Abstract
714,728. Mould and core materials. BEILHACK, M. Feb. 29, 1952, No. 5333/52. Class 83 (1). Mould or core material comprises silica sand, hydraulic binding agent, a wood derivative and molasses. In examples, 100 parts by weight of silica sand may be mixed with 8-10 of cement, 0.5-1 of celluse pitch powder, 0.3-0.7 of clay, 1.6-2.6 of molasses and 5-10 of water, with or without coal dust or natural or artificial resin. The moulds or cores may be dusted with coal dust or graphite or coated with blacking. Boxless moulds may also be made. Old moulds may be ground and sifted and the sand so produced be used in place of some of the new sand, such a mixture being 95 parts by weight of recovered sand, 5 of new silica sand, 1-2 of cement and 0.8-1.5 of the molasses &c. binder. The material, with the exception of the cement, may be mixed and supplied in liquid or powder form, ready to be added to the sand, cement and water.
