Abstract: A method of controlling the rolling efficiency in a continuous hot rolling process including the steps of inputting a total weight of and the time intervals of slabs already extracted from a heating furnace in a period from the present time up to any previous time, a total weight and a forecast furnace residence time of slabs charged in the heating furnace and a total weight of any number of slabs to be charged, and calculating the desired rolling efficiency of the slabs to be charged to thereby control the overall average rolling efficiency to a predetermined value. With such a method, the total weight of the slabs to be rolled in a unit time is maintained to a predetermined value.
