PURPOSE:To provide a titled mill train which enables the advantageous hot rolling of a thin plate from a thick base plate by disposing a high draft mill such as a planetary mill in the fore stage and tandem finishing mills in the post stage. CONSTITUTION:A thick base plate of about 50mm. is passed through an inlet side 1 and is hot-rolled with a high draft mill such as a planetary mill F, a centrifugal roll cast mill or high draft tandem roughing mill or the like disposed in the fore stage and ordinary tandem finishing mills F5, F6, F7 disposed in the post stage, whereby an extra thin finished steel plate of about 0.8-1.2mm. is finished on an outlet side 2 at a desired temp. It is more preferable to dispose a rolling mill having good shape controllability such as HC mill or the like in place of the ordinary mills F5, F6, F7 as the rolling mill in the post stage in order to prevent the generation of inconvenience in shape. |
