ABSTRACT

It is imperative to reduce the pollution and energy consumption in the blast furnace ironmaking process. High pellets operation is a developing direction in the future. The function of blast furnace slag system cannot be ignored. In order to balance the MgO content in blast furnace slag and improve the metallurgical properties of pellets in the high pellets ratio operation, the research on MgO-bearing pellets is necessary. In this paper, the metallurgical properties of MgO-bearing pellets and the properties of blast furnace slag effect by MgO in different raw material conditions, especially for Vanadium Titanomagnetite, were analysed and summarized. This review provided a reference for the development of MgO-bearing pellets and the performance of blast furnace slag effect by MgO. It is hoped to reduce pollution and promote the technical progress of blast furnace ironmaking.

摘要

降低高炉炼铁过程的污染和能源消耗势在必行。高颗粒作业是今后的一个发展方向。高炉渣系统的作用不可忽视。为了平衡高炉渣中的MgO含量，提高高球团比作业中球团矿的冶金性能，有必要对含MgO球团矿进行研究。本文对不同原料条件下含MgO球团矿的冶金性能以及MgO对高炉渣性能的影响，特别是对钒钛磁铁矿的性能进行了分析和总结。该综述为含MgO球团矿的开发和MgO高炉渣效应的性能研究提供了参考。
