<p>The present invention relates to the improvement of metals' melting and refining processes by natural gas injection through the bottom of metallurgical reactors. It is upon the lab and semi-industrial plant experience of the inventors of the present invention, that it was found that during the injection of natural gas into liquid metals, there is substantially no cracking of methane under usual conditions of pressure and temperature in the refining processes. In such conditions, natural gas can be used as inert gas in metallurgical processes with technical and economical advantages over inert gases, introducing it through the bottom or at the surface of the liquid bath.</p> |
