Application Advantages and Disadvantages of Tungsten Carbide Roll Rings in Bar Rolling Mills
Tungsten Carbide Roll Rings are gradually becoming important components of bar rolling mills. The carbide rolls are directly placed on the mandrel and used to press the bars that are heated in the rolling mill to make them deformed in the axial direction and obtain the desired section. Then the bars are promptly cooled and rolled out.
The main advantages of the Tungsten Carbide Roll Rings are as follows. First, the strength of the Roll Rings itself is much higher than that of ordinary high speed steel roll rings, which greatly improves the service life of the roll rings and greatly reduces the probability of failure of the roll rings. Secondly, since the carbide roll rings can be used at a higher temperature than ordinary steel roll rings, and the temperature control range is wider, the temperature of the rollers themselves is more difficult to go beyond the required range. In addition, the use of Carbide Roll Rings can create a processed product with higher dimensional accuracy and surface finish than with ordinary steel roll rings, which means that the final product meets higher quality standards.
However, the use of Tungsten Carbide Roll Rings also has some drawbacks. The cost of Carbide Roll Rings is much higher than that of ordinary steel Roll Rings, which means that the cost of equipment is higher. In addition, due to the different characteristics of the service life of Carbide Rolls, it is necessary to periodically inspect and adjust the Roll Rings, thus causing additional maintenance costs. Third, the use of Tungsten Carbide Roll Rings does not reduce the deformation rate, that is, the occurre
