摘要： A reaction mixture is placed in a furnace comprising a vertical vessel which is transparent to electromagnetic fields and in direct contact with the mixture. High-frequency electric currents are induced in said mixture through the vessel and are of sufficient intensity to start the reaction while the vessel is cooled so as to maintain a solid layer of slag in contact therewith. The reaction mass is maintained molten for a sufficient period of time to cause settling of the metal prior to solidification in situ. The vessel is throttled towards its base.
摘要翻译：将反应混合物置于包括对电磁场透明并与混合物直接接触的垂直容器的炉中。在所述混合物中通过容器诱导高频电流，并且在容器被冷却时具有足够的强度以开始反应，以保持与其接触的炉渣的固体层。将反应物质保持熔融足够的时间以在原位固化之前引起金属沉降。船只朝向其底部。

摘要： CONTINUOUSLY AROUND THE TIP, AND AN AXIALLY EXTENDING PASSAGEWAY THROUGH THE ELECTRODE UTILIZABLE FOR BRINGING INTO THE CRUCIBLE OR INTO THE MELT ORE, OXYGEN, MATTE, IRON BLISTER COPPER, A REDUCING AGENT, OR ANY OTHER MATERIAL ESSENTIAL TO ONE OR MORE OF THE PROCESS OR STEPS. NORMALLY THE ARCING SURFACE IS SPACED FROM THE UPPER SURFACE OF THE MELT, EXCEPT FOR CERTAIN SPECIAL OPERATIONS. REFINED COPPER IS TAPPED FROM THE BOTTOM OF THE CRUCIBLE, AND SLAG AS FORMED IS PERIODICALLY REMOVABLE BY A SPOUT ON THE CRUCIBLE, WHICH MAY BE TITLED.

PROCESS FOR PERFORMING ANY ONE OR MORE, OR ALL OF THE STEPS REQUIRED FOR REDUCING RAW COPPER ORE AND OBTAINING REFINED PURE COPPER, IN WHICH ALL ESSENTIAL STEPS OF THE PROCESS MAY BE CARRIED OUT WITH A SINGLE CRUCIBLE OR LADLE, OR A NUMBER OF CRUCIBLES MAY BE UTILIZED, EACH FOR ONE OR MORE STEPS. FOR HEATING, AN ELECTRIC ARC IS FORMED FROM AND BETWEEN THE UPPERMOST PORTION OF THE CONDUCTIVE MATERIAL IN THE CRUCIBLE, WHETHER ORE, MATTE, BLISTER, OR COPPER, AND AN ELECTRODE IS EMPLOYED HAVING A TIP COMPOSED OF SUBSTANTIALLY PURE COPPER FORMING AN ARCING SURFACE, WITH MAGNETIC FIELD COIL MEANS IN THE TIP TO SET UP A MAGNETIC FIELD TO MOVE THE ARC SUBSTANTIALLY

摘要： A nonconsumable electrode having a supporting structure for a fluid cooled tip forming an arcing surface, having a magnetic field coil therein for setting up a magnetic field at the arcing surface which exerts a force on the arc which causes the arc to move substantially continuously over the arcing surface while heat flux is removed from the arcing surface at a sufficiently high rate to prevent excessive deterioration of the arcing surface as a result of arc action, is utilized in gas heating and metal heating and melting, the arc taking place to a melt composed at least partially of conductive material, to another electrode, or three arcs may be simultaneously produced by three phase alternating current operation.
