Products classified under HTS 8545.11.00.50
Soderberg Electrode for Aluminum Smelting Furnace
A large baked carbon electrode used in Soderberg aluminum smelting furnaces to conduct electricity for electrolytic reduction of alumina. It consists of a continuous self-baking paste of calcined petroleum coke and coal tar pitch, formed around a steel casing. Classified under HTS 8545.11.0050 as 'other' electrodes of a kind used for furnaces, distinct from smaller electrodes.
Graphite Electrode UHP 600mm for Steel Arc Furnace
Ultra-high power (UHP) graphite electrode, 600mm diameter, manufactured from needle coke and graphitized at high temperatures for use in AC electric arc furnaces for steel production. It provides high electrical conductivity and thermal resistance in melting scrap steel. Falls under HTS 8545.11.0050 as 'other' furnace electrodes not specified elsewhere.
Prebaked Carbon Electrode for Ferroalloy Production Furnace
Prebaked carbon electrodes used in submerged arc furnaces for producing ferroalloys like ferrosilicon and ferromanganese. Made from anthracite coal and metallurgical coke, these electrodes conduct current through the charge for high-temperature reduction. HTS 8545.11.0050 covers these as 'other' furnace electrodes.
Large Diameter Graphite Electrode for EAF Steel Refining
700mm diameter regular power (RP) graphite electrode for electric arc furnace (EAF) steel refining, featuring low electrical resistivity for sustained arcing. Composed of petroleum needle coke, it withstands extreme temperatures in ladle furnace refining. Classified in 8545.11.0050 as other furnace electrodes.
