摘　　要：对电石渣做钙质原料烧制熟料形成动力学进行研究,探索电石渣配料对熟料烧成的影响。根据金斯特林格方程和阿累尼乌斯公式计算熟料形成反应的表观活化能。研究表明:电石渣配料煅烧水泥熟料的形成反应动力学较好地满足金斯特林格方程,电石渣替代石灰石配料烧制水泥熟料是可行的。但电石渣在替代石灰石煅烧熟料时熟料形成的表观活化能升高,会引起煅烧困难,在实际操作中要控制电石渣的掺量和改变工艺参数。For searching the influence of carbide slag preparation ratio on clinker sintering,dynamic study was done for the sintering process using carbide slag as calcareous raw materials. Based on Ginstling Equation and Arrhenius Formula,the apparent activating energy for action of clinker formation can be calculated. Study shows that Ginstling Equation can be well satisfied by formation action dynamics during cement clinker sintering using carbide slag in raw meal preparation. So,it is feasible to produce cement clinker using carbide slag instead of limestone. But during the sintering process,the apparent activating energy for the action of clinker formation willbe raised consulting in sintering difficulty. In practical operation,intermingled quantity of carbide slag should be controlled and the process parameters should be changed and modified.
