Abstract
PURPOSE: To obtain the slab width distribution of the slab to be rolled immediate before edging rolling by setting the roll spacing where width screw-down is applied over the entire longitudinal direction of the slab material and detecting the actual rolling load distribution in performing edging rolling of the slab material.
CONSTITUTION: The longitudinal direction position l of the slab material to be rolled SLAB is detected with a device PG and the rolling load P is measured with a device LC, from which the rolling load distribution is detected with an arithmetic unit CPU. In the first pass of rolling, the spacing of the rolls ER where screw-down is always applied in each position of the longitudinal direction of the slab material is determined and a roll spacing is set in that spacing, then edging rolling pass is performed and the rolling load distribution (rolling load values in the respective positions in the longitudinal directions) is detected. From the predetermined reference rolling load distribution of the slab material to be rolled and the actually measured rolling load distribution, the slab width distribution of the slab material to be rolled immediate before edging rolling is estimated.
