The speed at which the rolling mill machine is started during operation has a very important effect on the efficient work of the rolling mill. If the starting speed of the rolling mill machine is slow when it is ready for operation, it means that there is a significant deficiency in the performance of the rolling mill equipment, which will affect the working efficiency of the rolling mill. The force between the billet or rolled product and the roll cannot reach good condition.
The rolled piece cannot be fully rolled in the rolling mill. Under this condition, the power consumption of the rolling mill machine is several times higher than usual. If it happens often, the speed of the rolling mill cannot be effectively started, the efficiency of the billet or rolled product will become lower and lower. For steel rolling mill equipment, if it cannot be started quickly and overloaded, the billet rolling speed will be too slow. Here, let me analyze the reasons and solutions for the slow startup speed.
Before starting the rolling mill machine, it is necessary to verify the power of the equipment motor, rolling speed, product specifications, hole technology, etc., ensuring that the amount of billet retransmission does not exceed the bearing capacity of the rolling mill equipment, otherwise the startup speed of the equipment will slow down. We also need to check the rolling mill bearings to see if the bearings are adequately lubricated. If the lubrication is not sufficient, the rolling mill machine's start-up will also slow down or even malfunction.
