摘要
检查北满特钢生产的35MnBM钢发现凹陷和裂纹。采用金相观察、扫描电镜观察和能谱分析等方法对35MnBM钢裂纹形成的原因进行了分析。提出措施:严格控制夹杂物含量、尺寸和分布,控制表面凹陷脱方现象,以消除裂纹形成的内在、外在原因。
The gap and crack have been checked in 35MnBM steel produced by Bei Man Special Steel Company. Through analyzing the reasons for 35MnBM steel cracks by metallographic observation, scanning electron microscope observation and energy spectrum analysis, the measures have been brought forward to eliminate the inside and outside reasons for cracks, such as inclusion content, size and distributing control, and surface dishing offsquare control.
