差热分析法研究稀土对水泥熟料形成过程的影响

Rare Earth of Differential Thermal Analysis Law Reasearch Is to The Influence of Cement Fired Refractory Material Formation Course

采用差热分析(DTA)和化学分析等测试手段和分析方法,通过对照分析稀土对水泥熟料形成过程平行对比试验的研究。证明,添加稀土后碳酸盐大量分析,一期固相反应、二期固相反应及硅酸三钙形成的温度分别比不加稀土时间提前约10℃、15℃、25℃和35℃;达到同一煅烧程度时添加稀土的试料在高温下停留时间可缩短5～15min,证明添加稀土对水泥熟料的形成具有显著的促进作用。

Using the methods of differential thermal and chemical analysis,by contrast,the research to cement fired refractory material formation process pair-comparsion testing of rare earth of analysis of equal rank.Proving,adds that carbonate is a large number of behind rare earth decomposes,that on phase contraryly admittedly answers and two phases is contrary admittedly should and the temperature that three calcium silicic acid forms respectively than shifting to an earlier date simple 100C,150C,250C and 350C s when not adding rare earth.Adding rare earth when achieving the same level calining tries the material shorten 5-15 min's proof next stay time at high temperature,adding the formation to the cement fired refractory material of rare earth possessing notablely promoting the effect.
