| 摘 要： | 研究和对比了经1 880 mm热轧机组在奥氏体区(945～848℃)和铁素体区(803～755℃)热精轧,卷取温度700℃以及73%压下率冷轧的3.0 mm超低碳带钢(%:0.008C、0.029Als、0.000 8B、0.001 4N)退火后的组织和性能。结果表明,与奥氏体区轧制比较,热轧采用铁素体区轧制的710℃退火后冷轧带钢具有较高的伸长率、塑性应变比(r值)和应变硬化指数(n),因而具有较好的深冲性能。

| Abstract: | Structure and properties of 3. 0 inm extra-low carbon steel strip ( % : 0. 008C, 0. 029Als, 0. 000 8 B, 0. 001 4N) hot finish-rolled by 1 880 mm hot rolling mill train in austenite region (945 ~ 848 °C ) and in ferrite region (803 - 755 °C ) , coiled at 700 °C , then cold rolled with 73% reduction and annealed have been studied and compared. Results showed that as compared with austenite region rolling, with ferrite region rolling the cold rolled steel strip annealed at 710 °C had higher elongation, plastic Strain ratio (r) and strain-hardening exponent (n) , therefore it had better deep drawability. |
