Abstract
The invention discloses an aluminum compressor housing of a refrigerator. The aluminum compressor housing of the refrigerator is characterized in that an ZL104 aluminum alloy material is used and casted to form the aluminum compressor housing by a low-pressure casting process; the process specifically comprises the following steps: (1) smelting the prepared ZL104 aluminum alloy and a furnace burden; (2) processing the smelted molten aluminum by the low-pressure casting process; (3) processing the surface of a casting subjected to the low-pressure casting by a thermal treatment process; (4) finally inspecting the casting. The aluminum compressor housing of the refrigerator, processed by the aforementioned processes, is high in air tightness, high in safety, and long in service life; the ZL104 aluminum alloy is used, so that the casting performance is high, and the corrosion resistance is high; various performances of the compressor housing subjected to the low-pressure casting process and the thermal treatment can meet the standard; the aluminum compressor housing is high in economic benefit.
Description
Technical field
The present invention relates to appliance field, particularly relate to a kind of aluminum alloy ice header compressor shell.
Background technology
Low pressure casting is a kind of Special Processes of Metal Castings technique, and it is that Bath adds the application of principle in Foundry Production.With regard to the operating pressure of low pressure casting, it is a kind of new pouring technology between compression casting and gravitational casting.In the airtight container (crucible) that aluminium alloy is housed, pass into dry compressed air (or inert gas), act on keep certain pouring temperature alloy liquid level on, cause the pressure differential in airtight container and in casting mold die cavity, make alloy under the effect of lower mold filling pressure (0.01 ~ 0.05MPa), along stalk endoporus from bottom to up through rising liquid passage, casting mold cast gate, be filled with reposefully in casting mold, be full of after die cavity until aluminium alloy, increase air pressure, make the crystallization and freezing under higher pressure effect of the aluminium alloy in die cavity, then the pressure in removal airtight container, allow stalk, in running channel, the aluminium alloy of ot-yet-hardened relies on the gravity of self to fall back in crucible, open casting mold again and take out foundry goods.
Low pressure casting can adopt various casting mold, generally is room temperature to the operating temperature of non-metal type, first particular/special requirement, and just has certain requirement to the operating temperature of metal mold.During as low pressure casting aluminum alloy, the operating temperature general control of metal mold at 200 ~ 250 ° of C, when pouring into a mould thin-wall complicated, can up to 300 ~ 350 ° of C.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of aluminum alloy ice header compressor shell, and the properties of compressor case can be made all up to standard, and air-tightness is good, and security is high, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of aluminum alloy ice header compressor shell, it is characterized in that, what described aluminum alloy ice header compressor shell adopted is ZL104 aluminum alloy material, by low-pressure casting process casting, concrete steps are as follows: ready ZL104 aluminium alloy and furnace charge are carried out melting by (1); (2) melted aluminium liquid is carried out low-pressure casting process; (3) cast(ing) surface after low pressure casting adopts Technology for Heating Processing; (4) final inspection of foundry goods.
Further, the pressure of described low-pressure casting process controls at 20-50KPa.
Further, the temperature of described Technology for Heating Processing controls at 200 DEG C-300 DEG C.
The invention has the beneficial effects as follows: a kind of aluminum alloy ice header compressor of the present invention shell, the aluminum alloy compressor Shell produced by a lot of operation is good, security is high, long service life, ZL104 aluminium alloy is adopted to have good castability, corrosion resistant type is good, makes the properties of compressor case all up to standard, have very high economic benefit by low-pressure casting process and heat treatment.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
A kind of aluminum alloy ice header compressor shell, it is characterized in that, what described aluminum alloy ice header compressor shell adopted is ZL104 aluminum alloy material, described ZL104 aluminum alloy material can be heat-treated, air-tightness is high, corrosion resistance is high, by low-pressure casting process casting, concrete steps are as follows: ready ZL104 aluminium alloy and furnace charge are put into and melted down pot and carry out melting by (1); (2) melted aluminium liquid is carried out low-pressure casting process, the pressure of described low-pressure casting process needs to control at 20-20KPa; (3) cast(ing) surface after low pressure casting adopts Technology for Heating Processing, and the temperature of described Technology for Heating Processing controls at 200 DEG C-300 DEG C; (4) final inspection of foundry goods, casting of appearance of cast requirement, mechanical property etc. all meet acceptance criteria can.
The aluminum alloy compressor Shell that the present invention one is produced by a lot of operation is good, security is high, long service life, ZL104 aluminium alloy is adopted to have good castability, corrosion resistant type is good, make the properties of compressor case all up to standard by low-pressure casting process and heat treatment, there is very high economic benefit.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
