Abstract

The invention relates to the technical field of smelting furnaces, and particularly relates to a high-frequency smelting device for high-temperature alloy preparation. The high-frequency smelting device comprises a smelting barrel, wherein a furnace lining is arranged in the smelting barrel; high-frequency induction coils are embedded in the inner side wall and the bottom wall of the furnace lining; a graphite crucible is arranged in the furnace lining; an edge is arranged on the upper end face of the graphite crucible; fixing blocks are arranged on the two side walls of the smelting barrel; the upper end faces of the fixing blocks are fixedly connected with supports; sliding grooves are formed in the vertical end faces, close to each other, of the supports; the horizontal lower end facesof the supports are fixedly connected with hydraulic rods; the lower ends of the hydraulic rods are fixedly connected with a furnace cover; a pressing block is arranged on the lower end face of the furnace cover, and is located over an opening of the graphite crucible; and a wiring sleeve is arranged at the lower end of the smelting barrel. High-frequency large current is led into the high-frequency induction coils, the graphite crucible is heated, the temperature of alloy is rapidly increased, the aim of heating and melting is achieved, the structure is simple, the heating speed is high, andenergy saving and environment friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of melting furnaces, in particular to a high-frequency melting device for preparing superalloys. Background technique [0002] The smelting furnace is a new type of high-efficiency energy-saving furnace developed according to the alloy smelting process. It can well meet the requirements of the aluminum smelting process: strict requirements on alloy composition, discontinuous production, and large single furnace capacity. It achieves reduced consumption, Reduce burning loss, improve product quality, reduce labor intensity, improve working conditions and increase production efficiency. It is suitable for intermittent operations, smelting with a lot of alloys and recycled materials. Existing smelting furnaces need to be smelted under high temperature and high pressure conditions, and the tight sealing of the furnace cover will cause the pressure in the furnace to drop sharply, and the alloy will not reach the m...
