The conductivity of graphite electrode is 100 times higher than that of ordinary non-metallic ore. It is more conductive than steel, iron, lead and other metal materials. The thermal conductivity decreases as the temperature increases. Even at extremely high temperatures, graphite becomes an insulator. Graphite electrode sales, it conducts electricity mainly because each carbon atom in the graphite forms only three covalent bonds with other carbon atoms, and each carbon atom still retains one free electron to transfer charge.
Graphite electrodes has good lubrication performance, its lubrication performance of graphite electrode depends on the size of graphite flake. The larger the flake, the smaller the friction coefficient, and the better the lubrication performance.
Graphite electrode sales market is hot, graphite at room temperature has a good chemical stability, acid resistance, alkali resistance and resistance to organic solvent corrosion. And it is very tough and can be rolled into very thin sheets.
We are the graphite electrode supplier. The graphite electrode is mainly made of petroleum coke and needle coke as raw materials and coal bitumen as binder through calcination, batching, kneading, pressing, roasting, graphenization and machining. It mainly releases electric energy to heat and melt the conductor of charge in electric arc furnace.
Graphite electrodes are machined in cylindrical form and threaded areas are machined at each end. In this way, the graphite electrode can be assembled into the electrode column using the electrode connector. In order to meet the requirements of higher efficiency and lower total cost, high-capacity ultra-high power arc furnace is becoming more and more popular. Therefore, UHP graphite electrode with a diameter of more than 500mm will occupy a dominant position in the market. It is suitable for ultra-high power graphite electrode with high quality needle coke as the main raw material, which is made by molding, roasting, dipping, graphitization and mechanical processing.
Zhengzhou Rongsheng Kiln Refractory Co.,Ltd. Focuses on the production of graphite electrode sales for many years and has a professional technical team, construction team and business team. Welcome to consult and purchase, we will serve you wholeheartedly.
