The Use and Maintenance of Semi-Steel Rollers on Steel Rolling Machines
Steel rolling machines are widely used in processes of steel production, such as rolling of hot-rolled steel products, cold-rolled steel products, and galvanized steel products. Usually, steel rolling machines are equipped with semi-steel rollers, which are able to work efficiently and cost-effectively. This article will discuss the usage and maintenance of semi-steel rollers on steel rolling machines.
When using semi-steel rollers to roll steel products, the clearance between the rollers should be adjusted correctly to ensure that the steel products can be rolled evenly and smoothly. Generally, if the clearance between the rollers is too large, there will be waves or depressions on the steel products’ surface. In order to adjust the clearance, the pressure between the arc blocks of the semi-steel rollers can be adjusted to have the required clearance. But if the clearance is too small, the steel product may be deformed due to the pressure, and in this case, the clearance should be increased slightly.
If the steel rolling machine is equipped with multiple rollers, the rotation speed of each roller should be adjusted so that the rollers can function synchronously. Due to the imbalance of speed, the steel products may deviate from the required shape when rolling, so the speed should be adjusted accordingly.
Besides, it is important to regularly inspect and maintain the semi-steel rollers used on steel rolling machines in order to ensure normal operation and prolong their service life. It is necessary to check the surface of the rollers for any wear and/or damage, and replace the worn or damaged rollers in time. Moreover, the lubrication of the semi-steel rollers should be maintained to increase their lubricity, so that the steel products can be rolled with minimum friction and heat.
Last but not least, the wear and tear of the semi-steel rollers should be monitored in time. If the wear and tear exceeds the preset range, the rollers should be replaced. The wear and tear of the semi-steel rollers will affect its wear resistance and surface finish, thus affecting the rollability of the steel products.
In conclusion, semi-steel rollers are important components of steel rolling machines and require timely maintenance and inspection in order to ensure the quality of the rolled steel products. The use and maintenance of semi-steel rollers can help lower production costs and improve the quality of steel rolling machines.
