Interaction of BN ‐ Z r O 2 ‐ S i C Ceramics with Inclusions in Si‐killed Steel
Source abstract
Abstract
Boron nitride ( BN )‐based ceramics are often used as containment refractory in thin‐strip steel production. The interaction of this material ( BN ‐ Z r O 2 ‐ S i C :‐ MYCROSINT ® SO 43) was studied using a steel‐inclusion system in a laboratory setup. Isothermal interaction tests were performed to evaluate the interaction of inclusions with this refractory. It was determined that corrosion of the BN refractory occurs through a dissolution mechanism and it was more severe in contact with steel compared to slag. A thermodynamic model was developed using F act S age to study the change in liquid steel/slag composition with refractory interaction. Thermodynamic predictions were in agreement with the experimental data obtained through isothermal interaction tests.
