ELGRAPH® - Recarburisers

ELGRAPH ® recarburisers are carbon additives manufactured at high temperatures from selected raw materials specifically for use as re­carburisers during cast iron and steel pro­duc­ti­on Elkem’s production process, with continuous calcining up to 3000 °C, gives an extremely stable product, where the high performance is constant, vs many other materials in the market (often based on a batch process or sourced graphite).

Advantages of the  ELGRAPH® recarburisers are:

  • High carbon recoveries
  • Easily rapid solubility even at low agitation
  • Consistent quality due to continuous production process
  • Carbon trimming just prior to casting
  • Very low nitrogen/hydrogen levels reduce pinhole risk

 

ELGRAPH® Superior recarburiser

ELGRAPH® Superior Grade+ recarburiser is espe­ci­ally formulated as a carbon raiser for ductile iron, with particular emphasis on high purity, high carbon recovery, excellent so­lu­bi­lity and very low content of sulphur, nitro­gen and hydrogen. It may also be used for final trimming of grey iron. Its high dissolution rate makes it very suitable in the carbon adjustment phase of metal preparation.

  • ELGRAPH® Superior recarburiser has a typical electrical resistivity of 50 - 60 µOhmm.
  • ELGRAPH® Superior recarburiser is available in size grading 0,5 - 5 mm and 0,5 - 5 mm.

 

ELGRAPH® Premium recarburiser

ELGRAPH® Premium  Recarburiser is specially formulated as a carbon raiser for steel and grey iron castings, with particular emphasis on high purity, rapid solubility and good reproducibility. ELGRAPH® Premium Grade Re­car­bu­riser with its low nitrogen content is especially suited for pro­duc­tion of grey and ductile cast irons.

  • ELGRAPH®Premium recarburiser has a typical electrical resistivity of 100 -300 µOhm.
  • ELGRAPH® Premium recarburiser is available in size grading 0-0.5 mm and 0,5 - 5 mm.
