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.

Description

Technical field: [0001] The invention relates to a wear-resistant material, in particular to a granulation tower water slag ditch used for a blast furnace top gas sealing plate, a cyclone dust collector, a blast furnace water slag system, a sintering machine air box, a sintering machine flue gas circulating pipeline, An anti-corrosion and thermal shock-resistant ceramic wear-resistant material for dust removal pipes and other parts of a sintering machine and a construction and molding method thereof. Background technique: [0002] The flue gas circulation pipeline and cooling air box of the sintering machine are in the atmosphere of high temperature, high negative pressure and high flow rate sintering flue gas for a long time. Also larger. The inner wall of the pipeline has been subjected to a wind speed of 10-15m / s for a long time, together with the sintered ore powder and particles scattered on the trolley, and the erosion of the alkaline gas S, P, N, C and other acidic m...
