1000 Celsius High Temperature Lab Continous Tunnel Furnace Oven Kiln

High-temperature tunnel furnaces provide a uniform heat treatment for materials through a continuous, stable heating environment. The heating system (electric heating elements or gas burners) generates heat, which is transferred to the material through radiation, convection, and conduction. A conveyor belt feeds the material from one end and transports it through the heating chamber and out the other end. The conveyor speed is adjustable to control the heating time.

    Material Selection

    Structure and Operating Principle

    Furnace: Constructed of high-temperature-resistant materials (such as 80mm thick insulation and SUS310S stainless steel), it features a narrow internal heating channel and is rust-resistant with a paint finish on the exterior.

    Heating System:

    Heating Elements: 0Cr27Al7M02 high-temperature resistance wire is used for temperatures below 1000°C; silicon carbide rods (resistant to 1450°C) or silicon-molybdenum rods (resistant to 1750°C) are available for higher temperatures.

    Layout: Heat is evenly distributed along the length of the furnace, transferring heat through radiation, convection, and conduction.

    Conveyor: Teflon mesh belt or SUS310S stainless steel mesh belt, resistant to high temperatures and corrosion, ensuring continuous and uniform material transport.

    Temperature Control System:

    Sensor: Thermocouple array monitors temperature in real time.

    Control Algorithm: A dynamic PID parameter fine-tuning model combines fuzzy control with a neural network to achieve a temperature control accuracy of ±1.5°C.

    Execution Layer: Temperature stability is maintained by adjusting heating element power and conveyor speed.

    1. Furnace Body Material 

    Cr-Mn-N Casting: Contains chromium, manganese, and nitrogen, offering excellent creep and oxidation resistance, suitable for temperatures up to 1000°C.

    Stainless Steel: The inner chamber is made of SUS316S#, while the outer chamber is cold-formed to ensure corrosion resistance and structural stability.

    1. Conveyor Belt

    SUS310S Stainless Steel Mesh Belt: High-temperature (1100°C) and corrosion-resistant, suitable for high-temperature environments.
