In the entire rolling mill market, used rolling mills occupy a large share, because its price is relatively low, which just meets the needs of those customers who are unwilling to invest more to purchase new rolling mill equipment. However, second-hand rolling mills cannot be purchased blindly, and a slight inattention will threaten their own interests.

Due to the rolling force of the rolling mill, its adjustment of the screw nut up and down will be affected to varying degrees, and one of the possible consequences is the automatic unscrewing of the screw in the rolling mill. Under normal circumstances, the automatic unscrewing of the screw is mainly produced on the blooming mill and the strip rough rolling mill.

It has been proved by practice that environmental factors are also included in many factors affecting the daily work efficiency of the rolling mill, mainly the humidity and temperature of the environment. Therefore, in order to improve the working efficiency of the rolling mill, the narrow outlet of the heating furnace has strict requirements on humidity. In the case of no tapping, closing the furnace door can reduce air consumption and heat transfer, and reduce the cost of coal or gas.
In high-speed wire rod mill plant, the more commonly used production equipment is the high-wire finishing mill. As an important part of the equipment, the roll set must maintain good lubricity, otherwise, the normal operation of the equipment belonging to the rolling mill machine will be adversely affected, which will reduce the manufacturer’s production ability.

The importance of the rolling mill roller table in the rolling mill cannot be replaced, and the reasonable arrangement of the roller table can greatly save the rolling time of the steel rolling production line and the labor intensity of the workers. For example, the working roller table arranged before and after the working stand of the rolling mill and the roller tables arranged before and after the blooming mill are all working roller tables. The reclaiming device is the key equipment for reclaiming the billet from the feeding platform to the feeding roller table.

In the rolling work, on the one hand, we must pay attention to controlling the running status of the rolling mill machine, and on the other hand, we must ensure that the hydraulic piping system is operating normally. Therefore, in order to meet the production requirements, the rolling mill piping subsystem mainly includes auxiliary hydraulic pressure, servo hydraulic pressure, thin oil lubrication of gears, thin oil lubrication of conveying rollers and curved roller transmissions, thin oil lubrication of oil film bearings, high pressure descaling water, dry oil lubrication, and equipment cooling water.
