Big Country Intelligent Manufacturing

These days, Xu Zhenming has been busy with the company's main business, and has delegated the responsibility of Sun Ziliang and Hu Chunmei to the business of the first machine repair plant of Nan'an Iron and Steel Group.

The surfacing rough roll has completed the heat treatment process and is sent back to Yiming's car processing workshop for processing.Counting days, this and the rough roll should have completed the finishing process.If there is no quality problem, it should be shipped out.

At this point in repairing this rough roll, Yiming’s task has been completed.The following procedures should be taken care of by the first machine repair shop. After passing through the heat treatment again, it can be put on line for trial operation.

Thinking of this, Xu Zhenming stopped, smiled and asked Gao Jianjun: "Old man, how is the situation? Does the roughness of the roll surface meet the technical requirements?"

Gao Jianjun has not yet replied, but Xiao Jian in the crowd spoke first: "The quality inspector has not tested yet, and no one dares to draw conclusions!"

This guy has some background, he likes to gesticulate, he is a sideways character in the first machine repair shop.He feels very good about himself and likes to intervene in everything.

Gao Jianjun originally wanted to chat with Xu Zhenming and discuss how to make new rough rolls.

Seeing Xiao Jian yin and yang talking weirdly, he rushed to speak in front of him.He was a little unhappy, and gave Xiao Jian a look.Then, he walked to Xu Zhenming's side and smiled slightly: "Xiao Xu, the rough roll just got off the CNC grinder. You have to wait for the roll to cool down before checking the data!"

Seeing this scene, Xiao Jian became more and more bitter towards Xu Zhenming.

He didn't know why Gao Jianjun liked Xu Zhenming so much, and he spoke amiably.But for their colleagues in our factory, they have a bad attitude and demanding."Damn! What kind of ecstasy did Xu Zhenming pour Gao Jianjun into?" He thought depressed.

"Elder Gao, dear masters! Since the work piece has not cooled yet, please sit in the conference room on the first floor and have some tea!"

Xu Zhenming glanced at Xiao Jian with a pale face and smiled and invited everyone to take a rest.

He knew that it was inappropriate to inspect the rough roll that was just off the machine at this time, and the data would be more accurate when the rough roll cooled down.

The temperature of the workpiece running at high speed on the machine tool is very high, it will expand, and the size data will shrink after cooling.The experienced old technician will judge the thermal expansion of the workpiece according to the size of the workpiece and the speed of the machine tool, and reserve a certain margin.After the workpiece is cooled, the size data of the machined surface is just within the tolerance range.

The heavy-duty CNC grinder operators of Yiming Company are veteran technicians, and Xu Zhenming is very attentive to their skills.Therefore, he calmly led everyone to the large conference room on the first floor of the office building, and accompanied everyone to drink tea.

"Xiao Xu! If we re-forge a rough roll blank, what material should we choose?"

At this time, Gao Jianjun blew the green tea leaves in the teacup and asked Xu Zhenming to give his ideas.

He has tried many materials, such as high chromium alloy steel, high chromium cast iron... etc. There are no fewer than a dozen materials, and none of them succeeded.For this matter, he could not eat well, sleep well, and his hair became a lot grayer.

"laugh…"

Seeing Xu Zhenming preparing to speak with a calm expression, Xiao Jian couldn't help but curled his lips and sneered.

He couldn't help being amused, thinking that Gao Jianjun was rushing to the doctor because of his illness. He actually lowered his body to ask Xu Zhenming, a secondary school student who had just graduated for half a year."This old guy has fainted!" He despised Gao Jianjun in his heart.

Seeing Xiao Jian's little gesture of curling his mouth, Xu Zhenming couldn't help but sneered: "This straw bag has been irritating with yin and yang, and seems very dissatisfied with me. Give him some color first!"

Thinking of this, he smiled at Gao Jianjun, and then pointed to Xiao Jian who was sneering at him and said, "Old man! Xiao Jian will definitely give you a satisfactory answer to this question you asked! He is a top student in our class and takes the first place every year. One!"

"I, I don't know Elder Gao!"

Suddenly assaulted by Xu Zhenming, Xiao Jian blushed immediately and kept talking.He doesn't even know the types of alloy materials, how could he know these?Therefore, he declined in a flustered manner, and his eyes were sharp when he looked at Xu Zhenming.

"Just him, hehe...Does he know the performance of high-chromium alloys? Do you know the performance difference between high-chromium cast iron and high-chromium alloys?"

Gao Jianjun glanced at Xiao Jian who was blushing, and said with a smile.

Judging from his facial expressions, he looked down on Xiao Jian at all!

Seeing Gao Jianjun saying this to Xiao Jian, the quality inspector and technician He Yan in the conference room both pursed their lips, holding back a smile.These people all know Gao Jianjun's temper, and he speaks without mercy.Seeing Xiao Jian as a shield today, he was naturally cheating.

"Xu Zhenming, I don't know what materials are used to make the rough rolls! Do you know? You are the same! Fifty steps and a hundred steps, why do you want to tell me?"

At this time, Xiao Jian was a little annoyed, and asked Xu Zhenming with a green face.

All along, everyone has centered on him, and he has become arrogant.Few people in the No. 1 Mechanic Repair Factory offend him, and the customers of the No. 1 Mechanic Repair Factory dare not offend him.Today, Xu Zhenming prevented him from getting off the stage.

Therefore, Xiao Jian was a little gaffe at this time, and Xu Zhenming became angry from embarrassment.

He Yan and Xiao Jian are friends with each other.

I don't know what the reason is. Since Yiming Company took over the rough roll research business, she has taken the initiative to alienate Xiao Jian, and she feels a little disgusted with Xiao Jian from the bottom of her heart.Every time Xiao Jian said something bad about Xu Zhenming in her ear, she couldn't help but refute a few words.

He Yan knows all this today.She thinks that Xiao Jian is actively looking for things, begging to be bored.By now, she has not treated Xiao Jian as her boyfriend.This is too shameful!

"Gao Lao! Nippon Steel's roughing rolls maintain their national traditions and use less materials! Because their metallurgical technology is good, they can produce small and high-strength roughing rolls. If we want to localize, use the same material Can't achieve this effect..."

At this moment, Xu Zhenming didn't even look at Xiao Jian, but watched Gao Jianjun express his thoughts.

He believes that the main material of the rough roll should be the same as the original factory, choosing high-chromium alloy steel.In addition, some other alloying elements should be added to improve the performance of the rough roll.

"Who want to add those alloying elements?"

Hearing this unusual conclusion, Gao Jianjun was very interested and asked Xu Zhenming.

"I personally think that two elements, molybdenum and vanadium, should be added, and a small amount of rare earths should be added! Of course, the specific formula can only be determined through experiments!" Xu Zhenming said his own speculation, and did not hide it.

The two alloying elements of molybdenum and vanadium can improve the strength of the workpiece, and many alloy materials are often used.Rare earth is gold oil, and many special workpieces can be used.

What Xu Zhenming said was often seen in later alloy materials.

After listening to Xu Zhenming's analysis, Gao Jianjun's eyes lit up, he patted his thigh and said, "Xiao Xu, your idea is very novel, you can try it out!"

He is the person in charge of the localization of rolls. He has tried a variety of material formulations and naturally knows the performance of these alloy materials.

This subject is still relatively advanced nowadays, and all steel companies are groping.In another ten years, the technology of roll repair and self-manufacturing of rolls is not uncommon, and any small factory can undertake this obligation.At that time, the binding machines on the imported production line could all be made in China, let alone the accessories like rolls.

Everyone was very surprised to see that Xu Zhenming could make Gao Jianjun take it seriously.They all looked at Xu Zhenming curiously, wondering in their hearts: "How amazing is Xu Zhenming? Even seniors believe him! Nan'an Technical School is not a prestigious school. An ordinary secondary school student actually understands that. Much knowledge?"

Seeing this scene, Xiao Jian's face became even more ugly.He blushed for a while, then his face was pale again, looking very wonderful.He was a little afraid to provoke Xu Zhenming, so as not to provoke his upper body again.

However, He Yan was red-faced, feeling very face-saving, and thought proudly, "Xu Zhenming is so high-level! You deserve to be a top student in our school!"

After the episode, Xu Zhenming led everyone into the heavy-duty factory.

This time, the quality inspectors of the No. 1 Machine Repair Factory inspected very quickly.Seeing that the data of the rough rolls are all within the tolerance range, they want to stop work soon.

However, Gao Jianjun disagreed, and said sternly: "You use the instrument to measure the surface of the roll again. You must work carefully! You did a good job in the last non-destructive inspection, and you can't relax this time!"

"Huh? Oh...Old man!"

The quality inspectors are very hurtful.

"Old Gao, we were looking for faults last time, so be careful! This time, hey..." They all thought depressed.

No matter how the inspection is done, the rough rolls processed by Yiming Company meet the tolerances and the data is perfect.Seeing this situation, Gao Jianjun left with satisfaction.Along with it, there is also the 2200 roughing roller repaired by Yiming Company.

In the afternoon two days later, Xu Zhenming received the invitation of Jianjun to participate in the commissioning of the rough roll on-line trial operation at the Medium Plate Plant of Nan'an Iron and Steel Group.

For this reason, the medium plate plant, which is undergoing overhaul, started up one day in advance to inspect the repaired rough roll to see if it is in normal production and has withstood the test of the harsh environment.

"Unlock the automatic joint adjustment, and the manual feeding test begins!" Seeing the red billets rolling in, the director of the operation workshop directed the operators to debug this 2200 rough rolling mill.

After the billet passed, everything was normal for the 2200 rough rolling mill, and all data were all right.

Subsequently, the director of the operation workshop asked the operator to select the automatic mode, and the entire production line began automatic trial production.

After a billet passed, the condition of the 2200 roughing mill was normal, and the workers at the end of the production line reported that the data of the pilot plate was normal, and the surface finish was within tolerance.

After half an hour, everything is normal!

After an hour, the situation is still normal!

By now, everyone knows that the 2200 roughing mill rough roll repair project has been successfully tackled.Everyone smiled and applauded, walked up to Gao Jianjun and shook hands with him.

Seeing this situation, Xu Zhenming turned and left with a smile.

He knew that with the success of the repair of this rough roll, Yiming had added another core business to repair the rolls of all production lines for Nan'an Iron and Steel Group.

Roll repair is a high value-added business, it's very fat!

"Xiao Xu, wait for me!" Seeing Xu Zhenming leaving, Gao Jianjun laughed and waved.

Seeing this situation, the leaders of the China Board Factory asked in amazement: "Who is that young man? Old man is so kind to him!"

"His name is Xu Zhenming, and he is the general manager of Yiming Company! Our rough roll was successfully repaired by him with a plan!" He Yan, who knew the inside story, reported the story to the leaders.

"Yiming Company? I haven't heard of it! Is their company better than the No. 1 Machine Repair Factory?"

"General manager? Xu Zhenming looks like he is only eighteen or nine years old, how can he become a general manager?"

"No matter how old he is, whether the company is famous or not, it is good to be able to repair the roll for us!"

The leaders at the scene were all talking about Xu Zhenming and Yiming Company.

Ever since, the names of Yiming Company and Xu Zhenming were spread in Nanjing Iron and Steel Group Company within a day.
