A Steelmaking slag oxygen activity sensor; experiences and observations

摘要

The importance of slag engineering for optimizing primary and secondary steelmaking processes has progressed over the years to the point of slag custormization. These "designer" slags. whether added as a singular material, or resulting from "conditioning" existing slags, or formed in combination with the products of oxygen refining, all have a common denominator. They are not static chemical systems independent of the metal they cover nor the refractory lined vessels in which they are contained. A constant flux of material is exchanged between the slag and the metal systems. An action taken to achieve a result in the metal can be quantified by observing its influence in the slag.
