摘　　要：针对汽车大梁钢表面存在的红色氧化铁皮缺陷,在生产汽车大梁钢610L时,根据在线表面检测仪采集的带钢表面红色氧化铁皮图像,按照红色氧化铁皮分布数量来量化其程度大小。结果表明,红色氧化铁皮的严重程度与加热时间直接相关,查询对应时间段的煤气中H2S含量达到300 mg/m3以上,可确认H2S是导致红色氧化铁皮的主要原因,为此减少了煤气中H2S含量,红色氧化铁皮得到有效遏制。Aimed at the red iron oxide scale defect on the surface of 610L strip for automobile frame,the level was quantified according to the images of surface inspection equipment.The results showed that the defect level of red iron oxide was directly related to the reheating time.Meanwhile,the H2S content history curve was checked and found out that the H2S content in gas reached 300 mg/m3.So it showed that the main cause of red iron oxide scale defect was H2S content.Then by reducing the content of H2S in gas,the red iron oxide scale on the 610L strip surface was completely improved.
