Title: Flash removal from rolling slabs - produced by oxygen cutting continuously cast metal strands
IPC: B23K7/00
Filed: 1983-03-09
Abstract: The flash, formed, on the side away from the torch, in the oxygen cutting of rolling slabs from a continuously cast metal strand, is removed before passing to the rolling mill. A dividing surface is produced between flash and parent metal, e.g. by rapid cooling of the flash by a water jet, immediately it has solidified. This spreads the crack, where molten metal has solidified over scale on the parent metal, through the zone where welding has occurred. The back of the strand, in the cutting areas, may be coated to prevent adhesion, opt. with a heat barrier beneath. Coatings to reduce adhesion of the flash are known, but can be eroded by molten steel in the cutting zone. Rapid chilling of the flash to spread cracks through the welds permits its removal with the minimum use of space, and minimum loss of time and energy cooling the entire slab to remove it. A thin metal plate may be applied to the reverse surface for a similar effect, to be removed mechanically.

Abstract: TURBINE GENERATOR CYCLE FOR PROVISION OF HEAT TO AN EXTERNAL HEAT LOAD             ABSTRACT OF THE INVENTION       A steam turbine power plant having associated therewith a closed loop flow arrangement for extracting heat from the power plant and supplying the extracted heat to an external heat load.  Included within the flow arrangement is a predetermined number of heater elements, each of which extracts steam having a predetermined heating capacity associated therewith from a predetermined number of separate locations within the power plant.  The heat so extracted is transferred to a heat transfer medium flowing at a pre-determined flow rate within the closed loop arrangement.  The extracted heat is exchanged to the heat load within a heat exchanger element connected within the flow arrangement.          The amount of heat extracted from the power plant is functionally related to, and automatically limited by, the flow rate of the heat transfer medium within the closed loop arrangement.          The flow rate of the heat transfer medium is itself func-tionally related to the flow rate of the motive fluid for the power plant.
