ABSTRACT:
A metal scarfing apparatus having provision for controlling the scarfing depth of cut in separate areas across the width of the hot workpiece, to thereby compensate for the effects of temperature and/or quality variations and achieve a uniform surface. The apparatus comprises a gas distribution manifold having an internal gas distribution bore, and the bore communicates via a plurality of radial drillings with each of a plurality of scarfing units mounted to the manifold in a side-by-side arrangement. The bore in the manifold is divided into three chambers having separately controllable gas delivery systems, so as to permit independent control of the depth of cut in each of the width segments of the workpiece corresponding to the three bore chambers. Also, the central chamber of the bore is adjustable in length so as to accommodate workpieces of varying width.
