The invention discloses a wear-resistant ceramic material for repairing a dry quenching furnace bracket support part. The wear-resistant ceramic material for repairing the dry quenching furnace bracket support part comprises 20%-40% of fused mullite particles with the particle size ranging from 5 mm to 3 mm, 10%-25% of fused dense corundum with the particle size ranging from 8 mm to 3 mm, 5%-15% of fused alumina zirconia particles with the particle size ranging from 3 mm to 1 mm, 3%-20% of sintered alumina particles with the particle size ranging from 1 mm to 0 mm, 5%-20% of composite ceramic nano powder, 3%-15% of aluminate cement, 1%-5% of composite antiknock agents, 0.25% of composite water reducers and 4%-6% of industrial softened water, wherein the composite antiknock agents adopt two or more of water-soluble explosion-proof fibers or aluminum lactate or aluminum metal or stainless steel fibers, the water reducers adopt two or more of sodium polyphosphate or sodium tripolyphosphate or sodium hexametaphosphate or sodium humate or water glass. The wear-resistant ceramic material is used for repairing the dry quenching furnace bracket support part, the integral structure is completed after forming in conducted, abrasion loss is small, the creep value is low, very high strength and toughness are achieved, and shock resistance and abrasion resistance are better.
