Abstract

PURPOSE: To prevent the erosion of the hearth part by interposing metal titanium powder in the joints of refractory bricks at the time of brick building of the blast furnace hearth part.
CONSTITUTION: When metal titanium powder is interposed in the vertical and lateral joints 7 of refractory bricks 6 in the longitudinal laid part 4 of the furnace bottom 2 at the time of brick building of the blast furnace hearth part 1, then the metal titanium melts in molten iron along with progression of blast furnace operation and further it becomes TiN, TiC, etc. owing to temperature changes and the changes in nitrogen partial pressure, tnereby crystallizing on the brick surfaces. These crystals grow without being discharged to outside the furnace and form titanium bears, thus covering the brick surfaces. Hence, the hearth part is protected by the titanium bears and the erosion by the subsequent operations is inhibited.
