Abstract：Since the shape quality standards of silicon steel strip is getting stricter, the requirement for the hot rolling strip shape in cold rolling process is higher, and the edge drop control is a key indicator of good shape for silicon steel strip. To deal with the problem of the severe edge drop occurring in the same width campaign of CSP and the low yield, a work roll technology with a taper profile at one end is developed. The shape control characteristic of CSP using work roll contour technologies is analyzed, and the taper roll is used in the downstream mill. The taper roll edge drop control theory and the roll design methods of the main parameters are introduced. The results showed that the application of the taper roll has reduced the edge drop considerably.
