Product Overview
Petroleum coke carburizer is a carbon additive produced from petroleum coke through calcination or graphitization processes, primarily used for carbon content adjustment in foundry and steelmaking applications. Based on processing methods, it can be classified into two main categories: calcined petroleum coke carburizer and graphitized petroleum coke carburizer.
