Description
Technical field
The invention belongs to field of composite material preparation, more particularly to a kind of paddling process to prepare particulate reinforced metal-based composite wood
Material crucible, preparation and its vacuum adjustable pressure casting technology especially suitable for particle enhanced aluminum-based composite material.
Background technology
The metal-base composites (Metal Matrix Composites, abbreviation MMC) that the latter stage seventies occurs, because of it
With comprehensive mechanical properties such as good specific strength, specific stiffness, elevated temperature strength, wearability, corrosion resistances, more flexible designs
Property, it is developed rapidly and applies.Particles reiforced metal-base composition, especially SiCp/Al composite materials have good
Economy, become the metal-base composites of most study.The preparation method of the SiCp/Al composite materials of comparative maturity has：
Powder metallurgic method, stirring casting method, spray deposition, and paddling process prepares SiCp/Al composite materials since technique is simple, equipment
Less investment, be easily achieved the advantages that industrialization, and more other method applications are more extensive.
A kind of pressure-adjusting casting method and pressure regulation crucible, the tune are disclosed in patent of invention ZL 2,004 10009617.6
Die casting is made includes crucible body and water-cooling flange with crucible, and water-cooling flange is welded on the upper end of crucible body, in the upper table of water-cooling flange
Face sets heat-insulated asbestos groove and seal groove, and the cooling that a cavity is used for recirculated water, the outer of water-cooling flange are set inside water-cooling flange
If the water inlet interface and water outlet mouthpiece of recirculated water, crucible air-path interface are located at the top of crucible body.Can be in work by the crucible
(- 0.1MPa) melts aluminium alloy under industry vacuum condition, adds SiC particulate after unloading vacuum, utilizes patent of invention ZL 2,005 1
That is announced in 0011160.7 prepares the vacuum double-stirring device of enhancing aluminum-base composite material by silicon carbide particles, using patent of invention
The double stirring castings of a kind of vacuum machine for preparing particle enhanced aluminum-based composite material announced in ZL 2,005 1 0011526.0
Method, can prepare SiCp/Al composite materials with mechanical agitation.But above-mentioned crucible has the following disadvantages in use.
First, in SiCp/Al composite materials are prepared using the crucible, the SiC particulate powder of addition can be partly viscous
Tie in crucible internal walls and the blender surface beyond molten metal, vacuumize in whipping process, SiC particulate powder can not
Removed from bonding surface, during vacuum and transfer blender is subsequently unloaded, part adhesive is in crucible internal walls and blender table
The SiC particulate powder in face can be fallen into prepared composite material, influence the preparation quality of composite material, while part adhesive exists
The SiC particulate powder of crucible internal walls also can produce harmful effect to composite material base or sample preparation.
Secondly, SiCp/Al composite materials prepare and need to vacuumize the chamber of crucible in forming process, once crucible chamber
Room is poorly sealed, and high-temperature gas constantly can flow into external pipeline by the air-path interface of crucible, cause external pipeline temperature liter
Height, influences its safety of being on active service and even leads to major accident.
3rd, the air-path interface of crucible is located on crucible body, that is, the volume utilization for limiting crucible also increases pumping very
The excessive risk of aluminium alloy in null process.
4th, the crucible body and water-cooling flange of crucible weld together, and make crucible manufacture complicated, crucible body is loss in addition
Part, causes replacement or the inconvenient maintenance of crucible, cost increase.
The content of the invention
Patent technology to be solved of the present invention is to be directed to granular powder in particles reiforced metal-base composition preparation process
Body is bonded in crucible internal walls and blender surface is difficult to remove, and causes when vacuumizing from the high-temperature gas of crucible air-path interface outflow
The problems such as external pipeline temperature raises, and aluminium alloy is excessive in vacuum, and crucible replacement and maintenance cost is high, there is provided one
Kind paddling process prepares particles reiforced metal-base composition crucible.
Technical solution is used by patent of the present invention solves its technical problem：The present invention relates to a kind of preparation of paddling process
Grain enhancing metal-base composites crucible, including：Telophragma (1), outer packing (2), crucible body (3), interior packing (4), telophragma
(1) fluting and tapped blind hole on, with packing I (5) and packing II (6) and agitating device sealing, built-in cooling water channel and give crucible body
(3) gas circuit for being evacuated and supplying gas, outer rim arrangement locating piece, realization and crucible body (3) horizontal location, crucible body (3) manufacture easy to produce,
Fluting and tapped blind hole on its disk, with outer packing (2), interior packing (4) seals with telophragma (1), by external weights and fastens
Clamp force realizes the crucible axial compression, and uniformly distributed venthole can be to adhering on crucible body (3) inner wall and blender on the inside of telophragma (1)
Particle is cleared up, and cooling water channel built in telophragma (1) can prevent temperature from can also be detached to agitating device conduction in hot-air
When implement effective temperature-reducing.
The present invention has the following advantages that compared with prior art：
Crucible involved in the present invention has independent telophragma (1) and crucible body (3).Crucible body (3) is wearing detail, such a design
It can be simple to manufacture crucible body (3), repair and replacement are convenient, and cost is low.
Cooling water channel built in the telophragma (1) of crucible involved in the present invention and the gas circuit for being evacuated and supplying gas to crucible body (3), and
On the inside of it uniformly distributed venthole, blown by gas circuit built in telophragma (1) can be to adhering on crucible body (3) inner wall and blender
Particle is cleared up, and cooling water channel built in telophragma (1) can prevent temperature from can also be detached to agitating device conduction in hot-air
When implement effective temperature-reducing.
Crucible involved in the present invention is by external weights and fastens power and realizes its axial compression.
The pumping of crucible involved in the present invention and the gas circuit supplied gas are located on telophragma (1), and used gas circuit knot
Structure is conducive to prevent that aluminium alloy is excessive, while improves the utilization rate of crucible body (3).
