低温还原分化性是一种化学反应现象。指铁矿石在低温还原过程中发生碎裂粉化的特性。在竖炉直接还原工艺中，低温还原粉化性能是决定球团能否适应竖炉反应器以及还原气体组成的关键因素之一，球团粉化越严重，炉子的透气性就越差。
试验结果表明：配加硼灰泥粉后，烧结矿成品率提高，冷强度和低温还原粉化性能改善。
As a result, with introducing this kind of additive, the sinter yield elevated, cold strength and RDI of sinter improved.
以国内某钢铁公司的炼铁原料为基础，进行了高炉喷吹煤与废塑料条件下的矿石低温还原粉化性能研究。
Based on the material of iron in some iron and steel companies, the low temperature reduction degradation of iron ore in the condition of injecting blends of coal and waste plastic in BF is studied.
