Velaverkstaedi Hjalta Einarssonar ehf. - VHE of Iceland - manufactures a range of Anode Stub Graphite Coating Systems.
In the past, rodding plants often used an organic solvent and graphite mixture which quickly dried at ambient temperatures. Environmental considerations have largely eliminated this practice and today most smelters use an aqueous graphite suspension. The use of water as the diluent means that careful drying is necessary to eliminate the risk of dangerous steam explosions during the anode sealing process.
VHE's Anode Stub Graphite Coating Systems comprise a graphite coating tank and a drying system. The coating tank contains an aqueous graphite suspension and is elevated to the anode rod by hydraulic or pneumatic rams such that the anode stubs are partially immersed in the graphite mixture. The graphite is kept in suspension by continuous agitation of the tank contents.
