Description
technical field [0001] The invention relates to the field of hard alloy and its preparation method, in particular to an ultra-fine-grained hard alloy rod and its preparation equipment. Background technique [0002] Cemented carbide is mainly used as industrial cutting tools, wear-resistant parts, precision parts, etc. According to different workpieces and working environments, different types of cemented carbide are selected. The mechanical properties of cemented carbide have a lot to do with its grain size. It is believed that the smaller the grain size, the higher its mechanical strength, so ultra-fine-grained cemented carbide is the mainstream direction of development at present. This project mainly develops a kind of ultra-fine-grained cemented carbide. Cemented carbide rods are mostly tungsten steel round rods, because of their high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc. Excellent performance, widely used in ...
