Microporous light-weight castable for steel ladle permanent lining and preparation method of microporous light-weight castable
The invention relates to a lightweight microporous castable for a permanent lining of a steel ladle and a preparation method thereof, the lightweight microporous castable for the permanent lining of the steel ladle comprises the following components: 35-50% of flint clay, 35-45% of alumina hollow spheres, 10-15% of high bauxite powder, 3-6% of pure aluminate cement and 0.1-0.5% of a dispersant, totaling 100%. Wherein the aluminum oxide hollow spheres are low in heat conductivity, are excellent light heat insulation refractory materials, can provide good heat insulation performance for the light microporous castable serving as a permanent lining for a steel ladle, reduce heat loss of molten steel in the steel ladle, and avoid the phenomenon that the molten steel is prone to falling off due to fast heat loss. The phenomena of serious slag adhesion, nodulation, cold steel formation and the like of the ladle wall caused by temperature drop are avoided, and meanwhile, the existence of the heat insulation plate and the nano plate is replaced, so that the damage to a working layer refractory caused by thermal deformation of the heat insulation plate is avoided, the use safety of the steel ladle is also improved, and the effects of energy conservation, emission reduction and safety guarantee are also achieved for steelmaking enterprises.
一种钢包永久衬用轻质微孔浇注料及其制备方法，所述的一种钢包永久衬用微孔轻质浇注料的组分为：焦宝石35‑50％，氧化铝空心球35‑45％，高铝矾土粉10‑15％，纯铝酸盐水泥3‑6％，分散剂0.1‑0.5％，以上各组分之和为100％，其中氧化铝空心球的热导率都较低，是一种优异的轻质隔热耐火材料，能够为轻质微孔浇注料作为钢包用永久衬提供较好的保温性能，减少了钢水在钢包中的热量散失，避免出现了因热量流失快，温度下降导致的包壁严重挂渣、结瘤、结冷钢等现象的产生，同时因为替代了绝热板和纳米板的存在，避免了因为绝热板受热变形对工作层耐材造成的伤害，也提高了钢包使用的安全性，对炼钢企业来说也起到了节能减排，保障安全的作用。
