采用微型烧结设备研究了烧结温度、碱度和MgO含量对高褐铁矿配比混合矿黏结相强度的影响，结果表明：随着烧结温度、碱度、MgO含量的增加，黏结相强度先升高后降低，当烧结温度为1280℃、碱度为1.6、MgO质量分数为2.0%时，高褐铁矿配比混合矿的黏结相强度最高。生产中应适当降低褐铁矿的配比，保证混合铁矿粉具有足够的黏结相强度。
The binding phase strength of mixed iron ore with high limonite ratio was determined by micro-sintering appa-ratus at different sintering temperature, basicity and MgO content. The results reveal that, binding phase strength of mixed iron ore increased at first and then decreased as sintering temperature, basicity and MgO content increased. It reached the highest value when the sintering temperature was 1 280℃, alkalinity was 1.6 and mass percent of MgO was 2.0%. Limo-nite ratio should be reduced appropriately in production, so that the mixed iron ore has adequate binding phase strength.
