ABSTRACT:
A hot rolling method, wherein portions of a hot-rolled steel material having suffered a temperature fall below Ar.sub.3 transformation temperature thereof during hot rolling are subjected to an intermediate heating to have a temperature not less than Ac.sub.3 transformation temperature before the steel material is finally finish-hot-rolled, whereby a resultant hot-rolled product can have a superior uniform structure without duplex structure, and apparatus for effecting the method.
