摘要

摘要: 通過對國內某鋼廠DH36高強度船板鋼軋制成型之后的成品板材進行研究,利用數學模擬的分析方法,建立了DH36高強度船板鋼主要化學成分與基本力學性能之間關系的數學模型,并在此基礎上重點分析了各元素隨Mn含量的變化對力學性能產生的影響.結果表明:在相關成分允許的波動范圍內,Mn元素對沖擊功的影響主要呈斜率為負的直線關系,對屈服強度、抗拉強度、斷面收縮率的影響也均呈直線關系,但斜率規律與其他元素的含量有關,需具體分析.

Abstract: Plate products of DH36 high-strength ship plate steel,roll formed by a steelworks in China,were investigated. Analyzing 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 manganese 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 area also appears as the linear relationship,and the slope is impacted by other elements and needs further investigation.
