| 摘 要： | ＨＹＤＬ－８５炉底用捣打料的主要晶相为方镁石，基质胶结相为低熔点过渡型的Ｃ２Ｆ（４ＡＦ）相。在实际应用中Ｃ２Ｆ具有活化晶格加速烧结的作用，且Ｃ２Ｆ分解成氧化铁及ＣａＯ，分别溶入入镁石形成ＲＯ相及反应生成高熔点Ｃ２Ｓ相，有较强的抗蚀性。

| Abstract: | The major crystal phase in bottom ramming material i s the periclase and the matrix cementation phase is the low-melting-point transient phase C2_F(C_4AF). In actual application, the C_2F plays the role of th e acti vating crystal lattice to accelerate sintering, and the C_2F which become in iron oxide and dissolved CaO are merged into periclase respectively to form Ro pha se and reacted to produce high melting point C_2S phase, which has stronger ant i-corrosion. |
