Description
Technical field
The utility model relates to a kind of power metallurgy equipment, relates to a kind of ultrasonic homogeneous blender of multi-element metal powder for preparing polynary molybdenum-base alloy powder specifically.
Background technology
Metal molybdenum is a kind of rare precious metal, has the fusing point height, under hot conditions, still has higher intensity and hardness, still has outstanding features such as excellent electrical and thermal conductivity and good stable property, and application is very extensively listed in the strategic resource management by a lot of countries.But it is low that metal molybdenum also exists recrystallization temperature, and mechanical and physical performances such as tension, surrender, extension are relatively poor, material defectives such as saw lumber difficult forming.Progress along with scientific and technological level; The development test means are also constantly improved and are improved; People progressively sum up in the science production practices of powder metallurgy and find, in metal molybdenum, add some metallic element, particularly after adding rare earth element; The recrystallization temperature of metal molybdenum can be effectively improved, thereby the mechanical and physical performance of molybdenum group alloy material can be greatly improved.Therefore, in molybdenum base material, add other metallic element materials that are mixed suitable, just become a kind of important technical for preparing the molybdenum-base alloy powder in the powder metallurgical technology.
In molybdenum base material, add other metallic element materials that are mixed, process the control of molybdenum-base alloy powder requirement component accurately, homogeneous dispersion is abundant, and constituent element is evenly distributed, granule size standard, loose particles appropriateness.Current, the technical method that China prepares the molybdenum-base alloy powder mainly contains following three kinds:
The one, liquid/liquid mixed technology.The principal character of this technical method is: earlier molybdenum base materials such as ammonium molybdate or molybdenum oxide are processed concentration of dissolved liquid; Mix other metallic element oxides or the hydride dissolves liquid of apolegamy in proportion, carry out liquid/liquid dissolving homogeneous through the mechanical agitation method and be mixed; And then take traditional mode of production process such as reduction, oven dry, pulverizing, screening to process the molybdenum-base alloy powder.This technical method, simple, the characteristics such as equipment is common, formation scale easily that possess skills, can satisfy basically homogeneous dispersion fully, constituent element is evenly distributed, the specification requirement of granule size standard, loose particles appropriateness; Process route is long, problems such as use equipment is many, energy resource consumption is big, production cost height but this technical method also exists; Particularly exist major defects such as the production environment closure is poor, impurity element is sneaked into the probability height, component precision control difficulty, cause material capability uniformity, the stability of processing molybdenum group alloy material all relatively poor.
The 2nd, Gu liquid/mixed technology.The principal character of this technical method is: earlier molybdenum base materials such as ammonium molybdate or molybdenum oxide are processed concentration of dissolved liquid; Directly mix other metallic element oxides or the hydride powder of apolegamy in proportion, carry out liquid/solid solution through the mechanical agitation method and separate homogeneous and be mixed; And then take traditional mode of production process such as reduction, oven dry, pulverizing, screening to process the molybdenum-base alloy powder.This technical method, the characteristics that have and the defective of existence, basic similar with liquid/liquid mixed technology.
The 3rd, Gu Gu/mixed technology.The principal character of this technical method is: select pure molybdenum powder to do molybdenum base material; Directly in pure molybdenum powder, mix other elemental metals element powders or the elemental metals oxide powder of apolegamy in proportion, mix mechanical equipment through special use and carry out homogeneous dispersion and mix operation and process the molybdenum-base alloy powder.This technical method; The main special-purpose metal powder agitation mixer that relies on is realized; It is the general basic technology in the powder metallurgical technology; Possess skills ripe, easy to operate, production efficiency is high, the control of low cost of manufacture, component accurately, characteristics such as granule size standard, loose particles appropriateness, the metal powder agitation mixer of particularly developing out has in recent years been quoted the multiple advanced forms of motion that is mixed that stirs such as two dimensional motion, three-dimensional motion, double helix reciprocating motion; Making metal dust mix technical merit has had very fast development, and the homogeneous dispersion ability has also had bigger lifting.But; Because metal dusts such as the iron of using always in molybdenum-base alloy powder and the powder metallurgical technology, copper, aluminium, cobalt, nickel, titanium are different; Not only the powder size to all batching components all requires thinner; Generally all be no more than 4 μ m; And pure molybdenum powder self has big, the mobile characteristic such as relatively poor of reunion adhesion energy again, adds the molybdenum-base alloy powder overwhelming majority and all selects the group material ingredients technical that adopts the multi-element metal powder to be mixed, consolidate/the homogeneous dispersion stirring operation that is mixed Gu use existing metal dust to mix mechanical equipment; Be good at satisfying the specification requirement of polynary molybdenum-base alloy powder to the quality that is mixed, the molybdenum based multicomponent alloy material of processing also certainly exists material capability defectives such as uniformity, less stable.
The utility model general metal dust agitation mixer in fully researching and analysing the powder metallurgy industry exists on the basis of shortcoming or deficiency; To of the specification requirement of polynary molybdenum-base alloy powder to the quality that is mixed; Research and design goes out a kind ofly to spray the technology of mixing to advanced power ultrasonic homogeneous dispersion technology with traditional mechanical atomization and combine, can satisfy polynary molybdenum-base alloy powder to the quality that is mixed realize component control accurately, homogeneous dispersion fully, constituent element is evenly distributed, the ultrasonic homogeneous blender of multi-element metal powder of granule size standard, the requirement of loose particles appropriateness technical standard.
Summary of the invention
The technical problem that the utility model will solve:
