This tunnel kiln comprises of kiln cars and kiln modules, with the automatic kiln car handling system and control system. The concept is to provide a modern design and fabricated construction, offer the benefits of flexibility in operation and get more profits.


The kiln car is designed to be lightweight yet robust, featuring a double sealing structure (labyrinth) for optimal performance.


Interlock-seal between kiln car Double sealing

1. Mature energy-saving firing technology
2. Design and the selection of materials are advanced and reasonable
3. Low gas consumption
4. Low temperature on kiln outside surface and under the cars
5. Small temperature difference in kiln cross-section
6. High qualified rate of sintering
7. Fully automatic control, safe and reliable operation.


1. Kiln control system is developed independently by us, which is suitable for air/gas ratio control,pulse control and flow control according to different requirements of the production processing.
2. Kiln control system mainly select Siemens PLC module of S7-300 and S7-200 or OMRON PLC module of CJ2M, industrial control computer and touch screen.
3.This system can collect the signals of kiln temperature, the pressure, air flow, etc., then send these information to main control panel or management system to display, record, set and control.
4.Control system can record and mange klin data in Microsoft windows, you can easily inquire historial data for defect analysis.
