摘要
对方大特钢1 050 m^3高炉投产以来的炼铁技术进步进行总结。通过采取"开中心、兼顾边缘"的煤气流分布控制,实行大矿角、大矿批、长风口、高块矿比例、快速复风、小矿回收等一系列措施,两座高炉炉况保持了长期稳定顺行,并实现了在高冶炼强度、高利用系数下的技术指标进步,目前燃料比稳定在500 kg/t左右。
The technological progress of iron making are summarized for 1 050 m^3 BF in Fangda Special Steel. Gas flow distribution of ＂ open center,taking into account the edge＂ is controlled,a series of technological breakthroughs like： the large ore angle,large batch of ore,high lump ore ratio,fast complex wind,small ore recovery are implemented. Two blast furnaces are maintained long-term stable and smooth operation,the improvement of the technical index of high smelting intensity and high utilization coefficient are realized. The current fuel ratio is kept stable around 500kg/t.
