摘　　要：根据CaO-SiO2-Al2O3三元相图研制开发了一种碱性中间包覆盖剂,研究了其与酸性和中性覆盖剂吸附Al2O3夹杂的能力,指出碱性覆盖剂具有优于酸性和中性覆盖剂吸附Al2O3夹杂的能力,并通过工业试验验证了所研制的碱性覆盖剂具有优良的冶金效果。A kind of basic tundish covering flux was developed according to the phase diagram of CaO - SiO2 - Al2O3. The absorbing ability for Al2O3 inclusion of the basic tundish covering flux was compared with the acid and neutral tundish covering flux, it was founded that the basic tundish covering flux was of better absorbing ability for Al2O3 inclusion. The industrial tests also approved that the basic tundish covering flux was of good metallurgical characters.

关 键 词：中间包覆盖剂 Al2O3夹杂吸附 表面张力
