Product Description
High Machinery Strength HP Graphite Electrode Carbon Rod Price
lttrade.en.made-in-china.comA: Company profile
L.T Group has a comprehensive product and technology portfolio that focuses on four fields of graphite - ultrafine particle graphite mould, graphite electrode, graphite crucible, as well as other products mainly made of graphite.
B: Graphite electrode application
Graphite electrode is kind of important conductive material in electric smelting industry, with its specialties: good electrical and thermal conductivity, high machinery strength, anti-oxidant under high temperature, erosion resistance, widely utilized in arc furnace, mineral heating furnace (producing ferroalloy, metal silicon, yellow phosphorus, fused alumina, matte, calcium carbide etc.), resistance furnace (graphitization furnace for producing graphite electrode, melting glass furnace, electric furnace for producing silicon carbide etc.)
All our graphite electrodes are in line with YB/T4088-2015, YB/T4089-2015, YB/T4090-2015 standards.
