Abstract

1281082 Casting processes FOSECO TRADING AG 27 April 1970 [30 Jan 1969] 5258/69 Heading B3F [Also in Divisions C3 and H1] In a casting process wherein a gasifiable pattern is embedded in a magnetizable moulding material, and in which the moulding material is subjected to a magnetic field before, during and possibly after pouring, the gasifiable pattern is coated prior to its incorporation in the moulding material with a composition comprising a particulate magnetizable material and a particulate refractory material dispersed in a liquid medium. The composition also preferably contains a resin or gum binding agent.
