各工业部门的用户都要求钢铁企业提供高质量厚板,因此生产厂必须寻找提高厚板质量的新途径。改进轧制工艺,如研究压下比的重新分配,是近年来提高厚板生产质量的主要研究方向。苏联进行的变形分配对厚度宽度差影响的研究,取得了很好的效果。其结论是,在粗轧机架轧制时,纵轧道次最少,横轧道次最多,可以明显减少厚板宽度差。改造厚板轧机设备,有利于完善轧制制度。但与其他轧机不同,厚板轧机一般不进行综合改造,因为这样的改造投资太大。对 Users in all industrial sectors require steelmakers to provide high quality slabs, so manufacturers must look for new ways to increase their quality. Improve the rolling process, such as the study of the redistribution of reduction ratio, is to improve the quality of plate production in recent years, the main research direction. The effect of deformation distribution on thickness width difference in the Soviet Union has achieved good results. The conclusion is that in the roughing stand rolling, the least number of vertical pass, cross-pass the most, can significantly reduce the thickness difference. Rebuilding plate mill equipment is conducive to improving the rolling system. However, unlike other rolling mills, plate mills generally do not undergo comprehensive rebuilds because of the large investment in such revamping. Correct
