Abstract:
Refractories, materials used in furnace linings and industrial equipment, are directly or indirectly, positively or negatively, associated with range of environmental problems. When discussing the influence of refractories on the environment, one should consider: aspects related to the global environment, local environment, work environment and the generation of waste. Refractory wastes are historically disposed of as waste in industrial landfills. However, some of the refractory materials used have the potential to be recycled, contributing to environmental and economic sustainability. The addition of recycled aggregates of system Al2O3-SiC on refractory castables of the Al2O3-SiC-C system were evaluated for the development of refractory recycling technology after use. In general, the results of the dynamic slag test indicated the potential of the use of recycled aggregates of charging ladle, torpedo ladle car and slide gate plates.
