| Summary: | Abstract The temperature uniformity of grain-oriented silicon steel coils during high-temperature annealing in bell-type furnaces critically influences the post-annealing product performance. In this study, experimental measurements of temperature values at representative points within the steel coil were combined with simulations to systematically investigate the temperature field distribution under different heating rates. The results indicate that the current heating scheme leads to a significant temperature difference between the inner ring and the peripheral area of the steel coil. To reduce this temperature difference, targeted optimization schemes have been developed to minimize the temperature differential between the coldest and hottest areas without compromising production efficiency. These optimizations aim to achieve a more uniform temperature distribution, thereby enhancing the overall performance of the final product. |
