Do you know what you need to pay attention to in the installation of carbide rolls?

Carbide roll has good wear resistance, high temperature red hardness, heat resistance fatigue and high strength, has been widely used in the production of rod, wire, rebar and seamless steel pipe, greatly improving the effective operation rate of rolling mill. According to the different working environment of each frame roll, various grades of cemented carbide roll rings have been developed. Carbide roll has two kinds of integrated and combined. Superior performance, stable quality, high processing precision, good wear resistance and high impact resistance. In use, we need to pay attention to the following matters during the installation process:

1. Roll matching: the same roll warp difference on the same frame should be 0, not more than plus or minus 0.05mm

2. Before loading the roller, the roller ring and cone should be placed at a constant temperature of 25-30 degrees Celsius to keep warm, while pouring hot water on the roller, or idling for 20 minutes to preheat it.

3. The insertion and assembly of the roller ring are carried out in strict accordance with the precision required by the design process. The roller ring and the frame roller shaft and the cone sleeve are required to be suitable, and can not be too tight or too loose

4. Before loading the machine, check whether the roller ring meets the requirements, and the assembly surface of the roller ring, cone sleeve and shaft should be carefully scrubbed. It is forbidden to hit the roller ring with a hammer or other hard objects when loading the machine.

With the needs of economic development, many iron and steel enterprises in pursuit of development, constantly update their own equipment and technology, but also continuously improve the rolling speed of the mill, reduce the number of shutdowns of the mill, and further improve the effective operation rate of the mill. The use of carbide rolls with higher rolling life is one of the important means to achieve the goal. So choose a production of high-quality carbide roller ring company is particularly important, Zhuzhou Jinxin is a one-stop carbide production customization service provider, focusing on high-quality carbide materials research and development and production, a complete range of molds, a large inventory of conventional products, support to the drawing to sample customization, fast delivery time, strong supply ability.
