摘　　要：对钠硅渣熟料配方及烧结温度进行了试验研究,并进行探索性工业溶出试验。结果表明,钠硅渣熟料应采用高钙比（C/S=2.1-2.2）配方,熟料烧结温度宜在1 200-1 270℃;由于熟料品位低,使得溶出液固含高、溶出二次反应剧烈,溶出浆液必需进行快速分离,以获得较好的溶出效果。Calcium silica ratio（C/S）of sodium aluminosilicate clinker and sintering temperature were studied.Exploratory industrial dissolution test was conducted.The results show that sodium aluminosilicate clinker should be sintered at 1 200-1 270℃ with C/S of 2.1-2.2.The digestion solution has high solid concentrate and secondary digestion reaction is intense due to low grade of clinker.The digestion solution must be filtered quickly to obtain better digest results.
