In 1980, slab sizing mill was constructed at Oita Works, Nippon Steel Corporation, which is V-H-V stands. (V: Vertical, H: Horizontal).
This mill is 3 stand tandem mill, and rolls the width of continuous casting slabs.
The products of this mill is sent to hot strip mill and plate mill.
This paper describes the mill, and interstand tension control. It utilized the rolling torque and the rolling force, in particular, the rolling torque was separated from the acceleration/deceleration torque. And the interstand tension was controlled within ±0.2 kgf/mm2 by free tension control. Thus high accuracy width deviation was attained.
