Patent ID: 10213860

Abstract:
A scarfing head (100) is proposed for scarfing a surface of a workpiece produced by casting, in particular a slab, with a gas outlet side (400) for gases for scarfing, wherein a flame for scarfing can be formed at the gas outlet side; with a plurality of cutting nozzles (120) which are individually fixed on the gas outlet side; and with a central gas conduit (110) in the scarfing head; wherein the plurality of cutting nozzles (120) are disposed around the central gas conduit (110); wherein the scarfing head (100) is so designed that heating gas (150) and heating oxygen (150) can exit through this plurality of cutting nozzles; and wherein the scarfing head (100) is further so arranged that scarfing oxygen can emerge through the central gas conduit (110). Thus a particularly high heating performance is achieved over a comparatively large area. The maintenance and cleaning of the scarfing head is significantly facilitated through the use of many individually fixed cutting nozzles.
