摘要
采用金相观察及扫描电镜分析的方法,对S460M热轧H型钢成品翼缘内侧的裂纹状缺陷进行了分析,结果表明:该缺陷属于异型坯缺陷,通过提高异型坯表面质量可有效消除该缺陷。
By using means of metallographic phase and scanning electron microscope,the crack defects inside the flange of S460 M hot rolled H-section steel were studied.The results showed that they were beam blank defects.These defects can be effectively eliminated by improving the surface quality of the blank.
