Short Description:
Wholesale Price China China Best Graphite Electrodes - RP Graphite electrode – Yidong Detail:
Description
Graphite electrode, mainly using petroleum coke and needle coke as raw materials, coal tar pitch as binding agent, is made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It is released in the form of electric arc in an electric arc furnace. The conductors used for heating and melting the charge by electrical energy can be classified into ordinary power, high power and ultra-high power according to their quality indicators.
We have RP graphite electrodes diameter 100-1272mm.
Application
Graphite electrode is mainly used for metallurgy industry and calcium carbide,phosphor-chemical enterprise,such as iron and steel smelting,industrial silicon,yellow phosphorous,ferroalloy,titania slag,brown fused alumina etc submerged-arc furnace melting production.
Specification
The physical and chemical indexes of common graphite electrodes and joints refer to YB/T 4088-2015
