304不锈钢冷轧卷边鳞缺陷的成因分析及预防措施
|
Abstract:
本文介绍了304不锈钢冷轧卷边鳞缺陷的形貌与产生原因，针对产生原因及结合公司生产实际对边鳞缺陷进行分析，发现冶炼化学成分、板坯加热工艺参数是影响304边鳞缺陷的主要因素。因此，通过调整S质量分数、N质量分数及均热温度等措施，缺陷率由3.68%降至0.42%以下，边鳞缺陷改善明显，产品质量得到了显著的提升。
This article introduces the morphology and causes of edge scale defects in 304 stainless steel cold rolled coils. Based on the analysis of the causes and the actual production of the company, it is found that the smelting chemical composition and slab heating process parameters are the main factors affecting the edge scale defects in 304 stainless steel. Therefore, by adjusting the S mass fraction, N mass fraction, and soaking temperature, the defect rate decreased from 3.68% to below 0.42%, and the edge scale defects were significantly improved, resulting in a significant improvement in product quality.
