II. Main Technical Parameters

1. Operating temperature range: Room temperature (RT) to 650°C, which is the standard working temperature interval.

2. Maximum test temperature: Up to 700°C, but it is generally recommended not to exceed 650°C to ensure long-term stable operation of the equipment.

3. Furnace dimensions (internal): 800 × 800 × 800 mm (width × height × depth).

4. Number of temperature zones: 1 temperature zone, providing a uniform single-zone heating space.

5. Temperature control points: 1 control point for precise temperature regulation.

6. Heating method: Utilizes stainless steel heaters as heating elements, featuring high-temperature resistance, oxidation resistance, and long service life.

7. Maximum heating power: Does not exceed 36 kW.

8. Furnace temperature uniformity: Under 650°C conditions, after 1 hour of empty furnace stabilization, temperature uniformity is ±5°C.

9. Insulation material: Full fiber material with excellent thermal insulation, minimizing heat loss.

10. Air supply method: A centrifugal fan circulates hot air to enhance temperature uniformity inside the furnace.

11. Temperature control system: Centered around a Yamatake temperature controller, combined with Siemens PLC, ensuring stable system operation suitable for prolonged continuous use.

12. Upper computer system: Equipped with an MCGS configuration touchscreen, featuring a user-friendly interface, intuitive operation, and support for real-time data monitoring and parameter settings.

III. Gas and Cooling System

1. Inlet Gas (Nitrogen) Requirements:

• Gas Type: High-purity nitrogen (N₂)

• Nitrogen Purity: ≥ 99.999% (i.e., 5N grade)

• Inlet Pressure: 0.2 ~ 0.4 MPa

• Nitrogen Consumption: Approximately 10 m³/h

1. Cooling Method: The equipment adopts natural furnace cooling without active forced cooling (e.g., water or air cooling). After high-temperature operation, natural cooling is required, and cooling time must be reasonably planned.

2. Water Inlet Requirements (if equipped with water-cooled components):

• Water Quality: Clean and non-corrosive

• Water Temperature: ≤ 23°C

• Water Pressure: 0.2 ~ 0.4 MPa

• Water Flow Rate: Approximately 2 ~ 6 L/min

(Note: Not all equipment is equipped with a water-cooling system; confirm based on the actual model.)

1. Ventilation System: Requires non-contact connection to the user's exhaust system, with an exhaust capacity greater than 15 m³/h, used to discharge furnace exhaust or protective gases.

IV. Power Supply and Electrical Conditions

1. Power Supply: Three-phase five-wire system, voltage 220/380 V, frequency 50 Hz.

2. Power Capacity: The required power capacity for equipment operation should exceed 50 kVA.

3. Power Cable Color Coding (Three-Phase Five-Wire Standard):

• Live Wires (L1/L2/L3): Yellow, green, red

• Neutral Wire (N): Blue

• Ground Wire (PE): Yellow-green

1. Power Requirements: Must use industrial-grade stable power with minimal voltage fluctuations. It is recommended to install voltage stabilizers or overcurrent protection devices to avoid power outages or voltage instability affecting equipment operation and process quality.

V. Installation Environment and Site Requirements

1. Ambient Temperature: 0 ~ 40°C. Temperatures outside this range may affect equipment performance and control accuracy.

2. Relative Humidity: Less than 80% RH, with no condensation, to avoid moisture affecting electrical components.

3. Ambient Gas: No corrosive gases, flammable/explosive substances, or strong acid/alkali vapors.

4. Airflow Environment: No strong air currents or vibration interference; maintain a stable environment.

5. Floor Requirements: Must be level, sturdy, and free of significant vibrations, with a load-bearing capacity exceeding 300 kg/m².

6. Recommended Installation Dimensions: 2000 mm (width) × 3000 mm (depth) × 3000 mm (height).

7. Minimum Installation Area: Greater than 6 m² to ensure sufficient space for operation and maintenance around the equipment.

8. Ventilation and Exhaust: The site must have good exhaust conditions and connect to the user's exhaust system to ensure timely discharge of furnace gases and maintain a safe operating environment.

VI. Control System Features

1. Upper Computer: Uses an MCGS touchscreen with configuration-based software, featuring an intuitive interface for easy operation. Supports temperature monitoring, parameter setting, status display, and alarm functions.

2. Lower Computer: Composed of Yamatake C1A and C1M temperature controllers and Siemens PLC for precise temperature control and system logic, enhancing automation and safety.

3. Data Acquisition and Control: The system collects temperature data in real time and responds quickly to control commands, ensuring stable and consistent temperature control for long-term uninterrupted operation.

4. System Stability: The overall control system is optimized for reliable, low-failure operation, suitable for industrial continuous production environments.
