Light Gray Casing Vertical Atmosphere Box Furnace PID Auto-tuning Atmosphere Box Furnace

1. Temperature Performance

• Rated Temperature: 1300°C (standard operating range)
• Maximum Temperature: 1500°C (short-term limit; material tolerance must be considered)
• Usage Tip: Evaluate the lifespan of sintering plates and refractory materials when exceeding 1300°C.

2. Furnace Structure

• Effective Dimensions: 400×330×800mm (W×H×D), suitable for small to medium-sized workpieces.
• Sintering Plate: Made of corundum mullite, offering high-temperature resistance and chemical stability.
• Refractory Materials:
  • Inner Layer: Polycrystalline mullite (high insulation, thermal shock resistance)
  • Outer Layer: Ceramic fiberboard (lightweight insulation, significant energy savings)

3. Monitoring & Expandability

• Pre-installed thermocouple ports and temperature monitoring holes support multi-point measurement or upgrades.

4. Exterior & Color

• Dimensions: 850×900×1200mm
• Light gray casing (standard industrial color)

1. Temperature Control Channels

• 5+2 channel design: 5 channels directly connected to the furnace, 2 channels reserved (flexible expansion/redundancy)
• Instrument Count: 7 temperature controllers (independent control per channel for precision)

2. Control Instruments

• Models: Eurotherm 3504 or Japanese imports (international brands, high reliability)
• Key Features:
  • PID auto-tuning (automatically optimizes heating curves)
  • High-temperature alarms, thermocouple failure alerts (comprehensive safety)
  • Power/voltage modulation (precise adjustments to minimize fluctuations)

3. Over-Temperature Protection

• Dual safeguards: audible/visual alarms + heating cutoff to prevent equipment/workpiece damage

4. Exterior & Color

• Dimensions: 800×1850×500mm (vertical design, space-saving)
• Color: Light gray (matches the furnace)

• Energy Efficiency: Ceramic fiberboard outer layer significantly reduces energy consumption, ideal for prolonged operation
• Safety & Reliability: Multi-layer alarms (over-temperature, thermocouple faults) ensure operational safety
• Flexibility: Reserved channels support future upgrades (e.g., multi-zone temperature control)
• Global Quality: Eurotherm or Japanese instruments offer superior stability compared to standard domestic equipment

• Temperature Matching: Ensure workpiece sintering processes stay within 1300°C to avoid frequent over-temperature use
• Maintenance: Regularly inspect thermocouples and refractory materials, especially after prolonged high-temperature operation
• Training: Operators must master PID parameter adjustments and alarm handling procedures

1. The equipment must be installed indoors, with an ambient temperature range of -10℃ to 45℃. The indoor environment must be free of flammable gases, corrosive gases, and vapors.
2. The equipment requires a floor space of no less than 4 square meters, with a working area length of at least 2 meters, width of at least 2 meters, and height of no less than 3 meters. The foundation must be sturdy and level, and the furnace weighs approximately 400kg.
3. The power supply for this furnace must be a three-phase five-wire AC power line, with a voltage of 380±10% V and a frequency of 50±2% Hz. This power line is dedicated, and high-power conversion equipment such as welding machines, electric furnaces, and metal-cutting machine tools should not be connected to this distribution.
4. The equipment must be reliably grounded.
