Showa Denko Carbon Germany GmbH

records EAF production and control data directly from customer PLC systems for off-site analysis. Data is only transmitted with the customers’ consent and data confidentiality is maintained at all times.

CEDIS® gleans out the most important bits of that data and provides daily, weekly, and monthly summaries along with analysis, and highlighted outliers to quickly provide alerts. It is customized to each EAF where it is installed in order to meet the individual needs of the particular shop.

Our experts analyse CEDIS data systematically to find potentials for process optimization and make recommendations for improvement projects to customers. Graphs and tailored reports created from CEDIS data can be very helpful for visualizing long-term trends in process Parameters.

In addition, we help customers to improve furnace productivity with a range of value-adding services such as:

– Consumption model – to check against benchmarks

– theoretical and real consumption data

– Calculation of productivity increase

– Recommendations for EAF design

– operational best practise workshops

– Furnace start-up assistance

– Electrical energy modeling

– Regulation tuning

– Hydraulics

– Power (melting) profiles

SDK is the global leader in Graphite Electrodes for Electric Arc Furnaces. ECO PRO stands for EAF Control Optimization and Professional cooperation. The Team develops partnership projects together with the interested customer in order to collaborate and achieve improved customer results on a jointly agreed project scope.

Our highly qualified and experienced personnel employ Six Sigma techniques along with the customer’s own experience to find solutions applicable to the unique situation of the particular customer. Our goal is to reach a win-win situation. We believe that a project is successful if our customer is totally satisfied with the improvements achieved on completion of the project.


ECO PRO projects do not cover just electrodes but also everything around the EAF process. Successful projects carried out so far are related to topics such as:

– Higher efficiency

– Lower energy consumption

– Productivity increases

– Carbon / oxygen injection

– Chemical energy optimization

– Foamy slag

– Customized reporting (interaction with customer’s data – PLCs)

– Tailor-made data analysis

Graphite electrodes are used for the recycling of steel in the electric arc furnace industry, so called “mini-mills”. They are also used in the refining of steel as well as in the non ferrous industries, where smelting processes are in use. We do not simply provide graphite electrodes and connecting pins as standalone products to our customers. Rather, the focus is on the delivery of an entire “product system”, supported by sales and technical experts from the receipt of the customer’s order, throughout the entire production process, to final consumption in the steel plants.
