Title:
CONTROL METHOD AND CONTROL DEVICE FOR SIZING PRESS DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/060124
Kind Code:
A1
Abstract:
This control method for a sizing press device is a control method for a sizing press device (2), which is provided with a pair of molds that are disposed in a plurality of vertical stages and can shift in a direction orthogonal to a transport direction for slabs, and wherein molds that carry out width rolling processing on a slab between the upper stage molds (21A, 21B) and lower stage molds (22A, 22B) are replaced at each of a prescribed number of slabs and wherein the molds are cooled without carrying out width rolling processing, and includes a step for determining the prescribed number of slabs with the number of slabs for which width rolling processing is carried out continuously by one mold such that a heat cycle frequency applied to the mold per unit time is a prescribed value or greater as a lower limit value.
