1. Removing Oxides and Impurities from Hot Metal
The steel mill production process generates a large amount of hot metal oxides and impurities. If these oxides and impurities are not removed promptly, they will interfere with the rolling process, resulting in uneven rolling or the formation of scale on the surface. Therefore, before rolling, the hot metal oxides and impurities should be thoroughly removed.
2. Controlling the Rolling Temperature
Controlling the rolling temperature of steel is critical. If the rolling temperature is too high, it can easily lead to uneven surface quality or unstable internal structure. If the rolling temperature is too low, the rolling effect will be affected. Therefore, the rolling temperature should be well controlled during the rolling process.
3. Keeping the Rollers Clean
The rollers are the most important tools in the steel rolling process. If impurities or rough surfaces on the rollers are present, they will affect the quality and surface finish of the steel. Therefore, the rollers should be kept clean, regularly inspected for damage, and maintained promptly.
4. Monitoring Rolling Parameters
Rolling parameters refer to parameters such as force, speed, and roll gap during the rolling process. Mastering these parameters can ensure the rolling quality and surface finish. Therefore, during the rolling process, the rolling parameters should be monitored frequently and adjusted in time.
