Abstract
1,160,090. Mould-lining and core-coating materials. A. DUNLOP. 17 July, 1968 [18 July, 1967], No. 32995/67. Heading B3F. [Also in Divisions B5 and C3] Refractory moulds for precision castings, particularly of highly reactive metals, e.g. titanium and titanium base alloys, are produced from a slurry of refractory, binder and gelling agent which is subsequently heated to form a crazed structure, e.g. as a mould lining, which is then further strengthened by application of a further binder and impregnated with graphite. The slurry 20 may be applied to a poured or rammed refractory backing layer 17. Further binder may be applied by dipping into a liquid binder solution. Graphite impregnation may be achieved by placing the mould in a heated furnace and admitting a gaseous hydrocarbon thereto which is carbonized or by placing the heated mould in a container to which the hydrocarbon is admitted. Impregnation may also be achieved by incorporation of finely divided carbon into the liquid binder solution. The refractory material may be refractory oxides, silicates or carbon and the binder may be an alcoholic solution of phosphorus pentoxide, aqueous phosphoric acid, sodium silicate or hydrolysed ethyl silicate.
