How to improve the heat exchange effect of doboz típusú elektromos kemence?

1. Improve the sealing of the furnace door, or heat the electric heating element inside the furnace door, or add a shielding plate in the furnace door hole to reduce the radiation loss at the furnace mouth;

2. Arrange the workpieces reasonably. For the fired parts with stricter requirements, the distance between the workpieces is half the diameter (or width) of the workpieces, which has better heat transfer effect and productivity;

3. The furnace wall is coated with far-infrared paint to increase the emissivity, but most paints cannot maintain their high emissivity for a long time, which affects the use effect;

4. The corrugated dome structure in the furnace is adopted to improve the radiation heat transfer surface;

5. Improve the layout of electric heating elements and adopt plate-shaped electric heating elements to increase the radiation area of the elements and reduce the shielding of the radiation by the wire bricks. Installing electric heating elements on the top of the box-type electric furnace also has the effect of improving heat exchange;

6. Refractory fiber furnace lining is used to reduce the heat storage and heat dissipation of the furnace wall.
