310S不锈钢热卷表面氧化铁皮磁性研究及EPS表面处理工艺实践

Research of Magnetic Property of Hot Rolled Plate Oxide Scale and Production Practice of EPS Treating Technology

通过实验室电加热炉,获得了310S不锈钢热轧板表面氧化铁皮。对获得的氧化铁皮进行了磁性吸附实验、物相分析、扫描电镜形貌分析。实验结果表明:奥氏体不锈钢310S不锈钢热轧板氧化铁皮是完全具有磁性的尖晶石结构,可以通过EPS处理去除大部分的氧化皮。310S钢卷通过EPS处理后,热卷的酸洗效率能提高一倍。

The oxide scale of hot rolled plate of 310 S stainl ess steel was obtained in laboratory furnace,and the heating temperature and heating time of hot rolling heating furnace was simulated by laboratory.The magnetic of oxide scale was test by magnetic absorption experiment,phase analysis and SEM analysis.The experiment results showed that:the oxide scale of hot rolled 310 S stainless steel plate is spinel structure,which is complete magnetic and can be removed by EPS treating.The pickling efficiency of 310 S stainless steel was increased once by EPS treating.
