Study On Reducing The Stability Of The UCM Cold Rolling Mill Production

In this paper, the main content in order to reduce rolling FGC strip break times and improve the acid at the end of the frame roll roughness uniformity of two aspects,the former through the electrical secondary program FGC transition table of rolling optimization and the shear in the primary and secondary program timing in advance as well as the specific steel grade do automatic lifting roll gap function, finally, by using the method of statistics will be easy to the types of steel strip break in anticipation, increase the risk of reasonable transition is expected to reduce the fault belt. The latter using minitab software, first of all influence factors were analyzed, and the grade of FMEA, filtering factor, after the DOE design experiments, finds out the factors most affected, using the corresponding ratio of surface to find reasonable parameters for matting, will eventually lock parameters for the transverse velocity changed to 45 mm/min, electricity power time is changed to 17 us, time is changed to41 us, reach Ra is 3.6 um roll roughness of + /- 0.15 percent of pass is above 80%.
