Description
Technical field
The present invention relates to alloy smelting technique, and in particular to a kind of vacuum metling work of the nickel-base alloy containing aluminium titanium boron zirconium
Skill.
Background technology
In the alloy that aviation is used, component typically all includes several low melting point elements such as aluminium, titanium, boron, zirconium.Adding this
, can if not controlling the factors such as opportunity, temperature, the vacuum of addition strictly when a little low melting point elements carry out Alloying Treatment
The larger scaling loss of generation and volatilization, are difficult to control to alloy composition, so as to produce waste product.Specifically, add aluminium, titanium,
Vacuum when boron, zirconium is too low or equipment leak rate is big, and substantial amounts of aluminium, titanium, boron, zr element can produce oxidization burning loss, and composition is difficult
To control.Molten metal temperature is too high when adding aluminium, titanium, and substantial amounts of aluminium, titanium can then be put due to heat release answers and produce scaling loss and wave
Hair.When adding aluminium, titanium into molten metal, violent exothermic reaction can be produced, during particularly with the addition of measuring larger, molten metal is put
Thermal response is just big.Molten metal proper temperature when even if aluminium, titanium are added, but addition is excessive due to one time, can equally produce burning
Damage and vacuum volatilization is difficult to control to alloy composition.
Aero-Space and civilian high-temperature alloy vacuum smelting when, it is necessary to strictly control alloy in gas content (oxygen,
Nitrogen, hydrogen), at present according to company standard, general oxygen, nitrogen content are typically in 20ppm or so in many alloys.
Further, since aluminium, titanium, boron, zirconium itself are lighter, density is small, after being added in molten metal, swims in metal and melts
Liquid surface, easily produces segregation, can have a strong impact on the combination property of alloy.Specifically, the addition time of boron is also extremely important,
It is too early to add, easily scaling loss, adds too late, easy skewness, therefore grasps the time of boron addition and just seem extremely important.
In view of the situation of currently available technology, needs badly and researches and develops a kind of vacuum metling work of the nickel-base alloy containing aluminium titanium boron zirconium
Skill.
The content of the invention
It is an object of the invention to provide a kind of chemical composition is more uniform, low melting point element scaling loss and volatilize less, alloy is held
The vacuum metling technique of long performance and the strong nickel-base alloy containing aluminium titanium boron zirconium of room temperature tensile properties.
The vacuum metling technique of nickel-base alloy of the present invention containing aluminium titanium boron zirconium, comprises the following steps：
(1) all elements added into vacuum drying oven crucible in the nickel-base alloy in addition to aluminium, titanium, boron, zirconium, nickel carry out smelting
Refining；
(2) 1370~1390 DEG C are cooled to, aluminium, titanium are added thereto, aluminium, titanium is warming up to and all melts；
(3) 1410~1430 DEG C of keeping temperature, add ni-b alloy, zirconium thereto, are warming up to ni-b alloy, zirconium all molten
Change, obtain molten metal；
(4) cool, freeze molten metal, when temperature is down to 1360~1380 DEG C, then when being warming up to 1450~1470 DEG C, enter
Row steel tapping casting.
Wherein：
1560~1580 DEG C of step (1) smelting temperature, 20~30min of the duration of heat.
Step (2) is warming up to after aluminium, titanium whole fusing, is stirred for 3~5min.
Step (3) is warming up to after ni-b alloy, zirconium whole fusing, is stirred for 3~5min.
Add vacuum≤0.1Pa when aluminium, titanium, ni-b alloy, zirconium.By controlling vacuum so that the chemistry of alloy
Composition is more uniform, and low melting point element scaling loss and volatilization are few.Boron should be added before the melting later stage, steel tapping casting.Aluminium, titanium are added
When measuring big, when general aluminium is 3wt.% or so, when titanium is 3wt.% or so, it should add twice in two batches or many batches of additions.
If being considered as adding more times during more aluminium Ti contents.
After step (4) freezing molten metal can be using having a power failure, the form of Temperature fall, it would however also be possible to employ other cooling shapes
Formula, the form of the present invention preferably power failure Temperature fall.
Beneficial effects of the present invention are as follows：
The present invention is by controlling aluminium, titanium, boron, zirconium to add opportunity and temperature so that the chemical composition of alloy is more uniform, low
Melting element scaling loss and volatilization are few；Molten metal is caused during cooling solidification, to be dissolved in gold using freezing molten metal
The pernicious gas belonged in liquation is floated, and the Negative Pressure Difference produced is smelted using vacuum drying oven and further excludes pernicious gas, is closed simultaneously
The chemical composition of gold is more uniform.The present invention improves the enduring quality and room temperature tensile properties of high temperature alloy, further pure
Molten metal, so as to obtain high-quality high temperature alloy.
Pernicious gas and the reduction of low-melting impurities content in molten metal of the present invention, alloy molten solution are pure, the change of alloy
Study point uniform, the comprehensive mechanical property and quality of alloy reach the level of domestic and international high duty alloy.
