Composite aluminum-silicon carbide brick and preparation method thereof
The invention relates to a composite aluminum silicon carbide brick and a preparation method thereof, and belongs to the field of refractory materials. The composite aluminum silicon carbide brick isprepared from, by weight, 5-10 parts of brown fused alumina containing 95-98% of Al2O3 and 0.3% or less of Fe2O3, 60-80 parts of a homogenized material containing 88-98% of Al2O3 and 2% or less of Fe2O3, 5-10 parts of alumina powder containing 98-99% of Al2O3 and 0.2% or less of Fe2O3, 10-20 parts of silicon carbide powder containing 95-98% of SiC and 0.8% or less of Fe2O3, and 8-15 parts of whitemud containing 34-40% of Al2O3 and 1.5% or less of Fe2O3. The load softening temperature of a traditional silicon brick can be effectively improved by the composite aluminum-silicon carbide brick.
本发明涉及一种复合铝碳化硅砖及其制备方法，属于耐火材料领域制备领域，其由以下重量份数的原料制成，95％≤AlO≤98％且FeO≤0.3％的棕刚玉5‑10份，88％≤AlO≤98％且FeO≤2％的均化料60‑80份，98％≤AlO≤99％且FeO≤0.2％的氧化铝粉5‑10份，95％≤SiC≤98％且FeO≤0.8％的碳化硅粉10‑20份，34％≤AlO≤40％且FeO≤1.5％白泥8‑15份。本发明复合铝碳化硅砖可有效提高传统硅砖的荷重软化温度。
