摘　　要：随着国内中厚板生产线数量的不断增加,板材市场竞争日益激烈,客户对中厚板表面质量也提出了越来越高的要求。在中厚板生产中,矫直辊产生的钢板表面压印严重影响着产品表面质量。针对压印形成原因进行深入分析,并结合现场修磨辊系经验,通过对不同规格钢板采用不同的卡量点、减少热钢板在矫直机辊系的停留时间、辊系外冷水增加喷吹装置以及快速排空冷却水管内冷却水等措施,显著降低了矫直辊压印的产生几率,改善了钢板的表面质量,同时提高了经济效益。With the increasing number of the medium and heavy plate production lines at home,the steel plate market competition gradually becomes more fierce,the customers raise higher requirements on the surface quality of medium and heavy plate.In the process of the steel plate production,the leveling roll's imprint on plate surface severely affects the surface quality of the finish products.The formation causes of the imprint are analyzed in depth and in combination with the grinding experiences of roll sets at site,various measures are taken,i.e.,planning different measuring points for steel plate of different sizes,reducing the holding time of hot plate in the levelling roll set,adding blowing-off device for the external water cooling of the levelling roll set,rapidly evacuating the cooling water inside the cooling water pipe,which significantly reduces the occurence probability of the levelling roll's imprints,improves the surface quality of steel plate and economic benefits.
