Refractory brick produced from aluminum ash and preparation process thereof
The invention belongs to the technical field of building materials, and particularly relates to a refractory brick produced from aluminum ash and a preparation process thereof. The refractory brick produced from the aluminum ash is prepared by taking the aluminum ash as a main raw material and adding a high-temperature binding agent and a forming binding agent as auxiliary materials. According to the invention, the aluminum ash in the electrolytic aluminum industry can be effectively consumed, on one hand, the problem of environment-friendly discharged waste disposal of electrolytic aluminum enterprises is solved, on the other hand, efficient utilization of resources is realized, on the other hand, a refractory material product with a good market prospect is provided, and the economic benefit, the environment-friendly benefit and the social benefit are very remarkable; meanwhile, the problem of fluorine pollution of the aluminum ash can be well solved, fluorine and aluminum-silicon-calcium in the aluminum ash form fluorosilicate glass with stable chemical properties at high temperature, and fluorine is not dissolved out any more.
本发明属于建筑材料技术领域，具体涉及一种铝灰生产的耐火砖及其制备工艺，所述的铝灰生产的耐火砖，以铝灰为主要原料，添加高温结合剂和成型粘结剂为辅料制得。本发明可有效消耗掉电解铝行业的铝灰，一方面解决了电解铝企业环保排放废料处置的问题，一方面实现了资源的高效利用，再一方面提供了市场前景良好的耐火材料产品，经济效益、环保效益、社会效益十分显著；同时可以很好的解决铝灰的氟污染问题，高温下铝灰中的氟和铝硅钙形成化学性质稳定的氟硅酸盐玻璃，氟不再溶出。
