Abstract

Abstract

The hot grind schedule of work roll in hot strip mills includes the cooling time waiting for grinding after rolling and corresponding compensatory contour. On the basis of analysis of varying rules of work roll thermal field and thermal contour during rolling and after rolling, the hot grind schedule is establish-ed. The optimum cooling time of work roll after rolling is about two hours and its compensatory contour varies with the latency time after grinding.
