摘要
针对首钢京唐钢铁联合有限责任公司2250mm热轧生产线出现的管线钢头尾宽度偏窄、展宽轧制时宽度控制效果不好、立辊短行程参数维护繁琐效率低等问题,采取了将板坯上下表面温差控制在30℃以内、避免叩头板坯在定宽机处出现打滑、优化定宽机与立辊负荷分配、严格控制来料板坯宽度、开发新的立辊短行程维护工具等改进措施,取得了很好的效果。
In view of the problems,such as narrow of head and tail,width control effect bad of pipeline strip,the low maintenance efficiency of vertical roll short stroke parameters of 2250mm hot strip rolling line in Shougang Jingtang United Iron and Steel Co.,Ltd.,the slab surface temperature difference was controlled within 30℃,slab slipping was avoided in wide sizing mill,the load distribution of vertical roll mill was optimized,the slab width was strictly controlled,and the new maintenance tools was developed for vertical roll mill.Based on these measures,good effects were obtained.
