The invention discloses a preparation process and the special equipment thereof for novel grain intensifying aluminum radical
composite material. The melting and mixing process of the preparation method are performed in a body-connected sealing equipment, the aluminum matrix
alloy is added through a charging opening of a melting
pool, after the aluminum matrix
alloy is melted, a valve at the bottom part of the melting
pool is opened, the melted
liquid state aluminum matrix
alloy directly flows into the mixing
pool, when the liquid level of the mixing pool reaches the defined height, the valve is closed, the pretreated SiC is added through a charging opening at the top part of the mixing pool, a charging rod adopting an aluminum casing as covering material is adopted when material is charged, as the aluminum casing of the charging rod is melted, the SiC is melted in the aluminum matrix alloy, then the material is sent into the die
assembly through a discharging pump, and directly made into billet material or a product. In the invention, the melting and the mixing are effectively combined, the
system of melting pool and mixing pool is simplified, the structure is simple, the controlling is simple, the cost is reasonably reduced, the content of the
silicon carbide grain in the aluminum radical
composite material of the product is stable and uniformly distributed, and the whole performance of the aluminum radical
composite material is enhanced.
