Abstract
The above invention concerns the use of sodium carbonate and various mixtures thereof in furnaces for converting iron while blowing with oxygen. This compound, suitably prepared and added to the converter with sufficient operator skill, permits one to take care of well known limitations of rapid conversion processes, notably increasing reactions removing elements which are not wanted in steel, in particular phosphorus and sulphur. After careful examination of all the aspects of the use of said materials in converters, those conditions have been identified which permit one to use with success this new method with sodium slags in all types of processing involving oxygen blowing.
