These conductive media are made of graphite material, and in the process of electric furnace steelmaking, electrical energy needs to be converted into thermal energy to melt steel; Previously, copper electrodes were used as conductive materials, but with the development of technology, graphite electrodes gradually replaced copper electrodes. Inserting graphite electrodes into an electric furnace requires strong high-temperature resistance, which is 3-4 times higher than that of copper electrodes. As the temperature increases, the graphite electrode will gradually melt into the furnace, so it is also a consumable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The principle of graphite electrodes<br><\/h3>\n\n\n\n<p>The principle of using graphite electrodes is to use the electrode end to trigger an arc between the steel material in the furnace, thereby generating high temperature as a heat source to melt the furnace material for steelmaking; Similarly, it can also be used to smelt various other metal raw materials. At present, electric furnace steelmaking is a common steelmaking method that converts electrical energy into thermal energy to generate a heat source, also known as electric arc steelmaking. The principle of graphite electrode is to generate an arc in the electric furnace by discharging between the electrode and the furnace material, causing electrical energy to be converted into thermal energy in the arc light. At the same time, the heating of the arc melts the metal and slag, smelting various components of steel. In addition, there are other steelmaking methods such as induction furnaces and electroslag furnaces.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Use and Performance of Graphite Electrodes<br><\/h3>\n\n\n\n<p>1. Strong conductivity and thermal conductivity;<br><\/p>\n\n\n\n<p>2. High thermal shock resistance and chemical stability;<br><\/p>\n\n\n\n<p>3. Has lubricity and wear resistance;<br><\/p>\n\n\n\n<p>4. Easy to process, with high metal removal rate and low graphite loss during EDM (electric discharge);<br><\/p>\n\n\n\n<p>5. The specific gravity of graphite is 1\/5 of that of copper, and the weight of graphite in the same volume is 5 times lighter than that of copper. The large electrode made of copper is too heavy, which is very detrimental to the spindle accuracy of EDM machine tools during long-term electric discharge. Graphite, on the other hand, does not, and it is also very safe to handle.<br><\/p>\n\n\n\n<p>6. Graphite can have a high processing speed, which is generally 3-5 times faster than ordinary metals. Moreover, selecting tools and graphite with appropriate hardness can reduce tool wear and electrode wear.<br><\/p>\n\n\n\n<p>7. Graphite is easy to shape and does not deform, and some shapes of electrodes are not easy to make with copper, but can be easily achieved with graphite. For example, thin electrode, copper is prone to deformation during machining and EDM, while graphite can easily reach it. Moreover, graphite can use higher current and processing speed during EDM, without worrying about deformation caused by excessive temperature and damage to the workpiece.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Graphite electrode is a graphite based high-temperature resistant conductive material used for electric furnace steelmaking.
