Speaking of cemented carbide, since it was created by German scientists in the early 1920s, it has been on the market with the title of "widia" (similar to diamond), and it was the first to manufacture tungsten wire drawing dies for industrial application, replacing the price at that time. Expensive diamond drawing die, the editor of the cemented carbide strip manufacturer below invites us to continue to discuss, please look down.
Although my country's cemented carbide started late, it has developed rapidly. At present, cemented carbide molds have basically been serialized and standardized. Judging from the development situation in recent years, the theory of research and design of cemented carbide molds in my country has been deeper and more scientific, and the application is more common.
In recent years, the new research hotspots are fine-grained, ultra-fine-grained, and even nanocrystalline cemented carbide and gradient cemented carbide. Gradient cemented carbide also has composition gradient, structural gradient, etc. In addition, there are also methods of metal melt infiltration to produce gradient cemented carbide, such as gradient cemented carbide top hammer.
Fine-grained and ultra-fine-grained cemented carbides are also on the market. For example, the fine-grained YGS wire drawing die is 3 times that of the ordinary wire drawing die when drawing <φlmm steel wire.
In addition, there are inlaid casting and inlaid cemented carbide hot working dies, which have achieved good results in tube rolling and wire rod rolling.
