Abstract: In a method and means for oxygen cutting of cast strands and steel workpieces or downstream of continuous casting plants, by means of a membrane (9) controlled pressure measuring and regulating valve (1) with pressure and flow converters (16, 17, 18) on the basis of predetermined reference values, supply of a cutting nozzle of a cutting torch with heating gas and heating oxygen for generation of an optimum cutting flame is electrically and/or electronically adjusted, readjusted or shut down and/or predetermined maximum deviations from the reference values are recognized, indicated and used for signalling or cutting torch shutdown. A time-consuming regulation of the cutting flame of the cutting torch is avoided as a result penitent variable delivery of heating gas and heating oxygen to the cutting torch.

Abstract: A deburrer machine for cutting burrs (2), which consists out of a rotating deburring body (3) and travelling carriage (6) is foreseen for application especially on longitudinally cut slabs in flow. For deburring the deburring pistons (4) perform a rotary movement around the deburring body axis (21), whereby they approach to the cutting burr (2) from the workpiece side. Therefore the rotation axis is arranged in a way that the deburring pistons (4) turn below the lower workpiece surface outside the workpiece (1) after having finished the deburring procedure in order to lift again against this lower surface. Inside the deburring body (3) is placed a pressure chamber (18) which effects the lifting of the deburring pistons (4). Thereby the air contained in the lower piston guidance (12) is displaced and then the throttled air is led-off via bores in the lower part of the deburring piston (4) in order to dampen the piston movement.

Abstract: A unilateral or bilateral device which granulates torch cutting slag underneath the material and underneath the cutting torches (2), while synchronizing with the torch cutting machine (1), which is equipped with new nozzle assemblies slightly tilted outwards, the nozzle assemblies being arranged in a new way with shroud-spraying nozzles (11) and new jet-spraying nozzles (10) at low, work specific inlet pressures and a comparably low requirement of water. Very good granulation results with regard to the torch cutting slag produced during the torch cutting procedure. At the same time the nearby components are protected from slag fouling, the slag can be removed without any problems, and exhaust gases can be purified owing to the floating particles being washed out therefrom.

Abstract: An oxygen cutting machine (1) is designed for a billets, blooms, slabs or heavy plates in a pair of up and down arranged rails (3) having a novel heat protection plate (6) and no uncooled machine parts below the rails (3), which moves sideways with a drifting work-piece (2) being a clamping system, having a clamp down skid (10) to cover various thickness of work-piece (2) and can be used with so-called cutting push bars (24) for cutting against each other of two oxygen cutting burners (9). A new oxygen cutting burner (9) or nozzle quick exchange system improves use and maintenance. Cutting safety and cut quality are improved by the gas control for pressures and mass flow near the burners. A novel roll deburrer (32) to deburr just oxygen cut strand pieces (2) after the oxygen cutting machine (1) facilitates the to and fro deburring and the transport of extremely short pieces over the deburrer gap.

Abstract: The invention shows a travelling deburrer for cutting burrs (2) developing when steel strands are subdivided by oxygen cutting. The deburrer achieves safe deburring with high deburring rates with the help of cost and space reducing designs regarding drive, control and tools, by increased deburring energy and by a more advantageous blade design.

Abstract: In this application for protection rights a new deburrer is presented, in which the deburring device working on a slab (1) or a billet (1), as a stationary design moves the work piece with an integrated pusher drive or includes a pusher drive when designed as a travelling device.

The apparatus includes extendable pistons having deburring tools mounted thereon. The deburring tools are arranged such that rotation between adjacent tools is substantially prevented. Compressed air containing a lubricant is used to extend the pistons and cool the deburring tools.

Abstract: Use of a mass flow cock with control units and pressure reducing systems results in an even output at changing exit dimensions respectively nozzle exit bores by an automatic balancing of the process volumes, reduces thereby the equipment expenditure and increases the maintenance intervals. This mass flow cock operates using a large pressure difference and an exact adjustment of a special cock piece at two diaphragms.

Abstract: By means of an extended nozzle head having several excentrical nozzle receptions although the cutting oxygen is in line with the cutting jet bores, rotation of the nozzle head or of the total lower part of the burner can bring the working cutting nozzle into correspondence with a determined cutting line; being manifold equipped the thickness of a sample slice can be between two cutting nozzles selected by rotation or a spare nozzle can be put into operation quickly in case of breakdown. The nozzles for sample cutting or replacement are covered behind a protection plate against splash and flames. The protection plate can serve as well as a guide for a save pilot flame. The flexible connection of the adjustable burner and its gas supply is performed by metallic piping accordingly shaped and dimensioned.

Abstract: A continuous casting slab cutting apparatus is disclosed. The apparatus permits a slab to be cut from a strand of continuous casting using a synchronized strand cutting machine. A slab roller table having a set of slab rollers is positioned such that as the strand cutting machine passes over the moving strand, the cutting burner is never positioned over any of the slab rollers. Also disclosed is a system for containing and removing smoke and other gases generated by the cutting process from the strand cutting area. The containment system includes partitions and plates as well as ventilation ducts positioned at various areas within the cutting area.
