1. Phosphorus Furnace UHP graphite Electrode 600mm
2. Low sulfur electrode for yellow phosphorus production
3. Custom threaded electrode for submerged arc furnace
Product Description:
Graphite electrode is made of high-quality calcined petroleum coke, imported needle coke and modified coal asphalt,the grade are RP,HD(impregnation),HP and UHP graphite electrodes,the specification is Ø75-700mm.
Graphite electrode produced by our company has the advantages of low resistivity,high electrical conductivity and thermal conductivity,good oxidation resistance,good thermal shock resistance,high mechanical strength,easy to machine,etc.
Graphite electrodes are widely used to smelt steel, alloy steel, and other metal or non-metal materials in electric arc furnaces.
The size of the graphite electrode used in the Phosphorus Furnace needs to be determined according to the furnace type, power, and production process. The following are industry standards and selection recommendations:
| Furnace Capacity | Recommended Graphite electrode Diameter (mm) | Current Density (A/cm3) | Jointed way |
| Small (≤5000 ton/year) | 250-350 | 15-20 | NPT |
| Medium(5000-20,000 ton/year) | 400-500 | 12-18 | PIN |
| Big (≥ 20，000 ton/year) | 550-700 | 10-15 | Composite-Jointed |
Note: 1. Ultra-High Power Graphite electrode is more suitable (Electrical resistance ≤ 5.5μΩ·m), reducing energy consumption.
2. Low sulfur content（ S< 0.5%）， Avoid contamination from phosphorus products.
3. Length of the Graphite electrode Standard: 1800-2400mm( Easy to install on the furnace Top)
