含钛不锈钢连铸板坯夹杂物的行为

Inclusion Behavior of Ti-stable Stainless Steel for Continuous Casting Slab

摘要: 通过对连铸过程的系统取样,研究了含钛不锈钢中N₂、O₂、Al的变化,以及钢包、中间包、结晶器和铸坯中夹杂物类型、数量、尺寸和分布。并讨论了铸坯中夹杂物的来源和防止对策。

Abstract: The content change of N₂, O₂, Al in the Ti-stable stainless steel during the continuous casting process and the type, shape, composition and size distribution of inclusions were examined by means of taking samples from the ladle, tundish, mould and slab. The inclusions soure of c.c. slab and improving measures were discussed.
