<正> 本工作的目的是调查研究弧形和水平连铸机生产的铸坯中大型氧化物夹杂的行为,提供铸坯改善纯净度的依据。 弧形连铸机浇注123×123mm方坯,从盛钢桶经中间包至结晶器为敞开浇注。由铸坯的头、
The coarse oxide inclusions isolated from either horizontal or curved continuous casting strands were examined on their content,shape,composition and size distribution bv means of the slime method and elecrtoprobe. They are oxides of SiO_2-Al_2O_3-MnO system. About 80% or more of them are coarser than 80um. The inclusion content in the horizontal continu-ous casting strand is far more than in curved one owing to preventing the secondary oxida-tion by clo e connection between the tundish and mold. Thus, the protective casting is avail-able to improve the steel purity.
