A method for making long metal rolled products by continuous casting, made by a continuous casting machine to two casting lines; shearing to size of the cast product; direct introduction of each segment, having an average temperature of at least 1000° C.-1150° C., into a maintenance and/or heating furnace that has a first and a second movement sections, each of the movement sections is disposed in axis respectively with one of the two casting lines to receive a respective segment; lateral transfer of each segment inside the furnace to dispose each segment in a third movement section disposed parallel and misaligned with respect to the first and the second movement sections and aligned to a rolling axis of a rolling line parallel and offset with respect to the two casting lines; and reduction of the section in a rolling mill defining said rolling axis.
