The introduction of High power graphite electrode

Description:
Graphite electrodes are an important electric admixture industry conductive actual with acceptable electrical conductivity, thermal conductivity, top automated strength, top temperature and acceptable bane attrition to blaze is broadly acclimated in electric arc animate furnaces, ore admixture electric boiler (production of ferroalloy, authentic silicon, Yellow, Matte, calcium carbide, etc.), attrition boiler (such as assembly of graphite electrodes graphite furnace, bottle melting furnace, electric boiler assembly of silicon carbide, etc.), has become a avant-garde automated raw materials, an important part.
High power graphite electrode
High power graphite electrode are bogus with 100% petroleum aggravate cokes according to the Ultra-high ability graphite electrodes advantageous technology through the action of crushing, screening, dosing, kneading, extruding, baking, top impregnation, rebaking, graphitizing, machining etc. And nipples are bogus with 100% petroleum aggravate cokes alien from Japan, according to the technology of leash assimilation and quadruple baking.
