Calcined Petroleum Coke By India Carbon Ltd

we are the largest manufacturer and supplier of Calcined Petroleum Coke in Guwahati, Assam, India. Calcined Petroleum Coke (CPC) is a form of highly electrically conductive, densed Carbon with very low specific Electrical Resistance, and having fixed Carbon of approximately 99.5%.

CPC is used extensively as Anode in Alumina Smelters, as Soderberg's Electrode for Ferroalloy Industries, and in the manufacturing of Graphite/ Graphite Electrodes, and Thermal Paste for Ferro Alloys & allied industries in Submerged Arc Furnaces.

CPC is also used in various Steel Industries for - Melting of Steel , Recurburisation and for making Special Steels & Alloys.

Calcination Process

Raw Coke is Calcined to develop specific properties to make it suitable for industrial purposes. The Calcination (of Raw Coke) involves controlled heating of the Raw Coke to the temperature in the range of 1250C to 1350C. This process drives off moisture, hydrocarbons and other volatile matter present in the Raw Coke is burnt off - thereby densified the particles and changes the electrical properties from insulating to conducting. Raw Coke after Calcination is known as Calcined Petroleum Coke. At India Carbon, Calcination is performed in an oil fired rotary kiln with suitable refractories. Raw Coke crushed into lumps is fed through Conveyor System to the slightly elevated end of the rotary kiln.
