Abstract: The temperature distribution of inner cover was studied by using a simulating software of FLUENT to simulate the hearth model , the single inner cover model and the temperature optimization model of an annular furnace, then an improvement scheme of temperature uniformity was proposed and tested by experiment. The results showed that the temperature difference and magnetic uniformity between top and bottom of the steel coil were successfully optimized by superimposing a heat insulation material on the side of the coil base, which can provide supports for the improvement in magnetic properties of oriented silicon steel.

Key words: oriented silicon steel, hightemperatureannealing furnace, simulation, annular furnace, temperature uniformity
