<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a band steel for blades capable of mitigating the stresses remaining in the band steel for blades after the band steel is slit to the product width, and suppressing any deformation of the shape of a worked semi-finished product. <P>SOLUTION: In the manufacturing method of the band steel for blades, a finished cold rolled material with its thickness being≤0.15 mm through the finish cold rolling is subjected to the coil-slit processing, and thereafter, the coil-slit steel for blades is passed through a continuous annealing furnace to execute the stress relieving annealing in the atmosphere of non-oxidizing gas in the temperature range of 500-630°C. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
