Classification of electrode paste

  The main raw materials for the production of electrodes are anthracite, metallurgical coke, coal and coal pitch, which can be divided into two categories according to different formulations:

  1. Standard and non-standard electrode paste: Standard electrode paste is mainly used in open ferroalloy furnaces and small and medium-sized calcium carbide furnaces, using medium temperature pitch as the binder; non-standard electrode paste is mainly used in large open calcium carbide furnaces, and its dry material particles The composition is the same as the standard electrode paste, but in order to appropriately increase the sintering speed of the electrode paste, a small amount of tar is added to the medium temperature pitch as a binder.

  2. Airtight paste: This type of electrode paste is suitable for airtight chopping ferroalloy furnaces, calcium carbide furnaces and other metallurgical furnaces. The airtight paste uses anthracite as the main raw material. In order to improve the sintering performance of the electrode paste, a small amount of broken graphite and petroleum coke must be added, and a binder with a low softening point must be used.
