The process in which rolling is executed by the recuperating stage between passes in reverse rolling is repeated one or more times, the rolling average temp. of the flange is regulated to <=950 deg.C and the total draft is regulated to >=20%. The outside face of the flange is cooled at 0.5 to 10 deg.C/sec cooling rate in accordance with the thickness of the flange. In this way, the carbon equivalent can be aggregated to two kinds of 0.21 to 0.25% and 0.29 to 0.37%.
