Product Name: Large Size Graphite Electrode for Silicon metal Making Model NO.: Dia900. Dia960 Forming Way: Molded Graphite Grade: Industrial Grade Carbon Content: High-Carbon Composition: Graphite Type: Graphite Electrodes Trademark: Kingstone Specification: 960, 1146 Origin: China HS Code: 85451900 Product Description Large Size Graphite electrodes are used in submerged arc furnace applications. Submerged arc furnace operations vary slightly from other electric arc furnace applications.A submerged arc furnace is a large furnace loaded with selected and sized raw materials, such as quartz, wood, charcoal, and ores. During the process, these raw materials melt and chemically react. The product that leaves the furnace is a molten metal, such as silicon, ferrosilicon, ferronickel, thermal phosphorus, and zirconium. These molten metals are cooled and further processed into the appropriate size and grade for various applications.Large Size Graphite electrodes are suspended through the furnace roof structure. Carbon electrodes range from 610mm to 1397mm in diameter and can be produced from 2134mm to 2800mm in length. These electrodes are quite dense, weighing up to 6.75mt each.UnitArc Furnace TypeYellow phosphorus HSilicon, SFerroalloy SElectrical Resistivity≤μΩm202020Thermal Expansion Coefficient10-6/°C4.566Ash Content%2.545Break Resistance Intensity≥Mpa666Real Densityg/cm32.02.02.0Bulk Densityg/cm31.581.581.58Flexural strengthMpa4.-7.54.5-7.53.5-7.5Tensile Strength≥Mpa161818Certificate:
