Abstract

A new mold for melting cast magnets with columnar crystal structure of type YuNDK(T) is developed. The use of a novel refractory material based on ceramic fibers instead of the multicomponent heat-accumulating mix for making the mold has lowered the temperature-and-time parameters of its application and made it possible to fabricate large-size YuNDKBA and YuNDKT5BA magnets with high magnetic properties by the out-of-furnace method.
