PURPOSE:To perform hot rolling while maintaining a stable shape of stock by adhering same kind of metals of the same thickness to both sides of the front end of a clad-steel slab before rolling the slab. CONSTITUTION:In case of hot rolling a slab of clad steel clad with metals different in thickness or one-side clad steel, same kind of metals 3, 3' of stainless steel, etc. are adhered to both sides of the front end of clad steel. This slab is hot rolled into a clad steel for thin sheet. The thickness (t) of metal 3 is preferably restricted to about 1/2 of the sum of the thicknesses of clad metals 2, its length (l) to >=1-<=3 times the slab thickness, and the difference in thickness between the outside and inside metals 3, 3' to within 3%. In this way, the strengths and elongation percentage of both sides of the front end of rolling stock, in hot state, are made equal to each other, and the rolling efficiency is enhanced.
