Flat head tungsten steel stud for mine high pressure roller
High pressure roller press has the advantages of high crushing efficiency, low energy consumption and high material yield. The performance of the pins of the cemented carbide roller press determines the operation of the roller press. The good operation of roller press needs the guarantee of high quality cemented carbide stud. Our company strictly controls the process, good wear resistance, high bending strength, supply various shapes of tungsten carbide steel column.
- Standard
Product Introduction:
As the core parts of the roller press, the hard alloy stud provides high wear resistance and high compressive strength for the roller press, which can meet the requirements of different working conditions. The hard alloy stud used in roller press is suitable for crushing all kinds of rock in metal ore, which can meet the operation requirements such as iron ore and has high working efficiency.
Product Features:
1. The corner adopts arc chamfering transition to avoid local damage in the process of production, transportation, installation and use.
2. Sintering by overpressure sintering, the product has good density and high strength.
3. Using special technology, eliminate the surface stress of the product after processing, and increase the surface hardness.
