摘　　要：分析了回转窑石油焦煅烧质量不稳定的原因，找出了影响因素并采取了有效措施，真密度由≥2．02g／cm。（约80％）提高到≥2．04g／cm2（约50％），比电阻由520～560i．d-1·m降低至低于500—520μΩ·m，窑尾温度由940～1020~降低到820～870℃，沉降室温度由1120～1160℃降低到820～830℃，对沉降室及大窑内衬寿命起到积极作用。After unstable reasons of the quality of petroleum coke in rotary kilns are analyzed, influence factors are found and improvement measures are taken, the real density is increased from 92.02g/cm3 （ about 80% ） to 92.04g/cm3 （ about 50% ）, the specific resistance is decreased from 520 - 560μΩm to 500 -520μΩm, the temperature of the end of rotary kiln is decreased from 940 - 1020℃ to 820- 870℃ and the temperature of combustion chamber is decreased from 1120 - 1160℃ to 820 - 8300℃, which can be of benefit to the serve life of kiln lining.
