| 摘 要： | 通过对国内某钢厂DH36高强度船板钢轧制成型之后的成品板材进行研究,利用数学模拟的分析方法,建立了DH36高强度船板钢主要化学成分与基本力学性能之间关系的数学模型,并在此基础上重点分析了各元素随Mn含量的变化对力学性能产生的影响。结果表明：在相关成分允许的波动范围内,Mn元素对冲击功的影响主要呈斜率为负的直线关系,对屈服强度、抗拉强度、断面收缩率的影响也均呈直线关系,但斜率规律与其他元素的含量有关,需具体分析。

| Abstract: | Plate products of DH36 high-strength ship plate steel, roll formed by a steelworks in China, were investigated. Analy-zing by mathematical simulation method, a mathematical model was built for the connection between main chemical components and basic mechanical properties of DH36 high-strength ship plate steel. Based on the model, the impact of composition fluctuation of man-ganese on various mechanical properties was emphatically analyzed. The results show that the influence of manganese on impact energy mainly appears as the negative linear relationship. The impact of manganese on the yield strength, tensile strength and reduction of ar-ea also appears as the linear relationship, and the slope is impacted by other elements and needs further investigation. |
