A working beam type heating furnace was comprised of movable skid beams and fixed skid beams, wherein the fixed skid beams are supported by cross beams each having both ends fixed on the side walls of the heating furnace, with intermediate members downwardly extending from each of the fixed skid beams to a cross beam to make a prescribed space between the fixed skid beams and the cross beams support pipes for supporting the movable skid beams, and the hearth being formed for free movement by connection with a driving device.
