抄録

Semisolid casting of aluminum alloy is an advanced casting technology for the foundry industry. The advantages of semisolid casting are ease of casting at low temperature and high fluidity of the semisolid slurry, which have to contain granular, fine and homogeneous crystals. Conventional semisolid slurry processing is performed by electromagnetic stirring or mechanical stirring, both of which involve large equipment and high costs. In this investigation, we developed a simple semisolid process of AC4CH aluminum casting using an inclined cooling plate. Numerous α aluminum granular crystals nucleated on the inclined cooling plate during its flow, and the semisolid slurry ran into an isolated tundish. The crystals then became granular grains in the tundish. The semisolid slurry was cast into a horizontal continuous casting machine. The billet was 60 mm in diameter and 1000 mm in length and the casting speed was between 2 and 4 mm/s. The finest grain size of 50 μm could be obtained by casting at 897 K with a casting speed of 4 mm/s, an angle of 60°, and a length of 160 mm.
