Key Design Highlights:

1. High-Temperature Heating System:
   • Equipped with 1800-grade MoSi₂ heating elements on both sides, ensuring reliable operation under 1700℃.
   • Dual-zone temperature control (left and right) improves stability and uniformity.
2. Energy-Efficient Insulation & Structure:
   • Triple-layer insulation (High-alumina wool + alumina blanket + alumina fiber board).
   • Reinforced alumina hollow sphere panels at vulnerable points for durability.
   • Double-layer air-cooled shell keeps surface temperature below 45℃ while prolonging heating element life.
3. Automated Operation:
   • Motor-driven bogie hearth (1 ton capacity) with smooth movement and precise limit switches.
   • Step-lap sealing design prevents heat leakage and ensures consistent thermal performance.
4. Advanced Control & Protection:
   • 50-segment programmable temperature controller with PID/APID intelligent algorithms, ensuring stable heating without overshoot.
   • Thyristor phase-angle control for soft start and constant power output.
   • Multi-level protection system against overcurrent, overtemperature, thermocouple failure, power loss, and more.
