Graphite electrodes dia 75

Graphitized electrodes EG/RP with a diameter of 75 mm and nipples for them are made on the basis of petroleum and needle cokes and coal tar pitches. These products are used in arc steelmaking furnaces, refining, ferroalloy furnaces, ore thermal and other electrical installations.

The technology for manufacturing graphite electrodes includes the preparation of raw materials - crushing and calcination, mixing fillers with pitch and molding, firing, impregnation, graphitization and mechanical processing. For the production of pressed blanks, extrusion and vibration molding methods are used.

Electrodes with a diameter of 75 mm are available in lengths from 1200 to 1800 mm. There are sockets at both ends of the electrode with cylindrical thread for screwing in the nipple. The nipple is necessary for extending the electrode as it is consumed during the steelmaking process.

Each electrode is equipped with a nipple. At customer's request, nipples can be supplied separately from electrodes or in addition to the kit.
