METHOD FOR MAKING GRAPHITE ELECTRODES

摘要

In a method for baking green graphite electrodes in which the green electrodes are supported in a sagger can with graphite particles. In one method, the amorphous graphite is used to line the bottom of the sagger underneath the green electrodes, while the remainder of the sagger is filled with standard sized petroleum coke. In a second method, the green electrodes are completely supported within the sagger with amorphous graphite. In the preferred method, the graphite is sized between 30 and 6 mesh (U.S.) and is generally greater than 70 % carbon.
