Rebirth 2008: I Can Make Money Reading Chapter 47

Huazheng Valve Group has nearly 20 years of rich experience in valve production and manufacturing. It has 7 wholly-owned and holding subsidiaries, including 3 manufacturing entities and 2 trading companies. It is a national high-tech enterprise. The output value is about 500 million yuan.

Headquartered in H City, Jiangnan Province, it has a manufacturing plant, which is mainly responsible for the processing of gate and globe valves, including welding.

Recently, a batch of products was returned by a foreign Aman Oil Company PDO customer and fined $100,000.

At this time, the general manager of the company, the technical director of the group, the quality manager, the welding supervisor, the welding workshop supervisor, two deputy managers of the technical department and the purchasing manager were gathered in the conference room on the second floor of the office building.

The atmosphere in the conference room was depressing, and even the technical director, Mr. Chen, who likes to laugh at meetings, was full of worry at this time. At the age of 40, the top of his head was already bald.

General Manager Wang knocked on the table with his fingers: "Our company pulled the gate valve of Aman in the first half of the year, and there were five gates leaking. From the photos sent by the customer, it was the sealing surface of the welding seam that was cracked.

Moreover, on-site spectrometry was used to detect alloy elements, and the iron element of the sealing surface was seriously exceeding the standard, reaching 13.5%!

And what is the standard requirement?

Less than 5%!

Zhang Gong, you are responsible for the quality, you should first talk about what caused it. "

"Mr. Wang, the valves we sent out were all pressure tested and leaked in the workshop, indicating that there was no problem with the original test.

The sealing surface of the weld is cracked. The base material of the gate is chrome-molybdenum steel F11. The material itself has a relatively large crack tendency. Wu Gong should be more aware of this problem. "Zhang Gong organized the language and did not hesitate to throw the blame on Wu Ming, a welding engineer in the technical department.

"Fuck"

"Uncle Ni's!"

Wu Ming secretly scolded Zhang Gong, and the leader of the quality department knew that he would take the blame.

Seeing that everyone in the conference room was looking at him, especially his leader, Mr. Chen, before the meeting, he knew that he would be asked these questions, and he had already figured out how to answer them.

"Leaders, there is no problem with the welding process, which has been verified for many years. This chrome-molybdenum steel F11 has a high carbon equivalent and is indeed prone to cold cracks during welding. Therefore, it needs to be preheated at about 250 degrees before welding, and asbestos is used to keep warm after welding. Slow cooling, and then perform stress relief heat treatment at 700 degrees after welding.

If the surfacing layer is too thick and the stress relief heat treatment after welding is not done well, the internal stress of the welding will still be released during use, and cracks are normal.

As for the iron element exceeding the standard, it depends on whether the workers follow the welding process during manufacture. "

Wu Gong did not directly point out that it was a problem in the workshop, implying that the welder did not operate according to the welding process, and the process was prepared by him.

In fact, he himself knew that it was not easy to do.

If one layer is welded, if the element exceeds the standard, two layers must be welded.

If the welding is too thick, cracks are also prone to occur;

If the welding is too thin, the iron element is easy to penetrate, and it is easy to exceed the standard.

The customer requires less than 5% of iron, but their company can't do it. It is enough to ask for less than 10%. This is something that the general manager and technical director know. If you can hide it, you can hide it from the customer.

If this problem can be solved, that is, if the iron element is less than 5%, foreign orders will not be filled. After all, Chinese-made products are much cheaper than foreign ones.

However, at present, all valve manufacturers have not been able to solve this problem, including the leading valve factory Kawei.

Hao Jian, the head of the welding workshop, quickly explained: "The workshop has done preheating and post-weld heat treatment. Cracks may be a problem with the base material. These castings often have sand holes and shrinkage holes, which are prone to cracks."

Song Huan, the manager in charge of casting procurement, glanced at Hao Jian and despised his statement: "Hehe, Director Hao, you are going too far, there is a problem with the casting, you must have discovered it when you were welding, why didn't you contact the procurement department at that time? feedback.

If there is a problem, we can return it to the foundry. Why does the customer say that it is a casting problem when the customer finds the problem. "

The general manager hurriedly knocked on the table: "Okay, now is not the time to shirk the responsibility of any department, this matter has caused a very bad impression on the major customers, and the company has also been fined.

Mr. Chen, your technical department, see if there is a better way to completely solve the problem of surfacing STL. Last year, hundreds of thousands of them were found, all of which were excessive alloy elements and cracks. "

The general manager is the boss's brother-in-law, owns 5% of the company's shares, and has a great say.

Most of the private enterprises in Jiangnan Province are family-owned enterprises.

There may be fights within the family, but it is the same externally. When you do business, you can only grow big if you know how to stick together, so doing things will not damage the company.

Otherwise, the company has been established for so many years, and the company can't be so big, and everyone has parted ways long ago.

Mr. Chen smiled bitterly: "Mr. Wang, this problem has always existed, including the leading valve factory, and it has not been solved. Wu Gong, do you think there is a good solution?"

Wu Ming replied: "The welding consumables, castings and equipment of foreigners are better than ours, and they can only meet their requirements under strict process conditions.

Imported STL6 welding consumables cost at least 500 yuan per kilogram, which is too expensive, and it is not easy to buy. "

Without further explanation, even if it can be done, the cost will rise sharply, and it will be a loss-making business.

They were in a meeting when the door was suddenly pushed open, and a handsome young man walked in, wearing a light blue suit, his hair was neatly combed, and he kept a confident smile on his face.

This person is Mu Yang.

Huazheng Valve Group is Muyang's former owner, and their headquarters is only a 20-minute drive from Xinghai Company.

After the successful debugging yesterday, Muyang welded a few more samples. He came over this morning and planned to find the general manager to discuss OEM cooperation.

When he drove into the gate, he was stopped by the doorman, but he knew the name of the doorman, handed him a cigarette, and said that he had made an appointment with President Wang.

The doorman has been working in the company, even in 2022, so Mu Yang still remembered his younger appearance.

The old guard had never seen him before, but he recognized that the car Mu Yang was driving was a luxury car. He had eyesight. It was estimated that it was a big customer. He smiled and asked him to park in the customer's parking space. Foreign vehicles were not allowed to enter the production area.

The company only needs to register for outsiders to enter, but if they want to go out, especially when driving, they must strictly test whether they are carrying company items.

Muyang walked through the conference room and overheard about the quality problem of surfacing STL6.

After waiting for the right time, I knocked on the open door before pushing in.

"Mr. Wang, I take the liberty to interrupt, and I'm very sorry. I happened to hear your technical problem accidentally, and I can solve it!"

If they weren't worried about finding a solution to the problem, he wouldn't have entered the meeting.

Otherwise, this impolite behavior will most likely be kicked out.

If you want to find President Wang, you have to wait until after his meeting.
