Method for adjusting the properties of cast iron comprises measuring the oxygen content of the melt. Sufficient magnesium is then added to adjust the oxygen content at 1420[deg] C to 0.005 - 0.2 ppm. An independent claim is included for a sensor for measuring the oxygen content of cast iron melts with an electrochemical measuring cell (6) which contains a solid electrolyte tube whose outer surface has a coating of zirconium dioxide. |
