低品质铁矿石经济性综合评价

介绍了低品质铁矿石的传统评价方法及其存在的问题,提出一种低品质铁矿石经济性评价新方法,即采用低品质矿石配到以传统料为骨架的中和料中,计算烧成后的烧结矿冶金价值,并结合高炉炉料结构评价其经济性和预测铁水成分。计算结果表明,该评价方法更能实际反映铁矿石冶炼的经济性,并用计算实例分析了消化某高磷铁矿对降低铁水成本的贡献。

Comprehensive Evaluation of Low Grade Iron Ore’s Economic Value

This article introduced the traditional evaluating methods of low grade iron ores and their problems. It put forward a new method of evaluation, namely, mixing low grade iron ore into traditional framework of sinter blending materials, calculating the metallurgic value of the sinter, then according to burden structure in blast furnace, evaluating the economic value of iron ore and forecasting the hot metal’s composition. The calculation result showed that the new method of comprehensive evaluation can more faithfully reflect the iron ore’s economic value. It also analyzed contribution of using high-phosphorus iron ore to reduce the cost of hot metal through the calculation of an example.
