It is an object to provide a facility and a method for manufacturing a steel plate which perform uniform cooling in a cooling step by uniformizing scale formed on a surface of the steel plate in a descaling step, to manufacture the steel plate having excellent shape. 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 disposed in this order from an upstream side in a conveyance direction, wherein an energy density E of cooling water that is jetted towards a surface of a steel plate by the descaling apparatus is greater than or equal to 0.10 J/mm 2 . |
