Zhou Jianhua lowered his head and thought about it, and the other master said, "Why don't we improve the method and try it again?" ”

Zhou Jianhua felt that he had just come to the machine repair class, and he was not good at stealing the limelight from Master Fang in terms of mechanical maintenance, so he did not directly say that he would try, but took a cooperative attitude, and wanted to tutor Master Fang to repair this chain well, so that he could not only make results, but also save face for Master Fang.

"How to change? It's hard to change......" Fang Guiping only replied casually when Zhou Jianhua said it casually.

"There is a way, the material of this mining chain has its unique requirements when doing heat treatment, if the process conditions can be met, I estimate that it can be used for more than half a month, and the problem should not be big." Zhou Jianhua prompted.

Hearing Zhou Jianhua say this, Fang Guisheng couldn't help but widen his eyes and exclaimed, "You will do this too?!" ”

Although Fang Guisheng had seen this junior high school student's ability to defy the sky in the maintenance of equipment and electrical systems, he never imagined that he still knew the heat treatment process, but now Zhou Jianhua said so confidently that he would try it again, which made Fang Guisheng's heart rise a little cool.

Fang Guisheng thought that he had been in the machinery industry for so many years, and now this mechanical maintenance job that belonged to his own specialty, he hadn't figured it out for many days, and the hairy boy in front of him actually said that he had a way to do better, which made him have mixed feelings in his heart, and he couldn't help shouting: Do you kid want to be so crazy?!

"You can give it a try!" Zhou Jianhua smiled faintly and said, "But we have to prepare something first......

At this time, Zhuang Minghui, who was listening to the conversation between Zhou Jianhua and Fang Guisheng while fiddling with the relay, couldn't help but interject: "Master Zhou, what do you want to prepare?" I'll help you get it! ”

Zhuang Minghui admired Zhou Jianhua so much since he saw Zhou Jianhua's martial arts in repairing the winch yesterday, and he believed that Zhou Jianhua, who had hidden his stunts, would definitely be a master he could often seek advice from in the future. Now when he heard that Zhou Jianhua was going to do the metal processing things that Fang Guisheng couldn't handle again, he immediately became excited, thinking that the time to witness the miracle had come again!

Zhou Jianhua turned his head to Zhuang Minghui and nodded with a smile, and then asked Fang Guisheng: "Master Fang, can we get J553 welding rod here?" ”

Zhou Jianhua can imagine with his toes that there will definitely be no J553 welding rod in this place, but this is an indispensable thing for repairing the chain link, and it must be there.

"We don't have this electrode, only the commonly used J422 electrode." Fang Guisheng replied stupidly.

"I mean, can we get it?" Zhou Jianhua emphasized again.

"This ...... It's a little hard, I'm afraid. Fang Guisheng replied in embarrassment: "Why do you have to use this kind of welding rod?" ”

Fang Guisheng remembers that when he used to work in his original unit, he had seen welders use J553 welding rods, but he had never been in contact with them, and his unit had no business contact with Tonglin Coal Mine. If you want to get this kind of welding rod now, the easiest and feasible way is to ask Director Chen to find it through Section Chief Yan of Changhong Coal Mine.

"This electrode is important!" Zhou Jianhua said: "In recent years, the commonly used large-scale round chain for mining is generally made of 25MnV steel, which is produced by regular manufacturers with resistance welding butt welding or flash butt welding. But we can consider using J553 electrode for welding, which can barely make do, which is important to improve the tensile strength of the chain link of this material! ”

Fang Guisheng didn't know the material of the mining chain very well before, but now that he heard Zhou Jianhua say it so clearly, he obviously knew the material and processing technology of this chain very well, and he was even more entangled in his heart.

But Fang Guisheng thought again, even with this electrode can not solve the main problem of chain link repair, the overall strength of the chain and the improvement of corrosion resistance and wear resistance, etc., ultimately have to rely on the heat treatment process, I don't believe that this little hairy boy really has such a great ability, can do better than himself. It's better to put some pressure on him to retreat, and just to suppress the arrogance of this little hairy child, lest he don't know how thick the road is. So he said:

"If you are really sure that you can fix this chain, I can help you go to Director Chen to find a way, but if Director Chen finally gets the welding rod and you can't fix it, how should I explain it to the mine manager at that time?"

Zhou Jianhua immediately understood what Fang Guisheng meant, thought about it and replied, "Master Fang, I understand your difficulties. In this way, you can directly tell Director Chen that this is my idea and what I asked to do. If I don't do it well when the time comes, Director Chen will naturally be on my head. ”

"How can that be done, how can you be held accountable alone." Fang Guisheng hurriedly explained: "I'm worried about whether you are sure that you can fix it, lest Director Chen have an opinion on you at that time, and in the end it will be thankless, so why bother." ”

"It's okay! Hurry up and talk to Director Chen! With the director's salary and bonus, we have to worry about him, don't we? Zhou Jianhua said half-jokingly, without the slightest intention of retreating.

"Okay, then I'll go talk to Director Chen." When it came to this, Fang Guisheng could only agree.

Fang Guisheng walked towards the mine manager's office and thought, this hairy boy really can't die in the Yellow River! Well, I'll see how you look foreign!

Zhou Jianhua didn't know what Fang Guisheng was thinking at this time, but he knew that Director Chen would definitely not give up this opportunity to try, so he immediately said to Zhuang Minghui: "Master Zhuang, can you help me find two stoves?" A coal stove, a wood stove, and some coal and wood for backup...... Uh, and urea, can you get it? ”

"Urea?" Zhuang Minghui looked away and said: "You can go to the canteen to find the stove and firewood, this urea is difficult, every household in the commune is short of chemical fertilizer, even if there is, it will not be left until this season......

"Oh! Then forget it. Zhou Jianhua looked at Zhuang Minghui slyly: "...... Can you find a basin or jar that can be used as a urine bucket or something? ”

Although Zhuang Minghui didn't understand the use of Zhou Jianhua's urea urine bucket, he didn't ask much, pursed his lips and nodded, and went out to find the things Zhou Jianhua wanted, he believed that Zhou Jianhua wanted these things to have his effect.

Fang Guisheng came back from Director Chen after a while, patted Zhou Jianhua's shoulder with a smile, and said in a slightly gloating tone:

"I found Director Chen, Director Chen is quite supportive of your idea, and the J553 electrode you want was really handled by him. Moreover, we don't have to take it ourselves, the chief of the technical department of Changhong Coal Mine Yan and the chief of the technical department of the mining machinery factory Wang will personally send it to you! Xiao Zhou, you can play big now! ”

"Oh?! How many welding rods do you have to send over in person? Director Chen's face is so big, are they so idle? Zhou Jianhua asked puzzled.

"Huh...... No, they're actually very busy......" Fang Guisheng picked up the teacup from the table and took a sip of water, then continued:

"Director Chen and Section Chief Yan are more familiar, so I asked him in the Changhong Mine Machinery Repair Class to ask if there is this welding rod, who knows that after asking Section Chief Yan, he said that he would send the welding rod over with Section Chief Wang of the Mining Machinery Repair Factory, and I don't know what the specific situation is - Director Chen said that they will arrive in about an hour."

"Oh, it's tight, we have to get ready!" Zhou Jianhua said to Fang Guisheng: "Master Fang, let's go our separate ways, please go and choose a spare link to take it off, and I'll prepare other things." ”

"Okay, I'll get the chainring." Fang Guisheng agreed.

Although Fang Guisheng is very reluctant that Zhou Jianhua can really surpass him, it is difficult to shirk in the face of Zhou Jianhua's normal and reasonable work requirements, at least on the surface, he still has to get by.

At this time, Zhuang Minghui had already found a broken ceramic jar to wash and bring it back, Zhou Jianhua took it and put it in the corner of the workshop, and asked everyone with a smile not to flow out of the "fat water", and try to accumulate as much as possible. Fang Guisheng didn't know why, and asked what kind of play this was, Zhou Jianhua smiled and didn't answer, only saying that it would be useful for a while.

Zhou Jianhua and Zhuang Minghui went to the canteen together, borrowed a briquette stove, carried a few ready-made coal billets and a large basket of firewood and put them at the door of the machine repair class, first set up the coal stove and lit the preheated briquette stove, and then went around to find a few broken bricks and stones to build a simple stove outside the workshop, dug some yellow mud and strengthened and sealed it around the simple stove, and also lit firewood to intervene in the heat.

At this time, Fang Guisheng also sawed down the selected chain link and braided it to the chain to be repaired, and Zhou Jianhua brought the chain over and put it on the coal stove that was not very hot, so that the chain link that needed to be repaired naturally drooped and rested on the burning coal, so that it gradually heated up with the slow increase of the furnace temperature.

Zhou Jianhua and Zhuang Minghui pushed the welding machine of the machine repair class to the door, and put an iron plate on the ground next to the stove to connect the ground wire.

Everything was ready, and a few people finally sat down to take a breath.
