The carbon electrode production follows similar steps. First, makers collect raw materials like calcined anthracite coal, petroleum coke, and graphite. They crush these materials to make a fine powder.<\/span><\/p>\n<\/h2>\n After that, the powder is mixed with a binder (coal tar pitch) to create a fine mixture. The mixing process binds all the carbon particles together.\u00a0\u00a0<\/span><\/p>\n<\/h2>\n In the next step, this mixture is shaped into electrodes using extrusion. After that, makers bake them at temperatures, ranging between 1000\u00b0C and 1200\u00b0C. The baking makes electrodes hard.<\/span><\/p>\n<\/h2>\n If electrodes have some pores, engineers fill them with a binding material. They do this impregnation in an autoclave.<\/span><\/p>\n<\/h2>\n Like graphite electrodes, these electrodes also undergo a graphitization process. It involves re-baking at a high temperature (about 3000\u00b0C).<\/span><\/p>\n<\/h2>\n At last, makers shape them to achieve specific dimensions depending on their applications.<\/span><\/p>\n<\/h2>\n<\/h3>\n<\/span>Physical & Chemical Properties<\/b><\/span><\/h3>\n<\/h2>\n Graphite Electrode<\/b><\/p>\n<\/h2>\n\nGraphite electrodes are primarily made of natural or synthetic graphite.<\/span><\/li>\n<\/ul>\n<\/h2>\n\nGraphite is an excellent conductor of electricity due to its delocalized electrons that move freely.<\/span><\/li>\n<\/ul>\n<\/h2>\n\nGraphite electrodes offer high thermal conductivity because of their crystalline structure.

Usually, graphite electrode production costs are higher than those of carbon electrodes. Raw materials like needle coke are expensive. Besides this, the overall production of graphite electrodes is complex.\u00a0\u00a0<\/span><\/p>\nCarbon Electrode<\/b><\/p>\n
It is comparatively cheaper to produce carbon electrodes. Its production process does not require graphitization, has low production costs and high economic benefits.<\/span><\/p>\n <\/p>\n
<\/h3>\n<\/span>Service Life<\/b><\/span><\/h3>\nThe service life of electrodes depends on various factors. These include the quality of raw materials, electrode handling, operation, design, and current intensity of electric arc furnaces.\u00a0<\/span><\/p>\nGraphite Electrode<\/b><\/p>\n
In practical applications, the average service life of graphite electrodes is between 50-80 smelting times, and generally needs to be replaced. For large smelting equipment such as blast furnaces, the average service life can reach more than 100 times.<\/p>\n
Carbon Electrode<\/b><\/p>\n
Carbon electrodes have a relatively shorter service life. Their low strength and vulnerability to oxidation make them unsuitable for demanding applications.<\/span><\/p>\n <\/p>\n
