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

I. Core Parameters of Sintering 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).

II. Temperature Control Cabinet Configuration

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).

III. Technical Highlights

1. Energy Efficiency
   • Ceramic fiberboard outer layer significantly reduces energy consumption, ideal for prolonged operation.

2. Safety & Reliability
   • Multi-layer alarms (over-temperature, thermocouple faults) ensure operational safety.

3. Flexibility
   • Reserved channels support future upgrades (e.g., multi-zone temperature control).

4. Global Quality
   • Eurotherm or Japanese instruments offer superior stability compared to standard domestic equipment.

IV. Notes
• 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.
