摘 要: | 为改善和控制弹簧钢中夹杂物的尺寸和形态, 以喂丝方式在工厂现场试验添加钇基重稀土处理51CrV4弹簧钢, 经现场取样后, 通过对试样进行大样电解、金相、扫描电镜和能谱等研究分析手段, 观察研究51CrV4弹簧钢铸坯和轧材中典型夹杂物。结果表明:重稀土Y对夹杂物改性明显, 在弹簧钢中添加钇基重稀土后, 显微夹杂物主要以RE2O3、RE2O2S、RE2S3等稀土夹杂物形式存在, 生成的稀土复合夹杂物尺寸在2~4 μm, 并且呈规则球状; 大型夹杂物中检测后并未发现含有稀土元素, 但是大型夹杂物的形态比未加稀土的夹杂物更为圆整和球状, 且大小更为细化.

Abstract: | With wire feeding in site test of adding Y-base heavy rare earth in 51CrV4 spring steel, to improve and control the size and morphology of inclusion, through field sampling, by large sample electrolysis, metallography, examination scanning electron microscopy and spectroscopy analysis means of observation, analyzed the typical inclusions of casting and rolling material in 51CrV4 spring steel. The practice results show that The addition of yttrium based heavy rare earth steel in spring steel has obvious effect on inclusion modification, the mainly inclusions exist in RE2O3, RE2O2S, RE2S3 and other rare earth inclusions, generation of rare earth compound inclusion size in 2~4μm, and a regular spherical shape; large inclusions in detection not found rare earth elements, but the large inclusions morphology than inclusions without rare earth is more rounded and spherical, and the size is more refined. |
