METHOD FOR ROLLING H-SHAPE STEEL

摘要

PURPOSE:To contrive stabilization of dimensional accuracy by preventing fluctuation of flange width without using an equipment with complicated structure. CONSTITUTION:At the time of rolling an H-shape steel with flanges and web with a universal mill, spreading an amount of flange width is adjusted by applying finish rolling by taking the temp. in the connecting parts between the web and flanges of roughly shaped bloom for H-shape steel which rough rolling is applied and difference of reduction of area between the web and flange of that roughly shaped bloom for H-shape steel into consideration.
