The design of fast heating furnace is suitable for any kind of combustible gas.
Thermal efficiency - higher than 55% - is obtained by recovering heat energy from product combustion.
The temperature of the billet is controlled in each area of the furnace, and the surface of the billet is directly contacted by the thermocouple.
The reasonable design ensures the simplicity of its maintenance.
Gradient heating between furnaces allows the formation of the possible maximum temperature gradient between the head and the tail at - 50 C per meter, which is suitable for production requirements.
Greater gradients can be obtained by installing quenching systems - averaging more than 100 C per meter.
By combining quenching system with excessive heating of billet in fast heating furnace, the extrusion speed can be greatly increased up to 50%, especially in the production of special alloy.
