Description:
Boron nitride (BN)-based ceramics are often used as containment refractory in thin-strip steel production. The interaction of this material (BN-ZrO 2 -SiC:-MYCROSINT ® SO43) 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 FactSage 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.
