Abstract

The influence of the ceramic crucible on chemical composition stability and purity of the REM–Fe–Co–B alloy during melting in a vacuum induction furnace is studied. It is shown that using MgO and Y2O3 as a working layer of the crucible allows to increase REM content stability in REM–Fe–Co–B system alloys and ensure high purity from aluminum and oxygen impurities. Usage of cobalt «K0» grade instead of «K1Au» grade as charge material leads to a significant reduction of nickel content in the melted alloy. For the first time the technology of melting of REM–Fe–Co–B alloys for temperature-stable magnets is designed. providing stability of chemical composition (REM ±1% by mass. from goal value, Co and B ±0,5% mass. from goal value) and high purity (aluminum and nickel impurities ≤0,1% mass. of each, oxygen impurity ≤0,05% by mass).
