Kiln mouth rapid repairing material and preparation method thereof
The invention discloses a rapid kiln mouth repairing material and a preparation method thereof. During preparation of the kilneye rapid repairing material, the raw materials used in parts by mass are as follows: 50-55 parts of special grade bauxite clinker particles, 5-10 parts of brown aluminum oxide particles, 3.5-10 parts of alpha-aluminum oxide micro powder, 10-15 parts of silicon carbide micro powder, 2-3 parts of a high-purity polymer binder, 2-3 parts of a coagulant and 2-3 parts of an inorganic cementing agent. The method for preparing the kiln mouth rapid repairing material from the raw materials specifically comprises the following steps: a, adding the prepared special-grade bauxite clinker particles and brown aluminum oxide particles into a wet mill, and mixing the special-grade bauxite clinker particles and the brown aluminum oxide particles; b, adding an inorganic cementing agent into the uniformly mixed mixture in the step a, mixing and grinding for 3-5 minutes, adding a binding agent, a coagulation accelerator, alpha-aluminum oxide micro powder and silicon carbide powder, mixing and grinding, and discharging the primary material; and c, ageing the materials for 20-24 hours after the materials are discharged from the mill for the first time, and discharging the final materials after the materials are mixed and milled for the second time. The problems that an existing kilneye repairing material is poor in thermal shock resistance and volume stability, and ignition operation cannot be conducted in time after construction repairing is completed are solved.
本发明公开了一种窑口快速修补料及其制备方法，所述窑口快速修补料制备时用到各原料的质量份数如下：特级铝矾土熟料颗粒50‑55份、棕刚玉颗粒5‑10份、α‑氧化铝微粉3.5‑10份、碳化硅微粉10‑15份、高纯高分子结合剂2‑3份、促凝剂2‑3份、无机胶结剂2‑3份；用上述原料制作窑口快速修补料的方法具体包括如下步骤：a、将准备好的特级铝矾土熟料颗粒、棕刚玉颗粒加入湿碾机中进行混合；b、向步骤a中混合均匀的混合料中加入无机胶结剂，混碾3‑5分钟，再加入结合剂、促凝剂、α‑氧化铝微粉和碳化硅粉混碾后初料出碾；c、在第一次出碾后困料20‑24小时，再二次混碾后终料出碾。解决现有窑口修补料抗热震性差、体积稳定性差、施工修补完成后无法及时点火运行的问题。
