High-strength high-alumina brick and preparation method thereof
The invention relates to a high-strength high-alumina brick and a preparation method thereof, and belongs to the field of refractory materials. The high-strength high-alumina brick is prepared from, by weight, 55-70 parts of homogenized material particles of which the Al2O3 content is greater than or equal to 80% and less than or equal to 98% and the Fe2O3 content is less than or equal to 2%, 25-30 parts of homogenized material powder of which the Al2O3 content is greater than or equal to 80% and less than or equal to 90% and the Fe2O3 content is less than or equal to 2%, 4-6 parts of aluminapowder of which the Al2O3 content is greater than or equal to 98% and less than or equal to 100% and the Fe2O3 content is less than or equal to 0.2%, 3-6 arts of silicon carbide powder of which the SiC content is larger than or equal to 95% and smaller than or equal to 98% and the Fe2O3 content is smaller than or equal to 0.8%, and white mud of which the Al2O3 content is larger than or equal to 34% and smaller than or equal to 60% and the Fe2O3 content is smaller than or equal to 1.5%. The high-strength high-alumina brick can effectively improve the refractoriness under load of a traditional high-alumina brick.
本发明涉及一种高强度高铝砖及其制备方法，属于耐火材料领域制备领域，本发明所述的一种高强度高铝砖，由以下重量份数的原料制成，80％≤AlO≤98％且FeO≤2％的均化料颗粒55‑70份，80％≤AlO≤90％且FeO≤2％的均化料粉25‑30份，98％≤AlO≤100％且FeO≤0.2％的氧化铝粉4‑6份，95％≤SiC≤98％且FeO≤0.8％的碳化硅粉3‑6份，34％≤AlO≤60％且FeO≤1.5％的白泥13‑15份，本发明所述的高强度高铝砖可有效提高传统高铝砖的荷重软化温度。
