The current exploitation situation of waste refractories was summarized. The resource utilization of waste refractories in foreign advanced steel enterprises was introduced, namely, waste MgO refractories as steelmaking flux instead of light burned dolomite refractories, and waste Al2O3 refractories as refining flux instead of bauxite refractories. Finally, the development and research direction of the resource utilization of waste refractories were prospected.
