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
The present invention relates to a kind of magnesium lithium alloy vacuum melting furnace, particularly a kind of split type magnesium lithium alloy vacuum melting furnace is used for the integrated melting of feeding in continuous material, vacuum melting, direct casting to magnesium lithium alloy.
Background technology
Magnesium lithium alloy melting raw material magnesium, lithium are extremely active metallic element, and high temperature exposure is rapid oxidation of meeting even combustion explosion in air, must be in melting under the vacuum environment, casting; Batching is put in the stove heating melting with the monomer-type smelting furnace and casting is all accomplished in a furnace chamber; The furnace chamber volume is big, and it is low to vacuumize efficient, and each stove melting vacuumizes and will take 50% smelting time; Cause production efficiency low, can't realize large-scale continuous production.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of this invention is to provide a kind of split type magnesium lithium alloy vacuum melting furnace, have the efficient of vacuumizing height, production efficiency height and the characteristics that realize large-scale production.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of split type magnesium lithium alloy vacuum melting furnace; Include one-level material loading stove, one-level material loading stove is connected with feed mechanism through the vacuum electromagnetic valve, feed mechanism with also be connected with the secondary smelting furnace; The secondary smelting furnace is connected with three grades of casting furnaces through the second vacuum electromagnetic valve, and secondary smelting furnace one side also links to each other with vacuum extractor.
Be provided with electromagnetic induction heater in the described secondary melting furnace chamber.
The invention has the beneficial effects as follows:
The present invention adopts three sections split type furnace cavity structures, and each furnace chamber vacuum of electromagnetic valve control has greatly shortened the pumpdown time, enhances productivity; The present invention operates one-level material loading furnace chamber, secondary melting furnace chamber or three grades of casting furnace chambers separately, because vacuum solenoid cuts out, other two furnace chambers still keep very high vacuum, after accomplishing blowing or getting material, only has the furnace chamber of working to have air to get into.Other two sections furnace chamber integral body still keep very high vacuum, therefore only need the short period can satisfy the demand that the next cycle vacuumizes, and have greatly shortened the pumpdown time.
Description of drawings
Accompanying drawing 1 is a structural principle sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Referring to accompanying drawing 1; A kind of split type magnesium lithium alloy vacuum melting furnace; Include one-level material loading stove 1, one-level material loading stove 1 is connected with feed mechanism 3 through vacuum electromagnetic valve 2, feed mechanism 3 with also be connected with secondary smelting furnace 4; Secondary smelting furnace 4 is connected with three grades of casting furnaces 6 through the second vacuum electromagnetic valve 5, and secondary smelting furnace 6 one sides also link to each other with vacuum extractor 7.
Be provided with electromagnetic induction heater 8 in described secondary smelting furnace 4 furnace chambers.
Operation principle of the present invention is:
The present invention utilizes the connected sum disjunction of each furnace chamber of vacuum solenoid gate control.During work, after vacuum extractor vacuumizes one-level material loading stove furnace chamber, secondary smelting furnace furnace chamber and three grades of casting furnace furnace chambers, with vacuum solenoid disjunction one-level material loading stove furnace chamber and secondary smelting furnace furnace chamber; The second vacuum solenoid disjunction secondary smelting furnace furnace chamber and three grades of casting furnace furnace chambers; One-level material loading stove furnace chamber, secondary smelting furnace furnace chamber and three grades of each self-sustainings of vacuum that the casting furnace furnace chamber is interior, material loading, melting, casting cycle are accomplished in one-level material loading stove furnace chamber, secondary smelting furnace furnace chamber and three grades of casting furnace furnace chambers respectively, like this after next melting cycle begins; No matter operate any one furnace chamber separately; Such as at material loading furnace chamber material loading or take out ingot casting, because closed electromagnetic valve, other two furnace chambers still keep very high vacuum; After accomplishing blowing or getting material, only in harness furnace chamber has air to get into.Smelting furnace integral body still keeps very high vacuum, only needs the short time can satisfy the demand that the next cycle vacuumizes, and has greatly shortened the pumpdown time, has improved production efficiency.
