The Application of Carbide Roller in High Speed Wire Production
Carbide roll rings are widely used in high-speed rolling mills. In high-speed wire rod mills, the rolling forces, rolling moments and wear on roll rings on different stands are different, and accordingly different carbide grades must be used. Normally, the rolling load of the front stand (such as the intermediate rolling and pre-finishing stands) is relatively large. The roll ring is required to have good toughness and strength, and a brand with a high content of bonding phase must be chosen; and the subsequent frame (such as the finishing rolling frame, the reduced diameter frame RSM, and the dual-module TMB frame) has a long steel passing time and requires The roller ring has better wear resistance, and it is necessary to choose a brand with a low binder content: especially the finished product and the front frame of the finished product. The roller ring has a direct impact on the surface quality and tolerance of the finished wire, compared with the previous frames It is more necessary to change rolls and grooves frequently. Usually, the number of replacements is 2-4 times that of the first few stands. Its wear resistance often plays a decisive role in improving the efficiency of the entire rolling mill.
Carbide composite roll ring is used in the middle rolling stand of the high-speed rolling mill, replacing the traditional cast iron roll, which greatly improves the groove life of the middle rolling stand by 10-20 times, and greatly reduces the downtime of the high-speed rolling mill , While improving the utilization rate of the rolling mill, the working state of the subsequent cemented carbide roll ring is greatly improved, the service life of the cemented carbide roll ring is extended, and the quality of the final product of the wire rod is improved.
