对褐铁矿的烧结基础性能进行了研究,研究结果表明:褐铁矿1 200℃即开始同化,同化时间只有3 min,比磁铁矿和赤铁矿的同化温度低、同化时间短。褐铁矿的液相流动性也高于其它赤铁矿,达100%,液相固结强度和连晶强度也比赤铁矿低很多,所以褐铁矿的烧结矿强度低。但褐铁矿的同化性好,生成铁酸钙的能力比其它矿石高20%,所以褐铁矿的还原性好。 The basic properties of limonite sinter were studied. The results showed that limonite began to assimilate at 1 200 ℃ and the assimilation time was only 3 min, which was lower than that of magnetite and hematite. The assimilation time was short. The fluidity of limonite is also higher than that of other hematite, reaching 100%. The liquid-phase consolidation strength and crystallinity are also much lower than those of hematite, so the strength of limonite sinter is low. However, the limonite has good assimilation and the ability to produce calcium ferrite is 20% higher than other ores, so the limonite has good reducibility.
