摘要
通过调研多家水泥厂,选定三组率值(率1配方:KH=1.01,SM=2.62,IM=1.37;率2配方:KH=1.01,SM=2.71,IM=1.39;率3配方:KH=1.01,SM=2.71,IM=1.35)进行试验.分别掺入0.5%、1.0%、2.0%的CuO试剂,煅烧至1200℃、1250℃、1300℃、1350℃、1400℃、1450℃,利用化学分析和XRD等方法对熟料进行检测.结果表明,CuO既是矿化剂又是助溶剂;随着煅烧温度的升高,煅烧试样的f-CaO含量总体呈下降趋势;率2配方时的游离氧化钙的含量最少且较稳定;随着重金属掺量的增大,熟料主要矿物相C3S的形成温度明显降低,且在1400℃、1450℃下CuO掺烧量为1.0%和2.0%时均有液相出现.
Abstract
Through conducting research on multiple cement plants,this paper selects three sets of rate values(rate#1 formula:KH=1.01,SM=2.62,IM=1.37;rate#2 formula:KH=1.01,SM=2.71,IM=1.39;rate#3 formula:KH=1.01,SM=2.71,IM=1.35)for testing.Add 0.5%,1.0%,and 2.0%CuO reagents respectively,calcine to 1200℃,1250℃,1300℃,1350℃,1400℃,1450℃,and use chemical analysis and XRD methods to detect the clinker.The results show that CuO is both a mineralizer and a co solvent.As the calcination temperature increases,the f-CaO content of the calcined sample generally shows a decreasing trend.The content of f-CaO in rate#2 is the least and relatively stable.With the increase of heavy metal content,the formation temperature of the main mineral phase C3S in the clinker significantly decreases,and liquid phase appears when the CuO content is 1.0%and 2.0%at 1400℃and 1450℃.
