yi Zhonghai a thumbs up: "Master, you are really capable!"

Yi Zhonghai raised his head proudly.

Xu Damao hid in the crowd with his butt covered. When he saw this scene, he thought something was wrong.

This time, old man Yi Zhonghai is going to be promoted to an eighth-level worker.

But he had no way out.

After all, the eighth-level worker examination is the most important examination in the steel rolling mill. Not to mention a small projectionist like him, even the head of the publicity department cannot get involved.

"You're going to be unlucky in the future."

Liu Haizhong, who was standing next to him, clenched his fists excitedly.

If Yi Zhonghai becomes an eighth-level worker, he will have more advantages in dealing with Li Aiguo in the future.

Just then, there was a noise outside.

"Make way, everyone, make way."

As soon as Li Aiguo walked to the door, he saw Liu Haizhong standing in front of him with a big belly.

Liu Haizhong also saw Li Aiguo and immediately started to murmur, "Today is Lao Yi's exam day, why is Li Aiguo here?

Could it be that Lao Yi wants to... Impossible, this is an examination for eighth-level workers. Even if Li Aiguo is very capable, he cannot affect the examination."

His mumbling wasted time.

Deputy Factory Manager Li's face suddenly darkened: "Which workshop are you from? Don't you have any sense?"

Liu Haizhong was not afraid of Li Aiguo, but he did not dare to disrespect Deputy Director Li. He immediately twisted his fat body and squeezed into the crowd.

He happened to bump into Xu Damao.

"Liu Haizhong, go slower, you hurt my butt." Xu Damao covered his butt and sucked in pain.

Bangs: "."

Li Aiguo: "."

Deputy Director Li: "."

1024 employees on site: "."

Amidst many surprised, confused, puzzled and contemptuous looks, Liu Haizhong raised his hands and said: "Comrades, it's not what you think. I don't have that kind of hobby."

It didn't matter if he didn't explain, this explanation immediately caused a burst of laughter.

When Deputy Factory Director Chen heard the noise, he immediately stood up and said loudly: "This is an important examination area, silence!"

When he saw Deputy Director Li, Li Aiguo and Section Chief Zhou coming in, he frowned slightly and immediately went to greet them with a smile.

"Comrade Huaide, you are the deputy leader of the examination team. I was just about to send someone to invite you."

His words seemed like a greeting, but in fact he was warning Deputy Director Li that he was just a deputy team leader and should not cause trouble.

But at this time, Deputy Director Li had already obtained the Imperial Sword.

"Mr. Chen, how far has the exam progressed?" "We have just randomly selected practical projects for each candidate to ensure fairness." Deputy Director Chen was a little confused.

Deputy Director Li puffed out his chest and said, "All practical projects have been scrapped and replaced with 6-meter shearing machines."

As soon as these words came out, Deputy Director Chen's face turned ugly: "Li Huaide, as the deputy team leader, you do not have the power to change the practical project. Are you planning to disrupt the order of the exam?"

"I don't have the authority to do that, but Director Yang does."

Deputy Director Li took the materials from Section Chief Zhou and handed them to Deputy Director Chen: "At present, our steel rolling mill has undertaken an important project of Qianmen Locomotive Depot and needs a group of excellent fitters.

The 6-meter shearing machine itself is an assessment item, why can’t it be changed? "

Looking at Director Yang's signature on the materials, Deputy Director Chen's face turned pale.

If it were in the past, he might have given in, but he had promised an old friend.
Deputy Director Chen smiled awkwardly: “Comrade Huaide, the practical projects have been assigned now, and it would be inappropriate to change them.

Otherwise, after the fitter exam is over, I will organize these senior fitters to conduct a 6-meter shearing machine exam to select outstanding workers and masters.”

Deputy Director Chen’s idea does make sense.

But he forgot one thing, Li Aiguo really didn't care, after all, he just wanted the best fitter.

Read more latest popular novels at 6.9*shuba!

But Deputy Director Li came here for him, the team leader.

Deputy Director Li seemed to see something from Deputy Director Chen's panicked look, and said with a straight face: "Old Chen, you are the one who handled all the practical projects for the senior masters this time. You refused to change, is there something fishy going on?"

"What nonsense are you talking about, Li Huaide? I'm also a deputy factory director, and my ranking is higher than yours. Please show some respect!" Deputy Factory Director Chen was furious.

"I'm not against people, I'm against things!" Deputy Director Li looked around and said to the workers, "The 6-meter shearing machine is the most important equipment in our fitter workshop. Operating the shearing machine to process metal plates is a must-learn skill for every fitter.

Now someone is blocking the use of the shearing machine for the assessment, what the heck is going on?!"

It must be said that Deputy Director Li’s subsequent success was inseparable from his ability to mobilize the masses.

The workers nodded in agreement.

"The main job of fitters in our steel rolling mill is to cut plates, so cutting plates should indeed be included in the assessment."

"Sheet cutting looks simple, and an apprentice can do it, but if you want to do it well, you still have to learn from the eighth-level masters."

"I think Deputy Director Li's request is reasonable. If we conduct another assessment, it will definitely delay production."

There were even a few level 7 fitters who were taking the assessment who stepped forward on their own initiative.

“As the saying goes, it takes three years to make a good lathe operator, but ten years to make a bad fitter.

Shearing is the most challenging task for fitters, and it is the most challenging task for fitters’ basic skills. We require the use of shearing machines for assessment.”

Now that Deputy Director Li has the endorsement of Director Yang and the support of the workers, he immediately becomes more powerful.

Although Deputy Factory Director Chen realized that the situation was not good, he had no choice but to nod and agree: "Change all practical projects to shearing machines!"

When Yi Zhonghai heard this decision, his head was buzzing.

He had already made sufficient preparations, so how could things change?
"Is this kid Li Aiguo targeting me?" Yi Zhonghai gritted his teeth but did not dare to raise any objections.

On the contrary, in order not to arouse suspicion from others, he had to raise his hand to support the decision.

Yi Zhonghai felt very depressed.

Xu Damao's eyes widened with excitement: Can the Patriotic Brothers also get involved in the eighth-level promotion examination?
"Hiss, this kid is getting more and more powerful. He even forced Deputy Director Chen to make concessions." Liu Haizhong shrank his neck in fear, took two steps back, and prepared to slip away.

As soon as he turned around, Xu Damao screamed in the crowd: "Ouch, my butt hurts."

Brush brush brush.
Sharp gazes pierced into the bangs.

Liu Haizhong raised his hands high, wanting to cry but unable to, "I really didn't do anything!"

Deputy Director Li waved to his assistant, and when the assistant came over, he pointed at Liu Haizhong and said, "Does that fat guy have a problem with his thinking?
Ask the comrades in the Education Office to find out about the Women's Federation, and ask the comrades from the Women's Federation to pay a home visit to his home and find out the truth.

We don't allow gay sex in our steel mill!"

"Understood!" The assistant wrote down Deputy Director Li's order in his notebook.

After Liu Haizhong staggered away, the assessment of the eighth-level fitter in the steel rolling mill officially began.

Shearing machine is a machine that cuts metal sheets through shearing force.

As the name suggests, the six-meter shearing machine is the most advanced hydraulic swing shearing machine in this era.
And because it is equipped with the hot shearing of initial rolled square billets and slabs commonly used in steel rolling mills, the maximum thickness that can be sheared (δb<50kg/m㎡) is: 40 mm.

The pressure can reach 200MPa and the maximum shearing accuracy is 0.001mm.

The six-meter shearing machine is very large, as big as half a room.

Because the structure is complex and there is a certain degree of danger.

According to regulations, one person cannot operate the shearing machine alone. 1-2 people should coordinate the feeding, dimensional accuracy control and material removal, and one person should be in charge of the unified command.

Several seventh-level workers recruited their apprentices to help.

When the assessment started, the level 7 workers did not open the shearing machine directly, but squatted in front of the corrugated steel, touched the surface of the steel plate with their hands, and then pinched it with their fingers.

By touching and pinching, the seventh-level workers were able to figure out the material, density and thickness of the steel plate, and the data was more accurate than that measured by professional machines.

"Master Liu, according to the ranking, you go first."

A seventh-level worker in work clothes walked to the shearing machine with his apprentice and checked the lubricating oil, V-belt, handle, knob and button of the shearing machine.
Seeing that the old master seemed to be slacking off, Deputy Director Li wanted to urge him on.

Li Aiguo stopped him and asked, "This is the master, what's his name?"

Deputy Director Li was also confused and called the workshop director over.

Workshop Director: "His name is Zhou Gong. He has been a fitter for decades. Because of his low education level, he went to night school and got a junior high school diploma, which allowed him to participate in the promotion assessment."

Judging from Zhou Gong's gray hair, he must be over 50 years old. The fact that he still attends night school at such an old age shows his spirit.

Li Aiguo kept this name in his heart.

Zhou Gong spent a full ten minutes checking the shearing machine before turning on the button.

He is responsible for operating the shearing machine, and his apprentice is responsible for feeding the materials.

The two people cooperated very well. After a moment, as the shears of the shearing machine fell, the corrugated steel plate was cut into regular rectangles.

Zhou Gong turned off the machine, carefully cleaned up the iron filings, checked the shearing machine again, and then walked up to Deputy Director Chen:
"Report, fitter Zhou Gong has completed the assessment, please check!"

Deputy Director Chen was about to ask the examiner to come forward to check, but suddenly he thought of something and looked up at Li Aiguo: "Comrade driver, since this time we are providing excellent talents for your railway department, it stands to reason that you should be the one to check, so that you won't blame us for cheating."

Deputy Factory Director Chen has a square face and looks righteous, but he is too narrow-minded.

Li Aiguo is a train driver and knows nothing about mechanical processing. Deputy Director Li was about to stop Deputy Director Chen.

"As it should be." Li Aiguo suddenly stepped forward, looked at Zhou Gong and asked, "Master Zhou, do you mind if I use your micrometer and vernier caliper?"

"of course can."

Taking the tools from Zhou Gong, Li Aiguo came to the cut corrugated steel plate and used a micrometer and vernier caliper to take measurements.

He was skilled and his measurement method was standard. Deputy Director Li was amazed and said, "Driver Li, you also know this?"

"Machinery is the foundation of industry. We train drivers are also workers, so we naturally need to know a little bit." Li Aiguo smiled and reported the measurement data on the spot: "The mechanical accuracy is 0.002 mm."

Looking at the result, Li Aiguo immediately realized that he had found a treasure.

Mechanical accuracy is the difference between the actual value and the theoretical value.

The most direct cause of this difference is hysteresis, straightness and verticality.

In later generations, when high-precision CNC shearing machines were used, the accuracy difference could generally only be controlled within 0.005~0.02mm.

Even with the most advanced CNC shearing machines, it is difficult to control the accuracy difference below 0.005.

When Deputy Factory Director Chen heard the result, he frowned immediately: "0.002 mm? I remember that Lao Bai, an eighth-level worker in our fitter workshop, had a best record of only 0.003 mm, right?
Driver Li, is there something wrong with your measurement method? "

As soon as these words came out, the atmosphere suddenly became tense.

Everyone could see that Deputy Director Li first used the Qianmen Locomotive Depot to attack Deputy Director Chen.

Now Deputy Director Chen is trying to regain his face.

But the train driver was also stupid and was fooled so easily.

After realizing Deputy Director Chen's purpose, Deputy Director Li was not in a hurry.

Instead, he folded his arms and smiled heartily: "Old Chen, since you think Comrade Tiedao's measurement is problematic, why don't you let your people measure it themselves?

Deliberately accusing others without any evidence is not what a leader should do."

With just one simple sentence, the pressure was put on Deputy Director Chen.

But he was not in a hurry.

Although he was not clear about Li Aiguo's specific identity.

But a train driver can only knock on the wheels with a maintenance hammer. How can he understand what precision difference measurement is? !
Deputy Director Chen decided to choose a "confidant" to complete the measurement work.

"Comrade Yi Zhonghai, go and measure it again. Everyone is watching, so don't worry." Deputy Director Chen directly called on Yi Zhonghai's name.

When Deputy Director Li saw Yi Zhonghai walking out of the crowd, his face suddenly turned gloomy.

A while ago, whenever Yi Zhonghai had time, he would run to his office to express his loyalty to him.

Deputy Director Li also intends to cultivate his own manpower in the workshop and also wants to take care of Yi Zhonghai.

Who would have thought that since Deputy Director Chen became the team leader, Yi Zhonghai has disappeared.

It turns out that he had joined Deputy Director Chen!

This guy looks honest, but now it seems that he is a two-faced guy. He must not be trusted easily.

Yi Zhonghai also noticed Deputy Director Li's gaze.

But he couldn't care less at this moment.

Yi Zhonghai asked Jia Dongxu to help him get the tools, and he squatted in front of the corrugated steel and started working.

five minutes later.

Looking at the scale on the micrometer, beads of sweat broke out on Yi Zhonghai's forehead and his hand holding the micrometer began to tremble.

Deputy Director Chen saw that he had not finished the measurement yet, so he frowned and asked, "Master Yi, how is it?"

Yi Zhonghai raised his head and squeezed out an incredible sound from his throat: "Report, report. The accuracy difference is 0.003 mm."

boom.

The atmosphere at the scene suddenly became heated.

"I never realized that this train driver is also an expert in mechanics."

"That's right. If someone doesn't have some real skills, how can he be in charge of a project?"

Amid the discussions, Deputy Director Li laughed secretly in his heart.

This train driver can modify a steam locomotive and make furnace equipment. Can he be an ordinary person?

He looked at Deputy Director Chen and said, "Old Chen, how about you apologize to the railway comrades?"

Deputy Director Chen's face flushed, and he nodded at Li Aiguo, uttering a mosquito-like hum: "Driver Li, I made an empiricist mistake."

"You're welcome. Everyone makes mistakes sometimes. Let's continue the assessment."

Li Aiguo replied indifferently.

Deputy Director Chen breathed a sigh of relief and waved his hand to signal that the assessment could continue.

"Next, Master Yi Zhonghai from the fitter workshop."

Although Yi Zhonghai was well prepared, he was still a little nervous.

For no other reason than cutting boards is his weak point.

This damn Li Aiguo clearly doesn't want me to be an eighth-level worker. Yi Zhonghai complained in his heart, but he had to bite the bullet and step forward.

He walked to the shearing machine and suddenly turned his head: "Jia Dongxu, come and help the master."
