摘要： An insulated cold retort or hearth for producing refined metal from raw metal contaminated with high density inclusions and/or hard alpha particles. The hearth has a hollowed body with a rectangular bottom wall and respective upstanding rectangular side and end walls which have imbedded water pipes for cooling water to circulate. An upwardly open chamber is defined within the body which terminates at an upper rim for holding a skull of metal formed on the cooled walls of the hearth. A plurality of insulating panels are closely received in the chamber covering those areas of the inner surface where heat retention is desired. Alternatively, an insulating inner liner may be utilized which is closely received in the chamber covering part or all of the inner surface to prevent heat transfer between the skull and the cooled retort/hearth interior surface and retain heat within the skull. The liner has an interior surface which defines a skull-receiving sub-chamber sized to closely receive the skull therewithin. A sub-liner may be used which fits within the liner to further prevent heat transfer between the skull and the cooled interior surface and retain heat within the skull.

摘要： A seal for a continuous casting furnace having a melting chamber with a mold therein for producing a metal cast includes a passage between the melting chamber and external atmosphere. As the cast moves through the passage, the cast outer surface and the passage inner surface define therebetween a reservoir for containing liquid glass or other molten material to prevent the external atmosphere from entering the melting chamber. Particulate material fed into the reservoir is melted by heat from the cast to form the molten material. The molten material coats the cast as it moves through the passage and solidifies to form a coating to protect the hot cast from reacting with the external atmosphere. Preferably, the mold has an inner surface with a cross-sectional shape to define a cross-sectional shape of the cast outer surface whereby these cross-sectional shapes are substantially the same as a cross-sectional shape of the passage inner surface.
