Superior Graphite is recognized as the world’s leader in providing the iron and steel industries with desired, high-value graphite/carbon solutions.  The company is international is scope and provides advanced products, with technical services, to customers in more than 40 countries. 

 Since 1917, Superior Graphite has been providing its customers with graphite/carbon materials to solve metallurgical, as well as production, process problems.  The company’s knowledge-based employees, coupled with its unique high temperature manufacturing technologies, enable it to offer materials desired by the industries it serves.  

Unique Capabilities  

Superior Graphite operates two different electrothermal continuous process technologies, which, in turn, provide high-value end graphite/carbon products to its customers.  In tandem with these technologies is a knowledgeable, flexible work force prepared to provide excellent innovative product support services.  A sophisticated distributor/agent network complements Superior Graphite’s worldwide direct employees.

In Hopkinsville, KY, and Sundsvall, Sweden, the company operates a proprietary continuous manufacturing process that thermally purifies granular carbon based materials in temperatures typically at 2,500°C.

This Statistically Process-Controlled technology is focused to produce a number of distinctly different specialized graphite/carbon materials.  The most widely recognized finished product from this technology is trade-named Desulco®.  Desulco® is a precision-engineered granular carbon additive used extensively in the ferrous making process where carbon performance is critical.  Important Desulco® high-value characteristics are: consistency, reliability and predictability.  Typical product properties are 99.9% C, 0.015% S, and under 100 PPM gas levels.  Desulco® is the product of choice replacing synthetic graphite and cokes in the production of ductile iron, gray iron, carbon steel, special quality steels, and steel ladle refining stations.  Over 1,000,000 tons of Desulco® have been shipped to customers worldwide without a quality defect.

In Russellville, AR, the company is uniquely focused on manufacturing mid-size diameter (200mm – 400mm) Ark® graphite electrodes used in electric arc furnaces.  Ark® electrodes benefit from a unique continuous graphitizing technology that imparts  very uniform and consistent properties on each piece.  Other electrodes on the market are produced in Acheson batch furnaces.  This Acheson process was developed in the late 1800’s.  Again, ultra-high temperatures exceeding 2,500ºC are controlled to exacting standards to produce problem-free Ark® graphite electrodes.  Finished products have earned a worldwide reputation for dependable, trouble-free, consistently high-value performance.  Like all Superior Graphite product offerings, Ark® graphite electrodes are performance-benchmarked by technical field engineers throughout the world.
