稀土金属加入液态钢中的行为曾有过一些研究。??报道了熔炼过程中钢中稀土元素以及当时氧、硫的变化曲线。??及??探讨并研究了稀土金属的脱氧能力。??试验了稀土对钢液粘度及流动性的影响。??测定过稀土元素引起铁水表面张力的降低。但对稀土金属加入到液态钢中从那些方面消耗掉,如何控制回收,却很少研究。国内各厂稀土金属的加入方法也有所不一,回收不够稳定。为着更有效地利用稀土资源,我们在高频感应炉中着重探讨影响稀土回收的因素,进行了稀土金属加入液态钢中行为的研究。 There have been some studies on the behavior of rare earth metals in liquid steel. Reported the melting process of rare earth elements in steel and then the oxygen and sulfur curve. And to explore and study the ability of deoxidation of rare earth metals. ?? Test the effect of rare earth on the viscosity and liquidity of molten steel. Determination of rare earth elements caused by the reduction of the surface tension of molten iron. However, rare earth metals into the liquid steel consumption from those aspects, how to control the recovery, but rarely studied. The domestic plants rare earth metals are also added to the different methods, recovery is not stable enough. In order to make more efficient use of rare earth resources, we focus on the factors that affect rare earth recovery in high frequency induction furnaces and conduct the research on the behavior of rare earth metals in liquid steel.
