摘要
针对薄板坯连铸连轧线生产高碳钢65Mn出现的表面翘皮问题,分析出缺陷产生的主要原因是铸坯边角部裂纹。通过降低二冷水量、合理分配扇形段水量分配比例等措施,有效地控制了65Mn板卷翘皮缺陷的形成,使高碳钢65Mn表面翘皮缺陷由10.03%降至0,取得了良好的经济效益。
The main reasons for surface peeling in 65Mn high carbon steel production in thin slab continuous casting and rolling line were analyzed and found to be slab edge and corner cracks. Measures of reducing secondary cooling water flow, reasonably distributing water flow at segments and etc. were taken to effectively control the formation of 65Mn coil lapping and reduce the surface lapping defect of 65Mn high carbon steel from 10.03% to 0. Good economic benefit was achieved.
