Abstract
The utility model relates to electromagnetic stirring casting apparatus for metal-base composite materials. The utility model is composed of a crucible, a furnace tube, a heating body, a heat insulating layer and a magnetic field generator. The utility model is characterized in that the furnace tube is covered by the heating body, the heat insulating layer is used by the outer face to insulate heat, the magnetic field generator is positioned on the outer part of the furnace tube, and the crucible is arranged in the furnace tube. The crucible is made of nonmagnetic materials such as graphite and stainless steel. The utility model can improve the comprehensive performance of casting type metal-base composite materials.
Description
The utility model relates to the foundry engieering of metal-base composites, and a kind of device of making composite with the electromagnetism stirring method is provided especially.
In decades, powder metallurgical sintering process is existing extensive work in metal-base composites research, because technical difficulty, complex process, the more high reason of cost is limited to, and has occurred the melt casting process of a series of Composite Preparation such as permanent mold casting, accurate shell moulded casting, semi-solid rheological casting, compression casting, negative pressure casting or the like in succession.Wherein using more is melt swirl method and composite casting, common feature in the various castings is to produce the liquid whirlpool with mechanical agitation, the compound particle that joins in the melt rotates by melt, enter in the base material, in fact so-called composite casting is swirl method and the combining of pressure casting method, also be unable to do without mechanical agitation, as seen stirring melt is the key link in the casting Composite Preparation.In the mechanical agitation process, the inhomogeneous compound particle distribution that causes of normal appearance " dead angle " or mechanical force and the inhomogeneities of base material tissue, thereby cause composite material combination property not high.Electromagnetic agitating technology is widely used in continuous casting steel machine, US Basic Application Number research is more, Japanese industry is used more general, electromagnetic agitation is to improving ingot quality, refinement and the effect of homogenising microscopic structure are fairly obvious, economic effect is very big, prepares composite but electromagnetic agitating technology is used for casting, still beyond example.
The purpose of this utility model provides a kind of preparation facilities of metal-base composites, to improve the combination property of cast moulding metal-base composites.
The utility model as shown in Figure 1, a kind of metal-base composites electromagnetic agitation casting device, constitute by crucible 1, boiler tube 3, calandria 4, thermal insulation layer 5, magnetic field generator 6, it is characterized in that, calandria 4 envelopes boiler tube 3, and the outside is placed in the pipe outside with thermal insulation layer 5 thermal insulation, magnetic field generator 6, place crucible 1 in the boiler tube 3, crucible 1 usefulness nonmagnetic substance such as graphite, stainless steel are made.Magnetic field generator can be that rotating excitation field also can be linear travelling-magnetic-field.The purpose of calandria 4 is to make melt keep uniform temperature when electromagnetic agitation.In when casting, after melt 2 is poured casting mold into, do not coexist melt when being in the two-phase section temperature immediately or according to alloy, add rotation magnetic field for melt 2 or linear travelling-magnetic-field carries out electromagnetic agitation.The utility model adopts electromagnetic force to replace mechanical force to stir melt; produce whirlpool; by regulating electromagnetic field intensity; change mixing power and melt rotary speed; by the melt rotation awl negative pressure that forms; compound constituent element is introduced the metal or alloy melt; realize compound; simultaneously; compound constituent element is evenly distributed, improve and base material melt wellability, not be subjected to compound constituent element shape (particle or whisker or fiber) state (coated particle or preliminary treatment particle) restriction; because electromagnetic field evenly distributes in whole melt; can avoid " dead angle " or the appearance of weakness zone that exist in the mechanical agitation, electromagnetic field can apply after casting any time, also has the effect of semi-solid casting; thereby the utility model technology has the whirlpool casting simultaneously concurrently; the advantage of rheocasting; obtain base material dense structure, crystallization of refinement, base material tissue and compound constituent element are evenly distributed; superiority such as compound interface is tight are a kind of innovative technology approach that shows unique characteristics.
