Needle coke is a premium grade petroleum coke, which is used in manufacturing of graphite electrodes for arc furnaces in steel industry. A good quality of needle coke is hard and dense mass formed with a structure of carbon threads or needles oriented in a
A process is disclosed for manufacturing needle coke, which process involves the steps of comminuting a coal, dispersing it in a suitable solvent, subjecting the dispersion to hydrogenolysis...
Needle cokes are used as a primary material for graphite electrodes in electric furnace. Coal-based needle coke is produced from coal tar that appears during coke production. Compared to petroleum-based needle coke, coal-based needle coke has excellent physical properties, such as low co-efficient of thermal expansion and low electric resistance, along with less spalling and less breakage.
A method for producing needle coke, which comprises recalcining at a temperature of 200 to 1600 ° C. [Effect] Due to the co-carbonization effect of the coal tar heavy oil and the petroleum heavy oil and the synergistic effect of the two-step calcination, an excellent needle coke having an extremely low coefficient of thermal expansion (CTE
