Abstract

962,683. Treating mould and core materials. AVNET-SHAW PROCESSES Ltd. May 21, 1963 [June 4, 1962], No. 21503/62. Heading B3F. A method for recovering refractory aggregates from used casting moulds in which acidified sodium silicate or ethyl silicate have been used as binders comprises soaking the used mould in water until it disintegrates, dewatering the disintegrated material as by centrifugal or vacuum action and then passing the dewater material over successive screens through which hot air is circulated. Specification 774,184 is referred to.
