| Abstract:Aiming at the uneven temperature distribution and the large temperature difference on the working surface of steel drying cylinder with oil heating during operation. The structure of the steel dryer was optimized by three-dimensional modeling and simulation. In this study, the structural improvement of the steel cylinder was mainly carried out from three aspects: changing the number of circulating oil pass-ages; changing the arrangement of the holes on the oil tank; and changing the structure of the circulating oil passage. The research results showed that the performance of the steel dryer with 20 circulating oil passages, the holes on the oil tank were arranged in a single row, and the circulating oil passages connected with each other was better than that of other dryer cylinders. It achieved the uniform distribution of working surface temperature and temperature difference in ±5℃. |
