Blast-furnace anhydrous stemming and production device thereof
The invention discloses a blast-furnace anhydrous stemming and a production device thereof. The blast-furnace anhydrous stemming is prepared from the following raw materials by weight: 4 to 8% of superfine homogenized bauxite particles, 17 to 20% of brown fused alumina particles, 3 to 7% of white fused alumina powder, 4 to 8% of tabular corundum powder, 2 to 6% of chromite sand powder, 9 to 18% of a carbon material, 4 to 10% of high-purity silicon carbide, 5 to 7% of silicon carbide particles, 10 to 13% of submicron powder, 8 to 12% of soft clay, 2 to 5% of sericite, 2 to 4% of metal silicon powder and 10 to 12% of composite oil. The invention has the following advantages: slag erosion resistance of the anhydrous stemming is increased; resistance of the anhydrous stemming to high-temperature molten iron erosion and wear is strengthened; opening performance and iron slag erosion resistance of the traditionally-used anhydrous stemming are improved; the quality stability of the anhydrous stemming is enhanced; meanwhile, a by-product electrical resistance material of carbon electrode smelting is utilized, so the anhydrous stemming is more beneficial for protection of resources and the environment.
