Lao Wang and Lao Li invited the three smelting masters, named Zhou Jianfeng, Chen Gaoliang and Yu Deli, among which Zhou Jianfeng is the oldest and has the richest smelting experience and the best technology.

Although the process of smelting special superconducting materials is relatively complicated, Shi Lei and others have already developed the formula and technology for smelting, and may not be able to be smelted successfully at one time.

Before this, Shi Lei had prepared a lot of materials and had made plans to fail many times.

After all, during the smelting process, not only the formula ratio of the material cannot be made in the slightest error, but even the amount of materials placed, the time of various materials placed, and the heat of the material placed in the smelting process, otherwise, the impact on the performance of the material will be very huge.

As Shi Lei turned on the switch of the smelting equipment, the smelting equipment began to operate. At this time, the three masters did not put materials into the equipment, but waited for the machine to preheat. This smelting equipment is a new equipment, not those old equipment, and must be preheated.

After waiting for half an hour, the temperature inside the equipment was already very high, which means that the preheating of the equipment has been completed.

So the three masters began to put in a large amount of pure copper according to the formulation process requirements of the special superconducting materials provided by Shi Lei.

Solid copper made of pure copper was successively put into the smelting equipment. After a certain amount of pure copper was put in, the three masters also stopped at this time and began to wait for the pure copper to melt.

Soon, pure copper turned into copper water at the high temperature of the smelting equipment, and a little impurities floated on the copper water.

Since this smelting equipment is a small equipment and is not an intelligent equipment, many processes still require manual operation by the master, such as salvage of impurities on these copper water.

So the three masters started to take action together, fishing out all the impurities floating on the copper water. When the temperature of the copper water meets the requirements of the smelting process, they start to put another material...

Time flies so fast, and in a blink of an eye, a few hours have passed, and the special superconducting materials that Shi Lei and his Stone Machinery Factory smelted for the first time are about to be released.

Shi Lei, Lao Wang, Lao Li and three smelting masters were all staring at the thermometer of the smelting equipment at this time, and waiting for the furnace of superconducting materials to be smelted this time to be released.

Not long after, the thermometer pointer on the smelting equipment finally pointed to the temperature required in the smelting process. Yu Deli immediately stepped forward and opened the discharge port of the smelting equipment. He saw that the red copper alloy water slowly left along the discharge port and entered the mold that Shi Lei and the others had already prepared.

This smelting equipment is just a small smelting equipment, so it is not much smelting each time. It can only accommodate about two tons of copper water within the interior. This time, Shi Lei and the others only put about 1.3 tons of copper water. Adding other materials, the copper alloy materials that Shi Lei and the others smelted this time were only about 1.5 tons.

There are not many materials smelted this time, less than 1.5 tons, but Shi Lei and the others are still looking forward to it. This is their first time to smel special superconducting alloys by Stone Machinery.

Soon, the copper alloy water in the smelting equipment was placed in rectangular molds for cooling, and it took a certain amount of time to cool.

It’s not that Shi Lei and the others don’t want to use water to cool these alloy materials, but that they have been clearly stated in the smelting process. They cannot use any cooling methods to cool down, and they can only wait for the natural cooling of the materials.

So Shi Lei and the others waited for more than an hour. Finally, when they were almost ready, Shi Lei, Lao Wang and Li and three masters came to the side of these special superconducting materials that had basically been cooled down at this time.

When he came to these superconducting materials, Shi Lei found that the superconducting materials poured in the mold turned orange at this time, which was very different from ordinary copper materials. Of course, it was also very different from the superconducting materials currently available on the market, and looked very beautiful.

"Master Zhou!Master Yu!Master Chen!How about it, does the colors of these materials meet the requirements of formula technology?" As a non-professional, Shi Lei certainly does not understand this very well.

Even if he was given a smelting formula and smelting process, Shi Lei couldn't understand it, not to mention that there were professionals such as Zhou Jianfeng on the spot, Shi Lei didn't have to think about it himself, just ask the professionals directly.

"Boss! It doesn't matter much when it comes to the smelting process, but just looking at the color doesn't mean anything." As he said that, Master Zhou Jianfeng picked up an iron rod with his hand and knocked it on the material.

When Zhou Jianfeng and others heard the crisp sound of copper alloy, their faces looked a little happy.

At this time, Zhou Jianfeng and others' inspection was not over yet. They picked up a mold and poured out the copper alloy inside, and then looked at it carefully.

After a long time, Zhou Jianfeng stood up and said to Shi Lei: "Boss! Judging from the current color and sound of this material, although we have not been successful in smelting this superconducting material this time, it is already very close to the materials in the formula. According to the current situation, smelting one or two furnaces will be almost successful.

Of course, it is not enough to rely solely on our experience. After all, people sometimes make mistakes in their feelings, and the specific one depends on the results of equipment detection."

In fact, it doesn’t take Master Zhou and the others to say that Shi Lei already knew the result at this time, because just when Master Zhou and others checked this material, Shi Lei had already turned on the industrial overlord system to identify the comprehensive performance of this material. The identification results were not much different from what Master Zhou and others said.

According to the results of the system identification, the comprehensive performance of the previous superconducting material is 2.0, not 2.1, which means that this material has reached the standard of generally low-performance special superconducting materials in this era, but there is still a difference of 0.1 performance point with the superconducting materials in Shi Lei and his formulas. In other words, their smelting has actually failed this time!

However, Shi Lei did not say this. After all, he didn't want others to know about his systematic things. At this time, Shi Lei was also very impressed by Master Zhou and the others. After all, the master is a master, and their experience and skills are indeed not comparable to ordinary smelting masters. Just relying on his own feelings, he almost told whether this material was smelting successfully.

Master Zhou and others picked up this material and came to the front of the testing equipment, turned on the equipment and put the material in it, waiting for the equipment to test results.
