Charpy impact value

In order to predict the Charpy impact energy of Q345B hot rolled plate at Jinan steel,an ANN(Artificial Neural Network) impact energy model was developed considering the factors of composition,process parameters and strength of the plate.

为了对济钢Q345B中厚板的常温夏比冲击吸收功进行预报并指导生产,采用神经元网络建立了冲击吸收功与化学成分、工艺参数、屈服强度及抗拉强度等因素间的关系预报模型。

It analyzes problems that may occur in the process of Charpy impact test of pipeline steel combining with steel pipe specification through sampling,sample machining,testing equipment and testing process,and proposes a few suggestions upon testing temperature control and operating process.

结合管线钢管标准规范,分别从取样、试样加工、试验设备及试验过程等方面分析了管线钢管夏比冲击试验中可能出现的问题,并针对试验温度控制和操作过程提出了几点建议。
