Electrical energy is generated by feeding oxygen through a solid electrolyte wall in contact with a bath of molten metal, the positive electrode being provided on the surface of this wall defining the gas space while the negative electrode is provided in the melt. Carbon monoxide released when the oxygen reacts with dissolved carbon in the melt is collected for further use and the carbon in the melt is replenished in the form of solid carbon particles which can be entrained into the melt in carbon monoxide gas.

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.

Process of refining iron in oxygen converters with additions of

The invention provides variation in the delivery of oxygen to converters for refining metal. Thus, oxygen blowing into such converters in unstationary manners, i.e., varying degrees of pressure and/or flow rate, is performed by means of partialization of the nozzles of the lance heads, or by means of decreases in the penetration capacities of the oxygen jets throughout the blowing process or during a part only of the same resulting in greatly improved reaction rates.

Method and device for blowing oxygen in metal refining converters in

The object of the present invention consists of improved nozzles for the lance heads for blowing oxygen from above, in the refining processes.

Nozzles of the lance heads for blowing oxygen from above in the refining

In a process for measuring the flow rate of a gas formed in an oxygen conversion process in which conversion process oxygen is introduced into an oxygen converter containing a material to be oxidized and gaseous effluent, including a gas formed in the oxygen converter, is withdrawn, the process is improved by including in the oxygen feed to the converter from 0.15 to 1% by volume argon, as a tracer, and determining the concentration of the argon in the gaseous effluent at the mouth of the converter or at a point before which the effluent gases are mixed with air or pollutant or before which the effluent gases are subjected to a combustion reaction.
