Measures and Practice on Improving Rolling Efficiency of Double Stand Heavy Plate Mill
Aiming at the situation that the short distance between roughing mill and the finishing mill has a great influence on the rolling rhythm in Laiwu Steel 4 300 mm heavy plate mill,the measures such as the grouping of roller tables,the optimization of the logic control of roller tables and the shortening of the spacing of the slabs to be heated are adopted,the length of the roller table to swing is increased to the maximum,and the number of batch rolling is increased.The time wastage was reduced by optimizing the function of steel connecting on roller table,developing the priority judgment of steel dividing and optimizing the control of finishing mill bite steel.Downtime caused by material tracking errors with the tracking material image hold function is reduced.The implementation of the above measures has increased the production efficiency of the production line by more than 15%.
