The invention discloses a 12000 T/D kiln outlet special-use castable and belongs to the field of fireproofing materials. The castable inclues the components, by weight, 15-25% of mullite, 10-20% of sillimanite, 25-30% of tabular corundum, 5-10% of strontium titanate powder, 5-8% of zirconium dioxide powder, 1-3% of zinc-aluminium spinel powder, 3-5% of boron nitride, 5-10% of aluminum oxide micro powder, 4-6% of pure calcium aluminate cement, 0.2% of polylactic acid fibers, 0.1% of sodium hexametaphosphate, 0.1% of leucite and 0.1% of C12H14N4O5S2. The castable is improved in thermal shock resistance, high-temperature resistance, volume stability and wear resistance, is high in strength, is improved in the defects that a kiln outlet is not wear-resistant and is poor in thermal shock resistance, and can prolong the service life of a kiln outlet of a cement kiln from about 10 months to 2 years and more.
