VACUUM SYSTEM FOR VACUUM MELTING AND CASTING METAL, AND VACUUM MELTING AND CASTING METHOD USING SAME

摘要

The present invention relates to a vacuum system for vacuum melting and casting metal, and a vacuum melting and casting method using same, and more particularly, to a vacuum system for vacuum melting and casting metal, said vacuum system comprising: a vacuum pump device (256); a vacuum melting chamber (20) which is connected to the vacuum pump device (256) to enable metal melting under a vacuum condition, and which has an interior equipped with a melting furnace (110); a material injection tube (120) connected to the vacuum pump device (256) to provide metal material (01) into the vacuum melting chamber (20) under a vacuum condition; and a casting device (400) connected to the vacuum pump device (256) and the vacuum melting chamber (20) to perform casting by using the molten metal supplied from the vacuum melting chamber (20) under a vacuum condition. The present invention also relates to a vacuum melting and casting method using the vacuum system.
