Abstract

Procedure for decarburizing highly carburated ferromanganes0 or highly carburated ferrochrome by refining with the use of enveloping gas nozzles, the alloy melt being excessively heated before oxygen insufflation, for example at a temperature of more than 100ºC over the melting range, characterized in that the temperature of the alloy melt is increased by oxygen insufflation -without the addition of cooling agents- in the case of ferromanganese at a temperature from above 1,650ºC to 1,900ºC and in the case of ferrochrome to a temperature from above 1,750ºC to 2,000ºC, forming a manganese oxide phase or a chromium oxide phase with a high melting point, and because after this this metal oxide phase is totally reduced on the one hand by incorporation of lime and on the other hand by addition of solid reducing agents, such as silicon and aluminum and/or alloys thereof mos.
