<P>PROBLEM TO BE SOLVED: To efficiently conduct controlling without changing the layout of a hot rolling line and causing cooling waiting time during rolling by a reversible rolling mill on the downstream side. <P>SOLUTION: When rolling has been completed by a rough rolling mill, a cooling applicable time t0 until the time when a material to be rolled is started to be rolled by a finishing mill, and a rolling start target temperature θt in the finishing mill when the temperature of the material to be rolled is made below a non-recrystallization upper limit temperature θα when the material to be rolled has been rolled up to an optional intermediate plate thickness on the midway of rolling by the finishing mill, are estimated, and the water cooling time tw by a cooling apparatus is calculated and set on the basis of the estimated results. <P>COPYRIGHT: (C)2012,JPO&INPIT |
