Description
Technical field
The invention belongs to field of composite material preparation, more particularly, to a kind of paddling process prepares particulate reinforced metal-based composite wood
Material crucible, is particularly well-suited to preparation and its vacuum adjustable pressure casting technology of 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
There is good specific strength, specific stiffness, elevated temperature strength, wearability, the comprehensive mechanical property such as corrosion resistance, more flexible designs
Property, it is developed rapidly and apply.Particles reiforced metal-base composition, especially SiCp/Al composite has well
Economy, become the metal-base composites of most study.The preparation method of the SiCp/Al composite of comparative maturity has：
Powder metallurgic method, stirring casting method, spray deposition, and paddling process preparation SiCp/Al composite is due to process is simple, equipment
Less investment, the advantages of be easily achieved industrialization, more other methods applications are more extensive.
A kind of pressure-adjusting casting method and pressure regulation crucible, this tune is disclosed in patent of invention ZL 2,004 10009617.6
Die casting is made and is included 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 arranges heat-insulated asbestos groove and seal groove, sets a cavity for the cooling of recirculated water, the outer of water-cooling flange inside water-cooling flange
If the water inlet interface of recirculated water and water outlet mouthpiece, crucible air-path interface is located at the top of crucible body.Can be in work by this crucible
(- 0.1MPa) fusing aluminium alloy under industry vacuum condition, adds SiC particulate, using patent of invention ZL 2,005 1 after unloading vacuum
The vacuum double-stirring device preparing enhancing aluminum-base composite material by silicon carbide particles announced in 0011160.7, using patent of invention
A kind of double stirring casting of vacuum machine preparing particle enhanced aluminum-based composite material announced in ZL 2,005 1 0011526.0
Method, can prepare SiCp/Al composite with mechanical agitation.But above-mentioned crucible has the following disadvantages in use.
First, using in this crucible preparation SiCp/Al composite material, the SiC particulate powder body of addition can partly glue
Knot in crucible internal walls and is exposed to agitator surface beyond molten metal, and in evacuation whipping process, SiC particulate powder body can not
Remove from bonding surface, during subsequently unloading vacuum and transfer agitator, part adhesive is in crucible internal walls and agitator table
The SiC particulate powder body in face can fall in prepared composite, the preparation quality of impact composite, and part adhesive exists simultaneously
The SiC particulate powder body of crucible internal walls also can produce harmful effect to composite base or sample preparation.
Secondly, need the chamber evacuation to crucible in the preparation of SiCp/Al composite and forming process, once crucible chamber
Room is poorly sealed, and High Temperature Gas are known from experience constantly by the air-path interface inflow external pipeline of crucible, lead to external pipeline temperature liter
Height, affects 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, limit crucible volume utilization also increase take out true
The excessive risk of aluminium alloy in null process.
4th, the crucible body of crucible and water-cooling flange weld together, and so that crucible is manufactured complicated, and crucible body is loss in addition
Part, causes replacing or the inconvenient maintenance of crucible, and cost increases.
Content of the invention
Patent of the present invention technology to be solved is for granular powder in particles reiforced metal-base composition preparation process
Body is bonded in crucible internal walls and agitator surface is difficult to remove, and the high-temperature gas flowing out from crucible air-path interface during evacuation leads to
External pipeline temperature raises, and the problems such as aluminium alloy is excessive in vacuum, and crucible replacement and maintenance cost is high, provides one
Plant paddling process and prepare particles reiforced metal-base composition crucible.
Patent of the present invention solves its technical problem and be employed technical scheme comprise that：A kind of paddling process prepares grain reinforced metal
Based composites crucible, including：Telophragma (1), outer packing (2), crucible body (3), interior packing (4).The upper fluting of telophragma (1) and
Tapped blind hole, is sealed with packing and agitating device, built-in cooling water channel and pumping and the gas circuit supplied gas, and outer rim arranges locating piece,
Realize and crucible body (3) horizontal location；Crucible body (3) is easy to standardization and the manufacturing, and fluting and tapped blind hole on its disk, with outer
Packing (2), interior packing (4) is sealed with telophragma (1).Telophragma (1), outer packing (2), crucible body (3), interior packing (4) pass through outer
Portion's weight and the power that fastens realize axial compression.Being blown by the built-in gas circuit of telophragma (1) can be to crucible body (3) inwall and agitator
The granule of upper adhesion is cleared up, and the built-in cooling water channel of telophragma (1) can prevent temperature from conducting to agitating device also can be in heat
Implement effective temperature-reducing when air detaches.
The present invention compared with prior art has the advantage that：
Crucible involved in the present invention has independent telophragma (1) and crucible body (3).Crucible body (3) is wearing detail, this kind of design
Crucible body (3) can be made to be simple to manufacture, repair and replacement are convenient, low cost.
The built-in cooling water channel of telophragma (1) of crucible involved in the present invention and the gas circuit being evacuated to crucible body (3) and supplying gas, lead to
Cross the built-in gas circuit of telophragma (1) and blow and the granule of adhesion on crucible body (3) inwall and agitator can be cleared up, telophragma
(1) built-in cooling water channel can prevent temperature from also can implement effective temperature-reducing when hot-air detaches to agitating device conduction.
The telophragma (1) of crucible involved in the present invention, outer packing (2), crucible body (3), interior packing (4) pass through external weights and
The power of fastening realizes axial compression.
The pumping of crucible involved in the present invention and the gas circuit supplied gas are located on telophragma (1), and the gas circuit knot being adopted
Structure desirably prevents that aluminium alloy is excessive, improves the utilization rate of crucible body (3) simultaneously.
