Abstract

The invention discloses an anticorrosion thermal shock-resistant ceramic wear-resistant material. The anticorrosion thermal shock-resistant ceramic wear-resistant material comprises 30% of brown fused alumina particles with granularity of 5-3mm, 15% of fused alumina zirconia particles with granularity of 3-1mm, 10% of silicon carbide particles with granularity of 1-0.2mm, 10% of sintered alumina with granularity of 1-0.1mm, 10-20% of composite ceramic nanometer powder, 5-30% of aluminate cement, 1-5% of a compound antiknock agent, 0.25% of a compound water reducer and 5-8% of industrial softened water. The compound antiknock agent comprises two or more of water-soluble explosion-proof fibers, aluminum lactate, metal aluminum and stainless steel fibers. The compound water reducer comprises two or more of sodium polyphosphate, sodium tripolyphosphate, sodium hexametaphosphate, sodium humate and sodium silicate. The anticorrosion thermal shock-resistant ceramic wear-resistant material is used for a blast furnace roof gas sealing plate, a cyclone dust collector, a granulation tower water granulated slag trench of a blast furnace granulating slag system, sintering machine bellows, a sintering machine flue gas cycle pipe and a sintering machine dedusting pipe and has good wear resistance, high temperature resistance, corrosion resistance and thermal shock stability.
