Abstract

1342290 Feeders in foundry moulds FOSECO TRADING AG 5 April 1972 [22 April 1971] 10859/71 Heading B3F [Also in Division B5] An investment casting mould is made by assembling one or more fusible or heat-destructible patterns having ingate lugs on to a central feeder at least part of which is in the form of a sleeve made from either a refractory heat insulating composition comprising inorganic fibres and a binder or an exothermically reactive composition, coating the assembled patterns with a refractory ceramic material and heating to remove the pattern and harden the coating, e.g. in a furnace at 1000‹ C. The sleeve may be closed at the end carrying the patterns and open at the other and may be formed of aluminosilicate fibres, starch and colloidal silica. A twolayer sleeve may have one layer of this material with additional alumina and a second layer comprising calcium silicate fibres. Examples of such sleeves forming the feeder of «trees» made by dipping in a slurry of alumina in colloidal silica and subsequently dry stuccoing with granular molochite, to be used for casting respectively gear selector forks and a turbine rotor are given.
