Abstract

The invention provides a vacuum electromagnetic stirring suction-casting system used for a composite material. The system comprises a control cabinet, an electromagnetic stirring device, a crucible, acrucible lifting device, an induction smelting device, a dust filter pipe, a vacuum tank, a suction-casting pipe, a mould, a furnace and a controller. According to the scheme, a vacuum electromagnetic stirring suction-casting method is adopted for achieving smelting and casting of an alloy and the composite material thereof, and smelting and casting under vacuum can prevent air suction in the casting process; and the technical problems of poor fluidity of the alloy and the composite material thereof, alloy component segregation, easy enhanceosome settling, non-uniform enhanceosome distribution are solved, and castings, of the alloy and the composite material thereof, with uniform distribution of components and enhanceosomes and high performance can be obtained easily.

Description

technical field [0001] The invention relates to the field of preparation of alloys and composite materials thereof, and relates to a vacuum electromagnetic stirring suction casting device and a preparation method. Background technique [0002] Composite materials have the advantages of high specific strength and specific stiffness, good wear resistance, and low thermal expansion coefficient, and are widely used in transportation, aerospace, and electrical and electronic fields. [0003] At present, the main preparation methods include powder metallurgy, liquid casting, spray deposition and so on. [0004] The powder metallurgy method has the advantages of uniform distribution of reinforcements, good interface bonding, and the ability to change the content of reinforcements in a wide range. However, its production process is complex, requires high equipment requirements, and high production costs, making it difficult to prepare large and complex components. [0005] The liqu...
