This needle coke market analysis consid...Read more -
Recarburizer SemiGPC and GPC using in steelmaking
High-purity graphitized petroleum coke is made from high quality petroleum coke under a temperature of 2,500-3,500°C. As a high-purity carbon material, it has characteristics of high fixed carbon content, low sulfur, low ash, low porosity etc.It can be used as carbon raiser (Recarburizer) to pro...Read more -
Calcined Petroleum Coke Using in Aluminum Factory
The coke obtained from petrochemical industry cannot be directly used in the production of pre-baked anode and graphitized cathode carbon block in the field of aluminum electrolysis. In production, two ways of calcining coke are usually used in rotary kiln and pot furnace to get calcined petrole...Read more -

Influence of electrode quality on electrode consumption
Resistivity and electrode consumption. The reason is that temperature is one of the main factors affecting the oxidation rate. When the current is the same, the higher the resistivity and the higher the electrode temperature, the faster the oxidation will be. The graphitization degree of electrod...Read more -
How to choose carburizer ?
According to different melting methods, furnace type and melting furnace size, it is also important to select the appropriate carburizer particle size, which can effectively improve the absorption rate and absorption rate of iron liquid to carburizer, avoid the oxidation and burning loss of carb...Read more -
What is the difference between graphite and carbon?
Difference between graphite and carbon among carbon substances is in the way the carbon forms in each matter. Carbon atoms bond in chains and rings. In every carbon substance, a unique formation of carbon can be produced. Carbon produces the softest material (graphite) and the hardest substance ...Read more -
