ABSTRACT:
A heating bath including molten metal is situated at an entry into a hot roll mill such that the metal stock entering the hot roll mill passes through the heating bath to acquire heat therefrom. A cooling bath including molten metal is situated at an exit from the hot roll mill such that the metal stock exiting from the hot roll mill passes through the cooling bath delivering heat thereto. The molten metal in each of the baths is caused to flow counter to the direction of passing of the metal stock therethrough to form within each bath a hotter fraction and a cooler fraction of the molten metal. The molten metal is circulated between the heating bath and the cooling bath so that a hottest fraction of the molten metal in the cooling bath is transferred to the heating bath and a coolest fraction of the molten metal in the heating bath is transferred to the cooling bath.
