冷轧Q195L带钢表面翘皮缺陷分析
Analysis of Skin Rising on Cold-rolled Q195L Strip Steel Surface
-
摘要: 通过宏观检验、化学成分分析、金相检验和能谱分析等手段对冷轧Q195L带钢表面翘皮缺陷进行分析。结果表明: 钢中存在的多种非金属夹杂物、氧化铁皮和保护渣是引起带钢翘皮的主要原因。Abstract: The skin rising flaws on the surface of the cold-rolled Q195L strip steel were analyzed by means of macroscopic examination,chemical composition analysis,metallographic examination and energy spectrum analysis. The results showed that many kinds of non-metallic inclusions and iron scale and slag in the steel were the main reasons led to the skin rising.
