介绍了CCSB开发过程中如何充分利用薄板坯连铸连轧工艺和设备优势,通过化学成分和控轧控冷工艺的合理设计,来保证产品的性能,特别是低温韧性。同时通过对产品的组织和性能的分析及介绍,表明本钢开发的CCSB完全满足船用钢板的使用要求,并获得了中国船级社的工厂认可。
This paper introduces how to make full use of the advantages of thin slab continuous casting and rolling process and equipment in the process of CCSB development. The chemical composition and the reasonable design of controlled rolling and controlled cooling process can ensure the product performance, especially the low temperature toughness. At the same time, through the analysis and introduction of the organization and performance of the products, it shows that the CCSB developed by Benxi Iron and Steel Co., Ltd. fully meets the requirements for the use of marine steel plates and has been approved by the factory of China Classification Society.
