Graphite Electrodes for silicon

Graphite Electrodes for silicon
Product Detailed
1. Chinese graphite electrodes manufacturer 2. application: for EAF, LF 3. Competitive price 4. Good after-sales service

Artificial graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch. It will experience calcining, burdening, kneading, forming, baking and pressure impregnation, graphitization and then precision machined with professional CNC machining.  such products own characteristics of low resistivity, good electrical conductivity, low ash, high compact structure, good anti-oxidation and high mechanical strength, so it is the best conductive material for electric arc furnace and smelting furnace.

Products Scope:

Regular Power graphite electrode

Impregnated (High density) electrode

High power graphite electrode

Ultra high power graphite electrode

Production Equipment:

2500-ton hydraulic pressing machine, 1700-ton hydraulic pressing machine, 30-room ring type baking furnace, 18-room ring type baking furnace, tunnel kiln, impregnation, 10000kVA DC graphitization furnace, machining, CNC machining, nipple CNC machining

Quality Monitoring Equipment:

Automatic burdening,    analysis for indices of physics and chemistry of product
