Carbon Additives for Ductile 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 form of carbon additive available on the market today. Desulco® is the number one choice (charge and trim) recarburizer for ferrous foundries around the world.
How can we help address your challenges?
Over the past four decades, Desulco® has successfully been used as a charge carbon and ladle trim additive, for the production of steel, ductile and gray iron castings. Desulco® provides the greatest nucleating effect, which promotes improved mechanical properties. Its high carbon purity and low ash content assures rapid dissolution, more carbon units, and less slag formation for a cleaner alloy. Its consistently low sulfur and gas contents reduce ductile iron treatment cost and pig iron usage. Desulco® is available in various sizes for the intended application to assure rapid dissolution and high carbon recovery.
