摘　　要：文章主要阐述了包钢轨梁轧钢厂2#万能生产线H型钢矫直工艺参数优化,通过修改矫直辊辊圈的装配宽度、重新制定矫直机矫直参数、在保证平直度的前提下减轻矫直压力、修改矫直辊R角圆弧等措施,解决了H型钢矫直后出现的矫裂缺陷,提高了产品质量。This paper mainly expounds the optimization of H- beam straightening process parameters sal production line in Rail and Beam Plant of Baotou Steel. By modifying the assembled width of straightening roller ring,redesigning the straightening parameters of straightening machine, reducing the straightening pressure and modifying the ra-dius of R angle of straightening roll on the premise of ensuring the flatness to solve the straightening crack defects of H- beam after straightening and improve the quality of products.
