对薄板坯连铸连轧技术的分析

与传统连铸相比,薄板坯连铸在铸坯厚度、浇铸速度、铸态组织、在线连轧等方面都发生了很大变化,既具有冷却强度大、生产线短、能耗低等优点,也具有表面质量不高、产品适应范围较小等缺点.近年来我国薄板坯连铸连轧技术发展较快,已建成十几条生产线,但对其生产情况褒贬不一.通过对薄板坯连铸产品组织、化合物析出、产品的适应性等方面的优缺点进行分析比较,客观地评价了薄板坯连铸连轧生产技术.

Objective Analyzing of Thin Slab Continuous Casting and Rolling Technology

There are distinct differences in slab thickness,casting speed,cast structure and on-line continu- ous rolling between thin slab casting and conventional process.The thin slab process has some advantages of stronger cooling strength,shorter product line and lower consuming.In the meantime,it also has some disad- vantages of not so good surface quality and small range adaptability in production.In recent years,the technol- ogy of thin slab continuous casting and rolling has been developed very much in China ...
