<p>The invention relates to a method and arrangement for producing liquid iron in an electric melter or furnace (10). The method and arrangement relate to producing liquid iron in the electric melter (10) utilising highly reduced sponge iron, which is defined as sponge iron resulting from reduction of iron bearing material, and having a degree of metallisation being in excess of 60%. (Metallisation is expressed as analyzed metallic iron divided by analysed total iron). The method and arrangement relate to transferring the highly reduced sponge iron, together with at least some residual carbon, to a melter (10) in a hot state and substantially in the absence of oxygen. This avoids heat loss and reoxidation. The highly reduced sponge iron and residual carbon are then passed in a controlled manner (35) into the melter (10), where one or more electrodes (30) operate in a low resistance mode.</p> |
