Chapter 51 – Important Parts Should Use Good Steel

Chapter 51 Good use of steel for important parts

After the laser welding machine is settled, the next work is much easier for Zhao Guoyang, and he only needs to go all out to transform the drawings into real objects.

As soon as he went to work the next morning, he called people from the technical department for a short meeting and arranged the tasks at hand.

The technical department was divided into two groups, and Zhao Guoyang was in charge of leading some people to the workshop for production guidance. Hua Guosheng and Xu Dongfeng continued to disassemble the remaining drawings with two other technicians who could read pictures.

Actually, after working hard these days, Zhao Guoyang has broken down most of the drawings of C100, and almost all the difficulties have been solved.

He also discussed with Hua Guosheng about the remaining small things, and it shouldn’t be a big problem to leave it to the other party.

After the meeting, Zhao Guoyang went to the workshop for a tour, and then took a part of the disassembled drawings to the factory office to find the director Ma Jian.

The frame of the C100 curved beam motorcycle of Siyang Group is mainly welded by the main column, the main beam bend pipe, two rear beam pipes and two cable-stayed pipes.

Among them, the welding of the main column and the bending pipe of the main beam of the curved beam car are different from the main support pipe of the general motorcycle frame, and require higher strength and toughness.

Therefore, the material requirements for this part of the components are relatively higher.

On the drawing provided by Siyang Group, the requirement for this piece is Q345 steel, which is much stronger than the Q235 steel used for normal motorcycle frames.

But in Zhao Guoyang’s view, such an improvement is not enough. According to his previous life experience, the frame of a curved beam car has extremely high requirements for strength, even Q345 steel may not be able to meet it.

Therefore, in this trial production, he decided to use QSTE380TM with better performance.

This is a hot-rolled pickled automotive structural steel with good cold formability. It is usually used for automobile structural parts such as automobile girders and beams that require good cold forming performance and high or high strength requirements. It is used in motorcycles. On the shelf, it is rare.

The performance of this kind of steel is good, but the price is also high.

The key point is that it is still difficult to buy small batches in the market. Usually, the consumption of this kind of steel by automobile companies is calculated on the basis of hundreds of tons. If you want to buy tens of kilograms, people really don’t necessarily care about you.

As far as Zhao Guoyang knows, there should be no such steel in the inventory of his Hongda Machinery Factory. He has no choice but to report to the factory manager Ma.

As soon as he walked to the door of the office, the sharp-eyed Director Ma saw Zhao Guoyang.

“Hey, Guoyang, you came just in time, hurry up, come and help me see why this radio is not working.” Ma Jian waved to Zhao Guoyang.

Zhao Guoyang felt a little helpless about this, but he had business to do. But there’s no other way. If someone asks you to look at the radio for me as the director of the factory, how can you not give me face?

After taking the radio in Ma Jian’s hand, Zhao Guoyang briefly adjusted it twice, and after a while, he discovered the problem.

“Director Ma, do you have a screwdriver?” Zhao Guoyang asked.

“Yes, yes!” Ma Jian took out the cross from the drawer and handed it over.

After Zhao Guoyang took it, he put the radio on the table, and quickly removed the cover.

Seeing his beloved radio disintegrated in an instant, Ma Jian felt a little distressed, and couldn’t help asking: “Guoyang, can this…can be fixed?”

Zhao Guoyang nodded confidently and said: “Don’t worry, Director Ma, it’s just that there are sundries in the earphone jack, which makes the spring piece not in good contact and makes the speaker silent. Just re-adjust the length of the spring to make it stretch moderately. That’s it.”

After finishing speaking, Zhao Guoyang clipped off a piece of spring, then carefully reconnected it to the headphone jack, and finally put the shell back together.

“Okay, it should be all right. Factory Manager Ma, please try again!” Zhao Guoyang handed over the completed radio to Ma Jiandao.

“Huh? It’s that simple?” Ma Jian answered the radio in disbelief.

As Ma Jian turned on the switch of the radio, the smooth voice came from inside again.

“Hey, Guoyang, okay, your skills are not inferior to home appliance repair shops! Why, did you learn this in school?” Ma Jian patted Zhao Guoyang on the shoulder and said with a smile.

“Well… At that time, I had a lot of time, so I liked to toss around and understand a little bit.” Zhao Guoyang scratched his head and said.

In fact, let alone radios, communication equipment on airplanes and large transport ships is a piece of cake for him.

In his previous life, he dabbled in a wide range of applied technologies, not only in mechanics, but also in electronics and radio. If it weren’t for his age, he would have absolutely no problem appraising an academician.

After finishing the radio, Zhao Guoyang finally had the opportunity to explain his intentions to Director Ma.

After hearing Zhao Guoyang’s request, Ma Jian was puzzled for a while: “Guoyang, I know this QSTE380TM steel is a high-quality steel with a high price. It is rare in the steel market in a small city like Ninghai. I don’t know. Understand why you must use this kind of material, obviously the Siyang Group does not have such special requirements?”

Zhao Guoyang explained his thoughts patiently, and finally said: “Director Ma, if Q345 steel is actually used, there is no big problem in terms of strength. But Minister Liang of Siyang Group said that their C100 curved beam car , it is very likely to be exported abroad…”

“What’s wrong with exporting abroad?” Ma Jian still didn’t quite understand.

“Director Ma, I think about it this way. The physique of Europeans and Americans is generally taller and heavier than our Asians. If the underbone car of Siyang Group is really exported abroad, it will not be as strong as ours in the past. standard to measure.”

“The other parts of the frame are fine, but the main pillars and main beam bends are the central axis of the entire frame. I think there is nothing wrong with using better materials.”

Zhao Guoyang paused, and continued to explain: “In addition, the frame we trial-produced this time will eventually be used for the Siyang Group for experimentation.”

“It is even very possible that we will compare it with the frame of that Shunxin Machinery Factory. If we outperform each other in terms of strength, it will undoubtedly give our factory a lot of impression points.”

“Finally, our good materials are not in vain. When the production cost is raised a bit, the people of Siyang Group will understand.” Zhao Guoyang finally laughed.

Seeing that Zhao Guoyang has taken all factors into consideration, how could Ma Jian object?

He nodded again and again and said: “Yes, I think it will work. As far as I know, only a steel trading market in Guangling City sells QSTE380TM steel. In this way, I will ask Wang Cheng, who is in the procurement department, to prepare it, and we will set off immediately .”

“By the way, Guoyang, if you have nothing to do, you can go with us later. After all, it is the same QSTE380TM, and there are different specifications. What kind of products do you need? If you are here, you can communicate with them, right?” Ma Jian continued.

Zhao Guoyang thought about it, anyway, there was nothing to look at the drawings, so he agreed.

Besides, he also plans to visit the steel market recently. After all, the hairpin project he is considering also needs to buy raw materials.
