ABSTRACT:
A mill including large-diameter work rolls which are directly driven is disposed in an upstream stage of a hot strip finish rolling mill train, and mills including small-diameter work rolls which are driven by back-up rolls or intermediate rolls are disposed in middle and downstream stages of the hot strip finish rolling mill train, so that a strip can be rolled with strong draft and at a low speed, whereby a small-scale production of hot strips on the order of million tons annual yield can be achieved with a compact structure of equipment.
