What is force convection system of glass tempering furnace?

Glass tempering furnace is a high-temperature heating equipment, and its convection principle is to heat up materials through the convection of air inside the furnace. The following is a detailed explanation of the convection principle in the glass tempering furnace:

1. Heating element inside the furnace: Glass tempering furnaces usually use electric heating elements, such as electric heating wires or electric heating tubes, which generate high-temperature heat energy.

2. Convective heat transfer of air inside the furnace: The heating element transfers heat energy to the air inside the furnace, causing its temperature to rise. The heated hot air will generate thermal convection, which is a circulating flow formed between the rising hot air and the falling cold air.

3. Hot air rise: The density of hot air is lower, so it will be relatively light and rise to the top of the furnace.

4. Cold air descent: The density of cold air is higher, so it will be relatively heavy and descend to the bottom of the furnace.

5. Convective heat transfer effect: The temperature difference between the hot air at the top of the furnace and the cold air at the bottom of the furnace can cause convective heat transfer of the air. When the hot air rises, it will take away the heat on the surface of the material and evenly distribute the heat throughout the entire furnace chamber.

6. Thermal equilibrium: Through convective heat transfer of air inside the furnace, the temperature inside the furnace gradually reaches an equilibrium state. This can ensure that the material is uniformly heated throughout the entire furnace cavity.

For LEVER glass tempering furnace, it has following technical Features:

1. This system mainly used to process Low-e glass, specially for soft (off-line) Low-e glass.
