摘　　要：对碱金属在各种烧结含铁物料中的赋存状态及在烧结过程行为机理进行了研究。试验结果表明:包钢烧结矿中K2O、Na2O主要源于自产铁精矿、高炉返矿、瓦斯灰和熔剂;烧结过程的K2O、Na2O脱除较少,多数以硅酸盐形式富集在烧结矿的玻璃质中。In the paper,it is studied the occurrence of alkali metals in the various iron - containing materials of sinte- ring and their behavior mechanisms in sintering. The test results show thatK2O and Na2O in sinter are mainly from the self -produced iron concentrate, blast furnace return fines, gas ash and flux. Less K2O and Na2O in sintering are removed be- cause most of them are enriched in the glassiness of sinter as the form of silicate.
