CaO-ZrO2-TiO2-BN system was proved to be stable at continuous casting temperature by thermodynamic calculation, no new alumina inclusion would be formed due to this system, it can be used hopefully for anti-clogging SEN materials.

• 通过热力学计算得出CaO-ZrO2-TiO2-BN体系在连铸温度下可以共存,该体系本身不会带来新的Al2O3夹杂,并且有望防止Al2O3 堵塞浸入式水口。
