Aluminum-zirconium brick for transition zone of oversize rotary cement kiln
The invention discloses an aluminum-zirconium brick for an oversize rotary cement kiln transition zone, and belongs to the field of aluminum-zirconium bricks, the aluminum-zirconium brick for the oversize rotary cement kiln transition zone comprises the following raw materials by weight: 46.4-56% of special-grade high bauxite clinker, 8-15% of fused alumina zirconia powder, 2.4-13.5% of zirconium oxide, 9-13.5% of SiC powder, 10-12% of rutile, 5-8% of aluminum dihydrogen phosphate, and the balance of water; the preparation method of the aluminum-zirconium brick for the transition zone of the oversize rotary cement kiln comprises the following specific steps that firstly, raw materials are weighed, specifically, the raw materials with the corresponding mass are weighed according to a weighing formula and a formula, the high-temperature breaking strength of the aluminum-zirconium brick can be improved, and the high-temperature deformation resistance rate of the aluminum-zirconium brick is higher; the aluminum-zirconium brick can be stably supported in a high-temperature environment, deformation of the aluminum-zirconium brick is avoided, the prepared aluminum-zirconium brick is higher in slag permeability resistance, molten slag is not prone to entering the aluminum-zirconium brick, the aluminum-zirconium brick is not prone to generating a metamorphic layer, and the quality of the aluminum-zirconium brick is fully improved.
本发明公开了一种用于特大型水泥回转窑过渡带的铝锆砖，属于铝锆砖领域，该特大型水泥回转窑过渡带的铝锆砖由以下重量百分比的原料组成：特级高铝矾土熟料46.4～56％、锆刚玉粉8～15％、氧化锆2.4～13.5％、SiC粉9～13.5％、金红石10～12％、磷酸二氢铝5～8％，余量为水；该特大型水泥回转窑过渡带的铝锆砖的制备方法具体步骤如下：步骤一：称取原料：依据称量公式和配方称取相应质量的原料，本发明能够提高铝锆砖的高温抗折强度，使得铝锆砖的高温抗变形率更高，使得铝锆砖在高温环境下也可稳定支撑，避免了铝锆砖的变形，且制得的铝锆砖抗渣渗透性更高，使得熔渣不易进入铝锆砖内，使得铝锆砖更加不易产生变质层，充分提高了铝锆砖的质量。
