Feartures

Furnace Casing

- The casing is made of Q235 low-carbon steel with an electrostatic anti-corrosion coating, providing excellent corrosion resistance.

- It features a robust metal frame structure with a low surface temperature during operation.

- The side-swing door design allows the door to open to the right, ensuring convenient operation.

Refractory Material
- A multi-layer insulation design composed of lightweight alumina ceramic fiber and high-quality insulation board backing, free of asbestos. This structure minimizes heat loss and reduces energy consumption.

Heating System

- High-quality Silicon molybdenum rod heating elements are securely installed on both sides of the furnace chamber, enabling efficient radiant heating and ensuring long service life.

- Dual-side heating (left and right) ensures excellent temperature uniformity within the furnace.

- A silicon carbide base plate covers and protects the bottom heating elements, offering high mechanical strength, superior thermal conductivity, and horizontal load-bearing capacity.

Temperature Control Panel

- PID combined with SSR (Solid State Relay) control ensures precise temperature regulation.
- An internationally standardized S-type platinum-rhodium thermocouple provides a temperature measurement range of 0-1800°C and extended durability.
- The furnace door is equipped with a safety interlock switch that cuts off power when opened.

Program Controller

- A controller designed to meet complex process requirements.

- Simple and direct operation with flexible programming capabilities.

- Supports programming of 4 curves, with each curve containing 8 segments.

- Features over-temperature and malfunction alarms with automatic protection functions.
