摘要
用金相、低倍和化学检验方法,对3.5mm厚的热轧卷板严重纵裂和折皱废品进行检验分析,认为纵裂和折皱废品是由于板坯加热过程中局部过烧所致,并提出整改措施。
It was regarded that local over-burning results in split crack and pinch during the slab heating by metallographic, macro and chemical analysis to examine the split crack and pinch on 3.5mm hot-rolled strip rejection. And the countermeasures were put forward.
