Abstract
PURPOSE:To stably produce a hot rolled steel sheet having excellent scale adhesiveness and formability by hot rolling a low-nitrogen extra-low carbon steel slab under specific conditions. CONSTITUTION:The low-nitrogen extra-low carbon steel slab having the compsn. contg., by weight %, <0.0050% C, <0.010% S, <0.50% Mn, 0.010-0.080% Al, and <0.0080% N is hot rolled and the finish rolling thereof is completed at 800-700 deg.C to form the hot rolled sheet which is then coiled at 650-570 deg.C. This steel sheet is slowly cooled at <=10 deg.C/hr cooling rate in a 570-500 deg.C range, by which the scale layer is converted to Fe3O4. The hot rolled steel sheet which has the excellent adhesiveness of scale and obviates the stripping of the scale at the time of forming is thus stably produced.
