查询词典 main bearing

The cuspidine is all long known as the main factor leading to the low strength o the sinter bearing fluorine, But with the fluorine decreasing by a wide margin, the strength of the sinter bearingfluorine get lower. So, the first work is to fine out the reason to cause the strength low.

含氟烧结矿中的枪晶石一直被认为是制约包钢烧结矿强度的主要因素，但随着含氟量的大幅度降低，烧结矿的强度却进一步恶化，因此，弄清影响低氟烧结矿强度的原因是提高烧结矿强度的前提和基础。

This thesis has systematically studies the microstructure of the sinter bearing fluorine of different compositions and in different sintering condition.(1) The main units of the Low Fluorine Sinter are magnetite、hematite、 SFCA、larnite、glass and pore. The cuspidine doesn't form for the low content fluorine, and the fluorine is in glass; Sinter basicity dominates the forming of the larnite and SFCA, when basicity is between 1. 72 and 1. 96, there are more larnites in the binder phase, and when the basicity is biger than 1. 96, there are more SFCA in the binder phase; the hematite appears like magnetite and usually is around pore.

为此，本文对不同组成、不同烧结条件的烧结矿样品进行了系统的显微分析和研究，其主要内容包括：(1)构成低氟烧结矿的主要组元有磁铁矿、赤铁矿、铁酸钙、硅酸二钙、玻璃体和气孔，由于含氟量的降低，枪晶石等含氟矿物并未形成，氟分布在后期凝固的玻璃体中，其中硅酸二钙和铁酸钙受碱度影响较大，硅酸二钙在碱度为1.72～1.96范围内形成较多，铁酸钙在碱度大于1.96含量增多，赤铁矿呈磁铁矿假象，多分布在气孔周围，各组元的生成顺序为：磁铁矿—硅酸二钙—铁酸钙—玻璃体。
