Description
Technical field
The present invention relates to the production method of the resonant rod invar cold-heading silk of radio-frequency (RF) device, meet the requirement of required hardness that resonant rod is suitable for and the coefficient of expansion, and material and the production method thereof of cold-heading processing can be met, especially about the improvement of the Ni-based 4J36 of expansion alloy material.
Background technology
Along with mobile communication business develop rapidly, radio-frequency (RF) device becomes product indispensable in the construction of communication base station, and applies to resonant rod product in a large number in radio-frequency (RF) device.Resonant rod is as the core component of radio-frequency (RF) device, bar is adopted to carry out lathe turning processing because its accuracy requirement is higher for many years, but in recent years along with domestic and international communications industry further develops the acceleration of cracking the international market with home communications primary device business, the market requirement of radio-frequency devices is increasing, and manufacture resonant rod at present and all adopt numerically-controlled machine (CNC) to carry out machining to resonant rod, therefore the problem brought is that work material waste is serious, material use efficiency only has 60% ~ 70%, and process period is longer, working (machining) efficiency is only 30 ~ 40/hour.The working (machining) efficiency of resonant rod becomes restriction client improving product output, reduces the obstacle of every cost.Find in the research and practice process of prior art: traditional cold-heading working method is mainly for the manufacture of parts such as bolt, nut, iron nail, rivet and steel balls.Forging stock material can be copper, aluminium, carbon steel, steel alloy, stainless steel and titanium alloy etc., and material use efficiency can reach 80 ~ 90%, not only increases working (machining) efficiency, more saves material, reduces cost of goods manifactured.And existing resonant rod material is owing to will meet the requirement of hardness and the coefficient of expansion, therefore it can not adopt cold-heading method to carry out simultaneous manufacturing.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of radio-frequency (RF) device
resonant rod is usedinvar
the production method of cold-heading silk, to obtainmeet the requirement of hardness needed for the resonant rod in radio-frequency (RF) device and the coefficient of expansion, the cold-heading silk of the requirement of cold-heading processing can be met simultaneously.
Inventive concept: suitably adjust original 4J36 expansion alloy material composition in GB allowed band, incorporate new production method.
For solving the problems of the technologies described above, 4J36 expansion alloy material selected by described cold-heading silk, and its each component comprised is (wt.% represents): nickel: 35-37%, manganese: 0.2-0.6%, silicon :≤0.3%, phosphorus :≤0.2%, carbon :≤0.05%, sulphur :≤0.02%, iron: surplus.
The production method of described cold-heading silk comprises the following steps: vacuum melting → esr → forge cogging → hot-roll forming → crin drawing → sour openpore material → polishing deburring → anneal → pickling test → cold drawn → thermal treatment, wherein:
1) vacuum melting: raw material Jinchuan Ni plate, Pure Silicon Metal, Mn, pure Fe are loaded after baking in the ZGHL0.25-250-1 type vacuum induction melting furnace of east, Jinzhou electric furnace company limited production and carry out melting, high-power high speed melt is added after melting 70% of total mass, when entering refining period after refining temperature 1460-1660 DEG C to be achieved after fine melt (preferably 1500 DEG C), refining keeps 30 minutes, and the refining later stage turns rough vacuum (10
3-10
-1pa), tapping in high-power stirring 1-3 minute, waters injecting electrode.
2) esr: be that the fluorite of 1:1 and titanium dioxide prepare striking agent with mass ratio, uses CaF
2, Al
2o
3make remelting electroslag system with CaO, wherein, the mass percent of three is: CaF
2: 65%-75%, Al
2o
3: 15%-25%, CaO: surplus; Shove charge, striking slag making, smelting, feeding, cooling, make steel ingot base; When adding slag, spoon does not allow to contact with crystallizer, electrode bar or slag charge on crystallizer disorderly smash by slag spoon simultaneously, striking electric current is 500-1500A, normally smelt again after slag fine melt, control electric current 2500-3000A, voltage 38-41V, make electrode melting, until crystallizer is filled, smelting finishes carries out feeding, the de-ingot air cooling of remelted ingot cooling.
Described vacuum metling operation and esr operation, the ZGHL0.25-250-1 type vacuum induction melting furnace used improves purity and the uniform texture of steel alloy effectively, improve the surface of steel ingot, inner quality, improve the performance of steel alloy, reduce further the generation of nonmetallic inclusionsin steel.
3) cogging is forged:
(1) preheating: steel ingot base is heated to 850 DEG C by room temperature, preheating 30-50 minute;
(2) heat up: be warmed up to 1050-1150 DEG C and turn over ingot blank, insulation 40-50 minute;
(3) be incubated: when reaching forging temperature, initial forging temperature >=1100 DEG C, final forging temperature >=950 DEG C.
(4) forging: adopt the second light industry bureau one weight, two uniform methodologys make steel ingot.
Described forging forges to start to touch with less deflection, improve rear bang of taking the circumstances into consideration etc. plasticity, touch again when closing on final forging temperature, require that distortion is even, avoid repeatedly clashing at same position, forge in process and want duty to stand up, diligent charging, it is wide that each inlet amount should be less than brill, be greater than draught, avoid producing hammering and folding, failure surface, affects the quality of cold heading steel.
4) hot-roll forming: material loads the temperature of annealing furnace :≤600 DEG C; Heating-up time >=120 minutes; Heating temperature: 1100-1150 DEG C; Soaking time: >=30 minutes, begins to roll temperature: >=1100 DEG C; Finishing temperature >=950 DEG C.
Above-mentioned hot-rolled process, enters stokehold and assembles production spare part and adjust, and can avoid producing folding in the operation of rolling or scratching, destroy product surface, form the crackle of cracking.
5) crin drawing: before operation, first carries out joining mould, carries out drawing process by deformation requirements glomerocryst mould.
Described crin drawing procedure, according to dimensional requirement, need select the mould of suitable pass, and it is as follows to join mold technique standard:
Unit (mm) " * " represents annealing (annealing temperature is see " well vacuum electric furnace thermal treatment (annealing) table look-up ")
￠ 18.0*-￠ 17.0*-￠ 16.0*-￠ 15.0*-￠ 14.0*-￠ 13.0*-￠ 10.0* and ￠ 8.5*
