摘要
针对目前高铝钢用结晶器保护渣中SiO2易被钢液中的Al还原而导致连铸无法顺行的问题,设计了低SiO2试验渣系并进行粘-温曲线及熔点测试试验。结果表明:低SiO2渣系具有良好的基本理化性质,具有工业应用的潜能;通过热力学分析及钢-渣界面反应试验证明,当保护渣中SiO2含量低于6%时为非反应性保护渣。
The SiO2 component of the traditional mold fluxes can easily been deoxidized by the Al contained in liquid high aluminium steel.So a series of mold fluxes containing lower SiO2 was designed to solve this problem,and their viscosity-temperature curves and melting points were tested.The results showed that these viscosities and melting points are suitable to industrial application.The thermodynamic analysis and the steel-slag interfacial reaction experiment showed that the mold fluxes of which SiO2 content is less than 6% can be called non-reactive mold powder.
