ABSTRACT
It is well known that the relative pro le of the hot-rolled strip does not noticeably change after the cold reduction in a tandem mill. Moreover, as the strip gets thinner in the subsequent cold-rolling passes, any irregularities of the strip pro le, such as buildup on both edges of the strip or a oneside edge buildup accompanied by a wedge condition, can cause local shape deterioration. Through simulations of the thermal conditions of the work rolls in the nishing stands of the hot strip mill, it has been established that the particular pattern of the roll cooling and the strip deviation from the mill centerline are among the root causes of the abovementioned hot band pro le irregularities. Experimental data have proved the ndings.
