PURPOSE:To roll and manufacture the high quality wide flange beam with simple facilities, by carring out the continuous reverse rolling with the roughing universal mill and the universal edger mill arranged in the latter stage of the breakdown mill, and then, by rolling with the universal finishing mill. CONSTITUTION:In the rolling line L, the roughing universal (Ru) mill 2 and the universal edger (uE) mill 3 are sequentially arranged closely at the latter stage of the breakdown (BD) mill 1, and the universal finishing (uF) mill 4 is arranged at the latter stage of the uE mill. At the BD mill 1, the bloom or beam blank is reverse rolled to form the roughly shaped H-beam billet 5 which is then continuously reverse rolled by the Ru mill 2 and the uE mill 3. At the uF mill 4, the finish rolling pass is executed by upper and lower H-rolls 13, 13, and the right and left V-rolls 14, 14. |
