FREE CASTING METHOD, FREE CASTING APPARATUS, AND CASTING

摘要

Free casting process according to the invention, resulting in the external side surface of the film lead-out area temporarily given to the source to maintain the molten metal by (F) (P), for example deriving step for deriving from the molten metal surface level of the molten metal, and a molding step for obtaining a molded article solidified by holding the molten metal (MS) are derived in accordance with the set path (L1) in accordance with the desired shape of the casting, and the maintenance is defined as the boundary between the molten metal held in the molten metal and a formed article forming step Coagulation is then molded into a desired shape by the solidified casting is an external force to the molten metal at a position between the non-binding part of the holding route in the vicinity of the surface level of the molten metal and the molten metal surface. ;
