Steel ladle upper nozzle castable, prefabricated part and preparation method of steel ladle upper nozzle castable
The invention provides a steel ladle upper nozzle castable, a prefabricated part and a preparation method of the steel ladle upper nozzle castable. The ladle upper nozzle castable is prepared from thefollowing raw materials in parts by weight: 10-60 parts of tabular corundum, 5-50 parts of waste ceramic particles, 5-50 parts of waste air brick particles, 10-60 parts of fused magnesia-alumina spinel, 0.5-20 part of white corundum, 0.5-20 part of alpha alumina micro powder, 1-10 parts of pure calcium aluminate cement, 0.5-10 part of chromium oxide, 0.01-0.3 part of organic fibers, 0.05-2 part of a water reducing agent and 0.005-0.2 part of metal aluminum powder. The ladle upper nozzle castable is resistant to scouring and erosion and long in service life, the replacement frequency of an upper nozzle in one ladle service is reduced, and the influence on production of a steel mill can be reduced to the maximum extent on the premise that safety is guaranteed.
本发明提供一种钢包上水口浇注料、预制件及其制备方法，按照质量份数计算，钢包上水口浇注料的制备原料包括以下组分：板状刚玉10‑60份、废陶瓷颗粒5‑50份、废透气砖颗粒5‑50份、电熔镁铝尖晶石10‑60份、白刚玉0.5‑20份、α氧化铝微粉0.5‑20份、纯铝酸钙水泥1‑10份、氧化铬0.5‑10份、有机纤维0.01‑0.3份、减水剂0.05‑2份、金属铝粉0.005‑0.2份。该钢包上水口浇注料耐冲刷、抗侵蚀、寿命长，降低一个包役内上水口更换次数，能在保证安全的前提下最大限度减少对钢厂生产的影响。
