What are the problems of hot sleeve of powder metallurgy gear parts?

With the continuous development of national industrial technology, the traditional casting process of powder metallurgy has been unable to meet the needs of modern industry, so now the parts and components used in many fields need to be produced by high-tech means, however, powder metallurgy is this high-tech process. So what are the problems of powder metallurgy wheel heat jacket? Let's take a look at zhongwei's precision knitting.

The questions are as follows:

1. Firing furnace (mesh belt furnace) Firing, ammonia protection, no matter iron or copper base, first mix with powder and then press, then burn the whole shape and finally fill oil.

2. It can be used for carbonitriding, nitrocarburizing, induction quenching and other heat treatment.

3. Try carbonitriding at about 850 ℃ for 4 hours. The amount of kerosene should be large. The products to be heat treated should not be soaked in oil first.

4. It can be carbonitriding. Minxin has tested the carbonitriding of American parts.

5. Firing furnace (mesh belt furnace) Firing, ammonia protection, no matter iron or copper base, first mix with powder and then press, then burn the whole shape and finally fill oil.

To sum up, it is the hot sleeve problem of powder metallurgy wheel parts. I hope this article can help you. If you need more information about powder metallurgy, please pay attention to the official website of zhongwei Precision.
