METHOD FOR SMELTING FINE GRAINED DIRECT REDUCED IRON IN AN ELECTRIC ARC FURNACE |
摘要 |
<p>The direct reduced iron (DRI) which for at least 80 wt-% has a grain size of not more than 3 mm is melted in an electric arc furnace. The furnace contains a bath of liquid iron. During the operation of the furnace a foamy slag layer is formed on the bath and the DRI falls by gravity through at least one movable lance into the foamy slag layer on the iron bath. Preferably, the distance of the aperture of the lance to the iron bath is kept practically constant.</p> |
