Product Parameters

I. Basic Equipment Information

• Equipment Name: Hot Air Car Furnace

• Model: HRF1350-06

II. Technical Specifications and Basic Configuration

1. Temperature Performance

   • Rated temperature: 600°C, with a maximum working temperature of 650°C, meeting the requirements of most medium-to-high-temperature heat treatment processes.

   • During a 1-hour isothermal test at 600°C (empty furnace), the temperature uniformity within the furnace was ±5°C, indicating excellent temperature distribution consistency, which helps improve product quality.

   • The maximum heating rate is 5°C/min. Users can customize heating curves based on process requirements, but exceeding this limit is not recommended to avoid affecting heating element lifespan or product performance.

   • The furnace chamber uses air as the working atmosphere, eliminating the need for additional protective gases, making it suitable for conventional heat treatment processes.

2. Control and Monitoring

   • Equipped with 2 temperature control points for precise regulation of the working zone temperature, ensuring stability within the set range.

   • Features 2 temperature measurement points for real-time monitoring of the heating chamber temperature, facilitating process control and data recording.

   • Uses K-type thermocouples as temperature sensors, known for their wide measurement range, stability, and fast response, making them ideal for high-temperature applications.

3. Furnace Chamber and Heating System

   • Effective chamber dimensions: 750mm (W) × 2000mm (D) × 900mm (H), capable of accommodating large batches of materials.

   • The chamber is constructed from SUS310S stainless steel, offering excellent high-temperature resistance, oxidation resistance, and corrosion resistance, suitable for prolonged high-temperature operation.

   • Heating elements consist of stainless steel heating tubes, featuring high thermal efficiency, low thermal inertia, and long service life, making them a common choice for high-temperature heating.

   • Maximum heating power: 90 kW, enabling rapid heating for efficient production. In standby mode, power consumption can be maintained below 45 kW, demonstrating energy-saving performance.

   • Surface temperature rise ≤35°C, indicating superior insulation that ensures operator safety and minimizes heat loss to the environment.

4. Loading and Material Handling

   • Uses SUS310S stainless steel racks arranged in a 3-layer × 3-column layout. Each layer can hold trays containing crucibles, with detachable tray designs for easy loading and cleaning.

   • Maximum load per rack layer: 40 kg. Overloading is prohibited to ensure temperature uniformity and structural safety.

   • Users must provide their own crucibles (specification: φ400 × 200 mm, cylindrical), suitable for heat treatment processes in ceramics, powder metallurgy, or related industries.

5. Program Control and Safety Protection

   • Supports 20-step program control, allowing users to preset multi-stage temperature, time, and process parameters for complex heating, holding, and cooling processes.

   • Includes multiple alarm protections: overtemperature, thermocouple failure, low air pressure, low water pressure, etc. All anomalies trigger audible and visual alarms to prompt timely intervention, ensuring equipment and operator safety.

   • Fan overcurrent protection prevents motor damage due to excessive load.

   • Complies with surface temperature rise ≤35°C requirements, maintaining safe exterior temperatures and reducing heat dissipation hazards.

6. Air Circulation System

   • Equipped with a dual-circulation fan system, with a total air circulation range of (5000-6800 m³/h) × 2. This dual-fan configuration significantly improves temperature uniformity and heat exchange efficiency, ensuring consistent material heating.

III. Normal Operating Conditions

To ensure safe, stable, and long-term efficient operation of the HRF1350-06 Hot Air Car Furnace, the following environmental, power, and auxiliary system requirements must be met:

1. Environmental Conditions

   • Ambient temperature: 0-40°C, relative humidity ≤80% RH. Avoid corrosive gases or strong airflows to prevent impacts on furnace temperature fields and component lifespan.

2. Air Supply (Intake)

   • Requires dry, clean, oil-free compressed air at 0.2-0.4 MPa, with consumption of 15-30 m³/h (varies by operating state).

   • Air quality directly affects furnace atmosphere and component longevity. Recommend installing filters and dryers for air treatment.

3. Cooling Water Requirements

   • For water-cooled components (e.g., electrical cabinet or specific heating elements), use clean, non-corrosive water at ≤23°C, 0.2-0.4 MPa pressure, and a flow rate of 6-18 L/min.

   • Adjust and maintain the water circulation system as needed.

4. Ventilation System

   • Exhaust must be non-contact connected to a user-provided extraction system (e.g., ducts or fume hoods) with capacity >40 m³/h to expel fumes, hot air, or volatiles, ensuring a safe workshop environment.

5. Electrical Requirements

   • Three-phase five-wire power supply: three live wires (yellow, green, red), one neutral (blue), one ground (yellow-green). Voltage: 380V (main)/220V (auxiliary), 50 Hz.

   • Total power capacity >130 kVA to ensure stable current during heating and prevent voltage fluctuations affecting temperature control or equipment lifespan.

   • Wiring must comply with standards, especially ensuring reliable grounding for operator and equipment safety.
