【摘要】 对巴西和印度粗矿粉的烧结性能进行了研究，结果表明，这两种矿烧结性能较差，当它们的总和超过综合料配比的３０％时，烧结矿产量降低，含粉率升高，大烟道温度下降。其原因是巴西矿和印度矿粒度组成差，颗粒形成不合理及软化温度区间大所致。更多还原

【Abstract】 This paper has done study on sintering character of coarse ore powder of Brazil and india. The result expresses that the sintering character of two ores is poor,when total quantity of two ores is over 30% of complex mixture ratio the productivity of sintering ore is decreased, the powder content of sintering ores is increased , and the temperature of main chimney flue is lowered. The cause produced above questions are unreasonable graininess composition of Brazil and india ore, unreasonable graininess shaping and large softening region in the process of sintering.更多还原
