Split magnesium-lithium alloy vacuum smelting furnace

Abstract

A split magnesium-lithium alloy vacuum smelting furnace comprises a primary material feeding furnace. The primary material feeding furnace is communicated with a material feeding mechanism through a vacuum electromagnetic valve, the material feeding mechanism is further communicated with a secondary smelting furnace, the secondary smelting furnace is communicated with a tertiary casting furnace through a second electromagnetic valve, and one side of the secondary smelting furnace is further connected with a vacuumizing device. After the vacuumizing device vacuumizes the primary material feeding furnace, the secondary smelting furnace and the tertiary casting furnace, the primary material feeding furnace and a secondary smelting furnace cavity are disconnected through the vacuum electromagnetic valve, the secondary smelting furnace cavity and a tertiary casting furnace cavity are disconnected through the second electromagnetic valve, vacuum degree in a primary material feeding furnace cavity, the secondary smelting furnace cavity and the tertiary casting furnace cavity is respectively kept, and material loading, smelting and casting processes are respectively finished in the primary material feeding furnace, the secondary smelting furnace and the tertiary casting furnace. The split magnesium-lithium alloy vacuum smelting furnace has the advantages of being high in vacuumizing efficiency and production efficiency and achieving large-scale production.

Description

technical field [0001] The invention relates to a magnesium-lithium alloy vacuum smelting furnace, in particular to a split-type magnesium-lithium alloy vacuum smelting furnace, which is used for continuous feeding, vacuum smelting, and continuous casting integrated smelting of the magnesium-lithium alloy. Background technique [0002] Magnesium-lithium alloy smelting raw materials Magnesium and lithium are extremely active metal elements. Exposure to high temperature in the air will quickly oxidize or even burn and explode. It must be smelted and cast in a vacuum environment. The single-body melting furnace puts the ingredients in the furnace to heat and melt The casting and casting are all completed in one furnace chamber, which has a large volume and low vacuuming efficiency. The vacuuming of each furnace takes up 50% of the melting time, resulting in low production efficiency and unable to achieve large-scale continuous production. Contents of the invention [0003] In...

Problems solved by technology

[0002] Magnesium-lithium alloy smelting raw materials Magnesium and lithium are extremely active metal elements. Exposure to high temperature in the air will quickly oxidize or even burn and explode. It must be smelted and cast in a vacuum environment. The single-body melting furnace puts the ingredients in the furnace for heating and melting The casting and casting are all completed in one furnace chamber. The furnace chamber is large in size and the vacuuming efficiency is low. The vacuuming of each furnace takes up 50% of the melting time, resulting in low production efficiency and unable to achieve large-scale continuous production.
