What is GPC (Graphitized Petroleum Coke) and what is its use in steelmaking?

GPC or Graphitized Petroleum Coke is a vital material in the steel and ferroalloy industries. In this article, learn about the types of GPC, its properties and applications in the production of graphite electrodes and ferroalloys.

Introduction to GPC (Graphitized Petroleum Coke)

GPC (Graphitized Petroleum Coke) is a product obtained by heating calcined petroleum coke under very high temperatures and then graphitizing. This process increases the carbon purity to more than 98% and creates a dense graphite structure. GPC is a key material in the production of graphite electrodes and ferroalloys due to its high thermal resistance, excellent electrical conductivity and mechanical stability.

Types of GPC based on carbon purity

GPC is usually available in two main types:

GPC with 98% carbon purity – suitable for the production of very high power graphite electrodes and sensitive industrial applications.
GPC with 97% carbon purity – mainly used in the production of ferroalloys such as ferrosilicon, ferromanganese, ferrochrome and ferrosilicomanganese and provides good performance in furnaces.
Application of GPC in steelmaking and ferroalloys

GPC is used as the main raw material in the production of graphite electrodes, electrode paste and carbon additives in electric arc furnaces and ferroalloy furnaces. The use of GPC of the right quality increases furnace efficiency, reduces energy consumption and improves the quality of the final product.

Benefits of Using GPC

Using high-purity GPC has the following benefits:

Very high carbon purity and dense graphite structure
Increase in electrical conductivity and furnace efficiency
Improvement in ferroalloy quality and reduction in impurities
Compatibility with all types of electric arc furnaces and steelmaking processes
