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.

Abstract: Scarfing machine (1) for scarfing hot and cold work pieces (2), such as slabs, blooms and billets made from steel in and downstream of continuous casting plants with a roller table (3) arranged in the direction of transport of the work piece, on which the work piece (2) to be scarfed can be moved back and forth. The scarfing machine (1) is set up in a gap (4) formed in the roller table (3) which has a U-shaped beam (7) with a scarfing unit (10) in the form of a rack of manifolds arranged crosswise to the roller table (3). The height of the burner beam (7) can be adjusted and it can be pivoted approximately 180° on a horizontal axis (8) around the top, bottom and cut sides of the work piece (2) by means of a swivelling drive (6) while the work piece is moved back and forth.

Abstract: The invention relates to a nozzle (1) for cutting steel workpieces and workpieces made of iron alloys, comprising a nozzle body (2), wherein the nozzle body (2) has two cutting-oxygen bores (5, 5a), which extend from an inlet side (6) of the nozzle body (2) to an outlet side (8) of the nozzle body (2) in order to form two cutting jets (10, 10a). The double cutting flame cuts the steel more strongly in the so-called groove trail. The cut is thus more effective. This permits an increased cutting speed, which in turn causes a reduction in the heating-gas consumption.

Abstract: Using machines, equipment and devices for mechanical scarfing off of oxygen cutting burr from workpieces of steel, the deburring will be safer with a better deburring ratio, lower cost and with better, advantageous maintenance and wear part situations. The scarfing process performs even if limited, step by step continuously, following in every height level of the cutting oxygen burr with a tool continuously moving from down to up with a suitable adjustment.

Abstract: Owing to the application of a cone stub with scarfing knives on a drive that is positioned at an angle and the resilient adjustability of the cone stub, a safe and economical deburring process using only marginal space is possible.

Abstract: A high pressure oxygen torch system for cutting steel is disclosed. The system includes a high pressure nozzle which operates at oxygen pressures of approximately 20 bar and above. The system also includes a pressure regulating valve and a mass flow control valve which maintain uniform pressure within close tolerances. The oxygen torch system may be used in continuous steel casting operations to economically, reliably and quickly cut hot and cold strands.
