摘      要：The present study investigates on the continuous casting of near-net shape aluminum billet using electromagnetic casting and stirring *** machine for continuous casting process involves round, square and rectangular billets;therefore it requires additional multistep forging process to fabricate final products.A new process for the designed free-shaped billets offers some advantages:the process of extrusion and forging is simplified and the cost of plastic working can be greatly *** order to reduce the peculiar problems such as surface crack and internal defect due to inhomogeneous heat transfer through solidified billets,electromagnetic casting and stirring technique were *** the numerical computer simulation,we have calculated the slit design of the free-shaped *** free-shaped aluminum billet was continuously cast at the various casting speed and coil current of about 1,*** velocity and melt pool depth were *** and microstructure of the free-shape aluminum billet using EMC and EMS techniques were compared with those of the billet using the conventional DC casting.
