Refractory brick for laterite-nickel ore rotary kiln and preparation method and application thereof
The invention provides a refractory brick for a laterite-nickel ore rotary kiln as well as a preparation method and application thereof, and relates to the technical field of shaped refractory materials. The refractory brick for the laterite-nickel ore rotary kiln is mainly prepared from a mixed particle material formed by calcium hexaluminate particles and fused zirconia corundum particles, a mixed fine powder material formed by calcium hexaluminate fine powder, corundum fine powder, clay fine powder and zirconite fine powder, a binder and water. Through cooperation of the raw materials, the refractory brick for the laterite-nickel ore rotary kiln has the characteristics of high high-temperature mechanical strength, low heat conductivity coefficient, good thermal shock resistance and high erosion resistance and penetration resistance, and the problems that the existing refractory brick for the laterite-nickel ore rotary kiln is insufficient in high-temperature mechanical property and low in erosion resistance and penetration resistance are solved. In addition, the required raw materials are wide in source, easy to obtain, free of toxic and harmful components and environmentally friendly. The invention also provides a preparation method of the refractory brick for the laterite-nickel ore rotary kiln, and the preparation process is simple, energy-saving and environment-friendly.
本发明提供了一种红土镍矿回转窑用耐火砖及其制备方法和应用，涉及定形耐火材料技术领域。该红土镍矿回转窑用耐火砖主要由六铝酸钙颗粒和电熔锆刚玉颗粒形成的混合颗粒料，六铝酸钙细粉、刚玉细粉、黏土细粉和锆英石细粉形成的混合细粉料以及粘结剂和水制成；通过上述各原料的配合，使得该红土镍矿回转窑用耐火砖具有高温力学强度大、导热系数低、抗热震性能好、抗侵蚀和抗渗透能力强的特点，改善现有红土镍矿回转窑用耐火砖高温力学性能不足、抗侵蚀和抗渗透能力低的问题。另外，本发明所需原料来源广泛，易于获得，且无毒害组分，对环境友好。本发明还提供了上述红土镍矿回转窑用耐火砖的制备方法，制备工艺过程简单，节能环保。
