Aluminium melting with AIROX at SAG in Lend, Austria.

Aluminum Melting Achieving increased productivity and yield, reduced energy consumption and emissions, enhanced quality.

Melting is one of the core steps for processing secondary aluminum. This step is energy intensive and impacts both the productivity and total cost of your aluminum production.


Application technologies for aluminum melting

Low-temperature oxyfuel combustion technologies (LTOF)

This leading technology works as follows: With low-temperature oxyfuel combustion technology, the burner flame is diluted by the re-circulation of furnace gases, lowering the flame temperature.

Highlights

  • More homogenous heating of the furnace
  • Higher productivity and energy savings
  • Less dross and ultra-low NOx emissions

WASTOX® combustion process

Our advanced WASTOX® combustion process burns off unwanted combustibles directly in the melting furnace.

Highlights

  • Allows higher organic content in the feedstock
  • Tight process and emission control
  • Lower energy consumption
  • Suitable for any furnace

AIROX® combustion technologies

With our AIROX® combustion technologies, furnace operators can easily switch between oxygen or oxygen-enriched gases during the melting process and air during the holding phase.

Highlights

  • Flexibility with easy switch from melting to holding phase
  • Greater melting capacity
  • Lower energy consumption
  • Lower emission rates

Melt purging technology

Our purging technologies employ nitrogen or nitrogen mixtures to generate bath movement and enable hydrogen removal in aluminum melting.

Highlights

  • Improved heat transfer in metal bath
  • Temperature homogenisation
  • Quality improvement through hydrogen removal

OXYGON® 400

OXYGON® 400 is a ladle preheating system that utilises flameless oxyfuel combustion to heat vessels and ladles that are used to transfer for hot, liquid metal between melting and casting operations.

Highlights

  • Shorter heating times and greater capacity
  • Improved fuel economy and reduced emissions
  • Extended vessel refractory lining life
