990,512. Casting ingots. FUCHS G.m.b.H. April 13, 1964 [April 13, 1963], No. 15213/64. Heading B3F. In a method of casting a metal ingot, liquid metal which is to solidify is contained in a thin walled mould 2 which is provided with heating means 3 in the form of an electrical element or induction coil. The mould is progressively cooled vertically upwards from the bottom by permitting relative movement between the coolant bath 4 and the mould whilst the metal in the mould above the bath level is kept liquid by the heating means. The space above the metal in the mould may be maintained under vacuum or under pressure with an inert gas while solidification takes place.
