Cemented-carbide processing: as a kind of tool material and structural material, cemented-carbide material has played an important role in promoting the development of world industry and the improvement of production efficiency, which makes the efficiency of human development and utilization of nature increase ten times and hundreds of times. Since the 1990s, with the rapid development of mining, metallurgy, construction and other basic industries as well as high-tech industries such as electronics, aerospace, automobile, etc., cemented-carbide tool materials for non cutting processing have been widely used in a wide range of fields, and the amount is increasing. Especially with the development of pressure processing industry, mining industry, construction industry and so on to the high-speed direction, the pressure tools have been widely used, The quality and efficiency requirements of mining tools, construction tools, and various molding molds are constantly improved, and more stringent requirements for tool materials are put forward. At the same time, with the development of metallurgy, machinery, automobile, chemical industry and petrochemical industry, cemented-carbide materials are widely used in these fields because of their excellent properties such as wear resistance, corrosion resistance, high pressure resistance and high temperature resistance. They are made into various structural parts, especially with the development of cold isostatic pressing, extrusion, slurry casting, injection molding and other molding technologies It is processed into extra large, super long, thin and various complex shape parts, such as engine parts, valve components, bearing parts, guide plate, textile machine parts, gate, nozzle, guide plate, centerless grinder support plate, sealing ring, plunger, lining ring, gauge, etc.
