Key Features of Our Roller Hearth Furnace

1. Energy-Efficient Design

The Roller Hearth Furnace is engineered with optimized insulation and high thermal efficiency, resulting in low energy consumption. The total heating power typically accounts for 35%–45% of the total equipment power, with advanced insulation materials minimizing heat loss during operation.

2. High-Temperature Capability

This High Temperature Roller Hearth Furnace achieves a maximum working temperature of up to 1200°C, making it suitable for applications like ceramic substrate firing, chemical powder sintering, and other high-heat treatment processes requiring consistent temperature control.

3. Adjustable Conveyor Speed

The conveyor speed in this Continuous Roller Hearth Furnace is fully adjustable from 0 to 300 mm/min, allowing for precise control over sintering time and drying processes. This adjustability helps achieve optimal thermal profiles for different material types and production needs.

4. Precise Temperature Control

Equipped with an advanced PLC control system and touchscreen interface, the furnace offers temperature control accuracy up to ±0.1°C. Using Delta temperature control modules, the system ensures stable operation with minimal temperature fluctuations. The temperature uniformity under no-load conditions is ≤±5°C, ensuring consistent heat distribution across the entire furnace length.

5. Durable and High-Quality Materials

The furnace lining uses a multi-layer composite structure, including lightweight bricks, insulating bricks, mullite-based insulation materials, and ceramic fiber layers, ensuring durability and excellent thermal insulation. The hearth features high-alumina refractory bricks, extending the service life of the furnace under continuous high-temperature conditions.

6. Customizable Heating Zones

This Roller Hearth Furnace supports customizable heating zone configurations, with each zone independently controlled for temperature precision. This modular zoning ensures uniform heating and flexibility for various production requirements, making it an excellent choice for powder sintering furnace applications.

7. Advanced Heating Elements

Using OCr21A6Nb high-temperature alloy wire heating elements, the furnace ensures efficient, stable, and uniform heat generation. Each heating element is controlled via SCR (Silicon-Controlled Rectifier) power controllers, allowing for real-time power adjustment and fine temperature control across each heating zone.

8. Efficient Cooling System

The external shell temperature of the Roller Hearth Furnace remains controlled during operation. The shell temperature increase does not exceed ambient temperature by more than 15°C, and joint areas stay within 40°C above ambient, ensuring operator safety and energy conservation.
