1000 Celsius High-Temperature Tunnel Furnace Oven from China Suppliers - Continuous Lab Kiln Factory Solutions

High-temperature tunnel furnaces are essential for achieving uniform heat treatment of materials in China. As a leading supplier in the industry, our factory produces advanced furnaces that create a stable and continuous heating environment. These systems utilize either electric heating elements or gas burners to generate heat, which is effectively transferred to the materials through radiation, convection, and conduction. A conveyor belt systematically moves the materials through the heating chamber, with adjustable speeds allowing precise control over heating time. Trust our China-based factory for reliable and efficient heat treatment solutions.

    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 (FAQ)

    What materials are used in the furnace construction?

    The furnace is built with high-temperature-resistant materials including 80mm thick insulation and SUS310S stainless steel, completed with a narrow internal heating channel and a rust-resistant painted exterior.

    Which heating elements are used for different temperature levels?

    0Cr27Al7M02 high-temperature resistance wire is applied for temperatures below 1000°C. For higher operating temperatures, silicon carbide rods (up to 1450°C) or silicon-molybdenum rods (up to 1750°C) are used.

    How is heat distributed and transferred across the furnace?

    Heat is evenly distributed along the entire length of the furnace through a combination of radiation, convection, and conduction mechanisms.

    What options are available for the conveyor belt?

    A Teflon mesh belt or SUS310S stainless steel mesh belt is used, providing high temperature and corrosion resistance for continuous and uniform transport.

    What is the temperature control accuracy of the system?

    The system achieves a precise temperature control accuracy of ±1.5°C by utilizing a dynamic PID fine-tuning model combined with fuzzy control and neural network algorithms.

    How does the execution layer maintain stable temperatures?

    Thermal stability is maintained through dynamic real-time adjustments of heating element power and conveyor speed.
