【摘要】 本文研究了用CSP技术生产低碳超薄热带钢时组织演变及其影响因素。在现场取得了六道次轧卡件,并对每个轧卡件不同部位的组织进行了研究。同时,利用有限元技术模拟了连轧过程。将实验与模拟结果相合,分析了塑性应变、温度、剪切应变和析出对组织演变和晶粒细化的作用。结果对开发生产高强度热带钢有参考价值。更多还原

【Abstract】 This paper investigated the evolution of microstructures and influence factors of ultra-thin hot strips of low carbon steel produced by CSP techniques. The steel blocking samples of CSP six-passes were obtained, and microstructures at the different positions of workpiece for each pass were studied. At the same time, an explicit finite element technique was used to reveal the continuous rolling process. By combining experiment results with simulation analysis, the effects of plastic strain, temperature, shear strain and precipitation on evolution and refinement of crystal gains have been investigated. The results are useful for the development of high strength hot strips.更多还原
