一、引言随着高炉操作的总趋势向无喷油发展,钢铁制造工业部门现在正由产量时代转向了一个在稳定操作的前提下追求低成本和高质量的新时代。这便对目前占高炉炉料80～90%的烧结矿的成本降低和质量改进提出了
I. INTRODUCTION With the general tendency of blast furnace operation to develop without fuel injection, the steel manufacturing industry is now shifting from a production era to a new era of pursuing low-cost and high-quality under the premise of stable operation. This presents the cost reduction and quality improvement of the sinter which currently occupies 80-90% of the blast furnace charge
