III. Overall Technical Description
The furnace is mainly divided into four parts: the furnace body, atmosphere control system, temperature control system, transmission system, and auxiliary systems.

3.1 Furnace Body Design
The structural division of the furnace body is detailed in Figure 1 and Table 1.

3.3 Temperature Control System Design
3.3.1 Temperature Measurement: Each control and monitoring point uses an independent K-type thermocouple.
3.3.2 Control Instruments: High-precision intelligent regulators with PID auto-tuning, high-temperature alarm, thermocouple failure indication, and other alarm protection functions.
3.3.3 Heating Control: Heating is powered by multiple AC contactors in groups to reduce instantaneous current impact on the power grid.
3.3.4 Control Method: Solid-state relay zero-crossing triggering.
3.3.5 Overtemperature Handling: When overtemperature occurs in any zone, the system triggers audible and visual alarms and cuts off heating.

3.4 Transmission System Design
3.4.1 Transmission Control: Inverter-driven variable frequency motor with speed control via a reducer, allowing continuous speed adjustment.
3.4.2 Mesh Belt Conveyor: Driven by sprockets and chains, with main and passive wheels. Friction between the drive wheel and mesh belt ensures operation. Belt alignment devices are installed at the inlet and outlet.

IV. Auxiliary Systems
4.1 Industrial Control Computer Integrated Control System
4.1.1 DCS control system with lower-level intelligent instrument control and upper-level industrial computer monitoring.
4.1.2 Hierarchical login with a user-friendly Chinese interface.
4.1.3 Multiple program storage for easy editing and calling.
4.1.4 Real-time temperature and alarm status display. Data storage and printout capabilities.
4.1.5 Furnace temperature calibration function for better process fitting.
4.1.6 Timed heating control for energy and time savings.
4.1.7 Communication interface for MES system integration to read equipment operation data and status.

4.2 Ultrasonic Cleaning System (for Mesh Belt)
Effectively cleans impurities and contaminants from mesh belt gaps, preventing workpiece contamination.
