Abstract
The invention discloses the manufacture method of a kind of Cu compo pipe, be characterized in: founding CuCrY alloy, after obtaining ingot casting, take tempering heating centering perforation tubulation even wall aligning sizing low temperature destressing inspection protective packaging to put in storage and i.e. obtain CuCrY compo pipe.The present invention solve existing vacuum casting technique produce present in complex process, production cost is too high, production efficiency is low problem, there is the highest use value, thus more can be valued by Ge great production firm.
Description
Technical field
The present invention relates to the manufacture method of a kind of copper alloy tube, belong to smelting copper alloy tubulation field.
Background technology
CuCrY alloy belongs to sedimentation type hardening copper alloy, has high intensity, high conductivity, high softening temperature
Deng excellent combination property, it is mainly used in making the electrode of automatic arc welding, integrated circuit frame material, electricity
Gasification railway locomotive slip, large cast steel crystallization equipment, anticorrosion pipeline etc., its market potential is very big,
This alloy material of founding is then the first work producing this alloy material (wire rod, bar, sheet material etc.)
Sequence.
Copper alloy tube chromium-zirconium-copper material, lot of domestic and foreign producer develops the most, and acquirement preferably makes
By effect, cross copper amount and there has also been certain amplitude raising；But currently also there is certain weak point, predominantly:
Owing to alloying element there are still scaling loss in various degree in fusion process, cause the final alloying element of control
Content range is wider, and causes final products performance inconsistency big；Although melting under the conditions of high vacuum, alloy
Element also has certain oxidation, and the oxidation machine meeting of the many alloying elements of melting intermediate alloy, and affects product
Conductivity, recrystallization temperature and other mechanical property；Use hot forging, hot rolling molding process, though warp is solid
Molten aging strengthening model, mechanical strength is improved, but product mechanical behavior under high temperature is the most not ideal enough, and copper ingot resists
Croop property is inadequate, and copper ingot is suitable for reading yielding, and impact is normal to be produced.
Summary of the invention
For the deficiencies in the prior art, an object of the present invention is to overcome above-mentioned existing production Technology
Present in not enough, it is provided that a kind of non-vacuum melting method of CuCrY alloy, i.e. in the environmental condition of nitrogen
Under, use electric induction furnace to carry out melting, and use the mode of direct chill casting to produce CuCrY alloy, go forward side by side
One step is manufactured into copper alloy tube, is used for substituting the most commonly used vacuum casting production technology, solves
Production cost of having determined is too high, production efficiency is low, product specification by the present situation of vacuum drying oven capacity limit, expand
The application of this alloy material and scope.
Concrete grammar is as follows:
One, the casting of blank:
(1), open sealing bell by cathode copper, high temperature resistant dose, intermediate alloy CuCr be by ratio of weight and the number of copies
96.05: 1.21: 2.25 in batches and time interval successively joins in induction furnace, rises after energising fusing 1.5h
Temperature is to 1430 DEG C so that it is be completely melt；
(2) the most by ratio of weight and the number of copies 0.49 adds intermediate alloy CuY, then is warming up to 1430 DEG C, treats the most molten
Pour into a mould after change, during cast, cover crystallizer with white carbon black, be poured and i.e. can obtain CuCrY alloy；
Above-mentioned steps 1) in, high temperature resistant dose is boron oxide and silicon dioxide, and ratio of weight and number is 2.4: 1.2；
Above-mentioned steps 1,2) in, the weight proportion of Cr is, the weight proportion of 1.4%, Y is: 0.15%., and covers
Good bell melts；
(3), in casting process, melt is carried out the sealing frock protected by smelting furnace by employing high pure nitrogen, from
Gate spool injects crystallizer through the protective cover being connected with protective gas, crystallizer is placed protective cover and with compound molten
The lubricant in crystallizer is made in agent；Wherein first it is passed through high pure nitrogen 4～18min, to drive sealing work before casting
Air in dress and gate spool and protective cover, and use protective gas to protect in casting process all the time,
Founding becomes ingot blank.
Two, ingot casting is taked tempering heating-centering-perforation tubulation-even wall-aligning-sizing-low temperature destressing-
Inspection-protection-packaging is put in storage and is i.e. obtained CuCrY compo pipe.
Can also refine as follows further:
When pouring into a mould a diameter of 120-265 ingot casting, poring rate is 1.3mm/s；
The temperature of tempering heating is 550-750 DEG C；
The temperature of low temperature destressing is 80-120 DEG C, and the mode of net bed bouncing vibration is taked in destressing.
One of outstanding advantages of the present invention: use special technique to be prepared for a kind of CuCrY alloy, goes forward side by side one
Step is prepared for copper alloy tube；Owing to using the copper alloy of this technique founding, it is possible to be greatly enhanced copper alloy tube
Every mechanical performance；
The two of outstanding advantages with for tubulation before, the technique that have employed a lonneal, significantly reduce
Tearing tendency during low temperature tubulation, simultaneously for have employed special low temperature destressing means after tubulation,
Make to manage in actual applications, decrease stress corrosion, further enhancing the performance of copper alloy tube.
