Abstract

848,386. Ingot moulds. FOUNDRY SERVICES Ltd. Dec. 22, 1958, No. 41384/58. Class 83(1). A hot-top, riser, or sinkhead comprises a support member 3 located in and suspended from the mould-head, hot-top &c., which will be destroyed at the temperature of the melt, and located on said support and spaced from the walls of the mould, hot-top &c. a solid preformed block or blocks 4 of exothermic composition, the space between said block or blocks and the walls of the mould &c. being filled with a backing 6 of refractory or mildly exothermic material. The backing may be granular or powdered material rammed into position, a preformed block or blocks, or preformed integrally with the exothermic block or blocks 3. Specification 829,156 is referred to.
