PROCEDIMENTO PER TRATTARE UNA FRAZIONE LEGGERA SCHREDDER IN UNA MASSA FUSA |
摘要 |
<p>A process and apparatus for processing a shredder light fraction including multi-duct nozzle having at least an end section positionable within a metallurgical vessel containing a molten metal bath. The shredder light fraction may be fed into the molten metal bath while using only small quantities of carrier gas, e.g., air or nitrogen, and protective gas, e.g., hydrocarbon or inert gas. The shredder light fraction and the carrier gas may be injected into the molten metal bath as a main jet and oxygen may also be injected into the molten metal bath as a secondary jet. The primary jet and the secondary jet may be surrounded by a gas jet formed by the protective gas being injected into the molten metal bath.</p> |
