Abstract:

Against the problem that the kiss between working roll ends ocurs easily and harmful contact between working roll and back-up roll in the skin rolling of thin-narrow strip, taking the 1220 temp mill of Thin Strip Co.Ltd of BaoSteel as subject investigated,on the basis of large quantity field experiments and theoretical study, a set of mathematic model about roll shape against the skin rolling of thin-narrow strip was put forward that was aimed at controlling the kiss between roller ends,conceling harmful contact zone and asuring mechanics characteristics and shape of strip quality. In addition, a set of modified scheme of roll shape of strip was put forward,the effectiveness was proved by comparison experiments of canonical specification products.Recently, this roll shape has been used as process specification on field and has obtained better effectiveness and has created greater economic returns.

Key words: kiss, mechanics characteristic, roll shape of strip, roll shape
