Abstract
The utility model invents a preparation device for realizing ceramic reinforced metal base composite material and does not need a series of vacuum devices. The utility model is composed of a mechanical agitation part and a furnace part; under the protection of the noble gas, the alloy melting liquid is stirred at high speed through a mechanical stirrer. Simultaneously, the reinforcement material is added in the alloy melting liquid; after sufficient stir, the alloy melting liquid forms the metal base composite material in which the reinforcement material is distributed uniformly. The mechanical and physical property of the metal base composite material is higher than the alloy which is not reinforced. The utility model allows high shearing rate; the small whirl is used for stirring, which eliminates the defects that in common stirring method, the impurity is mixed, the gas is involved, and the reinforcement material are gathered, etc.
Description
The utility model relates to field of metallurgy, belongs to the equipment of metal-base composites preparation, specifically is the liquid preparation facilities that stirs the ceramic reinforced metal based composites.
Metal-base composites is owing to have advantages such as high specific strength, high ratio modulus, high heat-resisting, low thermal coefficient of expansion, be nearly two development one of hi tech and new materials the most rapidly during the last ten years, western developed country, USSR (Union of Soviet Socialist Republics) and China all attach great importance to the research in this field, but adopt be mostly pressure infiltration casting, spray deposition, powder metallurgic method, semi-solid state composite algorithm etc.All there is the complicated problem such as huge of cost height, equipment in various degree in these methods, adopt the liquid pottery that stirs to strengthen and prepare metal-base composites, have the tempting prospect that cost is low, be suitable for mass industrialized production, but its preparation equipment is crucial.The liquid whipping appts of state such as the U.S., Japan is all worked under vacuum condition, and equipment complexity, production efficiency are low, and the price of preparation material is more expensive, (sees J.Mater.Sci.1993,28 (9): 2459; J.Jap.Inst.of Metals, 1990,54 (8): 933), at present, the liquid agitator structure that is used for scientific research and production belongs to propeller shape substantially, the crucible aspect ratio is 1: 1, and agitator blades is about 0.7 with crucible diameter than generally, thereby is easy to generate defectives such as being mingled with, rolling up gas and reinforce reunion in the matrix material of preparation.
We entrust the Scientific and Technical Information Institute, Shaanxi Province to carry out looking into newly with regard to the invention theme recently, retrieved the DIALOG system of the U.S., domestic and international patent documentation and non-patent literature etc., its conclusion is taken passages as follows: this problem is being better than pertinent literature aspect preparation small-particle enhancing metal-base composites and the industrial applications.
The purpose of this utility model is will invent a kind of liquid state that can prepare to stir the ceramic reinforced metal based composites, and do not need the cost height, baroque vacuum apparatus just can be prepared the ceramic reinforced metal based composites that ceramic reinforce is evenly distributed, combines with matrix alloy closely, the mechanics physicals is good; Can allow high shear rates, little vortex to stir, stir full and uniform; Mixing Machine and smelting furnace are separate, not only are convenient to operate the liquid state of also being convenient to keep in repair and stir ceramic reinforced metal based composites preparation facilities.
Below in conjunction with accompanying drawing the utility model is elaborated, embodiment is also merged wherein.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model crucible.
Fig. 3 is the structural representation of the utility model agitator.
Realization of the present utility model is that whole device comprises liquid the stirring and smelting furnace, its liquid mixing part comprises Mixing Machine and hoisting appliance, as shown in Figure 1, intrinsic column 2 on bearing 1, top chock and crossbeam 5 are housed on the column 2, elevator 3 is housed on the top chock, agitator motor 6 is housed on the crossbeam 5, agitator 7 is installed in the termination, the axle of agitator 7 is over against crucible 10 centers that are arranged in smelting furnace 11, feed rod 14, leading screw 4 is parallel with column 2, and crossbeam 5 moves up and down by leading screw, smelting furnace 11 is positioned at column one side, built-in crucible 10, the melting fire door is provided with sealing cover 9, and sealing cover 9 is provided with rare gas element ventpipe 13 and ceramic charging opening 8.Blade 16 diameters and crucible diameter on the agitator 7 are 0.3～0.6.This device can be suitable for the preparation that pottery strengthens multiple alloy substrate matrix materials such as aluminium, copper, zinc, magnesium, tin, lead.
Realization of the present utility model is that also the aspect ratio of crucible 10 in the device is 2.0～3.5, sees Fig. 2, and the crucible inwall can be provided with spoiler 15, also can not be provided with.
Realization of the present utility model also is intrinsic some agitating vanes 16 on the vertical stir shaft of agitator 7, such as four combinations.As shown in Figure 3, blade becomes 10 °～45 ° angles with stir shaft, and 15 °～45 ° is preferred angle, and horizontal sextant angle is 0 °～90 ° between sheet, belongs to space on-plane surface spiral.
During the utility model work; rare gas element is by ventpipe 13; enter smelting furnace; under the protection of inert gas; agitator 7 high-speed stirring alloy liquid 12 add ceramic reinforce in alloy liquid 12 by charging opening 8 simultaneously, and the position of agitator can be regulated by two motors; fully stir postforming, the metal-base composites that availability is good.
Owing to reasonably designed liquid Mixing Machine and smelting furnace and the cooperation between them, determined the aspect ratio of crucible, agitator structure and with the hoisting appliance that is equipped with of crucible, governor mechanism etc., make the utlity model has and do not need complex structure and the high vacuum apparatus configuration of expense, can allow high shear rates, little vortex stirs, stir fully, reinforce is evenly distributed, thereby combine closely with matrix alloy and can prepare mechanics, the ceramic reinforced metal based composites that physicals is good such as aluminium base, the magnesium base, zinc-base, copper base etc., existing being mingled with when this device also can be eliminated common whipping appts and prepares matrix material simultaneously, volume gas, defectives such as reinforce reunion, and whole apparatus structure is simple, cost is low, is convenient to Operation and maintenance.
