Abstract
In this paper, we show that lateral forces and bending moments, respectively, acting on a slab during hot rolling can induce lateral material flow in the roll bite. Furthermore, we present an automation scheme that allows for reducing wedge in a roughing mill stand without generating camber. Thus, camber can be decoupled from wedge and hence roll tilting in the roughing mill stand can be used to control the wedge in the rolling process. A slab-toslab control algorithm is presented using the measured wedge of the finished strip as input and the tilting of the roughing mill stand as actuator.
As a key to success, we apply the edger to induce the required lateral forces in the upstream passes. Because only equipment is applied that is available anyway, no further investment in hardware is required to benefit from this automation scheme.
