Chapter 260, Troubleshooting

"Jiang Gong, you brought everything over to me."

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

"Bring it there, and he will mix it for a while. I will take a good look at it and ask him if there is anything he doesn't know. From now on, the formula will be placed in my lap and you will mix 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 prepare 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 answered them one by one.

He answered.

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

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

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

As the saying goes, a good memory is worse than a bad writing. When Jiang Yan taught Hu Dahai's recipe, he clearly recorded every step of the process.

"Mr. 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, is this the director of the production workshop, Qin Ming, 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, Dong glanced at him consciously.

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

Hu Dahai followed him and said, "Jiang Gong, his name sounds familiar! It's the same as the name of Thunderbolt and Fire Qin Mingfen in Water Margin. He was shocked when he 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 hot-tempered. They are known as the go-getters in their factory. Their workshop completes the best production tasks every year."

"Gong Hu complimented me. I like Gong Jiang, but he doesn't like Qin Ming." Qin Ming said and stretched out his leg by mistake to Jiang Yan.

Seeing Qin Ming stretching out his leg, Jiang Yan grabbed his leg and said, "My dear Director Qin, he said no to Jiang Yan."

"I don't want to call him Director Qin. Just call him Lao Qin like Mr. Hu."

After saying that, he smiled heartily, looking so bold and bold.

"Okay, Lao Qin, I need to make a copper clad laminate tomorrow. I'll arrange something for you."

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, and we will use that batch of molten steel to coat the copper steel. He is on his way.

arrange."

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

"That's very true." Jiang Yan looked at his back and said.

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

Jiang Yan blushed when he saw the copper-clad steel coming out. His thinking was too simple. Looking at the situation, it was not a matter of chemical agents, and it should be 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 plates refer to the synthesis of two metals by rolling metal copper powder and steel plates.

It is an integrated bi-metal plate product.

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 realize 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.

Processing. The thickness of the composite plate is not limited. The combination of metal powder rolled copper-clad steel belongs to 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 also a method suitable for the country's production of copper-clad steel.

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

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

The combination of steel and copper cladding requires preliminary treatment. It is necessary to use a steel strip surface cleaning machine to remove rust, degreasing, degreasing and texturing the base steel strip.

If there is no such machine outside the factory, then manual processing can be used.

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.

Are there still strict requirements for copper powder for copper cladding? Composite copper powder needs to be graded, 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 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 rolling mill from the uncoiler. Use the distributor to adjust the flow rate of the composite copper powder and ensure the uniformity of the distribution.

The thickness of the composite layer and other factors are controlled. The rough-rolled composite strip enters the winder after passing through the steering device.

Jiang Yan took the 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 rumbling machine stopped.

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

"I think if the copper powder is sprayed unevenly, it could be a problem with the jet nozzle. Worker Hu prepared some tools and he took them apart to take a look."

Hearing Jiang Yan's request for tools, Qin Ming next to him quickly asked the workers to bring over a complete set of disassembly tools.

Jiang Yan took the tool and started working. After a while, Jiang Yan took out the nozzle, looked at it carefully, and said to Hu Dahai: "Is there a problem with the nozzle? I think the nozzle of such a nozzle is too big, and the copper powder is sprayed unevenly.

.”

"Gong Jiang, can we please reset a nozzle?" Hu Dahai asked immediately.

After hearing what Hu Dahai said, Jiang Yan nodded.

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

Jiang Yan randomly 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 turned to Hu Dahai and said, "I'm going to find Master Sun Deshui and ask him to immediately produce ten such nozzles according to the drawings. He has already 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, and spoke.

"Old Qin, help him find some young and strong workers. He needs to remove the four nozzles inside. The casing is too heavy and he can't do it alone."

"No problem, Mr. Jiang, he will find some workers for me."

After Qin Ming finished speaking, he called out the names of individual workers in front of Jiang Yan. Only when Zhai and others came to Jiang Yan did Jiang Yan realize that the workers Qin Ming arranged for him were indeed very powerful.
