Low-ash synthetic graphite electrode is a graphite electrode made of petroleum coke, coal pitch, and needle coke as raw materials, which are mixed, calcined, impregnated, roasted, graphitized, and finally processed. Through different production and processing techniques, the final ash content of the graphite electrode is less than 0.2%. Low ash synthetic graphite electrode is embodied in RP/HP/UHP. When raw materials are smelted in an electric furnace, the lower the ash and sulfur content of the graphite electrode, the better the quality of the produced product.

Low ash synthetic graphite electrode features
1) Very high electricity load capacity.
2) Bulk density is strictly controlled to have the best thermal shock resistance.
3) Low specific resistance, excellent electrical conductivity, so the energy loss is very small and no electric arc generates at body part.
4) Good high temperature mechanical strength, is not easy to rupture during working.
Production Process
Application of
Application of low Ash Synthetic Graphite Electrode
1. Plant for producing yellow phosphorus
2. Production silicon plant
3. Chromium production plant
4. Smelting and melting scrap at EAF
The low ash synthetic graphite electrode consumed in EAF depends on the steelmaking or other raw materials used, and the grade of steel produced. EAF usually consumes electrodes at a rate of approximately 2 kg per ton of steel produced, while consumption rates for some special steel applications are slightly higher.
