FAILURE ANALYSIS OF TUBE BODY CORROSION IN NEW CEMENT DRY KILN
新型水泥干法窑筒体失效分析

The rust layers of the tube body in a new cement dry kiln were analysed by means of chemical analysis, SEM, XRD and so on. The results showed that the tube body was corroded by the harmful elements of soad, chlorine, sulphur etc., which penetrated through brick and fire loam onto the tube body. The corrosion was the result of sulphur attack and was catalyzed by colorine salt.
