Electric smelting forsterite refractory brick for cement rotary kiln firing zone
The invention relates to an electric smelting forsterite refractory brick for a cement rotary kiln firing zone, which belongs to the field of kiln lining high-temperature-resistant materials, and thebrick is prepared by premixing, mixing, forming, drying and sintering electrically-fused forsterite sand with a particle size of 5-3mm, electrically-fused forsterite sand with the particle size of 3-1mm, electrically-fused forsterite sand with the particle size of 1-0mm, electrically-fused forsterite sand with the particle size of 200 meshes and additional paper pulp waste liquid binder. Accordingto the method, the magnesite tailings are prepared in an electric smelting mode, occupation of land resources by the magnesite tailings is effectively relieved, and recycling of the magnesite resources is facilitated; the electric smelting forsterite refractory brick prepared by the method has the characteristics of high strength, high density and good high-temperature resistance, and is easy tobond with a layer of kiln coating with a certain thickness, so that the service life of a kiln lining is prolonged.
本发明涉及一种水泥回转窑烧成带用电熔镁橄榄石质耐火砖，属于窑衬耐高温材料领域，粒径5‑3mm电熔镁橄榄石砂、粒径3‑1mm电熔镁橄榄石砂、粒径1‑0mm电熔镁橄榄石砂、粒径200目电熔镁橄榄石砂和烧结镁砂以及外加纸浆废液结合剂，经预混、混合、成型、干燥和烧成制备而成。本发明方法是利用电熔菱镁矿尾矿方式制备，有效缓解菱镁矿尾矿对土地资源占用，利于菱镁矿资源循环再利用；本方法制备的电熔镁橄榄石质耐火砖具高强度、高致密度、良好的耐高温性能的特点，易粘结一层具有一定厚度的窑皮而延长窑衬使用寿命。
