对SUS430不锈钢冷轧时的表面条带状色差缺陷进行了分析,发现缺陷在罩式炉退火后已经产生,缺陷产生的根源是捆带表面涂漆中的氧扩散。通过控制自动打捆模式,改变手动打捆位置和变更捆带材质可以杜绝该缺陷发生。 The surface strip-like chromatic aberration defects of SUS430 stainless steel during cold rolling were analyzed and it was found that the defects had been produced after annealing in the bell furnace. The root cause of the defects was oxygen diffusion in the surface of the strap. By controlling the automatic bundling mode, changing the manual binding position and changing the binding material can prevent the defect from occurring.
