The Manufacturing Process of Graphite Electrodes

STEP 2:

Baking Process

To carbonize the pitch, it is subjected to heat treatments of approximately °C.
If baking process is carried out in a short time, cracks and pores could occur due to volatile substances included in the pitch or shrinkage. Because of that, a controlled baking and cooling process is carried out over a duration of approximately one month.
