Graphite Elactrode Nipples
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
High Quality graphite electrode nipple SPECIFICATION
