China High-Temperature Tunnel Furnace Oven Kiln - Continuous 1000 Celsius Heating, Reliable Suppliers & Factory

High-temperature tunnel furnaces are essential for providing uniform heat treatment for materials in various industrial applications. As a leading factory in China, we specialize in manufacturing advanced heating systems that utilize electric heating elements or gas burners to generate consistent heat. This heat is efficiently transferred to materials through methods such as radiation, convection, and conduction, ensuring optimal processing conditions. Our tunnel furnaces feature an adjustable conveyor belt that transports materials smoothly from one end to the other, allowing precise control of the heating time. Partner with trusted suppliers in China to enhance your production capabilities with our high-quality tunnel furnaces

    Technical Parameters

    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.

    Frequently Asked Questions

    What materials are used in the construction of the furnace?
    The furnace is constructed using high-temperature-resistant materials, specifically featuring an 80mm thick insulation layer and SUS310S stainless steel. The exterior is finished with a rust-resistant paint.
    What heating elements are available for different temperature ranges?
    For temperatures below 1000°C, 0Cr27Al7M02 high-temperature resistance wire is used. For higher temperature requirements, silicon carbide rods (resistant up to 1450°C) or silicon-molybdenum rods (resistant up to 1750°C) are utilized.
    How is heat distributed within the furnace?
    Heat is distributed evenly along the entire length of the furnace, transferring thermal energy through a combination of radiation, convection, and conduction.
    What types of conveyor belts are used for material transport?
    The system utilizes either a Teflon mesh belt or a SUS310S stainless steel mesh belt. Both options are highly resistant to high temperatures and corrosion, ensuring continuous and uniform transport.
    What is the temperature control accuracy of the system?
    The system achieves a temperature control accuracy of ±1.5°C. This is managed by a dynamic PID parameter fine-tuning model that combines fuzzy control with a neural network.
    How does the execution layer maintain temperature stability?
    Temperature stability is actively maintained by the execution layer through real-time adjustments to the heating element power and the conveyor speed.
