Decarburising ferrochrome or ferromanganese - by oxygen blowing with the melt superheated

High carbon ferromanganese or ferrochrome is decarburised by refining using gas envelope nozzles, e.g. with double walls, the molten alloy being super heated before blowing in oxygen to a temp. >100 degrees C above that of the fusion zone. The temp. is further heated by the blowing to 1650-1900 d...
