中文摘要:根据绝热温度的热力学计算原理,采用TurboC2程序编制出CuO/Al体系绝热温度的数值计算程序。对体系绝热温度进行了数值计算并进行了验证,同时也对添加不同稀释剂Cu粉对绝热温度的影响进行了研究。结果表明,体系预热温度较低时,绝热温度为产物Cu的沸点温度(2843 K),标况下约有52.9%的产物Cu为气相,预热温度仅仅提高了产物Cu的蒸发量。
英文摘要:Based on the principle of thermo-dynamic theory, a mathematic calculation program for adiabatic temperature prediction of CuO/Al system was established by TurboC2 course, the adiabatic temperature of aluminothermic system was also calculated and verified. The effect of Cu diluting agent on the adiabatic temperature was also discussed. The results show that the adiabatic temperature comes to be the boiling point of production Cu (2843 K) at low preheating temperature of reactant(<1953 K). About 52.9% gas phase Cu is produced at standard condition,preheating reactant only increases the gasification rate of Cu.
