Abstract
PURPOSE:To minimize the thermal strain, and to carry out the rolling work under the stable condition, by carrying out the forming work while keeping horizontally the flange, at rolling the rough shaped billet with universal mill. CONSTITUTION:The heated billet is rolled by the break down mill into a rough shaped billet 4 possessing approximate H-form section. Next, the rough shaped billet 4 is laid so as to make horizontal its upper and lower flanges, and is rolled successively with the roughing universal mill 5, the jar mill 6, and the finishing universal mill 7. Hereupon, the mills 5, 6, become possible to roll the horizontal flanges with the horizontal rolls. And the extremely wide H-beam 1 with the flange length longer than the web length can be obtained from the rough shaped billet 4, without permitting the retention of cooling water on the flange of billet 4.
