Box type resistance furnace is a common heating equipment widely used in laboratories, industrial production, and scientific research fields. It utilizes the principle of resistance heating to convert electrical energy into thermal energy, thereby heating and melting materials. It is used in high-temperature heat treatment equipment with a sealed furnace chamber, suitable for heating treatment of various metal and non-metal materials.

The structure of box type resistance furnace

1.The structure of a box type resistance furnace:

① Furnace cavity structure: Box type resistance furnaces are usually composed of a sturdy metal shell with a furnace cavity inside. The size and shape of the furnace cavity can be customized according to the requirements of heating the workpiece.
② Resistance wire: A resistance wire or electric heating element is installed in the furnace chamber, which heats up the resistance wire and generates high temperature through electrification. Resistance wires are usually made of high resistance alloys to ensure stability at high temperatures.
③ Control system: The box type resistance furnace is equipped with an advanced temperature control system, which can accurately control the temperature inside the furnace chamber. These systems typically include temperature sensors, controllers, and heating elements.
④ Insulation material: Aluminum oxide fiber insulation material is used on the inner wall of the furnace chamber to reduce energy loss and ensure uniform temperature distribution inside the furnace chamber.
