method of melting manganese

  • Method for electroslag remelting of a manganese-copper

    A manganese-copper-nickel alloy is remelted to form high quality ingots or slabs which are capable of undergoing hot-working in the "as cast" form by electroslag remelting the alloy under a flux composition prepared by fusing a mixture consisting essentially of from about 50 to about 85 barium fluoride and from about 15 to about 50 calcium fluoride by weight.
