A kind of superalloy is cut the clean method of material
Technical field
The present invention relates to a kind of superalloy and cut the clean method of material.
Background technology
Superalloy is mainly for the manufacture of the high-temperature components such as turbine blade, turning vane, the turbine disk, hpc dish and combustion chamber of aviation, naval vessels and industrial gas turbine, also for the manufacture of the conversion equal energy source transfer equipment of aerospacecraft, rocket engine, nuclear reactor, petrochemical equipment and coal.Superalloy is that current Aeronautics and Astronautics, naval vessel, vehicle, nuclear power, industrial combustion machine irreplaceable critical material, particularly turbine blade, the turbine disk and combustion chamber are all the more so.Superalloy can bear certain stress and have the alloy of anti-oxidant or resistance to corrosion under 600-1200 ℃ of high temperature.By matrix element, mainly can be divided into iron-base superalloy, nickel base superalloy and cobalt base superalloy.By preparation technology, can be divided into wrought superalloy, cast superalloy and powder metallurgy high-temperature alloy.By schedule of reinforcement, there are solution strengthening type, precipitation strength type, oxide dispersion intensifying type and fiber strengthening type etc.
The manufacturing process technology difficulty of superalloy is large, and production cost is high, and specification of quality is high, and commercial value is high.Overwhelming majority high-temperature alloy part is by machined, and the material proportion of the shared superalloy of its turning is heavy tall and big by 20%~80%, and the turning surface greasy dirt after machining is many, and impurity is mainly with being all employing degradation level toward producer or making waste disposal.Greatly reduce as the proper value of alloy own, waste a large amount of metallic substance and resource.
Summary of the invention
The invention provides a kind of superalloy and cut the clean method of material, the ingot casting chemical composition that can obtain after superalloy remelting can be cut material in the consistent chemical composition of processed front material with superalloy, has greatly improved utility value and the resource regeneration of superalloy bits material.
The present invention is achieved by the following technical solutions: a kind of superalloy is cut the clean method of material, and concrete operation step is as follows:
(1) superalloy turning is carried out to pre-treatment go-on-go, manually turning is deposited on clean ground, with iron hook, turning is separately carried out to go-on-go processing, remove the nonmetallic impurity thing in turning.
(2) clean the making of case for superalloy turning: with thickness, be the stainless plate of 4~6mm trade mark 304, at steel plate punching Φ 6~Φ 8mm, mutual spacing 15~20mm evenly arranges, then be welded into case 1m*1m square chest, bottom is welded with, both sides suitable for reading welded suspending hook, chest size also can be made and determine according to the size of cleaning sink size;
(3) the good superalloy turning material of go-on-go is cased, every case reserved point space suitable for reading is too not full, and sign is known the turning steel grade trade mark, quantity;
(4) in groove, put into water, allocate 10% sodium hydroxide NaOH scavenging solution into, the scavenging solution preparing is heated to 40 ℃~60 ℃, then turning material having boxing is hung in and in scavenging solution, soaks 15-20 minute, then hang to clear water and soak 5 minutes, then with clear water, rinse well;
(5) turning cleaning up is dried anhydrous, hang in electric furnace and toast, storing temperature: 400 ℃-480 ℃; Insulation 2h.Object is that turning surface moisture is got rid of, to meet melting requirement ingot casting;
(6) turning is carried out to briquetting packing clamp dog shape with metal wrapping machine, while being convenient to melting, throw stove and carry out melting;
(7) superalloy turning is carried out to the chemical composition that melting ingot casting waits until that superalloy itself is consistent with medium-frequency induction furnace;
(8) through melting ingot casting, can be superalloy starting material, in the ratio of returning, allocate vacuum metling or induction furnace smelting into, the utility value of long-pending large raising superalloy turning, saves ample resources.
This method can also be processed other metal turnings, planing, sawing etc.
Beneficial effect of the present invention: the clean method of cutting material by a kind of superalloy of the present invention comprises: cut pre-treatment go-on-go, vanning, the preparation scavenging solution of material, the ingot casting chemical composition of heating, clean, can obtain after superalloy remelting after oven dry, briquetting, reflow step can be cut material in the consistent chemical composition of processed front material with superalloy, has greatly improved utility value and the resource regeneration of superalloy bits material.
Embodiment
Below the present invention is described in further detail:
A kind of superalloy of the present embodiment is cut the clean method of material, and concrete operation step is as follows:
(1) superalloy turning is carried out to pre-treatment go-on-go, manually turning is deposited on clean ground, with iron hook, turning is separately carried out to go-on-go processing, remove the nonmetallic impurity thing in turning.
(2) clean the making of case for superalloy turning: with thickness, be the stainless plate of 4~6mm trade mark 304, at steel plate punching Φ 6~Φ 8mm, mutual spacing 15~20mm evenly arranges, then be welded into case 1m*1m square chest, bottom is welded with, both sides suitable for reading welded suspending hook, chest size also can be made and determine according to the size of cleaning sink size;
(3) the good superalloy turning material of go-on-go is cased, every case reserved point space suitable for reading is too not full, and sign is known the turning steel grade trade mark, quantity.
(4) in groove, put into water, allocate 10% sodium hydroxide NaOH scavenging solution into, the scavenging solution preparing is heated to 40 ℃~60 ℃, then turning material having boxing is hung in and in scavenging solution, soaks 15-20 minute, then hang to clear water and soak 5 minutes, then with clear water, rinse well.
(5) turning cleaning up is dried anhydrous, hang in electric furnace and toast, storing temperature: 400 ℃-480 ℃; Insulation 2h.Object is that turning surface moisture is got rid of, to meet melting requirement ingot casting.
(6) turning is carried out to briquetting packing clamp dog shape with metal wrapping machine, while being convenient to melting, throw stove and carry out melting.
(7) superalloy turning is carried out to the chemical composition that melting ingot casting waits until that superalloy itself is consistent with medium-frequency induction furnace.
(8) through melting ingot casting, can be superalloy starting material, in the ratio of returning, allocate vacuum metling or induction furnace smelting into, the utility value of long-pending large raising superalloy turning, saves ample resources.
The beneficial effect of the present embodiment is: reasonable in design, the ingot casting chemical composition that can obtain after superalloy remelting can be cut material in the consistent chemical composition of processed front material with superalloy, has greatly improved utility value and the resource regeneration of superalloy bits material.
