"Jiang Gong, I've brought you everything."

After a while, Hu Dahai came to Jiang Yan's office with a pair of bottles and cans.

"Get here, I'll mix it in a while, you take a good look, if you don't ask me, this recipe will be handed over to you in the future, and you will mix it."

Jiang Yan beckoned Hu Dahai to put the things he brought over on his desk.

After he put the things on the table, Jiang Yan began to get busy preparing Q/YS.112 chemical copper plating solution, and Hu Dahai, who was observing from the side, asked Jiang Yan some questions from time to time, and Jiang Yan also answered them to him one by one.

Under Jiang Yan's guidance, he also tried to mix this chemical copper plating recipe once.

"Let's go! Let's take a look at the production workshop. ”

Jiang Yan took the helmet and greeted Hu Dahai, who was still sorting out his notebook.

As the saying goes, a good memory is better than a bad pen, when Jiang Yan was teaching Hu Dahai's formula, he clearly recorded every step.

"Jiang Gong, just come." Hearing Jiang Yan's greeting, Hu Dahai hurriedly closed his notebook and followed Jiang Yan to the production workshop.

"Jiang Gong, this is Qin Ming, the director of the production workshop, Director Qin."

When he came to the production workshop, Hu Dahai pulled a worker who looked five big and three thick to introduce Jiang Yan.

Jiang Yan heard his name and subconsciously glanced at him.

I was thinking in my heart, and I didn't know what the old man of his family thought This name is the same as the name of the thunderbolt fire Qin Ming in the Water Margin.

followed Hu Dahai next to him and said, "Jiang Gong, his name is familiar!" It is the same as the name of the thunderbolt fire Qin Ming in the Water Margin. At that time, I was shocked when I heard it for the first time, don't you say, not only does he have the same name, but his temper is also exactly the same, quite hot. It's a well-known hard-working Saburo in our factory. Their workshop completes the best production tasks every year. ”

"Hu Gong complimented, hello Jiang Gong, I'm Qin Ming." Qin Ming said and stretched out his hand to Jiang Yan.

Seeing Qin Ming stretching out his hand, Jiang Yan grabbed his hand and said, "Hello Director Qin, I'm Jiang Yan." ”

"Don't call me Director Qin, just call me Lao Qin like Hu Gong."

After speaking, he smiled heartily, like that, it was really bold.

"Okay Lao Qin, you need to make a copper clad laminate today, you can arrange it."

Hearing Hu Dahai's words, Qin Ming patted his chest and said, "No problem, Jiang Gong, Hu Gong," just now a furnace of molten steel was refined, let's use this furnace of molten steel to tie copper steel, I will arrange it immediately." ”

After saying this, he didn't say hello to Jiang Yan, and ran over directly to make arrangements.

"It's really hot." Jiang Yan looked at his back and said.

"Listen, stop suppressing." At the exit of the rolling mill, looking at the copper-clad steel with different shades of copper-clad steel, Jiang Yan hurriedly stopped.

Seeing the copper-clad steel, Jiang Yan understood, what he thought was too simple, looking at the situation, it was not a matter of chemicals, it should be a problem of pricking.

Jiang Yan told Hu Dahai that the technology of copper-clad steel is simply to use metal powder to roll copper-clad steel plate technology to produce copper-clad steel plate. Copper-clad steel plate refers to a bimetallic plate product that combines metal copper powder and steel plate into one by rolling technology.

In detail, it includes raw material pretreatment, powder composite rolling, diffusion heat treatment, cold rolling, annealing, leveling, slitting, surface treatment, packaging and other steps.

Metal powder rolling can realize both powder-powder composite and powder-plate composite; It can be single-sided composite or double-sided compounded; The thickness of the composite layer can be controlled at will. The composite layer does not produce brittleness and can be completely deformed. The thickness of the composite panel is not limited. The copper-clad steel bonding of metal powder rolling belongs to metallurgical atomic bonding.

The copper-clad steel plate products produced by this method have high binding strength, wide range of application and many varieties, and are also the most suitable method for the production of copper-clad steel in the country.

"Lao Hu, tell the worker master to do it again, and you will make a record."

After Jiang Yan finished speaking, he took Hu Dahai to the place where the workers processed the steel in the early stage.

If the steel wants to be combined with copper cladding, it must be pre-treated, and the matrix steel belt needs to be derusted, degreased, degreased and texturized with a steel belt surface cleaning machine.

Nowadays, there are no such machines in the factory, so they can only be processed manually.

When the workers were processing the matrix steel, Jiang Yan took Hu Dahai to the copper powder that was ready to pour copper into the matrix steel.

As copper powder for copper plaminization, there are still strict requirements, and the composite copper powder needs to be graded, proportioned, annealed, and dried, so that the treated copper powder can be used for copper pouring.

After seeing that there was no problem with these two parts, Jiang Yan instructed the workers to start tying.

After the treated steel belt is uncoiled by the uncoiler, it goes through the processes of leveling, guiding, and rectifying to make the matrix steel belt smoothly enter the distributor and the powder rolling mill from the uncoiler. Use the distributor to control the flow rate of the composite copper powder, the uniformity of the cloth, the thickness of the composite layer and other factors. The primary-rolled composite belt enters the winder after passing through the steering device.

Jiang Yan took the flashlight and looked at the spout sprayed with copper powder, and his face changed.

"Pause feeding." Jiang Yan turned his head and yelled.

As soon as Jiang Yan's words fell, the machine that was still rumbling stopped working.

"Jiang Gong, what's wrong", Hu Dahai and Qin Ming ran in front of Jiang Yan at the same time, asking why they stopped.

"You see, the copper powder is sprayed unevenly, it should be a problem with the air vent, Hu Gong, prepare the tools, I'll take it apart and take a look."

Hearing Jiang Yan ask for tools, Qin Ming next to him hurriedly asked the workers to bring a complete set of disassembly tools.

Jiang Yan took the tool and started drying. After a while, Jiang Yan took out the nozzle and took a closer look at the opening, and said to Hu Dahai: "It's the problem of the nozzle, you see that the nozzle of such a nozzle is too big, and the copper powder is sprayed unevenly." ”

"Jiang Gong, are we going to set up a new sprinkler?" Hu Dahai then asked.

Hearing Hu Dahai's words, Jiang Yan nodded.

Then Jiang Yan spoke again: "Little problem, Hu Gong, you help me get some paper and pen, and I'll draw a new nozzle." ”

Jiang Yan casually found a workbench, and in front of Hu Dahai and Qin Ming, it took less than five minutes to draw a drawing of a sprinkler.

Jiang Yan put away the drawings that had been drawn and said to Hu Dahai: "You go to Master Sun Deshui and ask him to produce ten such nozzles immediately according to such drawings, and I have already indicated the specific parameters on the drawings." ”

After Jiang Yan finished speaking, he handed over the drawings to Hu Dahai.

After Hu Dahai got the drawings and left, Jiang Yan turned his head and spoke to Qin Ming, who was standing there.

"Lao Qin, help me find a few young and strong division of labor, I need to remove the four nozzles inside, the casing is too heavy, I can't handle it alone."

"No problem, Jiang Gong, I'll find you a few workers to come over."

After Qin Ming finished speaking, he ordered the names of individual workers in front of Jiang Yan, and when these people came to Jiang Yan's face, Jiang Yan found that the workers Qin Ming arranged for him were really powerful.
