英文摘要 | The rolling load of #3 and #4-5 motor at Rod Mill was nearly 100% rated capacity when rolling at speed of 70m/s, resulting in the production bottleneck. The purpose of this study is to evaluate the feasibility of solving the overload problen at #3 and #4-5 motor by modifing the rolling schedule and and rearranging the distribution of reduction among the roughing and intermediate stands, so that all the stand motor could be kept after the speed-up project being realized. The result shows that there are three advantages in this modified rolling schedule, ie, an increase in rolling speed from 70m/s to 80m/s, easier control of surface quality, and higher roll performance. The only disadvantage is a relatively bigger biting angle for intermediate stands, demanding more stringent operational adjustment due to higher reduction. |
