3. Advanced Structural Design

• Furnace Shell: The shell is made of high-strength welded and cast steel plates, providing excellent rigidity and stability under high temperatures. The pressure ring is crafted from cast iron to ensure strong mechanical support.

• Furnace Lining: The melting pool uses a one-time forming castable material with a compressive strength above 140MPa at 110℃ and a linear change rate of just 0.1%. The thermal insulation layer is built using premium aluminum silicate fiber board and lightweight firebricks, ensuring exceptional heat retention and minimal energy loss.

• Graphite Crucible: A Golden Elephant brand graphite crucible is included, offering high thermal conductivity, resistance to oxidation, and extended operational life.

4. Intelligent Gas Burning System

The pipeline burning system integrates automatic ignition, flame detection, and dual-stage flame control (big/small flame) to optimize combustion efficiency. The system automatically adjusts based on temperature thresholds, maintaining a stable melting environment.

Main Components of the Gas System:

• Honeywell – Flame detector, solenoid valve, ignition controller, and electric actuator

• Fiorentin – Gas pressure reducing valve

• CKD (Japan) – Ignition solenoid valve

• Astechnic (China) – High-performance gas burner
