Information

Cemented carbide roll ring refers to a roll made of powder metallurgy with tungsten carbide and cobalt as materials. There are two types of cemented carbide rolls: integral type and combined type. Superior performance, stable quality, high processing precision, good wear resistance and high impact resistance.
The performance of the cemented carbide roll is related to the content of the binder phase metal and the size of the matrix phase - tungsten carbide particles. Different binder content and corresponding tungsten carbide particle size form different cemented carbides. A series of cemented carbide grades suitable for different flights have been developed. Tungsten carbide accounts for about 70% to 90% of the total composition mass in cemented carbide, and its average particle size is 0.2 to 14 μm. If the content of metal binder is increased or the particle size of tungsten carbide is increased, the hardness of cemented carbide decreases and the toughness increases. The flexural strength of cemented carbide rolls can reach more than 2200 MPa, the impact toughness can reach (4~6)×106 J/m2, and the Rockwell hardness HRA is 78~90.
