摘要
薄板坯连铸连轧技术发展近30年,已由最初的单坯轧制模式发展到现在的无头轧制,炼钢-连铸新技术的不断应用贯穿其整个发展历程,特别是高效化生产、铸坯无缺陷技术方面的不断进步,促进了薄板坯技术的发展。简要回顾了薄板坯连铸连轧产线的发展概况,介绍了薄板坯连铸连轧产线配套炼钢-连铸关键技术的发展情况,分析了各项关键技术的特点、难点以及某些关键装备研制方面取得的进展,在此基础上,提出了薄板坯连铸连轧产线炼钢-连铸技术的发展方向。
The thin slab continuous casting and rolling technology has developed for nearly 30 years. It has developed from the original single slab rolling mode to the present endless rolling. The continuous application of new steelmakingcontinuous casting technologies runs through its entire development process,especially the continuous progress of the high-efficiency production and the slab defect-free technology,which has promoted the development of the thin slab technology. The development of the thin slab continuous casting and rolling production line was briefly reviewed,the development of key technologies of the steelmaking and continuous casting for the thin slab continuous casting and rolling production line was introduced,the characteristics and difficulties of each key technology and the progress made in the development of some key equipments were analyzed,and on this basis the development direction of the steelmaking and continuous casting technology of the thin slab continuous casting and continuous rolling production line was put forward.
