摘要
针对Q345B钢卷板开平后在制造汽车箱梁加工过程中出现的冷折弯开裂现象,对缺陷材料进行了金相、钢种化学成分和性能的对比分析,并通过优化成分含量改善其性能指标,取得了良好效果。
According to cold bending cracking occurred in ear girder manufacturing by straightened Q345B steel plate, analysis is made for the microstructure, chemical composition and performance of defect material, its performance index is improved through the optimization of component content, and achieves zood result.
