Production Process
As a leanding manufacturer of Graphite Electrodes in China, HAIHAN holds complete productionlines, from the Petro Coke calclining to the Machining, therein, Ring Pit Baking Furnaces, High Pressure Impregnation Vessels, DC Graphitization Furnaces, Lengthwise Graphiteization Fruances, and Numerical Contro Lathe Machining Line, etc. all reach international advance level.
Forming
Storage & Transportation
What matters should be paid attention to in the storage of graphite electrodes in steel mills?
1. Place the graphite electrode on a wooden or iron frame.
2. Do not unpack the unused electrodes.
3. The damp electrode should be dried before use.

Quality Inspection
“Quality Oriented, Credit Supremacy” is always our business principle, we obtained ISO9001 Certification for Quality Management System, ISO14001 Certificateion for Enviroment Management System and OSHAS 18001 Certification for the Health and Safety System, with our own perfect technology development and advanced quality inspection system, the quality of our products have reached international standard, and we have 20-30 years experienced technical personnel for our all-around pre-sales, mid-sales and after-sales service.
For the performance of the finished electrode: check the product accuracy, weight, length, diameter, bulk density, resistivity, pre-installation accuracy, etc.
For the appearance inspection of graphite electrodes: no black skin, no cracks, and no honeycomb on the electrode surface,draw the safety line at the bottom of the hole.
