1 前言柳钢烧结厂目前使用的进口铁矿粉有澳矿和印度矿,它们各有其自身的烧结特性,对烧结矿的产量质量指标有直接影响。烧结矿冶金性能的好坏,制约着高炉冶炼经济技术指标的提高,同时也影响整个柳钢经济效益的提高。为寻求合理原料结构,公司组织了这次进口矿试验,其目的是:(1)模拟生产条件,研究进口矿的最佳配比;(2)研究碱度及FeO、MgO
1 Foreword The imported iron ore powder currently used by Liuzhou Iron and Steel Sinter Plant has both Australian and Indian mines, each of which has its own sintering characteristics and has a direct impact on the quality indicators of sinter production. Sinter metallurgical properties of good or bad, restricting the blast furnace smelting economic and technical indicators to improve, but also affect the economic benefits of the entire increase of Liuzhou Iron and Steel. In order to seek a reasonable structure of raw materials, the company organized the test of imported ore with the aim of (1) simulating the production conditions and studying the optimal ratio of imported ore; (2) studying the alkalinity and the contents of FeO and MgO
