Title:
COLD-ROLLING FACILITY AND COLD-ROLLING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/115156
Kind Code:
A1
Abstract:
A cold-rolling facility in one mode of embodiment of the present invention heats successively-conveyed steel plates using a heating device, and successively cold-rolls the heated steel plates using a tandem rolling mill, and is provided with a meander amount measuring unit, a meander correction device, a shape measuring unit, a shape control unit and a control unit. The meander amount measuring unit measures the amount of meander of the steel plate prior to heating by the heating device. The meander correction device corrects the meander of the steel plate prior to heating by the heating device. The shape measuring unit measures the shape of the steel plate after cold-rolling by the most upstream rolling mill in the tandem rolling mill. The shape control unit controls the shape of the steel plate after cold-rolling by the most upstream rolling mill. The control unit controls the meander of the steel plate prior to heating by controlling the meander correction device on the basis of the measured values of the amount of meander, and also controls the meander of the steel plate attributable to rolling by controlling the shape control unit on the basis of the measured values of the shape of the steel plate.
