    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

    • 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

    Q: What materials are used to construct the furnace?

    The furnace is built with high-temperature-resistant materials, including 80mm thick insulation and SUS310S stainless steel. It features a narrow internal heating channel and a rust-resistant paint finish on the exterior.

    Q: Which heating elements are used for different temperature ranges?

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

    Q: How is heat distributed inside the furnace?

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

    Q: What types of conveyor belts are available?

    The system offers either a Teflon mesh belt or a SUS310S stainless steel mesh belt. Both options are highly resistant to high temperatures and corrosion to ensure continuous, uniform material transport.

    Q: What is the temperature control accuracy of the system?

    The system achieves a temperature control accuracy of ±1.5°C using a dynamic PID parameter fine-tuning model that combines fuzzy control with a neural network.

    Q: How does the system maintain temperature stability?

    Temperature stability is maintained at the execution layer by dynamically adjusting the power of the heating elements and the speed of the conveyor belt based on real-time data from the thermocouple array.
