USE OF OWN WASTE METAL IN THE PRODUCTION OF SINGLE-CRYSTAL PERMANENT MAGNETS

Abstract
The applicability of waste metal formed in the manufacture of single-crystal permanent magnets of UNDKT5AA alloy is studied. Since this waste accumulates detrimental impurities, it cannot be re-used in the production. Additional cleaning of initial melting stock with solid oxidants was applied to prevent alloy contamination with impurities. An example was provided for calculating a required solid oxidant volume. The material of graphite intermediate ladle in contact with melt was replaced with pure alumina. Waste metal formed afterwards featured a reduced content of detrimental impurities. Such waste materials were used as a melting stock component in the production of single-crystal permanent magnets. All magnets met quality requirements, while the cost of production dropped by more than 30 %.
