Thermal-shock-resistant high-alumina brick and preparation method thereof
The invention discloses a thermal-shock-resistant high-alumina brick. The thermal-shock-resistant high-alumina brick is prepared from the following raw materials in parts by weight, 20-30 parts of mullite particles, wherein a use ratio of Al2O3 is greater than or equal to 70% and less than or equal to 90% and a use ratio of Fe2O3 is less than or equal to 2%, 40-60 parts of flint clay, wherein a use ratio of Al2O3 is greater than or equal to 45% and less than or equal to 80% and a use ratio of Fe2O3 is less than or equal to 1%, 10-20 parts of high-alumina powder, wherein a use ratio of Al2O3 isgreater than or equal to 70% and less than or equal to 90% and a use ratio of Fe2O3 is less than or equal to 2%, 1-8 parts of light-burned magnesia powder, and 5-15 parts of white mud, wherein a useratio of Al2O3 is greater than or equal to 34% and less than or equal to 60% and a use ratio of Fe2O3 is less than or equal to 1%. The high-alumina brick is high in thermal shock resistance stability,and the refractoriness under load of a traditional high-alumina brick is improved.
本发明公开了一种抗热震高铝砖，由以下重量份数的原料制成，由70％≤Al2O3≤90％且Fe2O3≤2％的莫来石颗粒20‑30份，45％≤Al2O3≤80％且Fe2O3≤1％的焦宝石40‑60份，70％≤Al2O3≤90％且Fe2O3≤2％的高铝粉10‑20份,轻烧镁砂粉1‑8份，34％≤Al2O3≤60％且Fe2O3≤1.5％的白泥5‑15份。本发明的抗热震稳定性高且提高了传统高铝砖的荷重软化温度。
