FIELD: manufacture of semifinished products in the form of thin metallic blanks. SUBSTANCE: for reliable keeping thickness allowance whose maximum value is equal to 2% at making blanks with width-to-thickness ratio more than 60, at output of melt bath metallic billet is passed between ironing rolls when mean temperature of generated crystal layer of metallic billet corresponds to predetermined value. In order to realize it ironing rolling apparatus is installed inside casing with possibility of changing its spacing from metal heel in range 0.5-5 meters. EFFECT: enhanced efficiency of method, improved design of apparatus. 14 cl, 1 dwg
