| 摘 要： | 通过试验模拟和实机轧制试验，对传统Q345钢的静态再结晶行为、应变累积效应和晶粒细化机制等进行研究，分析了影响中厚钢板显微组织和力学性能的主要因素。结合首钢中板厂3500mm机组的特点，确定出Q345中厚钢板的TMCP生产工艺。实践表明该工艺可使钢板的平均组织晶粒度达到10～12级，带状组织降至1．5级以下。

| Abstract: | By simulation and rolling experiments in lab, the static recrystallization, strain accumulating effect and grain refining mechanism of Q345 steel were studied. And the main factors which influence the structure and properties of plate steel were analyzed. The TMCP of Q345 plate was established for 3500 mm rolling mill at Shougang plate plant. The practice showed that the average grain size of the plate produced by this process can reach ASTM No.10-12 grade, and the grade of band structure can decreased to below 1.5. |
