Rongxing has app. 28 years' Carbon & Graphite product manufacturing experience since 1992,company is located at Zhengzhou city,China.
We pay much attention on mechanical developing and technology innovation.Now we have vibratory shaping equipment,synchronism shearing,press vacuum technic,high accuracy CNC machine tool,auto-batching system etc.
Now our products include:
Carbon pre-baked anode,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.
Our products are exported to Pakistan, Malaysia, Russia, Oman, Iran, Egypt, Czech Republic, Slovenia, etc. approx 20 countries and regions.And are well commended both in domestic and abroad.
What is Carbon prebaked anode?
In smelters running with prebake technology, Carbon Anodes, consisting of calcined petroleum coke and coal tar pitch as a binder are consumed.
Rongxing could supply can supply any size of Anodes under spot or long-term agreements.
We believe that being focused on the process of high quality manufacturing gives us an unmatched perspective of the challenges facing consumers and suppliers. Additional to the raw materials we are therefore capable with our inhouse Engineering Division to provide support and an in depth understanding of the individual requirements.

Pre-baked Carbon Anode application
Prebaked Carbon Anodes are a particular type of consumable electrodes (anodes) designed for aluminium smelting through the Hall-Héroult process. During the smelting process, these carbon anodes are suspended within the electrolysis cell(s) containing the electrolyte, which is primarily aluminium oxide (Al2O3). In the process, prebaked anode is consumed at a rate of approximately 450 kg of anode per tonne of liquid aluminium produced.
Main Featrues
- Low ash and high strength
- Low electrical receptivity
- made from the qualified petroleum coke and coal tar pitch
- Optimization of the baking process
- Few impurities
- Tailor-made production covering mould and specification
