In this paper,the recycling status of carbon-containing refractories after use is summarized,and some research achievements of recycling of magnesia-carbon refractories,alumina-magnesia-carbon refractories,alumina-carbon refractories and alumina-silicon carbide-carbon refractories after use are mainly introduced.The recycling of carbon-containing refractories after use can not only effectively reduce the production cost,but also protect the environment and bring some economic benefits.
