Description
Technical field
The invention belongs to metal material processing fields, and in particular to a kind of pure nickel silk material short route preparation process.
Background technique
Pure nickel silk material is mainly for the manufacture of cathode for electron tube, anode grid side rod, pipe needle etc..With preferable mechanical performance
With the resistance to corrosion to alkali, such as sodium oxyhydroxide.Also with preferable electricity, hot, magnetic force controlling feature.Using
Range includes food and synthetic fibers processing, heat exchanger and chemistry, power industry.Typically there are manufacture resistance thermometer, electricity
Sub- pipe inner body, such as grid side rod, strut and electron tube exterior part, such as lead-out wire.The existing production technology of pure nickel silk material:
Mainly using vacuum induction melting, → ingot casting strips off the skin → is forged that → reconditioning → is rolled for the production for pure nickel silk material domestic at present
System → drawing, adopts this method that production process is various, and production cost is higher, and product delivery cycle is long.The side in forging process
Base surface be easy to appear visible crack, pipe, corner, step, it is rough and uneven in surface the defects of, in order to eliminate drawbacks described above, reconditioning work
Sequence needs to carry out a series of reconditioning to square billet, is easy to produce a large amount of metallic dust, and segmental defect needs to carry out artificial reconditioning,
Cause worker laboring environment poor, production efficiency is low, increases metal loss.
Summary of the invention
That it is an object of the present invention to provide a kind of process flows is short, cost is relatively low and the higher pure nickel silk material preparation process of efficiency.
The pure nickel silk material for meeting national standard GB/T21653-2008 technical parameters and performance requirement can be produced using the preparation process.
The technical scheme is that a kind of pure nickel silk material short route preparation process, includes the following steps:
1) vacuum induction melting: using electrolytic nickel for raw material, after ball milling, through vacuum medium frequency induction furnace melting；Then using true
The lower pouring technology of sky, obtains pure nickel billet；
2) billet figuring of surface: automatic grinding is carried out to the pure nickel billet that step 1) obtains using cylindrical grinder, removes pit, oxygen
Change the defect of skin；
3) billet heats: the billet after reconditioning being heated, 980~1050 DEG C of heating temperature, keeps the temperature 0.5-1.0 hours；
4) cogging hot rolling: cogging is carried out using reversible hot rolling mill to billet after the heating of step 3), and is rolled using tandem mill
At disk circle；
5) drawing: multi pass drawing is carried out using straight drawing machine to the disk circle of step 4), is drawn as requirement up to specification
Silk material.
The method have the benefit that: 1) present invention use vacuum melting+hot rolling+drawing process, directly produces pure
Nickel wire material carries out a series of add before not needing rolling square billet without hot forging (i.e. compared with the existing technology, omitting forging step)
Work processing, such as plane milling and reconditioning square billet, significantly reduce production cost, and process is few, high-efficient, with short production cycle.
2) present invention eliminates hot forging process link, the lumber recovery of product improves 8%-10%.
3) present invention is hot-forged the production link of square billet due to not having, and vacuum Round Billet material surface quality is good, and being not in can
See crackle, pipe, corner, step, it is rough and uneven in surface the defects of, ensure that subsequent rolling disk is round and silk material capability and performance.
4) the pure nickel N6 silk material (soft state) of present invention process preparation is 396-460Mpa, elongation percentage through detection tensile strength
For 35-37.5%, it is better than or is equivalent to the pure nickel silk material performance of prior art production.
