| 摘 要： | 研究了磁铁矿烧结过程初期液相的形成及加入Ｂ２Ｏ３ 对铁酸钙生成的影响。在磁铁矿烧结过程中，初期液相形成于ＦｅＯｎ－ＣａＯ－ＳｉＯ２系；ＣａＯ溶解于ＦｅＯｎ－ＣａＯ－ＳｉＯ２ 系初期液相，饱和时析出２ＣａＯ·ＳｉＯ２（Ｃ２Ｓ）。在冷却带，由液相中进一步析出Ｃ２Ｓ，同时析出铁酸钙。加入含硼物质可增加铁酸钙的生成量，减少硅酸钙的生成量。

| Abstract: | The formation of primary liquid and effect of B 2O 3 addition on the formation of calcium ferrite in magnetite sintering process have been investigated.The primary liquid is formed in the system FeO n CaO SiO 2,while CaO is dissolved in primary liquid of the system FeO n CaO SiO 2 and then saturated liquid precipitates C 2S in magnetite sintering process.The liquid further precipitates C 2S and calcium ferrite on cooling.The amount of precipitated calcium ferrite increases and that of C 2S reduces when adding boron containing materials. |
