摘要
河北新金东炼钢厂热轧卷板在产品开发、生产过程中曾产生少量的夹杂、起皮等缺陷,给生产控制和产品经营带来负面效应,尤其是产品夹杂、起皮缺陷,一直以来断续出现。认真研究了相关文献及生产现场情况,通过调整炼钢操作和对起皮缺陷进行金相组织分析,找到了缺陷产生的主要原因。通过控制中包塞棒的氩气流量和结晶器液面波动等措施,大幅度地减少了热轧卷板的夹杂、起皮缺陷。
In development of hot rolled coil in our company, some inclusion or wrinkling on the coil is always been brought out, and has bad effect on our production and merchant. We seriously studied the concerned files and the status of site production, adjusted steel - making operation and analyzed the metallographic structure of the wrinkling products, found the main reason. The defects are reduced to a large extent with measures： controlling argon flow rate of tundish stopper and mold level fluctuation.
