Abstract

PURPOSE:To manufacture H-shape steel having a wide width flange stably and with good quality by the rolling mills in less number by forming the steel billet of after heating in the rough steel billet of a dog bone sectional shape and forming it in the same dimensional shape as that of the product H-shape steel excepting the flange inclination angle by executing its thickness reduction rolling immediately. CONSTITUTION:The blank stock steel billet of after heating is first subjected to rolling by the breakdown mill 15 having a grooved roll 18 and formed in the rough steel billet 19 of a dog bone sectional shape as shown by a broken line in an enlarged figure. This rough steel billet 19 is subjected to thickness reduction rolling by the universal mill 16 having a pair of the upper and lower horizontal rolls 20 and a pair of the right and left vertical rolls 21 to make the H-shape steel 22 whose flange inclination alpha is at <=1 deg. and whose flange thickness, web height and web thickness are in the same dimension as those of the specified product H-shape steel. Simultaneously the H-shape steel 24 obtd. by executing the shaping of the flange tip part and the adjustment of the flange width by an edger mill 17 is led to a roller straightening machine, etc., the flange inclination alpha is corrected to the specified product angle, 0 deg. for instance, to make the final product H-shape steel.
