PRACTICE OF PROTECTING BF HEARTH BY ADDING V-Ti BEARING MATERIALS AT SMMC

Based on practice of protecting BF hearth at Shanghai Meishan Metallurgical Co.(SMMC)in recent more than 4 years, author indicated that when thermal flow intensity of hearth is larger and erosion of hearth lining is serious at the last stage of campaign, adding V-Ti bearing materials to hearth and carrying out relative measures are necessary to maintain higher production under safe operation of blast furnace. Due to the careful protecting of BF hearth high production and long campaign have been achieved. Furthermore, the paper discussed the effect of adding V-Ti bearing materials on protection of BF hearth.
