Low-thermal-conductivity thermal-shock-resistant wear-resistant brick and production process thereof
The invention provides a low-thermal-conductivity thermal-shock-resistance wear-resistant brick and a production process thereof. The low-thermal-conductivity thermal-shock-resistant wear-resistant brick is prepared from the following raw materials by mass percentage: 20-50% of high bauxite clinker, 5-30% of andalusite particles, 3-15% of andalusite fine powder, 3-10% of zircon sand, 8-12% of refractory mortar, 5-10% of mullite fine powder and 0.5-1.5% of dextrin. The low-thermal-conductivity thermal-shock-resistance wear-resistant brick prepared according to the invention has refractoriness under load of higher than 1600DEG C, normal-temperature compressive strength of higher than 75MPa, an apparent porosity of 13%-16.5%, the 1100DEG C water-cooling thermal shock stability of higher than25 times, and has the advantages of low thermal conductivity coefficient, high heat resistance, and thermal shock resistance and wear resistance.
