Description
Technical field
The present invention relates to high temperature alloy technology of preparing, and in particular to one kind prepares K403 castings using IC6 reverts
The method of high temperature alloy, the method that K403 cast superalloys are prepared especially with IC6 reverts.
Background technology
K403 alloys are a kind of Ni-based precipitation strength type equiax crystal cast superalloys, and the alloy is strong with higher high temperature
Degree, enduring quality and good castability.Due to being free of the precious metal element such as Hf, Ta in alloy, and Co contents are only 4.5%
~6.0%, therefore there is the relatively low cost of raw material.From the invention so far, which is used widely, available for making
Make a variety of aero-turbine rotor blades and guide vane, and the precision castings of other shapes complexity.
IC6 alloys are the directional solidification cylindrulite high temperature alloys using Ni3Al as base, the alloy have component is simple, cost is low,
The features such as density is small, just fusing point is high, is first, China intermetallic compound high-temperature material for being used for aero-engine, suitable for system
Make the turborotor of less than 1150 DEG C work.Blade production quantity is very big during 2000~2009, but efficiently uses
Rate only has 20%~30%, thereby produces substantial amounts of return and expects, such as running channel, riser, waste casting.Sent out recently as aviation
The development of motivation turbo blade material, the alloy are substituted by other alloys, and returning to material can only degrade use, thus cause
Problems with：
(1) K403 alloys still have wilderness demand at this stage as blade of aviation engine and thermal structure part, and often
Since the shortages of raw materials such as Ni, Mo can not complete delivery task；
(2) it cannot make the best use of everything, cause big containing precious metal elements such as substantial amounts of Ni, Mo in IC6 reverts
Measure the idle of resource and waste.
When running channel, riser, waste casting are as material recycling is returned, its shortcoming has at 2 points：First, return material is in irregular shape, such as
It is bad that fruit is directly placed into the too big electric conductivity of melting intermediate gap in crucible, so as to cause vaccum sensitive stove can not power transmission.Second, return
A certain number of refractory materials, such as filter screen, resistance to guncotton may be carried above feed back.The main component of these refractory materials is
Al2O3, MgO, SiO2 etc., to ensure the degree of purity of melting molten steel, it is necessary to remove it.
The content of the invention
Goal of the invention：It is an object of the invention to provide a kind of side that K403 cast superalloys are prepared using IC6 alloys
Method, main aspect are to solve the problems, such as K403 alloys since material shortage influences manufacturing schedule, and the accidental IC6 that would sit idle for is closed
Gold returns to material and is used, and reduces warehousing pressure, reduces energy consumption, reduces production cost.
Technical scheme：A kind of method that K403 cast superalloys are prepared using IC6 alloys is provided, including such as
Lower step：
Step 1, the cutting of IC6 alloys and purified treatment

Hour, surface blast is carried out after barreling processing to IC6 alloys, then IC6 alloy surfaces is blown off with dry compressed air；It is preferred that
It is that IC6 alloys length is less than 20cm after cutting；
Step 2, melting and ingot casting
IC6 alloys after step 1 is handled are fitted into vaccum sensitive stove crucible, power transmission vacuum≤5Pa, after alloying is clear
Heating starts to refine when reaching 1540~1560 DEG C, and refining power is 120~200kw, and refining time is 20~30min, refining
After the completion of stir 5~8min, cool down after sample using ceramic sampler in liquation, when temperature for 1480~1520 DEG C when, together
When adjust vacuum to start during below 10Pa pour into a mould ingot casting；Preferably use 2 tons or 4 tons of vaccum sensitive stoves；
Step 3, chemical composition analysis.
Chemical composition analysis is carried out to materialsing in step 2, obtains the ratio of every element in the IC6 alloys of ingot casting
Example, according to the component of the ratio of acquisition, the weight of ingot casting and K403 alloys, calculates each element filler for preparing K403 alloys
Weight；
Step 4, element adjustment
High-melting-point filler (C material, Ni material, Co material, Cr material, W expect) in element required after calculating is put into togerther crucible
Middle carry out melting, power transmission vacuum≤5Pa, alloying start to refine when heating reaches 1480~1520 DEG C afterwards clearly, refine power
120~200kw, refining time are 40~60min, and refining time cools down when reaching 35~45min to be added after molten surface conjunctiva
Enter Al material, Ti material, B material and Zr material, until completely melted, add Ce element fillers, stir 5~10min；It is eventually adding IC6 conjunctions
Golden ingot casting, 1430~1470 DEG C are warming up to after being stirred evenly after all fillers are completely melt, so that vacuum exists after heating
Below 10Pa carries out cast ingot casting.
Beneficial effect
(1) adding proportion that material is returned in the present invention is up to more than 1/3rd, and wherein Mo elements are integrally incorporated in return
In material, added without extra, efficiently solve the idle problem that IC6 alloys largely return to material；
(2) since IC6 alloys differ nearly 80 DEG C with the fusing point of K403 alloys, the present invention carries out alloy smelting process parameter
Probe boldly and adjust, have for high temperature alloy smelting technology and use for reference and directive significance；
(3) present invention realizes the recycling of precious metal element Ni, Mo, reduces the waste of nonrenewable resources,
Produce K403 alloys per ton and save production cost up to 100,000 yuan.
