FIELD: metallurgy. SUBSTANCE: method comprises steps of cutting a metallic strip to measure-length blanks directly after rolling the strip in a rolling mill; applying on the hot measure-length blank a layer of easily meltable metal in the form of a powder or a sheet at temperature of the steel sheet less, than temperature of the easily meltable metal melting, rolling on a next hot measure-length blank by a press-shaft to a previous measure-length blank on the layer of the easily meltable metal; repeating steps of applying the easily meltable metal and laying of the measure-length blank with rolling it on by the press-shaft until providing a necessary thickness of a laminate sheet or plate, again being rolled in the rolling mill. EFFECT: enhanced quality of laminate sheets or plates. 2 cl
