摘要
通过对国内某钢厂实际生产的DH36船板钢工业大数据进行挖掘,借助Matlab数学软件建立不同元素含量下P含量与DH36船板钢各机械性能之间的数学模型。研究发现DH36船板钢的冲击功、屈服强度、抗拉强度随着P含量的升高呈先增后减的趋势,断面收缩率呈先减后增的趋势。控制P含量在0.02%附近时,抗拉强度、屈服强度、抗拉强度达到极大值,断面收缩率在此区间内虽呈下降趋势,但变化范围很小。
Based on the industrial big data of DH36 shipboard steel in a domestic steel plant, the mathematical model of DH36 shipboard steel is established by Matlab software, and the effect of P content fluctuation on the mechanical properties of DH36 ship plate steel is investigated. It is found that the impact work, yield strength and tensile strength of DH36 ship plate steel increase first and then decrease with the increase of P content, while the shrinkage rate of DH36 steel plate decreases first and then increases. When the content of P is about 0.02%, the tensile strength, yield strength and tensile strength reach the maximum value, and the shrinkage of the section shows a downward trend, but the range is very small.
