Siheyuan starts from a good life

"Jiang Gong, I have brought everything for you."

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

"Bring it here and I'll mix it up later. Take a good look at it and ask me if there's anything you don't know. From now on, I'll put this formula in your hands and let you mix it up."

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 began to get busy preparing the Q/YS.112 electroless copper plating solution. Hu Dahai, who was observing from 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.

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

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

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

"Gong Jiang, come here." Upon hearing Jiang Yan's greeting, Hu Dahai quickly closed his notebook and followed Jiang Yan to the production workshop.

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

Arriving at the production workshop, Hu Dahai took a rough-looking worker and introduced him to Jiang Yan.

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

I was thinking, I don't know why his old man thought that this name is the same as the name of Qin Ming, the Thunderbolt in Water Margin.

Hu Dahai, who was next to him, said: "Jiang Gong, his name sounds familiar! It's the same as the name of Thunderbolt Fire Qin Mingfen in Water Margin. I was shocked when I heard it for the first time. Don't tell me, he Not only do they have similar names, but they also have exactly the same temperament, quite fiery. He is a famous go-getter in our factory. Their workshop completes the best production tasks every year."

"Gong Hu complimented me. Hello, Gong Jiang. 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 Mr. Hu."

After saying that, he smiled heartily. He looked so bold and bold.

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

After hearing what Hu Dahai said, Qin Ming patted his chest and said, "No problem, Mr. Jiang, Mr. Hu." We just made a batch of molten steel. We will use this batch of molten steel to tie copper-coated steel. I will go and arrange it right away. . "

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

"This is really a storm." Jiang Yan looked at his back and said.

"Listen, stop suppressing." At the exit of the steel rolling mill, looking at the copper-clad steel that was still in different shades of copper, Jiang Yan quickly called a stop.

Seeing the copper-clad steel that came out, Jiang Yan understood that his thinking was too simple. It seemed that the situation was not a matter of chemicals, but a problem of pricking.

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

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

Metal powder rolling can achieve either powder-powder composite or powder-plate composite; it can be composited on one side or on both sides; the thickness of the composite layer can be controlled at will. The composite layer does not produce brittle materials and can be completely deformed and processed. The thickness of composite panels is not limited. The metal powder rolled copper-clad steel bonding is a metallurgical atomic bonding.

The copper-clad steel plate products produced by this method have high bonding strength, wide application range and many varieties. It is currently the most suitable method for the country to produce copper-clad steel.

"Lao Hu, tell the master worker to do it again, and you can take notes."

After Jiang Yan finished speaking, he took Hu Dahai to the place where the workers were pre-processing the steel.

If steel is to be combined with copper cladding, it must be pre-processed. A steel strip surface cleaning machine needs to be used to remove rust, degreasing, degreasing and texturing the base steel strip.

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

While the workers were processing the base steel, Jiang Yan took Hu Dahai to where the copper powder was prepared to coat the base steel.

Copper powder as a copper cladding still has strict requirements. The composite copper powder needs to be graded, proportioned, annealed, and dried so that the processed copper powder can be used for copper cladding.

After seeing that there were no problems with these two pieces, Jiang Yan ordered the workers to start making them.

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 can smoothly enter the distributor and powder mill from the uncoiler. Use a distributor to control the flow rate, distribution uniformity, composite layer thickness and other factors of the composite copper powder. The newly rolled composite strip enters the winder after passing through the steering device.

Jiang Yan took a flashlight and looked at the nozzle that sprayed copper powder, and his expression changed.

"Pause feeding." Jiang Yan turned around and shouted.

As soon as Jiang Yan finished speaking, the machine that was still rumbling at work stopped.

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

"Look, the copper powder is sprayed unevenly. It should be a problem with the jet nozzle. Mr. Hu, prepare some tools. I'll take it apart and take a look."

Hearing Jiang Yan's request for tools, Qin Ming, who was standing next to him, quickly 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 Dahai: "It's the problem with the nozzle. You see, the nozzle of this nozzle is too large, and the copper powder is sprayed unevenly."

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

Jiang Yan nodded after hearing Hu Dahai's words.

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

Jiang Yan found a workbench and drew a drawing of a nozzle in less than five minutes in front of Hu Dahai and Qin Ming.

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

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

After Hu Dahai got the drawings 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 do it alone."

"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 discovered that the workers Qin Ming arranged for him were really powerful.
