摘要

摘要: 運用Factsage軟件模擬了MgO含量對CaO-SiO₂-Al₂O₃-MgO熔渣中液相區的影響.結果表明，隨著CaO-SiO₂-Al₂O₃-MgO渣中MgO含量增加，渣中低熔點液相區整體向低CaO高SiO₂區移動.相圖中1500℃液相區比例由0%MgO（質量分數）時的25.05%上升至9%MgO（質量分數）時的52.69%，而后降至15%MgO時的46.70%.相圖中1400℃液相區比例由3%MgO時的14.41%上升至11%MgO時的34.39%，而后降至15%MgO時的31.04%.相圖中1300℃液相區比例由5%MgO時的5.57%上升至14%MgO時的11.02%，而后降至15%MgO時的10.50%.相圖中1200℃液相區域比例在MgO為0~6%時為零，由7%MgO時的0.88%上升至11%MgO時的1.22%，在MgO為13%~15%時降為零.模擬結果可對以CaO-SiO₂-Al₂O₃-MgO為基本組元配置煉鋼渣系的成分選擇提供有效指導.

Abstract: The influence of MgO content on liquid phase in CaO-SiO₂-Al₂O₃-MgO slag system was simulated by Factsage software.The results show that,with increase of MgO content in CaO-SiO₂-Al₂O₃-MgO slag,the low melting point liquid area moves forward ‘low CaO high SiO₂’ area. 1500℃ liquid area ratio of phase diagram rises from 25.05% of 0% MgO(mass fraction) to 52.69% of 9% MgO,and drops to 46.70% of 15% MgO. 1400℃ liquid area ratio of phase diagram rises from 14.41% of 3% MgO to 34.39%of 11% MgO,and drops to 31.04% of 15% MgO. 1300℃ liquid area ratio of phase diagram rises from 5.57% of 5% MgO to 11.02% of 14% MgO,and drops to 10.05% of 15% MgO. 1200℃ liquid area ratio of phase diagram is 0 when MgO content during 0 to 6%,and rises from 0.88% of 7% MgO to 1.22% of 11% MgO,then changes to 0 when MgO content during 13% to 15%.Simulation results provide an effective guidance for composition selection of steelmaking slag with the CaO-SiO₂-Al₂O₃-MgO components as the basic configuration.
