The advantage of aspect such as can utilize and especially noticeable.The Magnesium Alloys Components produced by methods such as casting are used extensively
In fields such as automobile, telecommunications, Aero-Space, weapons and commodity.Many defects of Mg alloy castings are because magnesium is closed
What gold solution brought, thus magnesium alloy melting and refining for reduce Mg alloy castings defect it is critical that operation.Magnesium
Alloy chemistry is more active, easily aoxidizes and burns, and forms loose oxide-film in magnesium alloy solution surface.At present
Most enterprise is filled with SF in Melting Magnesium alloy process6Gas is protected to magnesium alloy solution, prevents magnesium alloy solution excessive
There is burning after-explosion with oxygen reaction.It is passed through inert gas after the completion of melting to be refined, inert gas is in the solution
Bubble is formed, the negative pressure brought using inert gas bubble is by the gas in solution and is mingled with and takes magnesium alloy solution surface to.
Cast after the completion of refining.Current melting and refining procedure are generally carried out separately, in refining process due to without
SF6The protection of gas can be easy to make magnesium alloy solution and oxygen reaction again, so as to have impact on the quality of magnesium alloy solution, and band
Carry out certain danger.
The content of the invention
The invention aims to provide a kind of melting and refining magnesium alloys cast composite crucible, tradition can be reached molten
Refining and the effect of refining magnesium alloys solution, while the adverse consequences caused by independent refining magnesium alloys solution can be eliminated again.
The object of the present invention is achieved like this：Including the crucible body being made up of sidewall of crucible, crucible bottom, crucible cover, institute
The middle cover that crucible cover is hinged including protecgulum and protecgulum and the bonnet that middle cover is hinged are stated, side ring, side are provided with the sidewall of crucible
Be provided with earrings on ring, it is described after cover and be provided with circulating line, circulating line be passed through SF6The gas feeding pipe connection of gas,
Sidewall of crucible upper end is provided with pouring mouth, and ventilating agitator is additionally provided with the crucible cover, and the lower end of ventilating agitator is located at crucible
Pars intramuralis.
Present invention additionally comprises such some architectural features：
1. dual-layered baffle plate is additionally provided with sidewall of crucible described in, and the upper end of dual-layered baffle plate passes through inverted L shape fixture and crucible
Wall is connected.
2. covered after crucible cover and be symmetrically arranged with suspension ring.
Compared with prior art, the beneficial effects of the invention are as follows：Crucible can be made to form confined space in fusion process
Significantly more efficient utilization SF6Gas carries out melting, while can also be carried out in argon gas protection in refining, effectively protects essence
Magnesium alloy solution during refining.The melting and refining cast are simple to operate with composite crucible, convenient dismounting, are conducive to obtaining Functionality, quality and appealing design
Different magnesium alloy solution.

Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment one：According to Fig. 1-4, the utility model includes sidewall of crucible 1, crucible bottom 2, pouring mouth 3, side ring 4, earrings
5th, crucible cover 6, fixing device 7, hinge 8, suspension ring 9, circulating line 10, gas feeding pipe 11, ventilating agitator 12.Sidewall of crucible 1 is thick
After 10-15mm is rolled by the 20Mn steel plates of inner-layer thick 8-12mm and the 0Cr13Ni9Ti blast weldering clad steel plates of outer thickness 1-3mm
It is welded, it is highly 700-1000mm, and top diameter is 500-700mm, and base diameter is 450-650mm.Crucible bottom is straight
Footpath is stamped to form for the circular clad steel plate of 450-600mm, and clad steel plate is by 1-3mm thick 0Cr13Ni9Ti steel plates and 17-
19mm thick 20Mn steel plates blast weldering is composited.Sidewall of crucible 1 forms overall with crucible bottom 2 by welding.The 100- long of pouring mouth 3
120mm 170-190mm wide, are linked together by way of welding with sidewall of crucible 1.The internal diameter 450-650mm external diameters 650- of side ring 4
850mm, thickness is 15-30mm, is welded at crucible top 130mm.There are two earrings 5 on side ring 4, its 96mm long,
110mm high, thick 30mm, wherein center portion position have the centre bore of an a diameter of 50mm, earrings 5 is fixed by welding on side ring 4.
