Original Title: Common Problems and Cause Analysis of Cemented Carbide Pressing Cemented carbide is a kind of alloy material made of hard compound of refractory metal and bonding metal by powder metallurgy process, which has high hardness, wear resistance, good strength and toughness. Because of its unique properties, it is often used to make rock drilling tools, mining tools, drilling tools, measuring tools and so on. It is widely used in petroleum and natural gas,dhd drill bit, chemical industry, engineering machinery, fluid control and other fields. Cemented carbide is a material pressed by powder metallurgy process. Today,overburden drilling systems, Sidi Xiaobian will introduce to you several major problems we often encounter in the pressing process, and briefly analyze the reasons. 1. In the pressing process of cemer elastic tension in the compact. For example, the cobalt content of the mixture is relatively low, the hardness of the carbide is high, rock drilling tools ,Borehole Drill Bits, the powder or particles are finer, the forming agent is too little or unevenly distributed, the mixture is too wet or too dry, the pressing pressure is too large, the single weight is too  of cemented carbide pduce the occurrence of cracks: extending the pressure holding time or pressurizing for many times, reducing the pressure and unit weight, improving the mold design and properly increasing the mold thickness, speeding up the demoulding speed, increasing the forming agent,mining dth bit, and improving the apparent density of the material. The whole production process of cemented carbide is very critical. Xidi Technology Co., Ltd. specializes in cemented carbide production for 15 years.
