affecting the quality of tungsten carbide rolls?

The quality standard of WC roller is: material porosity, WC grain size, total carbon and free carbon content, density, hardness, magnetic saturation strength, coercive force, bending strength, impurity content and so on.  In addition, the machining accuracy and surface roughness of roller are also considered.  

Each index can reflect the quality and performance of the roll.  The main influencing factors are as follows: the dispersion, particle size and particle size distribution of WC powder and Co powder, total carbon, free carbon, oxygen, iron content, etc.  The type and quantity of rubber used for pressing, the temperature and time of degumming, the temperature, time and atmosphere of sintering, etc.  In addition, the machining accuracy of roller and the quality of diamond grinding wheel affect the quality of roller.  Our company has passed the ISO9001 international quality assurance system certification, can provide users with high quality, stable cemented carbide products.  

Tungsten carbide rolls have been widely used in various fields of metal plastic processing.  Tungsten carbide roller is suitable for non-ferrous metal, steel, hot rolled wire, pipe, cold rolled foil strip, rebar and so on.  Zhuzhou Jinxin can produce more specifications of tungsten carbide roller, accept to plan customized, processing and production.
