摘要
为阐述烧结过程熔融机制和成矿机制,明确MgO、Al2O3质量分数对烧结液相生成和矿物组成的影响是至关重要的。利用Factsage软件计算Fe2O3-SiO2-CaO-Al2O3-MgO体系的液相生成,计算氧分压在500Pa时,不同温度,不同MgO、Al2O3质量分数下体系液相生成和液相区分布的影响。通过烧结试验,分析烧结矿的矿相和矿物成分,结合软件计算得出烧结矿中MgO质量分数为2.0%、Al2O3质量分数为3.0%时其液相量、矿相、矿物成分达到最优适合烧结冶炼的标准。
To illustrate the melting mechanism and mineralization mechanism of sintering process.Making clear the influence of MgO and Al2 O3 content on sintering liquid phase formation and mineral composition is of vital impor-tance.Liquid phase formation of Fe2 O3-SiO2-CaO-Al2 O3-MgO system is calculated by Factsage software.As well as the effect of variation MgO and Al2 O3 content on liquid phase formation and distribution under different tempera-tures at oxygen partial pressure of 500 Pa.Through the sintering experiment,mineral phase and mineral composition of sinter ore are analyzed.The optimal sintering smelting standard for mass fraction of liquid phase,miner phase and mineral composition is concluded with the software calculation when the content of MgO and Al2 O3 is 2.0% and 3.0% in sinter respectively.
