摘要
根据中国常见进口铁矿石种类,选择了8种进口铁矿石进行烧结基础性能研究,包括同化性、铁酸钙生成能力和液相流动性。探讨了烧结原料基础性能与铁矿石物理化学性能之间的关系。随着铁矿石中TFe含量的增加,A/S和Ig的降低,同化温度有增加的趋势。铁酸钙的生成能力随着Al2O3含量和A/S的增加而增多。随着SiO2含量的提高,Al2O3含量和A/S的降低,其液相流动性不断增加。
According to present status of imported iron ores in China, the basic sintering characteristics of eight kinds of imported iron ores, such as assimilation, capacity of calcium ferrite formation and liquid phase fluidity, were investigated. The relationship between the basic sintering characteristics and the physical and chemical properties of iron ores was systematically discussed. The results show tha： with the increase of the TFe content , the decrease of the ratio A/S and Ig in iron ore, the assimilation of temperature has an increasing trend. The formation ca pacity of calcium ferrite increases with increase of A12 03 content and A/S. With the increase of SiO2 content , the decrease of A12 03 content and the ratio A/S, the fluidity of liquid phase rises.
