微碳铬铁精炼电炉的零电位线埋设及其特性

EMBEDDED ZERO POTENTIAL WIRE IN THE FERROCHROMIUM REFINING FURNACE AND ITS FEATURES

本文论述了微碳铬铁精炼电炉采用经砖砌炉时，在不影响产品质量的前题下，埋入一条导电的镁碳砖作为零电位线，以便准确地测定三相电极的二次电压。经对比实验表明，与炉壳作为零电位线相比差别不大。

Abstract The paper discusses the embeddability of zero potential wire in the magnesia brick lining of a Fe-Cr refining furnace. The practice shows that the conducting magnesia-carbon brick embedded in the hearth may be used as zero potential wire in the measurement of secondary voltage of the electrodes. The result of the contrast that is similar to that obtained with the furnace shell as zero potential.
