Application of Ceramic Coat Synthesized by In-Situ Combustion Synthesis to BF Tuyere Original Research Article

A novel technology of tuyere protection is introduced. The ceramic coat is synthesized by using in-situ combustion process as the internal, external, and nose protecting coat of BF tuyeres. It can effectively protect the tuyeres and reduce heat loss by cooling water. The technology is quick-acting, easy to use, energy-saving and can make tuyeres have long service life. The feasibility of the application of the tuyere ceramic coat is discussed and the energy-saving effect of the tuyere is compared with that of the tuyeres lined with refractory.
