High bulk density graphite electrode nipple

DESCRIPTION

Graphite electrodes nipples are used to connect two or more electrodes into column. And the purpose of that is to realize continuous use of electrodes in electric arc furnace steelmaking process. Nipples, with conventional external threads surface, are the important clamping device to extend the electrode length. Doing this avoids the unproductive consumption in smelting.

Graphite Elactrode Nipples FEATURE

Outstanding resistance to breakage

High machining accuracy, good surface finishing

High bulk density, precision thread accuracy

Bending strength limits are measured
