Ordinary Discount 3tpi/4tpi/4tpil Nipple - RP GRAPHITE ELECTRODE – Good Electrical Conductivity, Low Consumption – Aohui Detail:

DESCRIPTION

RP graphite electrodes, referred to moulded columns of graphite, are used as the high temperature conductive material for electric arc furnaces. Regular power graphite electrodes are specified with allowable current density less than 17 A/cm2. The quality of the graphite electrode determines the productivity and cost of EAF steelmaking.

As a manufacturer, we also provide UHP grade graphite electrodes and HP grade graphite electrodes for ultra high power or high power electric arc furnaces. In addition to being used in arc furnaces, graphite electrodes are also widely used in submerged arc furnaces and Ladle furnaces.

FEATURE

High current carrying capacity.
Outstanding resistance to breakage.
High resistance to oxidation and thermal shock.
Good dimension stability, not easy to deform.
High mechanical strength, low electrical resistance.
High machining accuracy, good surface finishing.

APPLICATION

Graphite electrodes are widely used for production of alloy steels, metal and other nonmetallic materials, etc.
