UHP 500mm2400mm Graphite Electrode for Metal Smelting
Company Description:
Rongxing carbon established in 1992, after twenty years development, we has formed our own production system: electrode paste and recarburizers (including anthracite carburant, calcined petroleum coke carburant, graphite recarburizer) are core products, and also produce pre-baked anode, anode scrap, carbon brick coal and petroleum coke.
We are a manufacturer and trading combo,special in the carbon&graphite procuts for 24 years. The main products is EP(electrode paste),GE(graphite eletrode), (CPC)calcined petroleum coke, and also do trading for other carbon and graphite items.
Our carbon and graphite items have passed the testing specific carbon testing according to JB/T6773-2011.We're sure that the material is in striectly accordance to REACH regalation for EU market.
Annual output:50,000tons graphite electrode
200,000tons electrode paste
200,000tons calcined petroleum coke
