Description
Technical field
The present invention relates to a kind of aluminium nitride nickelalloy and production method thereof.
Background technology
As everyone knows, nickel is the element strongly forming austenite and expand austenitic area, in producing stainless steel process, nickel is generally must one of added elements, and from 5%-12% not etc., but nickel is rare noble metal to add-on, single use metallic nickel in producing stainless steel process, production cost will be very high.Nitrogen is strong austenite former, nitrogen extensively exists in an atmosphere, cost is extremely low, but add nitrogen in stainless steel at present and take nitrogen flushing technique, the recovery rate of nitrogen can not precisely control, and stainless steel quality is stable not, so the mode adding nitrogenized manganese is at present in the majority, but the price of nitrogenized manganese is also very high at present, and production cost is also very high, it is also stable not with the recombine of steel in molten steel to add rear nitrogen.Therefore, studying aluminium nitride nickelalloy and the production method thereof of the low replacement metallic nickel of a kind of price and nitrogenized manganese, is the current technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of aluminium nitride nickelalloy and production method thereof.
The product technology scheme that the present invention solves its technical problem is:
Aluminium nitride nickelalloy, is characterized in that, its composition is: the nickel of 15-80%, the aluminium of 13-65%, the nitrogen of 5-25%, carbon≤0.5, sulphur≤0.01%, phosphorus≤0.01%.
The first method technical scheme that the present invention solves its technical problem is:
The production method of aluminium nitride nickelalloy, its processing step is: 1. raw material preparation-according to nickel in the composition of aluminium nitride nickelalloy, the grade of the content of aluminium and nitrogen and nickel powder and aluminium powder, calculate the consumption of nickel powder and aluminium powder, 2. batch mixing-the nickel powder of weighing and aluminium powder are mixed, 3. processing fire-first the even nickel powder of mixing and aluminium powder are put into autoclave addition point gunpowder silica flour, again reactor closed and be evacuated to-0.09MPa, then pass into nitrogenous gas to reactor and pressure is adjusted to 4-12MPa, finally be energized igniting, treat that dropping to less than 100 DEG C containing question response temperature in nitrogen pressure situation from vertex comes out of the stove tieing up.Described nickel powder is metallic nickel powder, and described nitrogenous gas is nitrogen, ammonia.The preferred pure nickel powder of metallic nickel powder; And the granularity of pure nickel powder and aluminium powder is 60-200 order.
The second method technical scheme that the present invention solves its technical problem is:
The production method of aluminium nitride nickelalloy, its processing step is: 1. raw material preparation-according to nickel in the composition of aluminium nitride nickelalloy, the grade of the content of aluminium and nitrogen and nickel powder and aluminium powder, calculate the consumption of metal nickel powder and aluminium powder, 2. batch mixing-the nickel powder of weighing and aluminium powder are mixed, 3. processing fire-the even powder of mixing is maybe pressed into ball by the even powder of mixing and kiln put into by dried moulding mixture, again reactor closed and be evacuated to-0.01MPa, then in reactor, pass into nitrogenous gas and pressure is adjusted to 0.01-0.04MPa, 4 hours are incubated after being warming up to 300-350 DEG C, 2 hours are incubated after continuing to be warming up to 550-650 DEG C again, be cooled to room stove subsequently to come out of the stove.Described nickel powder is metallic nickel powder, and described nitrogenous gas is nitrogen, ammonia; The preferred ferronickel powder of metallic nickel powder; And the granularity of ferronickel powder and aluminium powder is 60-300 order.Described pressure ball drying is at 110-160 DEG C of dry 4-10 hour in drying baker by wet bulb.
Compared with prior art, because nitrogen element partly can replace nickel in austenitic stainless steel, so add the consumption that aluminium nitride nickel can reduce nickel in stainless steel, thus reduce stainless steel production cost.Directly coordinate aluminium to carry out nitrogenize use in nickel, nitrogen content is high, and recovery rate is stablized, and directly can reduce the consumption of nickel and nitrogenized manganese, thus can effectively save cost, improves and stablize stainless performance.
