Some problems in electric furnace operation: Improvements in ferro-alloy electric furnaces of high power input: Development of the large electric melting furnace

J. A. Seede: I remember distinctly a large smelting furnace making ferro-alloys in which the condition existed that Mr. Andreae points out, i.e., the charge surrounding the left hand electrode, looking at the furnace from the transformer, indicated that the temperature was too low to produce the required metallurgical action while the charge around the other electrodes indicated that the temperature was high and the metallurgical conditions satisfactory. Such unbalanced metallurgical conditions never produce satisfactory operation and no one had made, or has made to my knowledge, such a thorough analysis as the author has made in this paper.
