摘　　要：研究了唐钢薄板坯连铸连轧线(FTSR)生产的4种不同厚度SS40 0钢板的显微组织和力学性能,并测定了钢板的应变硬化指数。实验结果表明:随钢板厚度的减小,其晶粒尺寸呈现出减小的趋势,该钢板具有较为优良的综合力学性能及较好的成形性。另外,通过对5 .75mm厚SS40 0钢板的系列温度冲击实验发现,该钢板在-60℃时仍具有较好的韧性。The microstructure and properties of SS400 carbon strips with four different thickness produced by Tangshan flexible thin slab rolling technology (FTSR) were researched, the strain hardening exponent was also determined. The results of the experiments show that the grain size of the carbon strips reduces with the decreasing of the thickness;the general mechanical properties and formability of the carbon strips are preferable;the flexibility of 5.75mm SS400 strip at -60℃ is still good by the serial temperature impact test
