The Influencing Factors and Improvement Measures of Roll Changing in Cold Rolling Mill
Aiming at the problem of too long roll change time of an acid tandem mill,this paper analyzed the roll change device and roll change control time sequence of the production line,combined with the actual situation of the site to analyze the main reasons affecting the roll change time of the mill,including cumbersome roll change control time sequence steps,slow operation of the mill equipment,poor signal detection accuracy,etc.By modifying the roll change control,adjusting the equipment speed,optimizing the control program and optimizing the detection method,the roll change time is reduced by 33％and the operation rate of the production line is increased.
