Abstract
PURPOSE:To reduce development of side strain and to improve the yield and value as goods by working the one side edge part of the strip before annealing more than the other part, winding and annealing while laying the worked edge part so as to bring into contact with a coil receiving table. CONSTITUTION:The one side edge part 1-1 in the strip coil 1 before annealing is worked at >=30% more than the other part by using a roll having projection, etc., to give excess working strain to there. This is wound to the coil and the worked one side edge part 1-1 is laid as positioning at lower end so as to bring into contact with the coil receiving table in an annealing furnace. Next, box annealing is executed at the optional heat cycle. As the worked edge part 1-1 is formed to finer grain than the other part, the mechanical strength becomes high and the development of the side strain can be reduced or prevented.
