Seeing us coming in, Mr. Li stood up and wanted to give up the main seat to my dad. Even if he had never seen a big scene, he knew the ceremony, but his dad resolutely declined and sat down beside him.
My brother and I sat next to my father, and next to Mr. Li was his daughter Li Fangyun, and then Zhao Yongqiang, which meant that Zhao Yongqiang and I were next to each other.
"Let me introduce to you. I am now mainly responsible for company management and procurement. In the future, Li Yuwei will be mainly responsible for assisting me in the procurement work. This is Li Fangyun, the company accountant. She is responsible for the company's financial affairs. This is Zhao Yongqiang. Mainly responsible for the sales of the company."
After introducing the people around me, I looked at my father again, "This is Li Yuwei's father. He passed by and stopped by to have a look. The main reason is that Li Yuwei just came out of work and was worried. This is Li Yuwei's older brother, Li Yuxiong, who should be studying at Zhengzhou University. Three?"
"Yes, Mr. Li." My brother said.
"It's rare for you to come here once. Please forgive me for the poor hospitality. Let's not drink at noon, so as not to delay things in the afternoon, let's have a good drink in the evening." Li Yonghao said.
"Mr. Li is too polite. Yuwei and I have already agreed that I will go to the Jiantuozi construction site in the afternoon, and his brother will return to the city to take the train back to school in the afternoon. The school has started there and there is no further delay." Dad said quickly, although Knowing that the other party is being polite, it is still necessary to explain.
"Are you in such a hurry? If you're not too anxious, we'll stay at night, and it won't be a day's time." Li Yonghao said again.
"It really can't be delayed anymore. The construction site has already reached more than three floors. I thought I didn't need an electrician to just run the open wire. Considering the safety issue, I have made changes in the future. In fact, I have been urged twice when I came here. I'm really sorry." Dad said politely, this time the boss is not good at inviting again.
Considering the time issue after the meal, the boss directly asked Zhao Yongqiang to drive his brother Li Yuxiong to the bus stop, and then drove his father to Jiantuozi. As for me, I had to follow him to Jiantuozi.
After looking at the working environment and living conditions of the construction site, Zhao Yongqiang was really surprised that I could persist on the construction site for more than a month. My endurance seemed to be beyond his imagination. After returning to the company, I went back to the office directly. As for Zhao Yongqiang, he was greeted by the boss to leave.
After all, I just got involved in this business and didn¡¯t know much about it, so I contacted the business of several factories I knew in the afternoon, then changed into work clothes and went to the workshop. The workshop director is He Jianli I mentioned earlier.
"Master He, I heard that the rollers are changed today, so I'll come over to have a look." Seeing Director He, I said quickly, and at the same time took out the cigarette in my pocket and lit it for him.
"What are you doing here if you don't stay in the office in this hot weather?" Director He said.
"Didn't I tell you all the time that day, I want to come to the workshop to learn from you. Maybe I won't leave the workshop to rely on this technology for a living, but when I sell goods, at least I won't be called a layman. When you meet someone who is knowledgeable, you won't be laughed at." I said with a serious face.
"I thought you were just saying, you see, my whole body is full of oil, who is as cultured as you who would like to learn this. This is the last coil of strip steel, and the roll will be replaced when this coil is used up. The rollers are getting old and should be replaced, or the diameter of the pipe is affected, come over and see that the outer diameter is close to exceeding the standard.¡± After speaking, he took out the caliper and took me to the packing place.
"This is called a vernier caliper, have you used it?" Director He asked.
"I know, I used it when I was in school." I said quickly.
"Then it's easy to handle." In the middle of the conversation, we had already arrived at the packing table, and directly clamped the outer diameter of the steel pipe with a caliper. The outer diameter of the heating pipes in our home has requirements for the outer diameter."
"In addition to requiring the steel pipe not to leak under a certain water pressure, the ellipticity of the steel pipe also has a fixed standard based on the outer diameter. This needs to be measured in this way." After speaking, Director He waved to another worker on the packing table.
The other party pushed the steel pipe held by Director He with his hand, and the steel pipe rolled down the slope of the platform to the packing shelf below. The outer diameter of the steel pipe was constantly changing with the caliper, and the difference between the maximum value and the minimum value was only about 0.4 mm.
"We usually say that the outer diameter is 48mm. In fact, the state stipulates that it is 48.3mm, and the allowable deviation is 0.5mm. Although we do not have such strict requirements for scaffolding pipes, our boss still strictly produces according to this standard. Even now The roll should be replaced, and the outer diameter has not exceeded the standard." Director He said.
"Why doesn't the boss produce that water retention pressure???Steel pipe? "I asked casually.
"Everyone has his own aspirations. This requirement is low and there is no need to bear the risk of quality, haha!" After speaking, he took me back to the place where the material was loaded. Surrounded.
"Let's do it, replace it as soon as possible and start production sooner." He Jianjian said, with his instructions, everyone immediately took the wrench and started dismantling the production roll. I looked around and it seemed that there was really nothing I could do to help, so I could only stand aside and watch. They disassemble the rolls. Director He also saw my situation and smiled without saying a word.
As for him, he also stands on the sidelines and watches. The time when it can play a role is to debug after the roll is replaced. Being able to debug the unit to the best condition in the shortest time and at the lowest cost is their real ability as workshop directors.
? After the workers replaced the rolls, He Jianli began to debug each set of rolls one by one. I could only stare at the side and couldn't help at all. It took about half an hour.
After the establishment and commissioning of He He, the workers have already brought the uncoiled steel strip and put it on the platform of the leveling roller. As the roller slowly rotates and enters the unit, the whole speed should be more careful, lest the edge of the strip steel will scratch the roller. Leave traces, which will directly image the finish of the tubes produced later.
"Our numerical control platform can control the tube speed, and it can also control the power of the high-frequency welding machine. These two quantities must be kept in balance. The higher the output power of the welding machine, the corresponding tube output speed must also be increased, otherwise the Weld nodules will form on the inner wall.¡±
"If the output speed of the pipe is too fast and the power output of the welding machine does not keep up with it, it is easy to cause weak welding or missing welding, which is what we call a split pipe. If the length of the leaking welding is very short, it is difficult to find it. Once it is rusted or water is injected It is very obvious, and pickling and galvanizing will also enlarge the weld seam, of course, the shelf pipe is not galvanized."
Director He adjusted the pipe speed and the output power of the welding machine while talking, and I watched him operate step by step, and stopped when the pipe speed reached 65 m/s, and then took me to the back road for quality inspection and packaging. place.
"Did you see it? This is because the power is too high and the speed of the tube is not up to speed, resulting in the temperature of the weld joint being too high to melt and drip down. People call it a welding wart." Director He squatted on the ground and pointed to the inner wall of the welded tube on the packing table. .
The welding ribs on the outer wall of the steel pipe have been scraped flat by the scraper, and the surface is as smooth as other parts of the steel pipe. As for the welding ribs on the inner wall, they are preserved, but some places have formed the shape of water droplets and are about to drip down.
"After this is adjusted to the best state, the welding rod on the inner wall will become a very flat line, which is about 0.3mm higher than the inner wall. It looks like a tendon, which is why everyone is used to calling it a welding rod. .That's my guess. Haha" Director He said, and I also laughed.
"There is a factory in Tianjin that scrapes the inner welding bars. The welded pipes produced look not much different from the seamless pipes, but the pressure resistance is much worse. Many people call them fake seamless pipes. I haven't heard that there is such a thing in Tangshan. .¡± Director He added another sentence.
"Is there a big market for this thing?" I asked curiously.
"I don't understand this. It seems that the market is not small. Those who buy this thing are trying to get cheap. If something happens, no one is willing to take responsibility, so everyone who sells this has to be careful and don't fall into other people's pits. Do it Business is the same as being a person, you can't harm people's minds, but you can't be regarded as a fool." Director He said.
"Master He, how many years have you been doing this? Have you taken any apprentices?" Watching the steel pipes roll down from the packing table one after another, the rhythm of production finally returned to normal, and my little thoughts came up again. (Remember the site URL: www.hlnovel.com
