Heat treatment furnace facilities for the aluminum industry

HICON® roller-hearth furnaces for plates and sheets

Heat treatment processes for the manufacture of aerospace materials and aluminum materials in the automotive industry need to be able to handle a wide range of alloys cost-effectively.

Today, larger production quantities are heat treated exclusively in roller-hearth furnaces. Depending on the range of alloys and the quantity of materials to be processed, these facilities may be designed as continuous or semi-continuous furnaces for recrystallizing, tempering and solution heat treating with a quench immediately downstream of the furnace. In some cases the facility can be used for aging.

The facility is implemented to comply with the standards required by the automotive and aerospace industry. These standards are primarily AMS 2750E (SAE Aerospace) in the aircraft industry and CQI-9 (AIAG) for the automotive industry.

Advantages of the HICON® roller-hearth furnace:

  • low utility consumption per tonne processed
  • maximum heating up rate
  • damage-free transport through the facility
  • minimum temperature difference at end of soaking time
  • shortest overall facility length
  • highest possible cooling gradients
  • heavy-duty design for a long service life
  • prevention of distortion during quenching
  • easy to maintain
  • lowest emissions
  • quiet operation
