HPGR Hard Alloy Pin Sintering Technology

The key to improve the quality of HPGR Carbide Button is to adjust the precision of the mold, control the loose ratio of tungsten carbide powder loading, accurately control the residual white edge of product molding, remove the gas in the process of pressing products, and stabilize the strength of the green compact.

Tic is added in the sintering process of the cemented carbide, so that the stability of the cemented Carbide Pin stud can be enhanced, and the grain size of the cemented carbide can be restrained. The carbide of titanium rapidly reacts with the residual oxygen and nitrogen in the vacuum during the high-temperature sintering process to form a titanium carbonitride compound, so that the sintering atmosphere of the product in the vacuum furnace can be ensured, and the Hpgr Hard Alloy Pins has a better sintering atmosphere in the sintering furnace. Inhibit the growth of crystal grains of the hard alloy product, ensure the alloying process of the hard alloy and improve the quality stability of the product.
