摘　　要：钢中非金属夹杂物对钢的力学性能和工艺性能的影响,主要是降低材料的塑性、韧性和疲劳性能,尤其当夹杂物以不利的形状及分布特征存在时,对材料机械性能的影响更为严重。以往氧化夹杂物分量测定采用化学法和原子吸收法,测定周期长,且Ca、Cr、Mn、Fe等元素的氧化物含量很低,化学法测定有一定局限性。而采用等离子体光谱分析(ICP-AES)定量测定氧化夹杂物,由于夹杂物含量低,相对干扰少,此法具有速度快,灵敏度高,并可同时测定多元素等特点,从而大大缩短了分析周期,降低了分析成本和劳动强度。The effect of non-metal inclusions in steels on mechanical property and shop characteristics of steels is studied.The inclusions would reduce steel’s plasticity,toughness and weary performance.Especially when the inclusions exist in disadvantageous shapes and the distribution characteristics of inclusions are not favorable,the effect on the material’s mechanical property would be serious.In the past the chemical processing and atomic absorption were taken to determine the composition of oxide inclusions,but...
