Main use

 Electric arc furnace steelmaking, industrial silicon furnace, phosphorus furnace, corundum furnace

 My nearly 30% of graphite electrodes for export, domestic demand was mainly concentrated in the electric arc furnace steel (35%), submerged arc furnace smelting yellow phosphorus (9%), abrasive (8%) and silicon (5%) 4 industry, other industries minimal requirements.

 Allows the use of current density of 18 ~ 25A/cm2 of graphite electrodes, mainly for high-power electric arc furnace steelmaking.

 Product testing

 Electrode quality inspection carried out by the Carbon carbon QC, customers in accordance with the provisions of the standard acceptance.

 Packaging

 Graphite electrode with wooden boxes, wooden frame at the end of care packages, and difficulties with the packing strip bar.

 Logo

 Finished electrode in the connector hole at the end of the corresponding safety line marked on the electrode surface.
