Product details
Graphite electrode rods are mainly made of petroleum coke and needle coke as raw materials and coal pitch as binding agent. They are made through calcination, batching, kneading, pressing, roasting, graphitization and machining. They are released in the form of arc in an electric arc furnace. The conductor, which uses electric energy to heat and melt the charge, can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes according to its quality index.
Ordinary power graphite electrode. It is allowed to use graphite electrodes with current density lower than 17A/cm2, which are mainly used in ordinary power electric furnaces for steelmaking, silicon refining, yellow phosphorus refining, etc.
Anti-oxidation coated graphite electrode. The surface of the graphite electrode is coated with an anti-oxidation protective layer to form a protective layer that is both conductive and resistant to high-temperature oxidation, reducing electrode consumption during steelmaking.
High power graphite electrode. It is allowed to use graphite electrodes with a current density of 18-25A/cm2, which are mainly used in high-power electric arc furnaces for steelmaking.
Ultra high power graphite electrode. It is allowed to use graphite electrodes with current density greater than 25A/cm2. Mainly used in ultra-high power steelmaking electric arc furnaces.
Product advantages
01
Excellent conductive properties:
In electrode applications that require conductive current, graphite rods can efficiently transmit electrical energy, ensure the stable flow of current, and ensure the normal operation of related equipment or processes.
Electrons move relatively freely in the graphite structure, allowing the graphite rods to quickly transfer electrons during the electrode reaction, improving the rate and efficiency of the electrochemical reaction.
02
High chemical stability:
Graphite has good chemical stability at room temperature and is resistant to acid, alkali and organic solvent corrosion. In various chemical environments, electrode graphite rods are not easily corroded and damaged and can maintain long-term and stable performance.
Graphite rods can show better anti-oxidation properties and reduce electrode loss caused by oxidation.
03
good lubrication properties：
The lubrication performance of graphite depends on the size of graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubrication performance. In some application scenarios that require relative movement between electrodes and other components, the lubrication properties of graphite rods can reduce friction and wear, improving the service life and operating efficiency of the equipment.
Application areas
Metallurgical industry:
Nonferrous metal smelting: In the process of smelting nonferrous metals such as copper, aluminum, and zinc, graphite electrodes can be used as conductive materials to provide energy for the smelting reaction.
Precious metal smelting: For example, when smelting precious metals such as gold and silver, graphite electrodes can be used in high-temperature smelting and refining processes.
Electric arc furnace steelmaking: This is one of the main application areas of graphite electrodes. When making steel in an electric furnace, graphite electrodes are used to introduce current into the furnace, and an arc is triggered between the electrode end and the charge to produce a high-temperature heat source for smelting.
Electrical industry:
Battery production: It can be used as an electrode material for batteries, especially in new batteries such as lithium-ion batteries. As an anode material, graphite rods have good charge-discharge performance and cycle stability.
Electrical discharge machining: used as a tool electrode for precision machining. Graphite electrode has a high melting point and good electrical conductivity. It can quickly transfer electrons during EDM, causing the metal material on the surface of the workpiece to instantly melt and evaporate, thereby achieving precision machining of the workpiece.
Chemical industry:
Catalyst carrier for chemical reactions: The surface of graphite rods has a certain activity and can support catalysts to promote chemical reactions.
Chemical equipment manufacturing: Graphitized electrodes impregnated with chemical resin or inorganic resin have the characteristics of good corrosion resistance and good thermal conductivity, and can be used to manufacture heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, and cooling towers. heaters, filters, pumps and other equipment.
Sewage treatment: Graphite anode rods can be used as conductive anodes for electrolyzing salt solutions to produce caustic soda, and are also used in sewage treatment in the chemical, electronic, and textile industries.
Machinery industry:
Wear-resistant lubricating material: Graphite material has good lubrication properties and can be used as a lubricant for mechanical parts to reduce friction and wear under high-speed, high-temperature, and high-pressure conditions.
Casting mold and lamination materials: Graphite material has a small linear expansion coefficient and good resistance to rapid cooling and heating. It can be used as a casting mold for glass containers, ferrous metals, rare metals or non-ferrous metals.
