Recarburizer / Carbon Raiser

Graphitized Pteroleum Coke (GPC) :

High purity graphitized petroleum coke is made from high quality peroleum coke under a temperature of 2,500-3,500C. 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 to produce high quality steel, cast iron and alloy. It can also be used in plastic and rubber as an additive.

Application :

It can be used as carbon raiser (Recarburizer) to produce high quality steel, cast iron and alloy. It can also be used in plastic and rubber as an additive.

Calcined Petroleum Coke(CPC):

Calcined Petroleum Coke (CPC) is manufactured from Raw Petroleum Coke (RPC) by the process known as high temperature pyrolysis. The process is carried out in a rotary or vertical kiln at temperatures exceeding 1300 deg C. Calcination of CPC is essentially a high temperature treatment in which the carbon to hydrogen ratio of RPC is increased from 20 to 1000 and above. Calcination is achieved by complete demoisturisation and dehydrogenation of RPC under controlled conditions. During the process molecular rearrangement takes place making the CPC electrically conductive, an essential property required for Aluminium smelting.

We have a modern and automated production facility of manufacturing Carbon Products, The setup gives us the ability to execute both large and small orders of Carbon Products. Meticulously maintained, our manufacturing unit is marked by industry defined safety and quality certifications, which assures consistent quality and reliability.

We also have reliable facilities for quality testing, packaging and logistics to ensure that you can depend on us for your supplies. Using the best of machines and through the employment of a trained and skilled labour force, we are able to achieve excellent production levels.
Calcined Petroleum Coke

Manufacturing Process OF CPC :

Calcination is a high temperature process for transforming the physical properties of raw petroleum coke. Sized petroleum coke is stored in silos and fed into a rotary kiln in controlled ratios. The calcination process raises the material temperatures in the kiln to around 1200 to 1260°C depending on the quality of raw cokes and specification of C P Coke desired.

The material flows in a counter direction to the temperature controlled hot gases fired from a kiln burner. During the radiation heat transfer process, the material comes across various reactive zones where it de-moisturises, devolatalises and stabilizes with improved crystalline structure. Operating parameters are controlled to impart the required crystal structure, density and electrical conductivity.

The calcined coke is first cooled by water quenching the red-hot material, and then further cooled by natural draft air as it tumbles through the length of the cooler, on its way to the conveyors leading to storage in the godowns.
