摘要： PURPOSE: A method and an apparatus for rough-rolling thick sheets are provided to enable pressure drop and also prevent sheets from being gammed by correcting reduction ratio based on the critical reduction ratio for each thickness after deciding the reduction ratio proper for each thickness. CONSTITUTION: A method for rough-rolling thick sheets is as follows. A reduction ratio{r0(i)} for each pass is decided based on a facility allowable range of a rolling mill(S126). The critical reduction ratio(rc) for each thickness in which jamming sheets can be occurred is decided from the reduction ratio for each pass(S130). In order to obtain a target thickness(Ht), a reduction ratio for distributing the reduction ratio of whole pass is redistributed(S142). Based on the critical reduction ratio for each thickness, the reduction ratio is corrected to prevent the sheets from jamming(S155).
