Description
Technical field
The utility model is related to a kind of aluminium alloy sealing ring casting, is related specifically to a kind of high intensity A357 aluminium alloys sealing
Ring casting.
Background technology
A357 alloys have excellent casting character, specific strength and toughness higher, good anti-fatigue performance and corrosion resistant
Corrosion energy, is widely used in the industry such as Aeronautics and Astronautics and military affairs.The mechanical property of the A357 alloy-steel castings of majority enterprise of China production
More external there can be very big difference, it is impossible to meet the demand of some Aeronautics and Astronautics products.
Utility model content
The purpose of this utility model be exactly in order to meet domestic high-quality aluminum alloy sealing ring the need for and a kind of weight is provided
Amount is light, and intensity is high, the high-quality A357 aluminium alloy sealing ring casting of good seal performance.
The utility model purpose can be achieved through the following technical solutions：
The utility model discloses a kind of aluminium alloy sealing ring casting, including using the melting of A357 aluminum alloy materials, sand mold
Gravitational casting and the aluminium alloy of heat treatment sealing ring body, the aluminium alloy sealing ring body includes generally columned
Casting body, the external diameter of the casting body is 361mm, and length is 38mm, is offered on the casting body and along its axis direction
Centre bore, the centre bore is coaxial with casting body, and the centre bore internal diameter is 239mm.
Compared with prior art, the utility model is using the aluminium alloy sealing ring using the casting of A357 aluminum alloy materials
Body, with lightweight, intensity is high, the characteristics of good seal performance, the micro- scandium of addition, Al-Ti-B intermediate alloy fining agent with
And strontium alterant, optimize Technology for Heating Processing, further increase the mechanical property of casting.
Brief description of the drawings
Fig. 1 is a kind of structural representation of aluminium alloy sealing ring casting of the utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, a kind of aluminium alloy sealing ring casting provided in figure, including use the melting of A357 aluminum alloy materials, sand
Type gravitational casting and the aluminium alloy of heat treatment sealing ring body 100.
Sealing ring body 100 includes generally columned casting body 110, on casting body 110 and along its axis direction
Centre bore 111 is offered, centre bore 111 is coaxial with casting body 110.
The external diameter of casting body 110 is 361mm, and length is 38mm, and the internal diameter of centre bore 111 is 239mm.
Specific casting method of the present utility model is as follows：
0.2% scandium is added in A357 alloys, can strongly refine a (aluminium)；Also the form of eutectic silicon can to a certain degree be improved,
But the modification effect to eutectic silicon is much smaller than strontium.Scandium, strontium joint are added, to the as-cast structure fine degenerate effect of A357 alloys
Significantly, greatly improve the mechanical property of alloy.The addition of A357 alloy al-ti-b refiners significantly affects its thinning effect,
Individually the boron of the titanium of aluminium-5-1 or the boron of the titanium of aluminium-3-3 of addition 1% have lightweight to A357 alloy structures, and intensity is high, good seal performance
Thinning effect.
The optimal solid solution of A357 alloys-single-stage aging technique is 548 DEG C of solid solutions 12h, 175 DEG C of timeliness 6h；Optimal twin-stage
The technique of timeliness be 120 DEG C of preageing 4h, after in 175 DEG C of timeliness 5h.Two-stage time effect compared with single-stage aging technique, alloy tension
Intensity improves 3.33%, and elongation percentage reaches 6%.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, the utility model can also on the premise of the utility model spirit and scope are not departed from
There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.The utility model will
Protection domain is asked to be defined by appending claims and coordinate.
