Abstract

1,111,264. Determining oxygen content of molten metal electrically. YAWATA IRON & STEEL CO. Ltd. May 4, 1965 [May 6, 1964], No. 18682/65. Heading G1N. The oxygen content of molten metal is measured by means of a standard electrode 4, 5, 6 (Fig. 1) used as a reference in measuring the oxygen potential and a metallic electrode 8, which project through the bottom wall of a crucible 2 and contact the melt, and are connected to a recording meter 9. The standard electrode comprises a permeable shell 4, acting as an intermediate electrolyte, (of sintered magnesia, zirconia, alumina, silica, beryllia or thoria), which may be filled with powdered material 5 of constant low oxygen potential (e. g. graphite or silicon carbide), and a conductive rod 6 (of graphite, tungsten, silicon carbide). The crucible contents may be heated by a h. f. energized induction coil 1. The electrode 8 may be of iron tungsten or nickel surrounded by refractory material. In an alternative embodiment Fig. 3 (not shown) the standard electrode is constituted by an electrocast magnesia plug (4), which is used simultaneously as the intermediate electrolyte and as the standard electrode material and has a conductive rod of platinum or nickel embedded therein which is connected to the recording meter. When used in an industrial furnace Figs. 5, 7 (not shown) there may be a number of the standard electrodes (such as the Fig. 3 embodiment) used, each electrode being disposed in the furnace bottom wall at a different depth below the surface of the furnace adjacent the melt. As the furnace wall erodes in time then succeeding electrodes are selectively switched into a measuring circuit according to which one is exposed at the said surface.
