Graphite and Carbon Electrodes

Carbon Electrodes

SGL Group has more than 100 years of experience in the manufacture of carbon electrodes. Over the years we have worked to increase the quality of our amorphous carbon electrodes. In our technology and innovation center in Meitingen our continuous improvement efforts ensure that our electrodes meet the ever-growing requirements of our customers.

Cathodes and Furnace Linings

Cathode Blocks for Aluminum Electrolysis Cells

One of the key products of the Performance Products Business Unit is cathodes. Cathode blocks are used in the lining of aluminum electrolysis cells. Sidewall blocks, ramming pastes and special glues round up the cathode product portfolio - providing complete custom-made solutions to optimally fit the requirements in the Aluminum Smelter. SGL Group is the only independent cathode supplier offering the complete product range from amorphous, graphitic and graphitised cathodes. In addition, the Technical Service provides professional and highly qualified support around the application of cathodes, sidewalls, ramming pastes in customers` processes. The continuous development of next generation products supports optimal solutions to the increasing challenges in the smelting process such as cell life, productivity, and energy efficiency. SGL Group serves the leading Aluminium producers.

Equipment Solutions

Quenchers for Cooling Flue Gases

Quenchers are used to cool down flue gases or to dissolve gases rapidly by inducing a solvent. If aggressive gas components are present, graphite is the prime choice of material. Our DIABON^® quenchers can be used in large volume processes involving gas temperatures up to 1600° C. The robust design without moving parts is hardly impaired by dust particles and provides excellent production efficiency.

Rupture Discs

Rupture discs are used to assure high safety standards for operators and equipment in plants by avoiding uncontrolled pressure built-ups. Processing of aggressive media requires the use of corrosion resistant rupture discs. Our high quality DIABON^® graphite safety discs are characterised by precise threshold pattern with large opening of the tube cross section in case of activation.

POLYFLURON - Expansion Joints / Bellows

POLYFLURON bellows have a unique combination of outstanding properties and are suitable for very diverse applications. Because of their near-universal corrosion resistance, they are used particularly as components in chemical plants.
