FREE CASTING METHOD FREE CASTING APPARATUS AND CASTING

摘要

free casting process according to the invention, the surface produced on the outer surface layer provided on the supply source to maintain temporarily the molten metal by the (F) out region (P), for example from the surface level of the molten metal the by solidifying keep the molten metal (MS) are derived in accordance with the set path (L1) in accordance with the derivation step, and the desired casting shape for deriving a molten metal including the molding step for obtaining a formed body, and the holding molten metal is maintained in the shaping step by at a position between the root portion of the non-binding keep the molten metal in the vicinity of the surface level of the molten metal solidification interface and defined as the boundary between the molten metal and the molded article is an external force to the molten metal is solidified after the shaping to the desired casting shape. ;
