The carburiser materials have been widely used in the foundry industry, motivated by increasing use of scrap steel and consequent reduction in the use of pig iron. Several factors, besides of recovery of carbon in the metal bath, can be associated with the use of carburisers, including the effect on the levels of silicon, sulfur, nitrogen and degree of nucleation of metal. This paper evaluates the effects of the use of carburisers materials, of the types natural graphite, synthetic graphite, graphite permanent mold residue (used in molds of continuous casting) and synthetic graphite with low sulphur amount. The method of addition was chosen on the surface of the liquid bath, at a medium frequency induction furnace, 2500 kg capacity, tests a...
