摘　　要：文章对HN700 mm×300 mm型钢轧制缺陷产生的原因进行了分析,并提出了消除轧制缺陷的方法。通过减少轧制缺陷,提高了HN700 mm×300 mm型钢的成材率,并将消除HN700 mm×300 mm型钢轧制缺陷的经验运用到其它规格H型钢的生产中。In this paper, the causes of rolling defects in HN700 mm × 300 mm H - beam are analyzed, and the meth-ods of eliminating rolling defects are put forward. By reducing the rolling defects, the yield of HN700 mm × 300 mm H - beam is improved, and the experience of eliminating rolling defects in HN700 mm × 300 mm H - beam is applied to the H -beam production of other specifications.
