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 HRE spiral resistance wire heating elements are firmly embedded into the furnace surface, enabling free radiant heating within the chamber and offering a long service life.

- Three-side heating (left, right, and bottom) ensures excellent temperature uniformity inside the furnace.

- The silicon carbide base plate covers and protects the bottom heating elements, providing high mechanical strength, excellent thermal conductivity, and horizontal load-bearing capacity.

Temperature Control Panel

- PID combined with SSR control ensures precise temperature regulation.

- An internationally standardized N-type nickel-chromium-silicon thermocouple offers a temperature measurement range of 0-1300°C and a long service life.

- The furnace door is equipped with a power-cut safety switch 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.
