ABSTRACT:
A replaceable liner assembly for a blast furnace tuyere comprises a tubular, metallic liner which fits within the tuyere and a plurality of layers of refractory fiber paper sandwiched between the tubular liner and the inside surface of the tuyere. There are gas-tight seals between the liner and the tuyere at opposite ends thereof to prevent gas from entering the space occupied by the refractory fiber paper. The liner is composed of a metal which has a good resistance to oxidation and a lower thermal conductance and higher melting point than the metal of which the tuyere is composed.
