SYSTEM FOR CHARGING ELECTRIC-ARC FURNACES |
摘要 |
An electric-arc furnace for the smelting and refining of sponge iron has respective electrodes each connected to one phase of the polyphase output of a transformer. The sponge iron is fed to a distributor at a rate determined by the total electrical power consumption of all of the electrodes and is distributed into the furnace through charging doors adjacent each electrode by a compartmented distributor, the capacity of the compartments of which is adjustable in accordance with the electrical consumption of the respective electrical phase. The distributor is a circular receptacle having angularly equispaced openings, each connected via a duct with a charging door, and vanes internally subdividing the receptacle to distribute the sponge iron between the openings in a proportion determined by the angular positions of the vanes. The vanes are adjustable within limits in accordance with the consumption of electrical energy of each electrode.
