摘要
舞钢4100 mm粗轧机在轧钢过程中衔接加热炉和精轧机,对于整条轧钢产线产量的提升起到承前启后的重要作用。加快粗轧机轧制节奏,不但可以加快加热炉出钢节奏,而且能够进一步加快精轧机轧制节奏。通过提高粗轧机机前辊道速度、推床夹钢速度和转钢辊道转钢速度,同时优化推床动作逻辑、平衡块确认逻辑、压下动作速度以及压下系统动作确认逻辑,可以缩短轧机等待时间,提高轧机作业率,减少道次响应时间,增加粗轧机产量,进而推动整条轧钢产线轧制节奏提升。
Being the connection between the reheating furnace and the finishing mill in the process of rolling,the 4100 mm roughing mill in Wusteel plays an important role in improving the output of the entire rolling line as the process transition.The improvement of roughing mill pacing can not only accelerate the discharging pace of the reheating furnace,but also further accelerate the finishing mill pacing.By increasing the speeds of entry roller table,the side guides centering and turntable slab turning,optimizing the side guide action logic,balancing block validation logic,screwdown action speed and screwdown system action validation logic,the mill waiting time is shortened,the mill availability ratio is improved,the pass response time is reduced,the output of the roughing mill is greatly increased,as a result,the pacing of the entire rolling line is improved.
