薄板坯连铸连轧技术的新发展

DEVELOPMENT OF THIN SLAB CONTINUOUS CASTING AND ROLLING

分析了半无头轧制、超薄规格热带生产、铁素体加工、薄板坯连铸连轧品种开发等各种新技术的特点、优势、技术难点。同时对于不同设备的配置优缺点和使用的范围进行了简要的探讨 ,薄板坯连铸连轧技术可以划分为两大类 ,适合超薄规格的生产线和适合多品种生产线 ,通过这些分析力图对国内企业在新生产线建设方面提供一些帮助。

The recent development of thin slab continuous casting and rolling is introduced.An analysis is given for different relevant technologies, for example,semi endless rolling,thin gauge strip rolling,ferrite rolling and new variety development.It shows the influence of thickness of thin slab on strip properties,some advantages and problems of ferrite rolling and thin gauge strip rolling. It is suggested that thin slab continuous and rolling technologies can be divided in two branches,one is for thin gauge strip,another is for multiple steel grades and qualities.The analysis is useful for steel producers in decision making.
