Elgraph® Superior recarburiser

Elgraph® Superior Grade recarburiser is specially formulated as a carbon raiser for ductile iron, with particular emphasis on high purity, high carbon recovery, rapid 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 phaseof melt preparation.

The technology developed for Elgraph® Superior is based on knowledge gained from 100 years of Elkem electrode paste production. Selection, control and testing of raw materials optimise production based on customer needs. Our high-temperature electric calcining process ensures maximum crystallinity of the final product which enhances purity and solubility. Elgraph® Superior recarburiser is available in size grading 0-0.5mm and 0.5 - 5mm.

  • High carbon recovery
  • Easy, rapid solubility even with low agitation
  • Consistent quality due to continuous production process
  • Ideal for carbon trimming just prior to casting
  • Low nitrogen/hydrogen levels reduce pinhole risk
