The results show that the sinters for the bf in shuicheng iron and steel co . , ltd . have middle rdi ( low temperature reduction degradation index ) , choice ri ( reduction index ) , wider softening temperature range , high start melt and dropping temperature , smaller melt and dropping temperature range
研究结果表明，水钢烧结矿具有中等及中等偏下的低温还原粉化性能和优良的还原性能；软化区间偏宽，开始熔化温度高和开始滴落温度高，却有较窄的熔滴区间。
Abstract : experiments indicated that under tanggang material conditions and at the basicity range of 1 . 4 1 . 7 , the sinter tumbler strength and reduction desintegration properties were worsen as australian fine ores added ; but at the basicity range of 0 . 4 0 . 6 , the sinter strength can improved with both adding of indian fine ores or australian fine ores
文摘:试验表明：在唐钢原料条件下,碱度1 . 4 1 . 7范围内,配加澳粉矿使烧结矿强度和低温还原粉化性能下降,印度粉矿影响不明显;在碱度0 . 4 0 . 6范围内,配加印度粉矿和澳粉矿都有利于烧结矿强度的提高。
