What is needle coke and graphite electrode?<\/h3>\n

Needle coke is a silvery white solid carbon material with metallic luster. Obviously, under the microscope, it shows a needle-like texture and is used widely in high-performance graphite electrode materials. Based on the different raw materials used, needle coke can be divided into two types: oil-based and coal-based. The former is produced with petroleum residue as the raw material while coal-based needle coke is made with coal tar pitch and its fractions as the raw material.<\/p>\n

Graphite electrodes are made from graphite, organic binder. The function is to conduct the electrical energy from the power source into the molten steel in an electric arc furnace.<\/p>\n

              Industrial and Sustainable Benefits<\/b><\/strong><\/p>\n

              Grafito<\/a> is helpful to a large extent and reduces the cost of production of steel with such volatile prices. For several industrial applications, Electrodos de grafito<\/a> are economic and quite reliable. Again, with such challenges of sustainable manufacturing and stating the ideal choice of material for industries nowadays, it is good news to hear.<\/p>\n

              Application of needle coke graphite electrode<\/h2>\n

              Steelmaking and Metallurgy<\/b><\/strong><\/p>\n

              Needle Coke Electrodes Electrodes are an indispensable part in all applications related to high temperature and energy. In an Electrical Arc Furnace meant for making steel, electrodes conduct a very high current. These provide the required quantity of heat to melt scrap steel and iron. Such kinds of electrodes are in much-needed for Ultra High Power Operations in the Metallurgical Industry. They have high carrying capacity with low consumptions under extreme conditions.<\/p>\n

               <\/p>\n

              Various Industrial applications<\/b><\/strong><\/p>\n

              These electrodes play an important role in the manufacture of lithium-ion battery anodes, too, since their high purity and high conductivity give a true boost to battery performance. In the petrochemical and chemical industries, such electrodes are indispensable for certain processes-for example, production in silicon and phosphorus industries. Besides, nonferrous smelting -industries of aluminum and magnesium, for instance-can be based only on these electrodes. Their properties being superior in this regard assure efficiency, durability, and reliability in those fields.<\/p>\n

              How to Make Needle Coke Graphite Electrode ?<\/h2>\n
                \n
              1. Selection of Raw Material and Production of Needle Coke<\/b><\/strong><\/li>\n<\/ol>\n

                Needle coke<\/a> is a major aggregate for graphite electrodes that are usually made from heavy petroleum-based oils or coal tar pitch. During the production, CTE of needle coke is controlled so that the consumption of electrodes during steel making is minimum.<\/p>\n

                  \n
                1. Mixing and Forming<\/b><\/strong><\/li>\n<\/ol>\n

                  The needle coke particles are mixed with binder pitch in the appropriate proportions and then heated, kneaded, and extruded or pressed into the desired electrode shape to produce a “green electrode.”<\/p>\n

                    \n
                  1. Calcination<\/b><\/strong><\/li>\n<\/ol>\n

                    Calcination of the green electrode is effected through heating at controlled temperature with the aim of carbonizaci\u00f3n<\/a> of the material. Thus, volatile matter content becomes reduced and structural integrity gets improved.<\/p>\n

                      \n
                    1. Grafitizaci\u00f3n<\/b><\/strong><\/li>\n<\/ol>\n

                      Next, the calcined electrode undergoes graphitization heat treatment in ovens with high temperatures above 2500\u00b0C. This reduces the carbon into crystalline graphite, which is vital in enhancing thermal and electrical conductivity.<\/p>\n

                        \n
                      1. Processing<\/b><\/strong><\/li>\n<\/ol>\n

                        The final graphite electrode processing to exact dimensions ensures the equipment of EAF and thus performance during the steel-making process.<\/p>\n

                          \n
                        1. CTE Control Technology<\/b><\/strong><\/li>\n<\/ol>\n

                          Among the critical reasons for graphite electrode durability and cost-effectiveness, the coefficient of thermal expansion factor takes the lead. In this respect, it is kept at a fast pyrolysis temperature above 750\u00b0C with less than a 5-second residence time to make it result in a low CTE needle coke. As for the CTE, the smaller value, better the needle coke against heating.<\/p>\n

                          Why buy our graphite electrode needle coke?<\/h2>\n

                          Our needle coke graphite electrodes boast a high level of conductivity and are very durable; thus, their wear-off consumption rate is small. Its resistance to thermal shock and oxidation makes these materials assure efficiency in various steel processes, battery manufacturing, or non-ferrous melting.<\/p>","protected":false},"excerpt":{"rendered":"
