Embodiment 1
[0020] The present invention is an improved carbonaceous mud for repairing the hearth of a blast furnace, which is composed of anthracite powder, graphite powder, electrode powder and coal tar, and the weight percentage of the anthracite powder in the carbonaceous mud is 26% , the weight percentage of the graphite powder in the carbonaceous mud is 6%, the weight percentage of the electrode powder in the carbonaceous mud is 14%, and the balance is the coal tar. A kind of production technology of the improved carbonaceous mud that is used for repairing blast furnace hearth of the present invention is: at first weigh the weight of each component according to weight ratio, secondly, carry out dry mixing with anthracite coal powder, graphite powder and electrode powder, fully After mixing, coal tar is added for kneading to obtain the improved carbonaceous slurry for repairing the hearth of the blast furnace. This product is suitable for use when the gaps in the lining of the blast f...
