| 摘 要： | 根据热力学计算,结合生产过程实际,研究了Si脱氧条件下304奥氏体不锈钢在LF精炼、连铸过程夹杂物的变化规律.结果表明,钢水中主要形成CaO-Al2O3-SiO2类复合夹杂物,钢水中Al含量随Si含量的降低逐渐减小.当精炼渣碱度R=1.5时,随精炼、连铸过程的进行,复合夹杂物中Al2O3含量逐渐减少,CaO,SiO2含量逐渐增加.终点铸坯夹杂物成分为30%～35%CaO,20%～27%Al2O3,25%～30%SiO2,其他成分含量较少.终点铸坯夹杂物略显碱性,变形能力稍弱.

| Abstract: | Combining the thermodynamic calculation with industrial production,the variation of inclusions in 304 austenitic stainless steel deoxidized by silicon alloy during LF refining and continuous casting process was investigated.The results showed that the inclusions formed in molten steel are mainly CaO-Al2O3-SiO2 compounds,and the Al content decrease gradually with Si reduction.In the process of LF refining and continuous casting process when the refining slag basicity was controlled at 1.5,the Al2O3 content i... |
