Abstract
An insert is provided for a continuous caster mold which permits casting of plural strands in the mold. The insert has opposed wall faces, the spacing of which is independently adjustable at their upper and lower ends. The spacing of the upper and lower ends is made adjustable by separately actuable wedge assemblies, each of which includes a wedge and ramps having mateable angularly aligned surfaces. At least one surface in each pair of adjoining wedge and ramp surfaces has a convex curvature to permit adjustment of the angular alignment of the wall faces as required at the various spacing distances thereof. The wedges provide greater rigidity than screw-type adjustment, preventing undesirable variations in taper during casting. The invention includes a method of installing the insert in the mold and adjusting the spacing and angular alignment of the opposed wall faces of the insert.
