MOULD TUBES

The performance requirements that have to be met by moulds and mould materials depend on the specific application and the levels of stress involved. These stress levels are mainly predetermined by the machine and casting parameters, which means that many different cast shapes are needed, depending on the type and construction of the mould. KME develops and supplies the whole range of mould tube geometries and dimensions in use today, from small rectangular tubes right through to large-format round mould tubes. Our customers can select from various tapers and special internal geometries, such as Wave Mould Tubes or Textured Mould Tubes.


WAVE MOULD TUBES

CHALLENGE:

  • Reduce billet rhomboidity and improve billet shape

SOLUTION:

  • WAVE mould having special internal geometry (KME patent pending) for a better guidance of the steel strand through the mould.

APPLICATION:

  • Billet and bloom moulds in all copper alloys
  • Compatible with existing equipment.

ADVANTAGES:

  • Reduced billet rhomboidity
  • Improved billet shape
  • Improved internal billet quality
  • More uniform shell growth
  • Less „snaking“ of the billet
  • Increased mould life

TEXTURED MOULD TUBES

CHALLENGE:

  • Controlling mould heat removal to improve billet shape and product quality.

SOLUTION:

  • Macro texturing on mould hot face in upper zone.

APPLICATION:

  • All mould tube types

ADVANTAGES:

  • Moderated heat transfer in specific areas of the mould
  • Improved strand quality due to more uniform shell growth
  • Reduced billet rhomboidity
  • Increased mould life due to reduced thermal load

ADVANCED TUBE MOULDS

CHALLENGE:

  • Eliminate corner gaps
  • Improve uniformity of mould cooling

SOLUTION:

  • Replace traditional four-piece bloom mould plate with one-piece mould tube design
  • Thin-walled copper tube design
  • Uniform water gap cooling design
  • Low stress AFM® mounting technology (KME patent)

APPLICATION:

  • All bloom moulds

ADVANTAGES:

  • Optimized cooling conditions
  • Homogeneous temperature profile of bloom
  • Increased average heat transfer rate
  • Improved strand quality
  • Repair by inside copper coating and mechanical machining
  • Longer lifetime and reduced maintenance costs


SPECIAL SHAPES

To optimize the casting process and product quality even more, KME offers innovative detailed solutions that can be combined to suit the customer’s specific needs for solving metallurgical or process-related technical problems. Our customers can select from various tapers and special internal geometries, such as Beam Blank Mould, Convex or DiaMold® tubes.
