Tungsten Carbide Rod Extrusion Affecting Factors

Tungsten Carbide Rod Extrusion Affecting Factors

Tungsten carbide rod extrusion affecting factors includes mixing, carbon, binder, extrusion temperature, extrusion mould and extrusion speed.
1.Mixing. Mixing is a complex process of completing the powder liquidity and dispersion. In this process the binder must be completely mixed with the powder and becomes a perfect powder which has an excellent liquidity property.
2.Carbon. Carbon content plays an important role in the process of tungsten carbide rod extrusion Tungsten carbide is made of WC and Co, other phase may cause adverse affects to the property of the tungsten carbide rod, thus it is a vital problem to control carbon content in the extrusion process. The decarburization and carburization will affect both the density and property of the tungsten carbide rod.
3.Binder. Binder is used for enhance liquidity and maintain the shape of the tungsten carbide rod in the extrusion process. The require for the binder is good wettability and adhesion, no chemical reaction with the powder and high strength.
4.Extrusion temperature. If the extrusion temperature is too high or too low, it will cause the blanks being out of shape, affects its density and strength, and quality of the tungsten carbide rod.
5.Extrusion mould. If the mould is improper, it will cause the density of the rod being uneven. Thus affect the later transformation in sintering.
6.Extrusion speed. The extrusion speed is various from the productive efficiency and easy to operate. Either the speed is too high or too low will affect the density and shape of the tungsten carbide rod.
