When preparing the fluxed magnesium hematite pellets with the fuels, the intensity of roasted pellets was greatly improved with the coke ratio of less than 1.5% and pellet alkalinity at 0.9.

制备内配燃料熔剂性含镁赤铁矿球团时，将焦粉配比控制1.5%以内，球团碱度控制在0.9，可显著提高焙烧球团强度。

Thus, the preparation of fluxed magnesium hematite pellet with fuel is an effective way to improve the intensity of hematite pellets.

由此可见，制备内配燃料熔剂性含镁球团是改善赤铁矿球团强度的有效途径。
