Study on Rheo-Continuous Casting of Al-Si A356 (EN AC4200) Alloys

Abstract:

Rheo-continuous casting method is a combination of rheo- and continuous castings. In rheo-casting process the nucleation occurs on cooling slope with high rate in whole casting volume, so nuclei are numerous, resulting in very fine microstructure of nodular crystals. In this work the rheo-continuous process was carried out with a casting machine using 2 rollers of same size: diameter of 300 mm and width of 100 mm. The pouring temperature is near-liquidus. The microstructure obtained is fine (grain size < 40 μm), with nodular morphology. The mechanical properties of as-cast samples were high (the tensile strength is above 220 MPa).
