Abstract

PURPOSE: To mass produce the square shape steel in the continuous rolling line, by rolling a falt slab with the breakdown mill into a rough shaped steel material of approximate W type section, and next, by processing this material with the universal forming mill and the shape reforming mill to finish it into a closed-sectioned shape steel.
CONSTITUTION: After being heated and soaked in the heating furnace, the flat slab 1 is fed to the breakdown mill 10 where the slab 1 is roughly rolled through two rolling passes into a rough shaped steel material 3 possessing a moderate approximate W type section of short height and wide breadth. Next, this material 3 is sent to the universal forming mill 11 and is roll formed into an open-sectioned material 4 with wall thickness equal to that of the final product. Then, this material 4 is subjected to the shape reforming pass by the reforming mill 12 like as the two-stage caliber mill, etc., and a closed-sectioned square steel shape 5 is obtained. The black skin is removed away from the groove of this material 5 whose seam is then welded or forge welded; after that, the final product is finished through a strightening pass.
