热卷表面氧化铁皮状态对冷轧产品表面的影响

Effect of Scale State of Hot Coil Surface on the Surface of Cold Rolled Products

随着下游冷轧用户生产成本质量要求提升,其对冷轧表面越来越关注,虽然冷轧通过酸洗能改善冷轧入口带钢表面状态,但是目前大部分冷轧用户所使用的设备仍是简单的推拉式酸洗机组,对热卷表面氧化铁皮去除的能力有限,变相的对热卷表面氧化铁皮提出了更高的要求.

With the improvement of production cost and quality requirement of downstream cold rolling users,they pay more and more attention to cold rolling surface.Although pickling before cold rolling can greatly improve the surface condition of cold rolling inlet strip,at present most cold rolling users are still simple Push-pull Pickling units with limited ability to remove oxide scale on hot coil surface and disguised iron oxide on hot coil surface.Pi put forward higher requirements.
