Small blast furnace ironmaking special-purpose stemming
The invention discloses small blast furnace ironmaking special-purpose stemming. The small blast furnace ironmaking special-purpose stemming comprises, by weight, 15-20 parts of chromium nitride with particle sizes of 3-1mm, 5-8 parts of sialon with particle sizes of 1-0mm, 10-15 parts of sillimanite with particle sizes of 1-0mm, 8-15 parts of iron magnesium oxide with particle sizes of 0.5-0mm, 8-13 parts of clay-like powder, 3-7 parts of cobalt aluminum oxide powder, 5-10 parts of cutting powder, 7-25 parts of crystalline flake graphite powder, 5-10 parts of composite carbon powder and 1-2 parts of middle temperature asphalt powder. The stemming can keep iron outlet size stability, prevent easy size change, guarantee iron outlet stability, and has stable usage performances and operation performances in long-term storage.
