How to Carry out Daily Maintenance of Rolling Mill?

Rolling mills are widely used in the steel industry. In order to ensure the smooth running of daily work, daily maintenance is particularly important. It should be noted that the daily maintenance of the rolling mills will affect the service life. So how to carry out the daily maintenance of the rolling mill, how to operate?

Every day, the rolling mill is inspected for oil, water and gas leakage and overheating of the machine parts; reducing the loss caused by the illegal operation of the equipment or maintenance, and when lifting the rubber rolls, take necessary maintenance measures at the chain, rope and end of the roll surface.

The automatic thickness control system on the rolling mill is operated strictly in accordance with the rolling mill operating process and operating methods. The gearbox should be cleaned at least once a quarter. When the roll is fed to the extreme position, special attention must be paid to the safe operation of the rolling mill. Care should be taken when performing the rolling mill operation to prevent the hand from being pressed by the steel plate and being fed together with the steel. When using the aircraft hoisting mill for inspection, be careful not to collide with the machine.

In the rolling operation, the personnel of each department should coordinate with each other and listen to the command of the person in charge of the rolling mill production line. In the rolling process, the roller and the raceway are in line contact or repaired line contact, and the radial bearing capacity is large and is suitable for bearing heavy load and impact load. If irregular noise is found, such as the abnormal phenomenon that the roller cannot be touched by the sudden release of the load after the steel bar is interrupted, it should be stopped immediately and checked, and the steel rolling production line can be completely stopped before being repaired. After the main drive of the motor is stopped, the upper and lower rolls can be lifted and lowered. When cleaning, firstly, in the hot state, stop the oil drain screw on the side of the gearbox, and turn the rollover of the roll and the lifting of the upper roll.

After the end of rolling, the finished material should be cleared, and the equipment maintenance and repair work should be done. In order to strengthen the effective management of the equipment, the equipment utilization rate should be improved, and the power supply should be turned off in time.
