不同位置烧结矿矿物组成及显微结构的研究与分析

STUDY AND ANALYSIS OF MINERAL COMPOSITION AND MICROSTRUCTURE OF SINTER AT DIFFERENT POSITIONS

在完成安钢常用铁矿石物化分析以及矿石高温基础性能分析的同时模拟了烧结过程,重点对烧结杯不同位置烧结横截面上烧结矿的矿相进行了研究。结果表明,上中下三层烧结矿的矿物组成与微观结构有一定的差别,上层烧结矿属于正常烧结矿,表层较脆;中层烧结矿各矿物的结晶还不够完善,矿物种类也较复杂;下层烧结矿多是未熔矿石。

The sintering process is simulated at the same time as the physical and chemical analysis of the iron ore commonly used in Anyang Steel and the performance analysis of the high temperature foundation of the ore,the ore phase of sinter on different sintering cross section of sintering cup is studied in detail.The results show that hat the mineral composition and microstructure of the upper,middle and lower sinters are different to some extent.The upper sinter belongs to the normal sinter,the surface layer is brittle,the crystallization of each mineral in the middle sinter is not perfect,and the mineral types are more complex.
