在毛主席革命路线指引下,富源矿厂连年完成和超额完成国家下达的产品计划,但炼铁焦比却高达1.036吨。厂生矿入炉的精料工作较长期以来做得较好,但在高炉吃熟料上一直未解决,烧结矿质量长期没有过关。攻克烧结矿质量关成为解决矿源不足和进一步实现降焦增铁的关键。我们组织攻关组,从3吨小烧结堆试验逐步扩大到35吨大烧结窑,成功生产出含铁52％、碱度1.1～1.2、氧化亚铁在 Guided by Chairman Mao’s revolutionary line, Fuyuan Mine completed and oversubscribed the product plans laid down by the state in successive years but the ironmaking coke ratio was as high as 1.036 tons. Raw material into the furnace of raw materials into the work done better for a long time, but in the blast furnace to eat clinker has not been solved, sinter quality has not been cleared for a long time. To overcome the quality of sintered ore has become the key to solve the problem of insufficient mineral resources and further reduce the iron loss. We organized research groups, from 3 tons of small sintering reactor test gradually expanded to 35 tons of large sintering kiln, the successful production of 52% iron, alkalinity 1.1 ~ 1.2, ferrous oxide in
