Abstract

A tool for forming parting grooves in a flat, plastically deformable workpiece, e.g. a continuously cast steel slab, in a manner which seals the internal porosity of the slab in the regions which become exposed upon division, has a working portion in the form of a ridge, which is defined by an elongate ridge or preferably by a circumferential flange on a roll; the cross- sectional shape of the ridge or flange has a flat or convex tip between two straight or gently convex side faces, the angle at which the side faces are mutually inclined being 20 DEG to 60 DEG , the width of the tip being a given proportion of the thickness of the workpiece, and the width of the tip being specifically related to the said angle of inclination of the side faces. The height of the side faces, and their curvature and that of the tip, are also preferably within set limits. <IMAGE>
