PURPOSE:To prevent generation of heat streaks and to eliminate a cold rolling stage by specifying a range of rolling temps. and a range of scale thicknesses during at least one pass for hot finishing rolling of a low carbon steel strip. CONSTITUTION:A low carbon aluminum killed steel, etc., are cast, roughly rolled, and then are hot finished rolled into strips having a prescribed thickness. In that finishing rolling, warm rollings are performed at a rolling temp. in the range of 200-700 deg.C and with a scale thickness in the range of 0.1-3mum. In this method, the heat streaks are prevented from generating and pickling is easily performed.
