99 castable for prolonging service life of launder in low-oxygen copper rod production and preparation method of 99 castable
The invention discloses a 99 castable for prolonging the service life of a launder in low-oxygen copper rod production. The 99 castable comprises the following raw materials in percentage by weight: 7-15% of electric smelting white corundum powder, 5-11% of alpha-Al2O3 superfine powder, 5-11% of electric smelting spinel fine powder, 1-4% of an auxiliary agent, 6-15% of a binding agent, 0.1-0.4% of a water reducing agent and the balance of sintered tabular corundum particles, the preparation method of the 99 castable comprises the following steps: S1, prefabrication; S2, primary mixing; and S3, mixed material preparation. According to the castable prepared by the invention, raw material particles can be in close contact by strictly controlling the raw material types, particle sizes, heat treatment systems and other procedures in each step, and meanwhile, the structural characteristics of different materials and the particle gradation advantages of the raw materials with different particle sizes are utilized; the prepared castable has the advantages of high normal-temperature compression strength, high thermal shock resistance and the like.
本发明公开了用于低氧铜杆生产中延长流槽寿命的99浇注料，99浇注料的原料按重量百分比计包括：7～15％的电熔白刚玉粉，5～11％的α‑Al2O3超微粉，5～11％的电熔尖晶石细粉，1～4％的辅助剂，6～15％结合剂，0.1～0.4％的减水剂，余量为烧结板状刚玉颗粒；99浇注料的制备方法为：S1、预制，S2、初次混合，S3、混料制备；本发明制备浇注料，通过严格的控制各步骤原料种类、粒度及热处理制度等工序，使得原料颗粒之间能够紧密接触，同时利用了不同材料的结构特征和不同粒度的原料之间的颗粒级配优点，使得所制备的浇注料具有常温耐压强度大、抗热震性高等优点。
