<p>PURPOSE:To improve productivity and yield by referencing the information on the finish thickness, target crown, etc., of a succeeding rolled stock and changing the moving quantity of work rolls at the time of cyclic movement in accordance with said information. CONSTITUTION:From a 1st stand up to a 3rd stand 3 are constituted of a four high mill, of which the work rolls 8 do not make axial movement. A 4th stand - 7th stand are so disposed that the work rolls 9 are axially movable. The incoming of the material requiring a sheet crown is preliminarily recognized in the rolling equipment constituted in such a manner and the work rolls 9 are cyclically moved at every rolling in accordance wit the information on the finish thickness, width, deformation resistance, target crown or target edge drop of the respective succeeding rolled stocks to control the moving quantity thereof within a <=100mm range. The effect of dispersing roll wear and the effect of controlling the edge drop are compatibly obtd. and the productivity and yield are improved.</p> |
