Forging rotary hearth furnace able to treat parts that weigh up to 500 kg each for a production capacity of 2.000 kg/h with temperatures up to 1.300 °C. Heating is via radiant flame burners with a centralized heat recovery system to preheat combustion air up to 500 °C. The entire insulation is made of refractory casting. A vertical wall in between the loading and unloading doors reduces thermal losses during open door operations.
