Low-thermal-conductivity high-strength anti-scouring riser brick and preparation method thereof
The invention discloses a low-thermal-conductivity high-strength anti-scouring riser brick which comprises the following raw materials in percentage by weight: 87-92% of high-alumina bauxite; 0-8% ofwhite mud; 0-1% of zirconite powder; 4.5-6% of lignin. The invention further discloses a preparation method of the low-thermal-conductivity high-strength anti-scouring riser brick. The preparation method comprises the following steps: a, mixing the high-alumina bauxite, the white mud and the zircon powder in proportion and then crushing; b, mixing the mixed particles obtained in the step a with alignin aqueous solution in proportion to obtain a mixed raw material; c, pressing the mixed raw material in the step b into a green brick; and d, sintering the green brick obtained in the step c at 1450 DEG C for 2 hours to obtain the low-thermal-conductivity high-strength anti-scouring riser brick. According to the low-heat-conductivity high-strength anti-scouring riser brick, the riser brick hasthe characteristics of low heat conductivity coefficient, good heat stability and strong anti-scouring capability, and the service life of the riser brick is as long as 5-7 times. The invention further provides a processing method of the low-thermal-conductivity high-strength anti-scouring riser brick. The processing method has the characteristics of simplicity, convenience and short processing period.
