Graphitized Recarburizer
Graphitized carburizer is a product used for carbon addition in the steelmaking and casting industries, prepared from petroleum coke through high-temperature graphitization treatment. Graphitized carburizer is also suitable for raw materials requiring high carbon and sulfur content for producing carbon or graphite products.
