摘要
介绍了连续热镀锌带钢镀层表面存在的各类常见缺陷,包括锌渣、气刀条痕、划伤、热褶皱、光整羽痕和压印等,并分析了缺陷产生的原因,针对缺陷提出了解决措施。实践表明,热镀锌带钢的表面质量明显改善,O5板合格率达到了90%以上。
Various kinds of common defects on the surface of continuous hot-dip galvanizing steel strips including zinc slag, steaks caused by air knife, scratches, wrinkles in hot condition,pinnate marks due to the finishing process and impressions were introduced while the causes leading to the defects were analyzed. Then countermeasures for dealing with the defects were proposed. The production practice showed that the surface quality of the hot-dip galvanizing steel strips was obviously improved and the qualified rate of O5 steel sheets was over 90%.
