What Will Affect The Quality Of Cemented Carbide Rolls?

Carbide rolls have been used in various fields of metal plastic processing. From non-ferrous metals to steel, from hot-rolled wire rods and pipes to cold-rolled foil strips and rebars, tungsten carbide rolls are used. The wide application of tungsten carbide rolls has led to higher and higher quality requirements for cemented carbide rolls. Do you know what factors affect the quality of cemented carbide rolls?
The quality standards of cemented carbide rolls include: material porosity, WC grain size, total carbon and free carbon content, density, hardness, magnetic saturation strength, coercive force, bending strength, impurity content, etc. In addition, there are machining accuracy and surface roughness of the roll.
The level of each index reflects the quality of the roll and indicates its performance. Factors that affect the quality of rolls are: the dispersion, particle size and particle size distribution of WC powder and Co powder in the mixture, the content of total carbon, free carbon, oxygen, iron, etc.; the type and quantity of glue used for pressing, and the temperature and time of degumming , Sintering temperature, time and atmosphere, etc. In addition, the precision of the grinding machine for processing the roll and the quality of the diamond grinding wheel all affect the quality of the roll.
