Verfahren zum Entschwefeln von geschmolzenem Metall in einem plasmabeheizten Kupolofen.
摘要
<p>A method of desulfurizing iron in a plasma fired cupola (1) having a plurality of feed nozzles (21) each of which have a particulate feed and a plasma torch (25) connected thereto; a fluxing agent such as CaO, MgO, CaCO3, MgCo3 or CaCO3 MgCO3 is fed to the feed nozzle and melted by the plasma torch (23); the molten fluxing agent mixes directly with the molten iron in the cupola (1) and reacts with the sulfur in the iron; the reacted and unreacted fluxing agent combine with the slag reducing the viscosity making the slag flow better and producing a low sulfur iron in the cupola (1).</p>
