Carbonaceous materials are typically used as melt covers over pure copper, brass and bronze or other copper alloys, to prevent oxidation of the melt and to deter formation of oxide slag. While various materials can be used, high purity materials provide a high level of protection with a minimum amount of contamination. To meet this challenge, Superior Graphite developed DesulcoMC®, …

Producing the appropriate carbon level in steel is of critical importance in order to create the desired characteristics of the final product. These include tensile strength, yield strength, hardness, and other physical properties. In steel production, Desulco® is typically used in high grade steels, such as medium to high carbon steels (0.5% – 0.8% C), steel cord (wire mesh for …

Poor base iron nucleation and inoculation can be a typical cause for the formation of poor graphite structures in both gray and ductile irons, which can ultimately lead to the desired mechanical and physical properties not being met. The morphology, chemistry and crystallinity of the recarburizer material can have a major impact on the overall metallurgical quality of the iron. …

Ductile Iron foundries use a variety of carbon additives to increase the carbon content of the melt in order to provide a number of beneficial characteristics. The iron must have a specific carbon level to attain the proper carbon equivalent (CE) in order to achieve the desired mechanical properties. To meet this challenge, Superior Graphite has developed Desulco®, the purest …
