Brief description of the refining of the iron by blowing oxygen

摘要

P process of refining the liquid cast iron, the converter, according to which, with the aid of at least one nozzle, is injected, at the bottom of the converter, a refining gas very oxidizing agent, which may be substantially pure oxygen, by the central duct of the nozzle, and is injected substantially pure oxygen, in the liquid state, by the peripheral circuit of the nozzle. / p & & p & this process may advantageously be implemented on any converter provided with means of ripening by the bottom and makes it possible not to introduce, during the production of the steel of impurities obstructive such as sulfur, nitrogen and hydrogen. / p
