锌铝池中Si含量对渣相形成的影响
Effect of Si content in the zinc-aluminium bath on the formation of slag phase
摘要
Abstract
The solubility of silicon in a Zn-50%Al- xFe- ySi ( in atomic fraction) molten bath and the content of silicon in a Zn-30%Al-2%Fe-xSi ( in mass fraction) molten bath corresponding to the appearing of τ5 slag phase and the disappearing of FeAl3 phase were calculated at different temperatures using the Thermo-Calc software. At the same time, the solubility of silicon in liquid phase in the Zn-50%Al-xFe-ySi alloy and the phase equilibrium relationship of the Zn-30%Al-2%Fe-xSi alloy were experimentally determined by using the equilibrium alloy method. The results show that the calculated solubility of silicon in liquid phase in the Zn-50%Al-xFe-ySi system at 540, 560, 580, 600 and 620℃ are 0. 82%, 0. 95%, 1. 11%, 1. 28% and 1. 47%, respectively, which agree well with the experimental data. When the temperature of the molten bath is 580, 600, and 620℃, the calculated content of silicon in the Zn-30%Al-2%Fe- xSi alloy corresponding to the appearing of τ5 phase in the molten bath is 0. 6%, 0. 72% and 0. 84%, and the values corresponding to the disappearing of FeAl3 phase are 1. 12%, 1. 22% and 1. 34%, respectively, which agree basically with the experimental results.关键词
