Abstract of the Disclosure A continuous-casting mold for strip steel has relatively long side walls have inner surfaces bridged by and forming an upwardly open passage with relatively short end walls. Liquid metal is continuously introduced from the lower end of a dip tube into the top of and withdrawn from the bottom of the mold such that the liquid metal has an upper surface at a predetermined normally stationary level in the mold. The inner surfaces are each formed by a planar lower portion wholly below the level, a central portion offset inward from the end walls and extending from the respective lower portion up above the level, a pair of planar intermediate portions coplanar with the respective lower portion, wholly below the level, and each extending between the respective central portion and a respective one of the end walls, and a pair of planar upper portions coplanar with each other, extending from the respective intermediate portions upward past the level, and flanking the respective central portion above the respective intermediate portions. The upper portions of one of the side walls diverge upward from and form an angle of between 1° and 3° with the upper portions of the other side wall. The lower portions extend parallel to each other the full width of the mold between the end walls and the central portions flank the dip-tube lower end and diverge upward. The end walls are of uniform horizontal width below the upper portions and are of a width increasing uniformly upward along the upper portions.
