超低头连铸板坯的夹杂物

Investigation of Non-metallic Inclusions for the Slab of Super Low Head Continuous Caster

摘要: 采用硫印法,X光透射法、大样电解法和金相法,对钢包、中间包和连铸坯中的夹杂物进行了系统调查研究。对浇注过程中夹杂物类型、数量、组成和分布以及二次氧化进行了讨论。所得结果,对改进生产操作和提高铸坯纯净度具有指导意义。

Abstract: The non-metallic inclusions during the casting process in ladle,tundish, mould and slab of super low head caster has been investigated using supher. print, X-ray, slime method and microscope. The quanlity, morphology composition and dimensional distribution of inclusions in slab as well as reoxy-dation, slag composition change etc are discussed.
