热轧带钢麻面产生原因分析及控制措施

Analysis and Control Measures for the Formation of Pitting on Hot-rolled Strip Steel

针对供冷轧用热轧带钢表面出现麻坑、麻面问题,文中结合德龙钢铁有限公司1250mm热轧生产线实际生产状况和机组情况,通过修订工艺制度、提高轧辊冷却水压力、启用机架带钢冷却水、调整水嘴型号和角度、改善轧辊材质等措施,有效的控制和减少了热轧低碳带钢的麻坑缺陷。

In response to the problem of pitting on the surface of hot-rolled strip steel for cold rolling,this article combines the actual production status and unit situation of the 1250mm hot-rolled production line of Delong Steel Co.,Ltd.Through revising the process system,increasing the cooling water pressure of the rolling mill rolls,activating the cooling water of the stand strip steel,adjusting the water nozzle model and angle,and improving the material of the rolling mill rolls,effective control and reduction of pitting defects in hot-rolled low-carbon strip steel have been achieved.
