• Inside the furnace the big size pipes, to be heat-treated, are charged likewise on cantilever supported un-cooled rolls. However the rolls are mounted on a straight axis. The shells of the rolls are likewise of high heat resistant alloys. Individual gear motors and universal shafts drive the rolls.
• Once the pipe has been positioned at the centre of the furnace it is picked up by a mechanical transfer system from the stationary charging rolls and placed onto the fixed beam system.
• The moving and fixed beams of both furnaces are equipped with trough-type profiles and are of heat-resistant castings. This design ensures rotation of the pipes with each movement of the walking beam during the transport through the furnace.
• During furnace idling time or between cycle times the pipes are kept rotating at the spot.
• The walking beam frame of the furnace is driven by bell crank levers across tracks connected by tension and transverse rods. All rollers are equipped with anti-friction bearings and are connected to a central lubricating system.
• Hydraulic cylinders are provided for the lifting and lowering. Cylinder synchronisation is achieved through a synchronising shaft.
• After the pipes have been normalised, they are transferred to likewise cantilevers supposed discharge rolls. These rolls, however, are indirectly water cooled. The roll shells are of high heat resistant alloys.

Encon Group has the requisite expertise and capabilities in developing the creative, economical solutions of furnaces required for heat treatment of pipes, rods and bars. These furnaces can be either Batch or Continuous Roller hearth types with or without protective atmosphere. The Emerging Energy Efficient Furnace Builder & combustion solutions provider.
