Description
Technical field
The utility model belongs to Advanced Equipment field, particularly relates to a kind of vacuum melting rapid hardening equipment；This equipment is permissible
For manufacturing rare earth permanent magnet rapid hardening alloy, fast quenching NdFeB permanet magnetic powder, metal soft Ci powder, vacuum rapid hardening alloy etc..
Background technology
Rare earth permanent-magnetic material, is more and more applied with the magnetic property that it is excellent, is widely used in the nuclear-magnetism of medical treatment
Resonance image-forming, computer hard disc driver, sound equipment, mobile phone etc.；With energy-conservation and low-carbon economy requirement, Nd-Fe-B rare-earth permanent magnet
Material starts again at auto parts and components, household electrical appliance, energy-conservation and control motor, hybrid vehicle, and field of wind power generation should
With.
Nineteen eighty-three, Japan Patent 1,622,492 and 2, first 137,496 disclose Nd-Fe-B rare earth permanent magnetic material, announces
The characteristic of Nd-Fe-B rare earth permanent magnetic material, composition and manufacture method, United States Patent (USP) US6,461,565, US6,491,765,
US6,537,385, US6,527,874, US5,645,651 also disclose that the manufacture method of Nd-Fe-B rare-earth permanent magnet.
The preparation method manufacturing the RE permanent magnetic alloy that Nd-Fe-B rare earth permanent magnetic material is used typically has two kinds, Yi Zhongshi
Alloy molten solution is injected in mould, then by making the ingot mould casting of alloy pig compared with Slow cooling.One is to melt alloy
Liquid is cast on the chill roll of rotation, forms the rapid hardening method of rapid hardening alloy thin band or thin slice after chilling.Crystalline substance due to rapid hardening alloy
Grain more fine uniform, and Nd-rich phase distribution is good, currently manufactured high performance rare earth permanent-magnetic material typically all uses rapid hardening method
Prepare RE permanent magnetic alloy.
United States Patent (USP) US7,585,378 and Chinese patent CN97,217,372.2, CN01,241,237.6 disclose dilute
The manufacture method of soil permanent magnet vacuum rapid hardening alloy, neodymium iron boron raw material is cast to tundish after crucible melting, overflows from tundish
Aluminium alloy by chill roll cooling rapid hardening form alloy sheet.
But in the existing above-mentioned vacuum melting strip casting manufacturing for rare earth permanent-magnetic material, generally by pure iron, boron
The rapid hardening alloy raw materials such as iron, rare earths material and other interpolation metals use disposable entrance crucible to carry out the mode of melting, this
Sample in fusion process it is possible that the phenomenon of the more valuable raw material at high temperature volatilization loss such as rare earth；In addition, greatly
Raw material is put into crucible in border by compression ring, rare earth material also can be made to aoxidize, add the slag making in melting.Above-mentioned factor affects
The utilization rate of precious metal material, causes a certain degree of waste.The vacuum melting that Ai Fake Co., Ltd. of Japan is produced
Rapid hardening furnace, although have employed the design of secondary charging, but its purpose is to be filled in crucible internal cause raw material in fusion process and melt
The stocking space changed and occur, reaches to increase the effect of batch, and unresolved precious alloy raw material at high temperature loses
And the problem that rare earths material melting slag making is serious.
On the other hand, owing to the material cost of rare earth permanent-magnetic material is higher, in industry, researching and developing recovery profit always
By the method for the rare earth permanent magnet spent materials such as rare earth permanent magnet substandard products and leftover pieces, in order to reduce the cost of raw material of rare earth permanent-magnetic material,
Save existing natural resources.Owing to the degree of oxidation in above-mentioned rare earth permanent magnet spent material is higher, if using these waste materials as molten
Refining raw material remelting utilize, can in fusion process, produce substantial amounts of slag, this difficult problem make remelting waste material technique receive restriction and
Cannot extensively apply.Therefore, the process of Japan's commonly used non-remelting of relevant enterprise recycles rare earth permanent magnet spent material.
For example, ZL99800997.0 and US6,149,861 disclose a kind of method recycling sintered NdFeB waste material, this side
In method, carry out to waste material pulverizing, pickling and drying, then calcium reduction process is carried out to this product, is derived from recycling
Raw material alloy powder, then regulated its one-tenth be grouped into by adding other alloy powders in this powder, and then manufacture and burn
Knot Nd-Fe-B permanent magnet material.ZL02800504.X and US7,056,393 discloses a kind of method utilizing sintered NdFeB substandard products,
In the method, use hydrogen decrepitation to carry out coarse crushing to sintered NdFeB substandard products, then make fine powder, then will be by substandard products
After the fine powder made mixes with the fine powder that normal proto material is made, make sintered Nd-Fe-B permanent magnet.Above-mentioned non-remelting profit
More complicated by the method for waste material not only operation, in addition it is also necessary to the alloy powder of preparation heterogeneity is allocated its composition and improves its burning
Knot ability, makes troubles to production process.Prior thing, in this waste material Application way, due to non-remelting, powder that waste material is made
In Mo, oxygen and other impurity contents are higher, make the magnetic property of the rare earth permanent-magnetic material thus made be severely impacted.
