用烧结和造球——焙烧的方法,将铁矿粉或选洗铁精矿造块用于高炉炼铁,已普遍用于工业生产。在不焙烧的条件下将铁矿粉在低温下固结的方法之一——碳酸化固结的造块方法,国内外早已有所研究。研究表明:此种球团有较好的机械强度,还原性良好,抗水性强。我国在小高炉炼铁中已有采用。但由于尚缺少用于大型高炉的报导,有关冶炼性能及在冶炼 Sintering and pelletizing - roasting method, iron ore powder or iron washing iron ore block making blast furnace ironmaking, has been widely used in industrial production. One of the methods for consolidating iron ore powder at low temperature without calcining, carbonation and consolidation, has long been studied at home and abroad. Studies have shown that: This pellet has good mechanical strength, good reducibility, strong water resistance. China has been used in small blast furnace ironmaking. However, due to the lack of coverage for large blast furnaces, the smelting performance and smelting
