Sinometal Machinery Corp

Sinometal Carbon is one of the leading manufacturer and exporter of Graphite Electrode in China, with total production of 100,000TPA. We are engaging in producing high quality Graphite electrode from D200mm-D700mm (NP, HP, SHP, UHP) used for global metallurgical industry. After years of experience in research and development, we are equipped ourselves with the advanced production, inspection and test equipments, including calcinations, press, baking, pitch impregnation, graphitization, machining, an advanced and complete production process.Our graphite electrodes has the following feature:1. Lower electric resistivity, good electric and heat conductivity;2. High mechanical strength under high temperature;3. High resistance to thermal shock and mechanical vibration;4. Lower ash content;5. According to the customer's feedback information, our electrodes used in EAF/LF with the pretty lower consumption per ton steel.Normal Power Graphite Electrodes (NP)Impregnation Power Graphite Electrodes (IP)High Power Graphite Electrodes (HP)                                 Special Power Graphite Electrodes (SHP)Ultra High Power Graphite Electrodes (UHP)High Density Graphite Electrodes (HD)Supply scope of graphite electrode (in diameter):Ф100mm - Ф700mm  Item Unit Nominal Diameter UHP HP RP Φ300-400 ≥Φ450 Φ250-400 ≥Φ450 Φ250-400 Φ450-600 Electric Resistivity electrode μΩ·m ≤5.0 ≤5.5 ≤6.0 ≤6.5 ≤8.5 ≤9.0 Nipple ≤4.0 ≤4.5 ≤5.5 Transverse Strength electrode MPa ≥15.0 ≥10.5 ≥8.0 ≥7.0 Nipple ≥24.0 ≥20.0 ≥16.0 Young's Modulus  electrode GPa ≤14.0 ≤12.0 ≤9.3 Nipple ≤18.0 ≤16.0 ≤14.0 Bulk Density electrode g/cm3 ≥1.68 ≥1.65 ≥1.54 Nipple ≥1.76 ≥1.74 ≥1.70 Coefficient of thermal expansion electrode 10-6/ºC ≤1.5 ≤2.0 ≤2.5 Nipple ≤1.2 ≤1.6 ≤2.0 Ash % ≤0.2 ≤0.2 ≤0.2
