Abstract: A deburring apparatus for cutting beards formed at edges of slabs as a result of torch cutting of strands during continuous steel casting operations is disclosed. 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: 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.
