薄板坯连铸用钢水合理精炼工艺探讨

A Discussion on Suitable Secondary Refining Technique for Thin Slab CC

常见的与薄板坯连铸工艺相配合的精炼工艺有LF、RH和CAS。通过对三种精炼工艺的适用性分析,探讨了在生产热轧卷板时,利用提高精炼操作水平等措施可以实现LF与薄板坯连铸机的合理衔接;在生产冷轧薄板时,RH与CAS是与薄板坯连铸相匹配的较为合理的炉外精炼工艺。

The common secondary refining techniques adopted with thin slab CC, include in LF, RH, and CAS. Through the applicability analysis of three secondary refining techniques, this paper discussed how to realize LF and thin slab CC appropriate syntaxial through increasing operant level and other measures when producing hot rolled plate; RH and CAS are the appropriate secondary refining techniques matched with thin slab CC when producing light cold -rolled sheet.
