  • Method of controlling steel making process under atmospheric pressure
    Patent number: 4251270
    Abstract: Method of controlling steel making process under atmospheric pressure, comprising forming an intimate mixture of an exhaust gas and a measured quantity of a reference gas; mass spectrometrically monitoring a sample of the mixture for the ionization currents for selected peaks with which the CO, CO.sub.2, N.sub.2 and reference gas in the sample are concerned; determining the rate or amount of decarburization of the molten steel from the measured value of the quantity of the reference gas in the mixture and the measured values of the ionization currents, and; controlling the process according to the determined value of the rate or amount of decarburization.
    Type: Grant
    Filed: August 30, 1978
    Date of Patent: February 17, 1981
    Assignee: Nisshin Steel Co., Ltd.
    Inventors: Fumio Hoshi, Yuzo Saita, Akira Fujisawa
