Sintering Technology of Tungsten Carbide Ultrafine Cemented Carbide

Cemented carbide is mainly used in cutting tools, mining tools, molds and high-pressure and high-temperature rejection cavities, among which cutting tools and mining tools account for 33% and 25% of cemented carbide applications. Among cutting tools, cemented carbide is mainly used as tool materials, such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and difficult to machine The cutting process is mainly realized by machine tools. In terms of mining tools, cemented carbide is mainly used as rock drilling tools, mining tools, and drilling tools, and plays an important role in minerals, oil exploration, infrastructure construction and so on.

Superfine cemented carbide sintering technology

The performance of cemented carbide is inseparable from its manufacturing process. Of course, the performance of raw materials is the fundamental of the performance of the finished product, but not only that, the forming, sintering process and equipment factors also occupy an important position. Among the many manufacturing processes, the most important process is sintering. This special process will directly determine the performance changes of the product. Appropriate sintering process parameters are as important as sintering equipment. In industrial production, the commonly used sintering methods include hydrogen sintering, vacuum sintering and low-pressure sintering.
