METHOD FOR INFLUENCING THE PROPERTIES OF CAST IRON

摘要

The invention relates to a method for influencing the properties of cast iron by adding magnesium to the cast iron melt, the oxygen content of the cast iron melt being measured and magnesium being supplied to the cast iron melt until the oxygen content of the cast iron melt at a temperature of approximately 1420°C is approximately 0.005 to 0.2 ppm. The invention also relates to a sensor for measuring the oxygen content in cast iron melts, comprising an electrochemical measuring cell that has a solid electrolyte tube.
