Preparation method of hot repair gunning mix for large coke oven
The invention relates to the technical field of gunning mix production, in particular to a preparation method of a hot repair gunning mix for a large coke oven, which prolongs the service life of the gunning mix, improves the use efficiency of a converter, can save materials and reduce the cost for users, effectively prolongs the overall service life, and has the advantages of high strength, easiness in construction, simple preparation process and low cost. The industrial production is easy; the method comprises the following specific steps: S1, fine grinding and screening of raw materials: crushing and fine grinding of fused magnesite; s2, burdening: weighing the raw materials with corresponding weight components according to the weight; s3, mixing: dividing the fused magnesite into two different diameters and particle sizes according to the step S1, mixing according to the ratio of 2: 1, sequentially adding the fused pure calcium aluminate cement, the graphite, a half part of the mixture of the aluminum powder and the silicon powder, the alumina homogenized material, the aluminum sulfate, the zirconium dioxide and the plasticizer, and mixing; and S4, adding the rest half part of the mixture of the aluminum powder and the silicon powder before discharging, mixing for 7 minutes, and discharging.
本发明涉及喷补料生产的技术领域，特别是涉及一种大型焦炉用热修喷补料的制备方法，其增加了喷补料的使用寿命，提高了转炉的使用效率，能为用户节省材料和降低成本，有效延长了整体使用寿命，强度高易于施工，制备工艺简单，易于工业化生产；具体步骤如下：S1、原料细磨、筛分：电熔镁砂破碎精磨；S2、配料：按照重量称取相应重量组分原料；S3、混炼：按照步骤S1所述将电熔镁砂分为两种不同直径粒度按照2：1混合，依次加入电熔纯铝酸钙水泥、石墨、二分之一份的铝粉、硅粉的混合物、矾土均化料、硫酸铝、二氧化锆、助塑剂混炼；S4、出料前添加剩余二分之一份的铝粉、硅粉的混合物混炼7分钟出料即可。
