  • Patent number: 4764210
    Abstract: The invention relates to a method for producing liquid in an electric melter or furnace. The method relates to producing liquid iron in an electric melter, utilizing highly reduced sponge iron, which is defined as sponge iron resulting from reduction of iron bearing material, and having a degree of metallization being in excess of 60%. (Metallization is expressed as analyzed metallic iron divided by analyzed total iron).The method comprises transferring the highly reduced sponge iron, together with at least some residual carbon, to a melter 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, into the melter, where one or more electrodes operate in a low resistance mode.
