Petroleum coke must be calcined to meet the requirements of industrial production. The calcination temperature is usually around 1300°C. The purpose is to remove the volatiles in petroleum coke as much as possible.
It greatly reduces the hydrogen content of calcined petroleum coke and improves the degree of graphitization. As a result, the high-temperature strength and heat resistance of the graphite electrode are improved, and the conductivity of the graphite electrode is improved.
