Numerical Simulation the Temperature Field of the Multi-Coil Batch during Annealing Process in Bell-Type Furnace
In this paper temperature field of multi-coil during batch annealing process in strong forced convective hydrogen atmosphere of Bell-type furnace was simulated, and the influences of heat transferring between steel coil and air flow under a given condition on the temperature field of the steel coil were studied. And then, the temperature field of a single and three coils steel plate were calculated during reheating, holding and cooling process according to the measured annealing curves. The simulated results show that the same trend of temperature in different steel coils. However, considering the heat radiation of steel coil, temperature variation in the topside of coil is higher than that in the bottom of coil.
