Analyses and Control of Scale on Ferrite rolled Ti-IF Steel Sheets
-
摘要: 结合某热轧厂半连轧热连轧生产线的Ti-IF钢铁素体轧制工艺, 重点阐述了Ti-IF钢铁素体区轧制工艺表面氧化铁皮的控制情况, 通过SEM扫描电镜和XRD试验分析了铁素体轧制工艺下氧化铁皮的构成、结构以及带钢宽度方向上氧化铁皮的差异性, 明确了铁素体轧制工艺下表面质量控制的优越性, 尤其是在控制氧化烧损、减少氧化铁皮生成方面效果更突出。此工艺对提高轧线成材率具有较大优势, 同时为冷轧工序减少氧化铁皮缺陷发生提供保障, 为后续酸洗试验研究奠定了基础。Abstract: In this paper the surface scale formation of ferrite rolling to Ti-IF steel on hot semi-continuous rolling line had been discussed.Through the SEM and XRD experiment analysis the composition and microstructure of the scale along the steel strip width direction under processes of ferrite rolling had been determined.It is found out the ferrite rolling process is benefit for surface quality control.
