Abstract
The main objective in the present research is to reduce temperature difference of the steel pipes in furnace and arranging pertinently a bundle of the inside steel pipes. Moreover, transient numerical simulation was conducted by using ANSYS FLUENT commercial software to study temperature distribution of steel pipes inside the original and new designed annealing furnaces. The new model was designed by adopting the elbow inlet for generating the swirl flow. The temperature difference of steel pipes for the original furnace was 55.4 °C. However, the temperature differences of a bundle of steel pipes for the new model by using downward inlet angle of 30° was 13 °C. Moreover, temperature difference by modified model had more uniform than those of by Prieler et al. of 50 °C. Effect of Reynolds number, the horizontal and the vertical steel spacing on the temperature difference among the steel pipes was also examined. The transient simulation were performed to investigate steel pipe temperature during annealing process. In short, the results revealed that a new designed inlet configuration with this kind of geometry of an annealing furnace could be applied to minimize the temperature difference among steel pipes in steel annealing process.
