Abstract
A billet cutting apparatus of the type including an oxy-fuel cutting torch includes a slag removal nozzle operative simultaneously with the cutting torch to direct a jet of oxygen along the lower edge of the billet to remove slag beads tending to form thereon. The oxygen nozzle has a unique opening configuration which provides a thin, flat oxygen stream effective over a substantial distance, such that the nozzle can be mounted laterally of the billet and outside the hostile and potentially damaging environment created by the cutting torch and the hot billet. The nozzle may be conveniently mounted in a fixed position and, in an automated billet cutting apparatus, may be attached directly to one of the billet clamping arms.
