Abstract

1,211,957. Determining the C content of a molten metal. FRIED KRUPP G. m. b. H. March 21, 1969 [March 22, 1968], No. 15036/69. Heading C7D. The carbon content of a molten metal (e. g. pig iron or steel) is determined by measuring the oxygen potential of the melt electro-chemically (e.g. using a solid conductor electrolyte such as ZrO2 doped with 15 mol % CaO) and using this value and the temperature of the melt to calculate the oxygen potential thereof from which the carbon content of the melt can be determined from previously established relationships.
