Permeation-resistant corrosion-resistant pouring material
The invention discloses a permeation-resistant corrosion-resistant pouring material. The permeation-resistant corrosion-resistant pouring material comprises, by weight, 40-49% of fused alumina zirconia, 12-20% of zirconium silicate powder, 6-7% of alumina powder, 12-25% of white corundum powder, 1-1.5% of silicon powder, 4-5% of dextrin, and 0.2-0.3% of sodium tripolyphosphate. The fused alumina zirconia comprises parts with different particle sizes, wherein a ratio of the part with particle sizes of 6-8mm in fused alumina zirconia is 15-20wt%, a ratio of the part with particle sizes of 4-6mm in fused alumina zirconia is 20-25wt%, a ratio of the part with particle sizes of 2-4mm in fused alumina zirconia is 30-35wt%, a ratio of the part with particle sizes of 1-2mm in fused alumina zirconia is 10-15wt% and a ratio of the part with particle sizes of 0-1mm in fused alumina zirconia is 5-10wt% and the used white corundum powder is W20 type white corundum powder. The fused alumina zirconia is used as a main material so that good melt corrosion resistance is obtained, white corundum powder is used as a concretion material so that molded base strength is high, stability is good and local penetration caused by thawing is avoided, and silicon powder is used as a pouring base so that refractoriness is good, chemical stability is good and furnace inner atmosphere influence is avoided.
