Abstract (en)
[origin: EP3195946A1] It is an object to provide a facility and a method for manufacturing a steel plate having excellent shapes and excellent mechanical properties, by performing uniform cooling in a cooling step by uniformizing scales that are generated on surfaces of the steel plate in a descaling step. A facility for manufacturing a steel plate includes a hot rolling apparatus, a shape correcting apparatus, a descaling apparatus, and an accelerated cooling apparatus which are set in this order from an upstream side in a conveyance direction, wherein jetting nozzles of the descaling apparatus are set in two rows with respect to a longitudinal direction of a steel plate, and wherein energy density E of descaling water that is jetted towards a surface of the steel plate from the two rows of jetting nozzles is greater than or equal to 0.08 J/mm 2 in total.
