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 of HN700 mm × 300 mm section steel are analyzed and the methods to eliminate the rolling defects are proposed. By reducing the rolling defects, the yield of HN700 mm × 300 mm section steel is improved and the experience of eliminating rolling defects of HN700 mm × 300 mm section steel is applied to the production of other H sections.
