降低焦粉消耗技术是近年来日本新日铁住金公司专门针对配用含高结晶水劣质铁矿开发出一项新技术。采用该技术,能在烧结机利用系数和烧结矿质量保持不变的情况下,有效降低焦粉消耗,并大幅度减少CO2排放。当前,各大钢厂为了降低烧结配矿成本,都在更多地使用含高结晶水的豆矿和马拉曼巴矿等劣质铁矿,这势必会增加焦粉消耗(因结晶水分解需耗热)。为了降低燃耗,日本新日铁住金公司开发出在烧结原料中配入部分预还原铁料及高效
In recent years, Japan’s Nippon Steel and Sumitomo Metal Industries Co., Ltd. has developed a new technology specifically for the use of low-grade iron ore containing high crystalline water. This technology can effectively reduce the coke consumption and substantially reduce the CO2 emission while the sintering machine utilization coefficient and the sinter quality remain unchanged. At present, in order to reduce the cost of sintering and ore blending, the major steel mills are making more use of low-grade iron ore such as beans with high crystal water and Maramamba ore, which will inevitably increase coke consumption Heat). In order to reduce fuel consumption, Japan’s Nippon Steel and Sumitomo Chemical Co., Ltd. developed in the sintering of raw materials with part of the pre-reduction of iron and efficient
