The invention discloses an anti-erosion alkali-resistant brick which comprises the following raw material components: aluminum aggregate, powder and water, the aluminum aggregate comprises calcined bauxite; the powder comprises chromium ore, high aluminum powder, Guangxi white mud and iron powder; and the raw material components also comprise electroceramic aggregate. The invention has the following beneficial effects: the weight of the prepared brick can reach 20 kg, and good erosion resistance and alkali resistance can still be maintained; according to the invention, two kinds of calcined bauxite with different particle sizes are preferably used, and are mixed according to a proper ratio, so that coarse density can be avoided, the dispersity and uniformity among particles can be improved, and after the large brick is molded, the density is effectively improved and the erosion resistance is improved on the microscopic scale; the proportion adopted by the invention can be beneficial to improving the pressure resistance and thermal shock resistance of the refractory brick, and the influence of alkali resistance reduction caused by high aluminum content can be made up by adding the electroceramic aggregate into the component powder, so that the alkali resistance of the refractory brick can still reach 95% or above.
本发明公开了一种抗侵蚀耐碱砖，其原料组分中包括有铝骨料、粉料和水；所述铝骨料包括有熟铝矾土；所述粉料包括有硌矿、高铝粉、广西白泥和铁粉；原料组分中还包括有电瓷骨料。本发明的有益效果是：本发明制备得到的砖型重量可达到20公斤，仍旧能够保持较好的抗侵蚀性和耐碱性；本发明优选的使用两种不同粒径的熟铝矾土，且采用适宜的配比混用，有利于避免粗密，有利于提高粒子间的分散性和均匀性，使得大砖成型后，在微观上密度有效提高，抗侵蚀性提高；本发明所采用的配比能够有利于提高耐火砖的耐压和热震性，而在组分粉料中添加电瓷骨料能够弥补由于高铝含量带来的耐碱性降低的影响，使得耐火砖的耐碱性仍旧能够达到95%以上。
