摘　　要：通化钢铁集团有限公司FTSR薄板坯连铸连轧生产线采用硼微合金化低碳软钢技术,严格控制钢水化学成分、成品氮含量、优化连铸和轧制工艺等,成功开发硼微合金化钢TG270,并替代低碳冷轧基料SPHC板卷,产品质量和力学性能均达到用户要求。By taking technologies of boron micro-alloy low-carbon softening steel, strictly control the chemical compositins and nitrogen content in the liquid steel and optimization of the continuous casting and rolling processes in the thin slab casting and rolling production line（FTSR） in Tonghua Iron and Steel Co. ,Ltd. , the steel grade of TG270 has been successfully developed as the substitution of SPHC used for raw material of cold rolling. Both quality and mechanical properties of the products reach the requirements of customers.
