High-strength, high-thermal-shock and ultralow-thermal-conductivity corundum-mullite light furnace cover brick
The invention discloses a high-strength, high-thermal-shock and ultralow-thermal-conductivity corundum-mullite light furnace cover brick, relates to the technical field of bricks, and aims to solve the problems that an existing corundum-mullite light furnace cover brick is unreasonable in ingredient, low in product strength, high in thermal conductivity, prone to hurting people in the using process, short in service life, prone to causing unnecessary economic loss and poor in using effect. According to the technical scheme, the high-temperature-resistant refractory brick is prepared from raw materials in parts by weight as follows: 50-55 parts of special-grade high-alumina bauxite granules, 5-10 parts of fused corundum granules, 10-15 parts of synthetic mullite powder, 5-10 parts of aluminum oxide powder, 3-5 parts of ferric oxide, 1-3 parts of silica powder, 1-2 parts of sodium hexametaphosphate and 3-5 parts of combined clay. The invention has the advantages of reasonable design, wide raw material source, low price, effective reduction of the production cost and prolongation of the service life by adding a proper amount of alumina and ferric oxide to improve the strength and thermal vibration and reduce the thermal conductivity, and is suitable for popularization and use.
本发明公开了高强度高热震超低导热刚玉莫来石轻质炉盖砖，涉及砖块技术领域，针对现有的刚玉莫来石轻质炉盖砖，配料不够合理，产物强度低热导较高，在使用过程中易伤人，使用寿命较短，易造成不必要的经济损失，使用效果差的问题，现提出如下方案，包括以下重量份的原料：特级高铝矾土颗粒料50～55份、电熔刚玉颗粒料5～10份、合成莫来石粉10～15份、氧化铝粉末5～10份、氧化铁3～5份、硅微粉1～3份、六偏磷酸钠1～2份与结合黏土3～5份。本发明设计合理，通过加入适量的氧化铝与氧化铁，提高了强度与热振，降低了热导，原料广泛，价格低廉，有效降低了生产成本且提高了使用寿命，适合推广使用。
