还原膨胀率是评价球团冶金性能重要指标之一。随着高炉大型化对球团矿的要求日益提高，获得较低还原膨胀率的优质球团矿是冶金工作者追求之一。本文以鞍钢现场的原料条件下，向铁精矿中添加含CaO和/或MgO等熔剂并探索其对原膨胀率影响。结果表明：CaO恶化球团的还原膨胀性能，MgO能够很好降低球团的膨胀率，并随着熔剂配比的增加而降低。

The reduction swelling of iron ore pellet is one of an important evaluation of the metallurgical properties . Because of the large-scale blast furnace, the request on pellets are constantly increasing , To get lower reduction swelling and quality of pellets is one of the pursuit of metallurgy workers. In this paper, under the present raw materials conditions of AnSteel, Adding additives containing CaO and / or MgO flux to the iron ore, and stduy on effect additives on Reduction Swelling of Iron Ore Pellets. From the results obtained, CaO deteriorated the reduction swelling of iron ore pellet, the swelling of iron ore pellet is controlled by adding additives containing MgO,With the flux in content increasing , the reduction swelling of iron ore pellet is lower.
