Extending the Life of Blast-Furnace Air Tuyeres

Air tuyeres are the most thermally stressed components of blast furnaces; therefore, extending their life is of importance. Operating experience suggests that the intensification of cooling alone does not prevent burnout of tuyeres. In this connection, the VNIIMT presents design developments that co...

Description
Summary:Air tuyeres are the most thermally stressed components of blast furnaces; therefore, extending their life is of importance. Operating experience suggests that the intensification of cooling alone does not prevent burnout of tuyeres. In this connection, the VNIIMT presents design developments that combine advanced cooling intensification solutions and thermal insulation protection, which can significantly extend the service life of air tuyeres.
