Abstract

The object of the present invention is to provide an apparatus for producing an alloy, including: a casting device which casts a molten alloy using the strip cast method; a crushing device which crushes the cast alloy after casting; and a heating device which keeps the thin laminas of the cast alloy after crushing at a predetermined temperature or which heats the thin laminas of the cast alloy after crushing, wherein the heating device is equipped with a container and a heater.

Description

technical field [0001] The invention relates to a plant for the production of alloys. In particular, the present invention relates to an apparatus for producing rare earth element-containing alloys, including R-T-B type alloys (wherein R is at least one or more rare earth elements including Y, and T is Metal always including Fe, B is boron). [0002] This application claims the benefit of priority to Japanese Patent Application No. 2006-106793, filed April 7, 2006, and U.S. Provisional Application No. 60 / 792,647, filed April 18, 2006, both of which The entirety of this application is incorporated herein by reference. Background technique [0003] R-T-B magnets with the highest energy product among permanent magnets have been used in hard disks (HD), MRIs (magnetic resonance imaging), various types of motors, etc. due to their excellent performance. In recent years, applications of R-T-B type magnets to automobile motors have increased due to high expectations for energy s...
