| 摘 要： | 本文用扫描电镜分析了钛质量分数为0.065%的高强度低合金钢在钙处理后铸坯和板材中夹杂物的形貌和大小;用EDS探针分析了夹杂物的成分.结果表明钛质量分数为0.065%的高强度低合金钢的夹杂物绝大部分为CaO-Al2O3-TiOx-CaS系夹杂物,并有少量的TiN,统计表明钢液钙处理效果良好.最后通过热力学计算分析了钢中TiN、CaS夹杂物的析出规律.

| Abstract: | The morphology and sizes of inclusions after liquid steel Ca treatment,in the slab and in the plate were researched by SEM for high strength and low alloy (HSLA) steel containing 0.065%Ti. The composition of inclusions was studied by EDS. The results show that most of inclusions in the slab and plate are CaO-Al2O3-TiOx-CaS inclusions,and few of them are TiN inclusions. The inclusions have been modified well by Ca treatment. The precipitations of TiN and CaS have been analyzed by thermodynamic calculation. |
