Description
Technical field
The invention belongs to metal material processing fields, and in particular to a kind of preparation method of high-purity nickel band.
Background technique
High-purity nickel band has the characteristics that fusing point is high, anti-corrosion, good mechanical property, is important feature in vacuum electron device
Material is mainly used for making the not high various molded parts of operating temperature, such as anode, partition, electrode support, radio,
The fields such as electric light source, machine-building, chemical industry are widely used.In process of production due to electrolytic nickel, crystal grain is all vertical panel
Face is accumulated, and coarse grains, brittleness is big, and traditional mode of production sheet nickel uses cathode copper flat production, intermediate hierarchical, and layer
There is electrolyte contamination trace in centre, can not directly be processed, traditional production technology are as follows: by electrolytic nickel carry out melting, forging,
Pickling, cold rolling, reducing atmosphere heat treatment, are finally made into finished product, due to being influenced by production cost and melting condition, usually contain
A certain number of impurity, this partial impurities are entered in molten steel by impurity in steelmaking process refractory material, raw material etc., and metal is formed
Or non-metallic inclusion, material purity is reduced, the physical property and requirement of band are affected.In melting and forging process
In, adherency and heating scaling loss because of metal bath will lead to the metal loss of 4-8%.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of high-purity nickel band, can be produced using the preparation method
With high-purity, impurity is few, resistivity is low, the high-purity nickel band of good conductivity, and productivity is high, and material loss is few, by
It is pure raw material, it can be achieved that recycling in material.
To meet above-mentioned purpose, the technical solution adopted by the present invention are as follows:
A kind of the step of preparation method of high-purity nickel band, the preparation method are as follows:
(1) shape processing will be cut off at sheet nickel edge became uneven, according to specific band demand by width and length
Degree is processed, and is guaranteed making full use of for whole sheet nickel width and length, is guaranteed that its thickness is uniform, avoid through following process
Since deflection difference is too big, plate Local Property is different；
(2) tissue treatment, the sheet nickel after processing is put into heat-treatment furnace and is heat-treated, and heat treatment temperature is
700-1050 DEG C, soaking time is 4-5 hours, is cooled to room temperature in furnace later；
(3) cold rolling is layered, and using big pony roll cold rolling demixing technology, big roller and small roller diameter difference are 0.5-1mm, mill speed
For 500-1000mm/min, make sheet nickel due to plastic processing hardening effect, occurs answering force stratification between two layers, it is final to roll
It is completely separable to two layers of sheet nickel；
(4) sheet nickel after cold rolling is heat-treated, heating temperature 900- by protective atmosphere heat treatment using hydrogen shield
1050 DEG C, soaking time is 2.5 hours, is cooled to room temperature in furnace later；
(5) cold rolling, cold rolling are processed into required using the cold rolling process of conventional nickel and nickel alloy strip material according to the demand of product
Thickness.
Preferably, the diameter range of the pony roll is 165-350mm.
Preferably, two layers of became uneven will be present after the cold rolling layering, it is unified cold according to subsequent production specification requirement
It is rolled to same thickness, is convenient for following process.
The invention has the benefit that
For the congenital existing intermediate hierarchical defect of sheet nickel in preparation method of the invention, i.e., among two layers existing for
The pollution problem that the impurity such as electrolyte are formed has carried out the processing of cold rolling demixing technology, so that the nickel plate band of production is with high purity, miscellaneous
Matter is few, resistivity is low, conducts electricity very well, and productivity of the invention is high, and material loss is few, can since material is pure raw material
It realizes and recycles.
