Preheating

Ideal application for many strip processing lines

The most requested application is for increased production. An increase of up to 30% is typical and can be achieved in a very short heating length prior to a furnace. Several thousand kilowatts can be installed in a single heating coil.

Heating prior to pickling has many advantages. Operating costs can be substantially reduced due to several factors, such as:

  • Lower acid concentration and less usage
  • Lower vapor content in the atmosphere
  • Lower acid concentration in the waste
  • Lower water treatment costs

Ultra rapid anneal is an application of preheating prior to a silicon steel decarburizing furnace. Heating to 770°C (1420°F) is typical and results in superior silicon steel electrical properties.
