| 摘 要： | 在MoSi2炉和MgO坩埚内用复合脱氧剂对430不锈钢液进行了脱氧实验研究.以Al和FeSi作为对比脱氧剂,考察了SiCaBa、SiCaBaAl、SiCaBaMg、SiCaBaAlSr四种复合脱氧剂对430不锈钢中的全氧含量及脱氧产物的分布、尺寸和形貌的影响.实验表明,用SiCaBa对430不锈钢液脱氧,可获得较低的氧含量,其脱氧产物易于上浮,钢中的夹杂物尺寸明显减小且形态发生改善呈球形.

| Abstract: | Molten 430 stainless steel deoxidized by complex deoxidizers was studied in a MoSi2 furnace and an MgO crucible. The SiCaBa,SiAlBaCa,SiCaBaAl,SiCaBaMg and SiCaBaAlSr alloys were used as the deoxidizers,and Al and FeSi were used as the deoxidizers for contrasting. The total oxygen content in steel,the distribution,size and morphology of deoxidation products were studied. The results show that when deoxidized by SiCaBa alloy,a lower total oxygen content of 430 stainless steel can be obtained,the deoxidation p... |
