摘要
针对高强钢、超高强钢的轧制生产需求,通过合金成分设计和制造工艺开发,研制出轧制高强钢用新型冷轧工作辊,工作层的耐磨性能以及辊体的强韧性得到显著改善。现场使用结果表明:单周期平均轧制吨位提高了约40%,单次下机磨削量降低了约7%,使用性能优于进口的同类型冷轧工作辊。新型冷轧工作辊适用于汽车用高强钢的轧制生产,硅钢、不锈钢及其他难轧板材等也有广泛的应用前景。
In order to meet the needs of rolling high-strength steel and ultra-high-strength steel,a new type of cold work roll was developed by the alloy composition design and manufacturing process optimization.Wear resistance of the working layer and strength-toughness of the roll body have been significantly improved.The application results at the work site show that the average rolling tonnage in a single-cycle increased by about 40%,and the grinding depth after serving was reduced by about 7%.Its performance is better than that of the imported cold work roll of the same type.The new work roll can meet the demand of rolling high strength automobile steel,and it also has a broad application prospect in cold rolling of silicon steel,stainless steel and other steel sheets which are difficult to be rolled.
