Description
Technical field
The present invention relates to a kind of technology and equipment of producing continuously non-crystaline amorphous metal powder body material under gas shield or vacuum environment with cooling mode scale.
Background technology
Amorphous alloy material is a kind of material aggregation state between crystal and liquid, amorphous alloy is the material that is different from the completely isotropic of crystal alloy, there is high strength, high rigidity, high-ductility, excellent soft magnet performance, high corrosion-resistant and excellent electrical property, have good catalysis and hydrogen storage ability.Because amorphous alloy material has above advantage, the advanced person that it becomes the high-technology fields such as power electronics information applies material.
At present; also cannot produce amorphous powdered alloy by some conventional powder process methods such as atomizations according to existing technology; and the production method of conventional amorphous powdered alloy normally adopts the single roller quench under antivacuum or non-protective atmosphere environment, cannot form the production of the scale of high-quality non-crystalline material and serialization.Therefore high-quality amorphous powdered alloy production method and the equipment of developing a kind of scale and serialization are current problems in the urgent need to address.
Summary of the invention
The problem of can not scale serialization producing in order to overcome high-quality amorphous powdered alloy, the present invention has developed the technique of producing continuously non-crystaline amorphous metal powder body material under gas shield or vacuum environment with cooling mode scale.
The technical solution adopted for the present invention to solve the technical problems is: adopt vacuum unit that system is vacuumized; and adopt gas shield or vacuum environment co-continuous feed compartment to feed in raw material; after reinforced; by gas shield or the two induction smelting system master alloy meltings of vacuum; let slip a remark by middle heat packs and current limliting; alloy molten solution is poured into the quick cooling alloy roller apparatus of high-speed motion; be rapidly solidificated into non-crystaline amorphous metal; and under the effect of centrifugal force, be thrown into crusher in crushing and become amorphous powdered alloy, broken amorphous powdered alloy is collected into powder classification chamber again and carries out classification.
The invention has the beneficial effects as follows: the technology and equipment that provides a kind of scale to produce continuously high-quality non-crystaline amorphous metal powder body material, has solved the shortcoming that current high-quality amorphous powdered alloy can not industrial-scale production.And this technique is easy to continuous production, and production procedure easily operates, and process is easily controlled; and granularity control and the Accurate Classification that can realize non-crystaline amorphous metal powder body material, reduce production costs, and; this technique whole process using vacuum or gas shield, the amorphous powdered alloy purity of production is very high.
