| Refractory castables based on alumina-silicate aggregates are commonly used in casting wheel components and launders. In this research the recycling process of waste magnesia chrome bricks for production of refractory castable lining for launders and casting wheels at Iranian Sarcheshmeh Copper Complex (I.S.C.C.) is explained. The smelting plant of ISCC consumes 4000 tons refractory materials and produces 2000 tons waste refractories annually. In order to reduce the environmental pollutions and gain the economical advantages, the recycling of waste refractories proved to be a solution. In ISCC, 800 tons alumina or alumina-silicate refractory castables are used for linings of anode furnace casting wheels and launders annually. In the present work, the spent bricks from reverberatory, converter and anode furnaces were analyzed in term of microstructural changes from hot zone to the cold end to evaluate the changes in texture and chemical composition. Different formulations based on recycled magnesia chrome aggregates and various particle size distribution and cement content were tested. Economic recycled magnesia chrome refractory mixture was prepared after crushing and sizing the non-deteriorated regions of wasted bricks. After evaluation of physical and mechanical properties of samples, one ton refractory castable was prepared and successfully installed in the casting wheel. |
