Low-pollution preparation process of high-alumina bauxite clinker
The invention discloses a low-pollution preparation process of high-alumina bauxite clinker, and belongs to the field of high-alumina bauxite. The low-pollution preparation process comprises the following steps: uniformly paving a high-alumina bauxite raw material on a kiln car, pushing the kiln car into a kiln from a kiln head, entering a preheating zone, preheating the high-alumina bauxite raw material in the preheating zone, feeding the preheated kiln car into a calcining zone, heating and calcining the high-alumina bauxite raw material through the combustion equipment arranged on the two sides of the kiln, and continuing feeding the kiln car into the cooling zone, so that the problem that the high-alumina bauxite clinker is easy to crack when being used as a refractory material is solved; dispersed SiO2 can absorb impact energy of microcracks and prevent the cracks from expanding; nano SiO2 reacts with B203 at a high temperature to generate a glass phase; a system starts to be converted from an organic structure to an inorganic structure, and volume expansion occurs, so that volume shrinkage generated during resin thermal cracking can be effectively inhibited, the microcracks generated in ceramic can be healed, the completeness of a ceramic interface is ensured, and the purpose of inhibiting crack generation is achieved.
本发明公开了一种高铝矾土熟料低污染制备工艺，高铝矾土领域，通过将高铝矾土原料均匀铺设在窑车上，将窑车从窑头推入窑内，进入预热带，在预热带高铝矾土原料预热，将预热后的窑车送入煅烧带，利用设置在窑两侧的燃烧设备对高铝矾土原料加热锻烧，窑车继续送入冷却带，解决了高铝矾土熟料在被用作耐火材料时，易产生裂纹的问题；分散的Si02可吸收微裂纹的冲击能，阻止裂纹扩大，高温时纳米Si02与B203反应生成玻璃相，体系开始从有机结构向无机结构发生转变，出现体积膨胀，可以有效地抑制树脂热裂解时产生的体积收缩，有利于愈合陶瓷中产生的微裂纹，保证陶瓷界面的完整性，从而达到抑制裂纹产生的目的。
