How does a rotary tube furnace work?

Time：2024-07-08

　　
The working principle of the rotary tube furnace mainly includes the following aspects:

The rotary tube furnace consists of heating elements, furnace tubes, rotating devices, temperature control systems and other parts.

The heating elements usually use resistance wires, silicon carbon rods, etc., which generate heat when powered on. This heat is transferred to the furnace tubes by radiation, convection and other means.

The furnace tube is the place where the material is placed for heating treatment. The rotating device enables the furnace tube to rotate at a constant speed or variable speed during the heating process.

When the furnace tube rotates, the material inside is constantly turned and mixed. This action allows the material to receive heat more evenly, avoiding local overheating or uneven heating that may be caused by fixed placement.

The temperature control system is responsible for monitoring and adjusting the temperature in the furnace. The temperature in the furnace is sensed by thermocouples or other temperature sensors, and the signal is fed back to the controller. The controller adjusts the power output of the heating element according to the set temperature value to maintain the stability and precise control of the temperature in the furnace.

During the entire working process, the rotary tube furnace provides uniform, stable and controllable environmental conditions for material heating, reaction, and processing through rotating furnace tubes and precise temperature control to meet various process requirements.
