铁矿粉添加石灰石熔剂,生产自熔性或熔剂性烧结矿的设想,早在1912年就被提出来了。但一直到五十年代才开始在工业上大规模使用。生产实践证明,高炉操作指标的改善与自熔性烧结矿生产的技术进步,紧密相关。在高炉中大量使用自熔性烧结矿,不仅可以在冶炼过程中少加或不加石灰石熔 The idea of ​​adding limestone flux to iron ore powder to produce self-fluxing or fluxing sinter was proposed as early as 1912. But it was not until the 1950s that large-scale industrial use began. Production practice has proved that the improvement of blast furnace operating indicators is closely related to the technological progress of self-fluxing sinter production. In the blast furnace mass use of self-fluxing sinter, not only in the smelting process with little or no limestone melt
