Technologically, the present invention features that the alloy contains high smelting point oxide Y2O3 capable of thinning crystal size extremely and dispersing homogeneously in the matrix to raise the adhesion between the alloy matrix and the oxide film, antioxidant performance of the alloy and anticorrosive performance to smelted glass.
Description
Affiliated field
The invention belongs to the nickel-base alloy field.Mainly be applicable in high temperature oxidation and the high-temperature corrosion environment.
Background technology
Current, glass in all trades and professions the utmost point use widely, as glassware, electric light source, medicine, chemical industry, electronics etc.Because the manufacturing of glass needs the pyroprocess of 1500 ℃-900 ℃ of experience, thereby need some high-temperature components indispensably in glass production by being melted to moulding, especially in moulding process, need the high-temperature component of making by metallic substance with in a large number.The use temperature of these parts is 900-1300 ℃ and do not wait, and to the performance requriements of material: antioxidant property is good, and refractory melts glass corrosion and washes away, and thermal shock resistance is good, and the cold and hot working performance is good, does not pollute glass etc.
In the prior art, EP0303957A1 and US4063934 patent provide a kind of fire-resistant oxidation resistant alloy respectively, but the use temperature of closing≤1100 ℃.Do not satisfy the requirement that glass industry is produced.The nickel-base alloy that ZL 94102564.0 provides a kind of new resistance to high temperature oxidation and refractory to melt glass corrosion, it uses up to 1200 ℃, widely uses in glass industry.But be higher than under 1200 ℃ the temperature, because the recrystallization temperature of this alloy is low, the grain growth tendency is bigger, so cause the alloy intercrystalline fracture often, use temperature can only be limited to≤and 1200 ℃.Trace it to its cause, except recrystallization temperature was low, this alloy of Another reason had added RE (rare earth) 0.1-0.3%, mainly is that the rare earth segregation greatly reduces thermoplasticity, K
αThe characteristic X-ray photo finds out that obviously rare earth element is segregated on the crystal boundary of alloy, becomes the root of crystal orientation fracture.
And use high-boron-silicon glass in industries such as medicine, sun power, electric light source, chemical industry at present, these goods are when producing, the use temperature of its profiled part (as pillar, orifice ring, ventpipe) is up to 1200-1280 ℃, for this reason, these parts mainly adopt high alumina refractory and corundum preparation, only 13 days work-ing life at present, changed in promptly 13 days, and change once these parts, and need to stop production 10 hours, output, cost all are affected.Also have many other high-temperature components to be used in 1200-1300 ℃, also have similar heel as fire damper, ventpipe, chute etc.
Summary of the invention
The object of the present invention is to provide and a kind ofly can under the high temperature more than 1200 ℃, still have the good resistance to high temperature oxidation and the high-performance high-temperature nickel-base alloy of resistance to high temperature corrosion.
At above-mentioned purpose, main technical schemes of the present invention is on the basis of the described nickel-base alloy of ZL94102564.0, with rare earth oxide Y
2O
3Substitute rare earth element ce, and significantly improve its content, make Y simultaneously
2O
3Be uniformly distributed on the matrix as the dispersion-strengthened particle, in the hope of reaching the extremely purpose of crystal grain thinning, its mechanism is oxide compound particle Y
2O
3Crystal boundary migration and dislocation motion have been hindered.
The concrete chemical ingredients (weight %) of high-performance high-temperature nickel-base alloy of the present invention is Cr 20-35%, Cu 0.5-1.5%, C≤0.1%, Fe 0.05-2.0%, Y
2O
30.2-1.0%, surplus is Ni.
Find out that by this alloying constituent principal character of the present invention is exactly to add the higher rare earth oxide Y of content
2O
3Y
2O
3The main effect of rare earth oxide is exactly the height crystal grain thinning.Because Y
2O
3Be refractory oxide, tiny refractory oxide highly dispersed ground and being evenly distributed in the matrix makes that motions such as crystal boundary and dislocation are obstructed under the 1200-1280 ℃ of condition of high temperature, finally makes grain refining.Simultaneously, relevant studies show that, when the content of rare earth in the superalloy greater than 0.3% the time, can improve the adhesion property of alloy oxide film and alloy substrate in the high temperature life-time service greatly, and the crystal grain of refinement oxide film, dwindle internal stress between alloy substrate and the oxide film (because of the linear expansivity of oxide film more much smaller than alloy substrate) because Y
2O
3Grain size reach nano level, can be filled on alloy substrate and the interfacial oxide film because Cr
+++The cavity that ion produces to external diffusion makes the interface of alloy substrate and oxide film continue to keep steady state, promptly continues to keep the compactness and the adhesion property that continues to keep and improve alloy substrate and oxide film of oxide film, thereby improves the antioxidant property of alloy.
In the present invention, Ni-based itself just have the good high-temperature performance, adds The addition of C u, helps improving refractory and melt the glass corrosion performance.
In sum, the present invention not only has certain hot strength, also has excellent high-temperature oxidation resistance, can be used for 1200-1280 ℃ hot conditions.
The present invention can adopt the multiple production method production of alloy, as melting and casting forging method, powder metallurgy process.
Compared with prior art, the present invention has following advantage:
1, compares with the metallic substance that has now in the glass industry application, use temperature height of the present invention can reach 1200-1280 ℃, can satisfy the requirement of glass industry to high-temperature component fully, in comprising that high-boron-silicon glass is produced, work in the 1200-1280 ℃ of profiled part under the hot conditions.This be other alloy can not and.
2, compare with the high alumina refractory that glass industry is now adopted, the present invention has the advantage of long service life.When both were intending comparing test under the mould high-boron-silicon glass working condition as high-temperature component, only be 13 days the work-ing life of high alumina refractory parts, and be higher than 130 days the work-ing life of alloy component of the present invention.Be the former 10 times.And change the high alumina refractory parts one time, need to stop production 10 hours, change at least every year 28 times, adopt alloy of the present invention, annual only the need changed 3 times.Existing domestic more than 100 of this class glass material production line that have produced high-boron-silicon glass per year and reached 140,000 tons, and each the replacing stopped production 10 hours, 1.5 tons of lost units, 42 tons of output of annual minimizing reduce by 300,000 yuan of output values altogether, comprise that the economic benefit that other glass production (as bottle cylinder factory) is brought every year reaches 1.5 hundred million.In addition, alloy of the present invention can also be applied in other anti-corrosion, high temperature resistant environment, and the economic benefit of bringing is more considerable.
