APPARATUS AND A METHOD FOR A SOFT MAGNETIC BMG PLATE USING A VACUUM CENTRIFUGAL CASTING, CAPABLE OF MANUFACTURING A FLAWLESS SOFT MAGNETIC BMG PLATE WITHOUT CASTING DEFECTS OR PORES

摘要

PURPOSE: A manufacturing apparatus and a method for a soft magnetic BMG plate using a vacuum centrifugal casting are provided to manufacture a plate in various thicknesses without replacing an expensive mold by installing a thickness control ring in the middle of a top mold and a bottom mold.;CONSTITUTION: A manufacturing apparatus and a method for a soft magnetic BMG plate using a vacuum centrifugal casting comprise the following steps: A top mold(302), a bottom mold(301), and a mold(300) including a thickness control ring which is selectively installed in the middle of the top mold and the bottom mold are heated at 170 deg. C to 230 deg. C under a vacuum atmosphere; A dissolved material is injected into the mold with rotating the mold in order to apply a centrifugal force of 30G to 50G; A plate is centrifugal casted inside the mold.;COPYRIGHT KIPO 2013
