Method of desulfurizing molten metal in a plasma fired cupola |
| abstract |
A method of desulfurizing iron in a plasma fired cupola having a plurality of feed nozzles each of which have a particulate feed and a plasma torch connected thereto; a fluxing agent such as CaO, MgO, CaCO3, MgCO3 or CaCO3MgCO3 is fed to the feed nozzle and melted by the plasma torch; the molten fluxing agent mixes directly with the molten iron in the cupola 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. |
