Abstract
The utility model discloses a boat for preparing high pure nano-powder, which is mainly formed by the lamination of a plurality of layers of boats. The utility model is characterized in that the middle upper parts of both sides of the boat at the upper layer are provided with six supporting points; the positions of the middle upper parts of both sides of the boat at the middle layer corresponding to the supporting points of the boat at the upper layer are provided with six supporting points; the frame face of the boat corresponding to the supporting points is provided with six positioning supporting points; the positions on the frame face of the boat at the lower layer corresponding to the supporting points of the boat at the middle layer are provided with six position supporting points. The utility model has the advantage of artful design, solves the problem in the prior art that a circular multi-tube furnace is made of common raw materials and can not produce superfine and nano metal tungsten powder. According to fluid mechanics principle, the stress of the end face and a high temperature deformation factor of 1000 DEG in the process of boat push are adequately considered, and thus, the utility model has industrial utility value.
Description
Technical field
The utility model belongs to the powder metallurgical technique technical field.
Background technology
The relative immediate similar prior art situation of the utility model: produce the tungsten powder in the metallurgy industry, adopt individual layer or double-deck boat at present usually.Its existing boat all is difficult to produce≤metal tungsten powder of 0.5 μ m, and existing boat weight 〉=9kg, increased and push away the boat difficulty and also wasted heating power.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can effectively overcome above-mentioned defective, solves three layers of boat stepped construction reasonability, makes air-flow distribute rationally a whole set of weight＜9kg; Reach energy-conservation, simple, effective, firm combination; But thereby the process matched therewith heavy industrialization, utilize circular multitube reduction furnace at low cost, produce high-quality high-purity nm tungsten powder.Technical solutions of the utility model are, a kind of boat for preparing high purity nanometer grade powder mainly is made up of the stack of multilayer boat, and it is characterized in that: middle and upper part, upper strata boat two limit is provided with 6 strong points; Middle and upper part, middle level boat two limit, corresponding upper strata boat supporting point position are provided with 6 strong points; On the boat frame face of the corresponding strong point 6 positioning supports points are set; On lower floor's boat frame face, corresponding middle level boat supporting point position, 6 positioning supports points are set.Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, solved in the prior art, circular multi-tube furnace uses common raw material, can not produce problem ultra-fine and the nano level metal tungsten powder.According to fluid mechanics principle, it is stressed to take into full account the end face that pushes away in the boat process, 1000 ℃ of high temperature deformation factors, tool industrial utilization.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of upper strata boat.
Fig. 2 is the structural representation of middle level boat.
Fig. 3 is the structural representation of lower floor's boat.
Fig. 4 is the overall structure schematic diagram after the boat stack.
The specific embodiment
Among the figure, boat structure: 6 strong points 11 are set in middle and upper part, upper strata boat 10 both sides; Middle and upper part, middle level boat 20 2 limit, corresponding upper strata boat supporting point position are provided with 6 strong points 21 equally, and 6 positioning supports points 22 (being used for supporting and limiting fixedly upper strata boat) are set on the boat frame face of the corresponding strong point; On lower floor's boat 30 frame faces, corresponding middle level boat supporting point position, 6 strong points 31 (be used for supporting with restriction fixedly middle level boat) are set, the bottom is provided with two band circular arc slip muscle parallel with the limit (being used for the load-bearing of a whole set of boat and the work of multi-tube furnace slides); A whole set of boat adopts Cr30Ni10 master's material+additive, and the high temperature hot investment casting forms; The distribution of weight of its three layers of boats is---upper strata: middle level: lower floor=1: 1.238: 1.952; Effective floor space ratio of three layers of boat is---upper strata: middle level: lower floor=1: 1.305: 1.691; A whole set of boat weight is 8.8kg.
