Shida Steel Making Electrodes & Graphite Low Resistivity High Power Needle Coke
400HP Graphite Electrode for Steel Making , in LF , Low Resistivity , Needle Coke
Shida Carbon’s main products are: Dia.450-700mm UHP Graphite Electrode, Isotropic Graphite, 600X800X4400mm Graphite Cathode, high quality Graphite Anode, and Small Medium Grain Size Graphite. Our products are widely used in the industries of electric arc furnace steel making, submerged arc furnace smelting, solar photovoltaics , EDM, fine chemicals, high temperature treatment, precision casting,nuclear power, electrolytic aluminium and etc.
Our new project has created many new records among carbon industry at China and aboard.
- The shortest construction time: 10 months to complete the LWG furnace；
- The highest level of energy saving and environmental protection: By our independent integration and innovation, the car-bottom baking furnace was creatively designed and built with a tail gas incineration and waste-heat power generation system, which effectively solved the pollution problems.
Shida Carbon has been standing nearly thirty years, after the global financial crisis, we have made bold progress against the flow, took the lead in reform and transformation, with the full operation of new production lines and the overall management improving, today Shida has become an international leading high-tech, environment friendly carbon enterprise.
