Stemming special for blast furnace iron making
The invention discloses stemming special for blast furnace iron making. The stemming special for blast furnace iron making is characterized by being prepared from, by weight, 15-20 parts of 3-1 mm chromium nitride, 5-8 parts of 1-0 mm theron, 10-15 parts of 1-0 mm sericite, 8-15 parts of 0.5-0 mm magnesium iron oxide, 8-13 parts of partial clay 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 powdered carbon, 0-1 part of strontium carbonate powder and 1-2 parts of mid-temperature pitch powder. The stemming can protect the stability of the pore diameter of a tapping hole, changes are not likely to be caused, iron is discharged stably, and meanwhile the using performance and operation performance of the stemming are not lowered in the long-term storage process.
