Abstract
A method is provided for influencing the properties of cast iron by adding magnesium to the cast iron melt and measuring the oxygen content of the cast iron melt. Magnesium is added to the cast iron melt until the oxygen content of the cast iron melt is approximately 0.005 to 0.2 ppm at a temperature of approximately 1,420° C. A sensor for measuring the oxygen content in cast iron melts contains an electrochemical measuring cell containing a solid electrolyte tube.
