REFRACTORY MIXTURE FOR IRON NOTCHES OF BLAST FURNACE Russian patent published in 2009 - IPC C04B35/66 C04B35/52 

FIELD: metallurgy.

SUBSTANCE: invention relates to refractories industry, particularly to receiving of mixtures, providing for overlapping of iron notches of blast furnaces. Refractory mixture for iron notches of blast furnaces contains coke, clunch and high-temperature peck at following components ratio, wt %: coke 42-58, clunch 26-41, high-temperature peck, containing 43 -54% of volatile, 16-17. Breakup of the received mixture is following, %: fraction more 3 mm - no more 25, fraction less 0.5 mm - no less 50, fraction less 0.09 mm - no less 40, refractory property - no less 1580°C, and humidity 12-20%.

EFFECT: improvement of running ability of mixture and external environment of furnace.
