摘　　要：为研究干法含碳致密水泥生料块烧成条件下的碳燃烬度,制成不同厚度的含碳致密水泥生料块(CCP料块)在电炉模拟的工业立窑生产环境中进行烧成实验,即经1000℃还原气氛预烧0.5h和1400℃或1450℃氧化气氛中烧成半小时至1h,可制得游离钙足够低的熟料,其内含碳获得良好的燃烬度。一项数值计算程序(CCPIM)为实验结果提供了基于碳燃烧扩散速率控制机理的数值解答,吻合良好。To study the burnout ratio of dry proeess eompaet earbon raw meal in eement firing eondition, different thickness of eompaet carbon raw meal samples were prepared, and the clinker of low enough free CaO and good carbon burnout ration was produced in simulation condition of real industrial vertical kiln production environment prefired for half of an hour in reducing atmosphere at 1 000 ℃or for 0.5-1 hour in oxidizing atmosphere at 400℃ and 1450℃. A calculating programme gives the numerical value solution based on diffusing rate eontrol meehanism of earbon burning for the experiment and they inoseulated well.
