Abstract

1,025,072. Casting-machines. ALLMANNA SVENSKA ELEKTRISKA A.B. Jan. 3, 1963 [Jan. 11, 1962], No. 346/63. Heading B3F. A casting apparatus comprises an inductive furnace 16, Figs. 1 and 2 (not shown), in a tiltable vacuum-tight tank 12, a gutter 14 for the degassed melt extending along the tilting axis, and a relatively movable casing 18 enclosing a mould 19, or the like, and connectible in gas-tight manner to the tank through a rotary seal 23. The tank 12 is sealed at the end of the gutter by a closure member 24, or a valve during evacuation of the tank degassing of the melt, and subsequent refilling of the tank with a protective gas atmosphere at a pressure above atmospheric and a throttling member such as a holded membrane or glass wool maintains the atmosphere in the tank when the lid 24 is removed for connection of the casing 18, the throttling means being subsequently carried away by the melt. The casing 18 may also be filled with a protective gas. With some melts, e.g. those of low C content air may be used instead'of a protective gas, the air being made oxygen poor, e.g. by the combustion of the oxygen. In a modification several moulds are mounted on a rotating table inside a casing.
