Siheyuan starts from a better life

Chapter 260, troubleshooting

"Jiang Gong, I brought you everything."

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

"Bring it here, and I'll make it later. Take a good look and ask me if there's anything you don't know. From now on, this recipe will be handed over to you, and you will make it."

Jiang Yan asked Hu Dahai to put the things he brought over on his table.

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

Under Jiang Yan's guidance, he also tried to prepare the chemical copper plating formula once.

"Let's go! Let's go to the production workshop to have a look."

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

As the saying goes, a good memory is not as good as a bad pen. When Jiang Yan was teaching Hu Dahai's formula, he recorded every step clearly.

"Jiang Gong, come here." Hearing Jiang Yan's call, Hu Dahai quickly 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 dragged a worker who looked average and rough to introduce to Jiang Yan.

When Jiang Yan heard his name, he subconsciously glanced at him.

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

Hu Dahai followed him and said, "Jiang Gong, his name is familiar! It's the same as the name of Thunderbolt Qin Mingfen in Water Margin. I was shocked when I heard it for the first time. Don't tell me, he Not only the name is the same, but also the temper is exactly the same, quite hot. It is the famous Desperate Saburo in our factory. Their workshop is the best in completing the production tasks every year."

"Gong Hu praised you, hello Jiang Gong, I'm Qin Ming." Qin Ming stretched out his hand to Jiang Yan while speaking.

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

"Don't call me Director Qin, just call me Old Qin like Mr. Hu."

After finishing speaking, he smiled heartily, that way, he was really bold and unrestrained.

"Okay, old Qin, I 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, Mr. Jiang, Mr. Hu." Just now, we just smelted a furnace of molten steel, and we will use this furnace of molten steel to bind copper-clad steel. I will arrange it right away. . "

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

"This is really hot and fast." 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 color, Jiang Yan quickly stopped.

Seeing the copper-clad steel that came out, Jiang Yan understood that what he thought was too simple. Looking at the situation, it was not a matter of chemicals, but a matter of binding.

Jiang Yan told Hu Dahai that the copper-clad steel technology is simply to use metal powder rolling 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 through rolling technology to synthesize the two metals into one.

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 composite; the thickness of the composite layer can be controlled at will.The composite layer does not produce brittle compounds and can be deformed completely.The thickness of the composite board is not limited.Copper-clad steel bonding by metal powder rolling belongs to metallurgical atomic bonding.

The copper-clad steel plate produced by this method has high bonding strength, wide application range and many varieties, and it is also the most suitable method for producing copper-clad steel in the country at present.

"Old Hu, tell the master worker to do it all over again, and you will record it."

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

If the steel material wants to be combined with the copper clad, it must be pre-treated. It is necessary to use a steel strip surface cleaning machine to derust, degrease, degrease, and roughen the base steel strip.

There is no such machine in the factory today, so it can only be processed manually.

While the workers were processing the base steel, Jiang Yan took Hu Dahai to the place where the copper powder was going to be coated with copper on the base steel.

Copper powder used as copper cladding still has strict requirements. Composite copper powder needs to be classified, proportioned, annealed, and dried, so that the treated copper powder can be used for copper cladding.

After seeing that there were no problems with the two parts, Jiang Yan ordered the workers to start binding.

After the processed steel strip is uncoiled by the uncoiler, it goes through processes such as leveling, guiding, and deviation correction, so that the base steel strip smoothly enters the distributor and powder mill from the uncoiler.The distributor is used to control factors such as the flow rate of the composite copper powder, the uniformity of the distribution, and the thickness of the composite layer.The first-rolled composite strip enters the winder after passing through the steering device.

Jiang Yan took a flashlight and looked at the nozzle where the copper powder was sprayed, and his face changed.

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

As soon as Jiang Yan finished speaking, the rumbling machine stopped.

"Jiang Gong, what's the matter?" Hu Dahai and Qin Ming ran up to Jiang Yan at the same time, asking why they stopped.

"Look, the copper powder is not sprayed evenly. It should be a problem with the air nozzle. Mr. Hu, prepare some tools. I'll take it apart and have a look."

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

Jiang Yan took the tools and started working.After a while, Jiang Yan took out the nozzle, took a closer look, and said to Hu Haihai, "It's the problem with the nozzle. You can see that the nozzle of this nozzle is too big, and the copper powder is not evenly sprayed."

"Jiang Gong, do we need to reset a nozzle?" Hu Dahai immediately asked.

Hearing what Hu Dahai said, Jiang Yan nodded.

Then Jiang Yan said again: "Small problem, Mr. Hu, help me get some paper and pens, and I will draw a new nozzle."

Jiang Yan found a workbench at random, and in less than 5 minutes in front of Hu Dahai and Qin Ming, he drew a drawing of a nozzle.

Jiang Yan put away the drawn drawings and said to Hu Dahai: "Go to Master Sun Deshui and ask him to produce ten such nozzles immediately according to the drawings. I have marked the specific parameters on the drawings."

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

After Hu Dahai got the blueprint and left, Jiang Yan turned to Qin Ming who was standing there.

"Old Qin, help me find some young and strong workers. I need to remove the four nozzles inside. The casing is too heavy, and I can't handle it by myself."

"No problem, Mr. Jiang, I'll find some workers for you right now."

After Qin Ming finished speaking, he called out the names of individual workers in front of Jiang Yan. When these people came in front of Jiang Yan, Jiang Yan realized that the workers Qin Ming arranged for him were really Kongwuli.
