Abstract
A new method has been developed for determining the degree of oxidation in a metallurgical slag. It is based on measuring the equilibrium oxygen partial pressure PO2 with an electrochemical sensor. The basic component is a ceramic element containing boron carbonitride developed at the Institute of Problems of Materials Science, Academy of Sciences of the Ukraine. The rapid response enables one to monitor the state of the slag in the bath and to control the oxidation conditions and provide improved performance in refining steel with slag under various technological conditions.
