A numerical model, which considers the anisotropic heat conduction inside the 3D coil core and convection and radiation heat transfers inside the furnace, is built
In the batch annealing process, 3-4 cylindrical steel coils (typically 10-20 t each) are stacked on a furnace base and annealed under a hydrogen atmos-phere. The air-gaps
In the steel industry, annealing furnaces are used to con- trol the material and surface properties of steel strips by means of heat treatment. Continuously increasing demands
A heat transfer-based model was developed to predict temperature variation within cold rolled coil during batch annealing furnace operation. The model was
This study examines two important parameters: the convective heat-transfer coefficient and radiative heat-transfer coefficient, which have a significant impact on coil
During the coil annealing operation, heat transfer from the furnace to the coil surfaces is by radiation and convection mechanisms, whereas to the inner core of
During the coil annealing operation, heat transfer from the furnace to the coil surfaces is by radiation and convection mechanisms, whereas to the inner core of the coil is
Through the above analysis, we can see clear that improvements in the annealing furnace coil placed way, first of all, effectively alleviate the same coil heating temperature
In this paper we approach hydrogen flow characteristics in the furnace and through a set of coils using an annealing non-differential model. Fluid flow is schematized as a pipe
