摘　　要：通过扫描电镜分析红色条带状缺陷主要成分是Fe、O,针对该缺陷分析了氧化铁皮主要缺陷类型、形成机理和A36Cr表面红色氧化铁皮的形成原因,并采取调整加热炉加热制度和降低Si含量的措施,将带钢表面合格率从64.5%提升至95.5%。The main composition of red banded defect is Fe and O through analyzing with the scanning electron microscope. In the paper,the types of main defect and formation mechanism of scales as well as the causes for red scales on surface of A36 Cr are analyzed aiming at the defect. Such measures as adjusting the heating cycle of heating furnace and reducing the content of Si are taken to improve the surface percent of pass of strip from 64. 5% to 95. 5%.
