The rotary furnace hearth is driven by an electric gearmotor. The pinion meshes with a circular rack that has been cast to form an integral part of the hearth. The weight of the hearth and charge material is supported by one or more series of bevel gears fastened to the foundation. A large rolling bearing is responsible for centring the hearth. Movement is controlled by means of an absolute encoder that ensures sufficient indexing precision for the automatic loading and unloading systems.
The combustion system is based on the use of ultra-low NOx regenerative burners with high thermal efficiency.
Burners feature a regenerator, pilot burner, control/shutoff valves and reversing valves for switching between combustion and exhaust mode.
Continuous control of the fan tasked with fume extraction keeps pressure constant inside the furnace.
Rotary furnaces are managed via supervisory software designed to be able to communicate both with the company supervisory system and with the robotic loading/unloading system, if any, in order to automate material tracking and production flow.
