CS Additive
the carburising specialist
is expanding manufacturing operations









- Enhanced product and service offering for foundry and steel industry
- Reduced cost of production and less emissions
- New sales markets entered

CS Additive GmbH headquartered in Essen, Germany, is expanding its portfolio of products and services. At its site in Brüggen, North Rhine-Westphalia, Germany, the company is building a new plant to manufacture customised carbon formula-tions for the production of iron and steel. Storage and transport facilities simplifying the production process will be added as well. The company is spending ¤4.6 million to enhance its infrastructure in this way.

"Under the Carbolux® brand, we have been supplying our customers in the iron and steel industry reliably with acetylene coke of consistently high quality for more than 30 years, acquiring comprehensive expertise in the industry over this period," said Dr. Manfred Kühn, Managing Director of CS Additive GmbH. Having expanded its product offering to include graphite and anthracite in 2007 and 2009, as well as petroleum coke just recently, CS Additive now aims to enhance its services for customers. Kühn said, "Instead of offering just separate products, now we have all the products we need to supply our customers with package solutions of recar-burising agents that are customised to their specific requirements." CS Additive's experts will first analyse the characteristic profile of the requirement of the cus-tomer. Based on this they will customise a recarburiser to suit these individual needs. "This is an even better way for us to support the dynamic growth of our global customers in the iron and steel making industry. The new equipment also enables us to use enhanced product screening technology, so that we can supply customers in new markets who need carbon products to make brake pads," Kühn said.

The most important products of DIN ISO EN 9001:2008 certified CS Additive are produced on the basis of acetylene coke, which the company has been purchasing as a raw material from BASF of Ludwigshafen for more than 30 years to process it. Other products are based on graphite and anthracite. At its Herten, Germany, site CS Additive also upgrades sulphur, which it receives from oil refineries.

Iron foundries and steelworks appreciate the Brüggen site's products because they are excellently suited for adjusting prouduct, such as tensile strength, ductility and elasticity, hardness and thermal conductivity, to defined values. The sulphur prod-ucts of the Herten site are sold to the steel industry as alloying elements. Custom-ers in the tyre and rubber industries use these products as vulcanisation agents. In addition, specialty chemicals customers use the sulphur products to manufacture anti-corrosion paints, among other things.

The customer base of CA Additives is split roughly in two halves between the automotive and mechanical engineering industries. Long-time customers include, for example, the companies Siempelkamp, Saarstahl and Fritz Winter. Typical ap-plications of CS Additive's products are grey cast iron, ductile and vermicular cast iron, and cast steel, as well as tyre cord and heavy plate.

About CS Additive
CS Additive GmbH was founded in 2005 by a management buyout of business activities from RAG AG. Today, the company is one of the world's major manu-facturers of high-quality additives for steelworks, iron foundries and the chemical industry. The carbon and sulphur products reflected in the company's name are manufactured at sites in Brüggen and Herten, towns in North Rhine-Westphalia, Germany. In the past 10 years CS Additive implemented a variety of projects to protect the environment at its production sites, spending roughly ¤1.8 million in the process. In addition to an effective reduction in dust emissions, this included the use of waste heat for drying and to heat factories, warehouses and offices. Noise emissions and fresh water supplies used by the cooling system were also cut drastically. In 2011 CS Additive had 64 employees and posted sales of approxi-mately ¤27 million, selling its products to nearly 200 customers in more than 25 countries.
