Aluminum-zirconium brick for transition zone of super-huge type rotary cement kiln
The invention provides an aluminum-zirconium brick for a transition zone of a super-huge type rotary cement kiln. The brick is prepared by taking special-grade high-alumina bauxite clinker and fused alumina zirconia as aggregates, taking silicon carbide powder, andalusite powder and the like as matrixes and adding a proper amount of additives. The brick has excellent properties of high strength, low thermal conductivity, high-temperature wear resistance, high refractoriness under load, erosion resistance, thermal shock resistance and the like, meets the use requirements of the refractory material for the transition zone of the large dry-process cement rotary kiln, can effectively protect the barrel, has long service life, solves the problem of environmental pollution caused by hexavalent chromium in the cement industry, and is simple in preparation process and high in cost performance.
本发明提出一种用于特大型水泥回转窑过渡带的铝锆砖，以特级高铝矾土熟料、锆刚玉为骨料，以碳化硅粉、红柱石粉等为基质，加入适量外加剂制成。本发明具有高强度、低导热、高温耐磨、高荷重软化温度、抗侵蚀、抗热震等优异性能，满足大型干法水泥回旋窑过渡带耐火材料的使用要求，能够有效保护筒体，使用寿命长，同时解决水泥工业六价铬对环境的污染，同时制备工艺简单，性价比高。
