What is the automatic stop of six-high rolling mill?

When the material is cut off or the rolling conditions meet the requirements of the equipment, the equipment has designed a protection program to quickly reduce the tension and stop the machine. There are many conditions to satisfy this illusion. For example, the tension is misjudged because the coil is too loose, and the tension is lost when it is tightened instantly. There is something wrong with the winding diameter counter, and the tension is constant, but the winding diameter does not increase and the torque does not increase. Because of the torque mismatch between the front and rear coilers and the main motor, it finally slipped. The work roll is too bright and the rolling process design is unreasonable, resulting in a negative forward slip value. If the equipment thinks that the belt loses tension and breaks, it will be automatically regarded as broken belt. There may be other reasons, specific analysis of specific problems.
