Controlled Atmosphere Mesh Belt Continuous Tempering Furnace Heat Treatment OEM

1. Core Features & Technical Highlights

A. Multi-Atmosphere Precision Control

Supports N₂/O₂ (oxidizing) or N₂/H₂ (reducing) mixed atmospheres with 18 independent gas paths (including imported mass flow meters).

Oxygen content control: ≤10 ppm in high-temperature zone (with real-time monitoring via 4-point oxygen analyzers).

Safety interlock: Prevents simultaneous O₂/H₂ flow to avoid explosion risks.

B. High-Temperature Uniformity

15 heating zones (4.5m total length), each with 3-point (L/C/R) temperature control (uniformity ±3°C, stability ±1°C).

Heating elements: FEC heating plates + SUS310S double-layered muffle tube for thermal stability.

C. Efficient Cooling System

Hybrid cooling (gas + coil + water cooling) with adjustable flow rates.

Water-cooled section: Multi-stage design (3435mm length) for rapid workpiece cooling.

D. Smart Monitoring & Safety

DCS control system: Real-time monitoring of temperature, atmosphere, and conveyor speed; data logging/printing.

Multi-level alarms: Over-temperature, thermocouple failure, gas pressure anomalies, etc.

Emergency protection: Manual crank for power outages, emergency stop buttons at inlet/outlet.

2. Key Specifications

3. Safety & Maintenance

A. Gas Safety

Hydrogen handling: Leak checks mandatory; working pressure strictly 0.2-0.4 MPa.

Exhaust system: Ceramic igniters in chimneys burn residual H₂.

B. Operational Checks

Belt alignment: Regularly inspect tension/alignment to prevent wear.

Cooling system: Monitor water pressure/temperature to avoid scaling.

C. Installation Requirements

Space: ≥13m (L) × 3m (W), floor load >500 kg/m², humidity ≤80% RH.

Utilities: Dry compressed air (0.3-0.5 MPa) for exhaust assistance.

4. Typical Applications

MLCCs/varistors: Copper electrode sintering under N₂/H₂ (reducing) or N₂/O₂ (oxidizing) atmospheres.

High-precision sintering: Ideal for electronics requiring tight temperature/atmosphere control.

5. Recommended Workflow

Pre-start checks: Verify gas pressures, cooling water, and power stability.

Atmosphere switching: Purge furnace before switching between O₂/H₂.

Process optimization: Use DCS to fine-tune zone temperatures/gas flow rates.

6. Critical Notes

Power supply: Isolate from high-noise equipment (e.g., welders) to avoid interference.

Maintenance: Replace FEC heating elements if efficiency drops (>40 kW idle power).

This furnace combines precision heating, flexible atmosphere control, and industrial automation, making it suitable for high-volume production of advanced electronic components. Strict adherence to safety protocols is essential for optimal performance.

Applications:

Widely used in Used in the sintering process of copper electrodes for chip capacitors and varistors under N₂, H₂ or mixed atmosphere of N₂ and O₂.
