高效镁质添加剂是由高活性氧化镁粉和一种植物蛋白胶体构成。本文针对该高效镁质添加剂完全取代膨润土作为球团粘结剂进行了造球、预热、焙烧、抗压强度及成品球团的冶金性能实验研究。结果表明：配加高效镁质添加剂可以降低球团还原膨胀率1.54～4.34个百分点，初始软熔温度提高25℃，滴落温度提高250℃以上，其使用比例为3%。
：High-efficiency additive containing MgO flux is consist of active MgO and one glue of vegetal glair . In this paper, the experiment of pelletizing、pre-heating、indurating 、compression strength and the metallurgical property of pellet with high-efficiency additive containing MgO flux instead of bentonite has been determined, From the results obtained, high-efficiency additive containing MgO flux can reduce the reduction swelling of iron ore pellet, improving it’s high-temperature softening property, it is feasible that high-efficiency additive containing MgO flux to the iron ore pellet by technological view, the appropriate proportion is 3%.
