Abstract
266,658. Croese, D. Aug. 27, 1925. Electrode and resistance furnaces.-A process for the production of metals or alloys from finely divided ores comprises treating the ore for the removal of impurities, and then causing the treated material to fall by gravity through a furnace divided into a number of chambers in which the material is first preheated and then passes freely through a plurality of arcs under non- oxidizing conditions for the purpose of melting and reduction, further heat treatment being finally applied to separate the metal from the slag. In the case of ironsand the preliminary operation may be effected by passage through a magnetic separator. The ore is fed to the furnace from a hopper 2 by a conveyer 3 through an air tight casing 5. The furnace 1 is lined with firebrick 11 and comprises a preheating chamber 7 and arc chambers 12 fitted with electrodes 12. The furnace 1 is stationary and is seated in a lifting crucible 16. Gates 24, 25 permit isolation of the crucible when tilting. The chamber 7 is heated by waste gases which escape by a pipe 37, but it may be electrically heated. The crucible may be heated by electrodes or resistances or by mixing the waste gases with air and burning the mixture around the crucible. An electromagnet may be arranged on a framework under the crucible to deflect the arcs therein. The waste gases may be led to a cooling and scrubbing apparatus and from thence passed into a storage for subsequent use in the prime mover of an electric generating plant. The chambers in the furnace 1 are separated by graphite members 9 having a conical throat and co-operating with double conical graphite baffles 6 mounted on graphite arms 8 to break up the falling material. An inert gas may be introduced into the furnace through the lowest arc chamber. When metallic oxides are to be treated they are mixed with coke, anthracite, or other reducing agent before introduction to the hopper 2. Alternatively the reducing agent is supplied to the crucible. When treating ironsand the percentage of titanium present in the steel is dependent on the time that the metal is heated in the crucible. Data of a particular furnace applied to the reduction of ironsand are given in the Specification.
