Abstract

It is provided a steel sheet heating device (10) that heats a flat steel sheet (16, 60), characterized by including: a hot plate (12, 14, 40) having a flat heating surface (12f, 14f, 42f, 44f, 46f) brought into close contact with the steel sheet; and a plurality of heating equipment (18, 18a-18m, 52) able to heat a plurality of heating regions (20a-20d, 42, 44, 46), formed by dividing the heating surface of the hot plate into a plurality of sections, to different heating temperatures at the same time, wherein the steel sheet is heated to different temperatures at various portions based on the heating temperatures of the plurality of heating regions of the heating surface, at the same time through a single heating treatment.
