摘要
对Q345BH型钢腹板力学性能异常的试样进行了分析，并对翼缘和腹板力学性能进行了比较，确定翼缘腹板轧制压下量和翼缘腹板冷却速度不同是性能差异存在的主要原因。
Based on an analysis of the abnormal mechanical property of Q345B H-beam web samples and the comparison of mechanical properties between the. flange and the web, it is confirmed that the main causes of the property difference for Q345B H-beam are draught and different cooling rates after rolling of flange and web.
