The tunnel furnaces are modular in structure and do not require a foundation. As a result, they can be designed with a whole range of lengths and widths to meet your requirements.
The oven is insulated with a light refractory lining and ceramic fibre modules, and can operate at temperatures of up to and above 1250°C. It is possible to set the required temperature of various self-regulated areas and thereby determine the heating and cooling processes.
Depending on the situation, products can be fed into the furnaces as follows:
- On plates made of refractory steel (hydraulic pusher) load on wagons pushed together by pusher
- On plates made of refractory steel and supported by motorized ceramic rollers.
Shell moulds can be heated using:
- Natural gas or LPG burners
- Electric heating elements
