Roller Hearth Kiln

Electric Heated Roller Hearth Kiln

The Roller Hearth Kiln is a high-efficiency continuous tunnel kiln. The equipment adopts a roller drive structure to achieve continuous feeding and discharging, resulting in significantly higher production efficiency and product consistency.The kiln body adopts a steel structure assembly design, combined with high-performance refractory insulation materials, providing excellent energy-saving effects and stable temperature control.

Produit Fonctiounen (Roller Hearth Kiln)

  1. Roller Drive, Continuous and Efficient Production

This electrically heated roller kiln is a roller tunnel kiln that uses a roller drive system. The material is placed on rollers and moved forward by the continuous rotation of the rollers, making it suitable for large-scale continuous production. Equipped with a frequency converter and a geared motor, it runs smoothly and can be steplessly speed-regulated. The residence time can be flexibly adjusted according to the material characteristics and process requirements.

  1. High-Quality Lining, Insulation and Energy Saving

The kiln lining is constructed of alumina fiberboard and refractory insulation materials, resulting in low heat storage, Resistenz géint séier Heizung a Killmëttel, and excellent insulation. The multi-layer composite insulation structure minimizes heat loss and significantly reduces energy consumption.

  1. Multi-Zone Independent Temperature Control, Precise Temperature Curves

Multiple independent heating zones are set along the length of the kiln. Each zone can be individually temperature-set, achieving precise temperature curve control for preheating, sinteren, an Ofkillung, meeting the requirements of complex sintering processes.

  1. Kontinuéierlech Produktioun, High Degree of Automation

The equipment can continuously feed and discharge materials. Combined with an automatic temperature control system and a variable frequency speed control system, it achieves fully automated operation, reducing labor costs and improving production efficiency.

  1. Applicable to Multiple Material Forms

Suitable for sintering and high-temperature treatment of various material forms such as flakes, plates, blocks, and powders, with a wide range of applications.

Main Advantages of Roller Hearth Kiln1. Due to the small cross-section of the kiln and the ability to heat simultaneously above and below the roller table, the heating rate is fast, and the temperature distribution in the kiln is relatively uniform. The temperature difference between the top and bottom generally does not exceed 5℃, which creates conditions for rapid firing and improving product quality. Zum Beispill, when used for decoration firing, it can ensure consistent color, brightness and vividness.
2. The roller hearth kiln does not use kiln cars or saggers, only some refractory pads, and some even do not use pads. Dofir, the heat consumption is greatly reduced, and fuel is significantly saved.
3. It is conducive to the mechanization and automation of the firing process (loading, firing, cooling, unloading), facilitating the connection of upper and lower processes, forming a complete continuous production line, and improving production efficiency.
4. Simple structure, low cost, easy maintenance and convenient operation.
5. Reduces labor intensity and improves the working environment.
