A tuyere assembly for use in metallurgical vessels includes a tubular metallic tuyere housing which is cast in a book of refractory material. When the tuyere block is installed in a metallurgical vessel, a tuyere is inserted within the tubular tuyere housing and the space between the tuyere assembly and the housing sealed with a suitable refractory material. After a significant portion of the tuyere assembly has burned away during metallurgical operations, the tuyere may be withdrawn from the tuyere housing and a new tuyere substituted. Any refractory lining which has burned away in the vicinity of the new tuyere may be built up with a chemically bonded gunning mixture which sets to form a dense refractory material around the tuyere assembly.
