Embodiment
Below in conjunction with accompanying drawing the preferred embodiment that is used for the alloying device of magnesium-rare earth melting of the present utility model is elaborated.
Alloying device of the present utility model can be used for any solid-liquid reaction, and obtains the melting reaction of liquid.
Be changed to example with the makeup of magnesium-rare earth molten alloy, in the alloying device synoptic diagram of the present utility model, brand-new design and the alloying device that is exclusively used in the magnesium-rare earth melting that produces, on its stir shaft 1, as stirring rake the same, the bottom is provided with a plurality of blades 3, and the upper fixed of blade has netted container parts, and this netted container parts comprises one or more netted containers 2.
But netted container 2 top openings are convenient to reaction raw materials and are packed into, and reaction raw materials all can move downward by action of gravity, finally flows into crucible bottom.
The material of netted container 2 is a titanium alloy, preferably adopts high temperature resistant titanium alloy, and reason is that it is difficult for reacting with rare earth element.
The aperture size of netted container 2 is less than the particle diameter of rare earths material, and for example rare earths material utilizes the shears of aperture 1cm to shear, and it is 6～8mm that so netted container should be provided with the aperture.
As a kind of concrete embodiment, this netted container parts only comprises a netted container 2 (as shown in Figure 1), the bottom of this netted container 2 is passed stir shaft 1 and is fixed on the stir shaft 1 so, netted container 2 then should use same material with stir shaft, be titanium alloy material, preferred high temperature resistant titanium alloy material.
As a kind of concrete embodiment, this netted container parts comprises a plurality of netted containers 2 (as shown in Figure 2), netted container 2 is fixed on around the stir shaft by the connecting arm on the stir shaft 14, example netted container parts as shown in Figures 2 and 3 comprises four netted containers 2, then utilizes four connecting arms, the 4 fixedly connected described netted containers 2 that are weldingly fixed on the stir shaft 1.
No matter be embodiment a plurality of netted containers 2 or single netted container 2, consider that the fixedly connected of same material is easier to, all material also can be selected titanium alloy, preferred high temperature resistant titanium alloy material comprises stir shaft 1, blade 3, netted container 2, connecting arm 4.
During the magnesium-rare earth melting reaction, rare earth in the alloy material is added in the netted container 2, because the netted container 2 of titanium alloy material is separated rare earth element and magnesium elements, so just avoided in the fusion process of magnesium-rare earth, the metallic impurity in crucible and the stirring rake being introduced rare earth element, guarantee alloying fully and avoid the introducing of impurity element, thereby obtain the component homogeneous, the sufficient high-quality magnesium-rare earth product of alloying.Just between the fusing point of the alloy of the fusing point of rare earth element and rare earth magnesium, 700～850 ℃, promptly the rare earth element before the melting reaction is a solid to smelting temperature, magnesium elements is a liquid, convenient fully contact, and the magnesium-rare earth after the melting is a liquid, can flow out netted container and enter in the crucible.
Magnesium-rare earth comprises magnesium-rare earth and rare earth magnesium zirconium alloy, rare earth element can be selected from the rare earth element that can form alloy arbitrarily with magnesium, cerium magnesium zirconium ternary alloy for example, WE is that heat-resistant rare earth magnesium is used alloy (neodymium, yttrium and zirconium), lanthanum magnesium master alloy, magnesium gadolinium zirconium ternary alloy, wherein, the zirconium raw material is in rare earths material places the netted container of titanium alloy material.
Embodiment:
When carrying out the magnesium-rare earth melting with this alloying device, the cylindraceous netted container 2 that a diameter is 800mm will be had on the stir shaft as shown in Figure 1, the stirring rake of two groups of blades 3, placing diameter is the central position embedding placement of the iron crucible of 1000mm, crucible is burnt to 700 ℃, in crucible, add solid metal magnesium and be molten into liquid state, netted container 2 is by high temperature resistant titanium alloy (T4 titanium alloy, Baoji Titanium Industry Co., Ltd.) makes, upper opening, add solid metal cerium and metal zirconium therein, melting reaction is carried out in stirring, and the reaction back produces liquid cerium magnesium zirconium ternary alloy.
Need to prove that at last the above only is preferred embodiment of the present utility model, rather than to the qualification of technical solutions of the utility model, any to of the present utility model do be equal to replacement, still in protection domain of the present utility model.
