Spinel brick for rotary kiln and preparation method thereof
The invention discloses a spinel brick for a rotary kiln and a preparation method of the spinel brick, and belongs to the technical field of rotary kiln preparation, and the spinel brick for the rotary kiln is produced by taking inked corundum and medium-grade magnesia as main raw materials, adding composite metal powder and taking liquid phenolic resin as a binding agent. The specific preparation method comprises the following steps: mixing and grinding ink corundum, medium-grade magnesia, fused magnesia fine powder, composite metal powder, fused magnesium aluminate spinel powder and an additional binding agent in different specifications to obtain a mixed and ground material; and molding the mixed and ground material by a brick press, naturally drying a qualified molded product, drying the qualified molded product in a tunnel drying kiln according to specific drying conditions, and sorting a qualified product after drying to obtain the spinel brick for the rotary kiln. The spinel brick for the rotary kiln prepared by the invention has the advantages of high strength, good thermal shock resistance, good permeability resistance, good erosion resistance, long service life and the like, and can be widely applied to high-temperature zone parts of the rotary kiln.
本发明公开了一种回转窑用尖晶石砖及其制备方法，属于回转窑制备技术领域，本发明采用墨钢玉、中档镁砂为主要原料，通过添加复合金属粉，并以液体酚醛树脂为结合剂生产回转窑高温带砖，具体的制备方法是是将不同规格的墨钢玉、中档镁砂、电熔镁砂细粉、复合金属粉、电熔镁铝尖晶石粉以及外加结合剂进行混碾，得到混碾料；再将混碾料进行压砖机成型，合格成型制品自然干燥后进入隧道干燥窑内按特定的干燥条件进行干燥，干燥后拣选合格的制品即为回转窑用尖晶石砖，本发明制备的回转窑用尖晶石砖具有强度高、热震稳定性好、抗渗透性好、抗侵蚀性好、使用寿命长等优点，可广泛适用于回转窑高温带部位。
