Abstract

The invention provides a vacuum skull furnace. The vacuum skull furnace comprises a smelting chamber, a pouring chamber, a pouring funnel and a pouring valve; the smelting chamber is provided with a graphite crucible, a sensing coil, a crucible tipping mechanism, a first gas exhausting pipe, a first vacuum degree detecting device, an argon inflating pipe and a first gas pressure detecting device; the pouring chamber is provided with a mould shell, a centrifugal turntable, a lifting table, a second gas exhausting pipe, a second vacuum degree detecting device, an inflating pipe and a second gas pressure detecting device; the pouring funnel serves as a channel for the graphite crucible to pour a molten metal to the mould shell; the upper opening of the funnel is arranged in the smelting chamber and is matched with the graphite crucible; and the lower opening of the funnel is arranged in the pouring chamber and is matched with the mould shell. The invention also provides a working process of the vacuum skull furnace. The vacuum skull furnace can realize pressure pouring and centrifugal pouring simultaneously; and the pouring quality is greatly improved.

Description

technical field [0001] The invention relates to a vacuum shell solidification furnace and its working process. Background technique [0002] The smelting and pouring of titanium and its alloys are generally carried out in vacuum shell solidification furnaces, and vacuum shell solidification furnaces generally use centrifugal casting, but the pouring quality of centrifugal casting also needs to be improved. Contents of the invention [0003] The object of the present invention is to provide a vacuum shell solidification furnace and its working process, which can realize pressure casting and centrifugal casting at the same time, and greatly improve the pouring quality. [0004] To achieve the above object, the present invention provides a vacuum shell solidification furnace, comprising: [0005] melting chamber, [0006] The graphite crucible installed in the melting chamber, the induction coil installed in the melting chamber for induction heating of the graphite crucible...
