Special taphole clay for blast furnace ironmaking
The invention discloses special taphole clayfor blast furnace ironmaking. The special taphole clay is characterized by being prepared from the following components in parts by weight: 15-20 parts of 3-0mm chromium nitride, 5-8 parts of 1-0mm SiAlON, 10-15 parts of 1-0mm sillimanite, 8-15 parts of 0.5-0mm magnesium-iron oxide, 8-13 parts of slight clayey silt, 3-7 parts of cobalt aluminum oxide powder, 5-10 parts of cutting powder, 7-25 parts of flake graphite powder, 5-10 parts of composite carbon powder, 0-1 part of strontium carbonate powder and 1-2 parts of medium-temperature pitch powder. By using the tapping hole clay, the aperture of a tapping hole can be kept stable and is not easily changed, and the tapping hole can stably tap; in addition, the service and operation performances of the tapping hole clay are not lowered in the long-term storage process.
