Complete Product Range Providing Custom-Made Solutions
Extended Product Portfolio of Cathodes Sidewall blocks and ramming pastes round up the cathode product portfolio – providing complete custom-made isolutions to optimally fit the requirements in the Aluminum smelter.
Sidewall Blocks SGL Group supplies various grades of sidewall blocks including: Amorphous, Graphitic and Graphitized to suit specific requirements for heat dissipation.
Sidewall blocks made from carbon and graphite
Ramming Pastes For cold application we have been manufacturing the ECO paste with lower PAH and a PAH-free paste thus making them more environmentally friendly than traditionally available pastes. High baked apparent densities, high compressive strengths and low specific electrical resistivities ramming paste materials.
