This roller kiln is particularly suitable for applications requiring strict thermal curves, stable production cycles, and large-scale continuous processing.
The 22-meter roller hearth kiln is a high-efficiency continuous heat treatment furnace, designed for precise thermal processing of ceramics, electronic components, metallurgical powders, and other advanced materials.
With 5 heating zones and 20 independent temperature control points, it ensures exceptional uniformity with cross-sectional temperature deviation ≤ ±5℃ and control accuracy ≤ ±1℃. The optimized power distribution, advanced PID + SCR control system, and durable heating elements provide both reliability and energy efficiency.
