<\/p>\nUHP graphite electrode is mainly used for smelting scrap steel in eaf steelmaking production. As a high-temperature resistant conductor, it can easily melt various high-melting-point alloys in the arc temperature zone (up to 3000-6000 \u00b0C\u00a0) in the electric arc furnace connected to a three-phase transformer.<\/p>\n
UHP graphite electrodes can also be used in ladle refining furnaces, continuous casting and other processes. The purpose of refining is to improve the quality of steel. This process uses the arc generated between the electrode and the molten steel to heat the electric arc furnace steelmaking. This will help steel mills achieve high production, high quality and low consumption.<\/p>\n

Even in harsh high temperatures up to 3600 degrees Celsius, it will not melt or deform or be damaged under the action of strong arcs.<\/p>\n Low specific resistance:<\/strong> The specific resistance of the electrode body is below 5.0g\u2215\u339d3<\/sup>, and the nipple is below 4.0g\u2215\u339d3<\/sup>. At this time, the resistance to current is small, reducing power loss.<\/p>\n High density:<\/strong> The overall structure has smaller porosity, reducing electrode consumption.<\/p>\n Good electrical conductivity:<\/strong> They have low ash content, are heat-resistant and corrosion-resistant. Therefore they are excellent conductive materials used in electric arc furnaces at high temperatures.<\/p>\n High mechanical strength:<\/strong> During the kneading process, the coke particles are mixed evenly and bonded firmly. Therefore, the flexural and compressive strength are high.<\/p>\n Small thermal expansion coefficient:<\/strong> Because needle coke is added during the production process, the blank is more easily graphitized at high temperatures above 2000\u2103. The better the degree of graphitization, the smaller the thermal expansion coefficient.<\/p>\n The resistivity of UHP graphite electrode is the lowest among all electrode types. This means that it can pass higher density current without breaking or deforming during arc furnace smelting.<\/p>\n Jinsun uses needle coke<\/a> in production to enhance the thermal shock resistance of the electrode<\/a> itself. This makes it have a lower thermal expansion coefficient and can better resist rapid changes in temperature without being damaged.<\/p>\n The density of the double-impregnated UHP graphite electrode has been greatly improved. So, even at high temperatures, it oxidizes slowly, reducing the number of replacements.<\/p>\n Its diameter can be more than 750mm, which can meet the smelting needs of 100MT ultra-high power arc furnaces.<\/p>\n <\/p>\n It is important to note that the price of it may vary due to market conditions, supply and demand dynamics, and other external factors. In addition, the rising cost of raw materials such as needle coke has also driven the price.<\/p>\n As a graphite electrode producer in China, Jinsun has a complete production line, including raw material mixing, roasting, impregnation, graphitization, processing, etc. Our factory manufacture and supply high quality UHP grade graphite electrodes for your EAF steelmaking production.<\/p>\n <\/p>\n \u2264<\/strong><\/td>\n \u2265<\/strong><\/td>\n \u2264<\/strong><\/td>\n \u2265<\/strong><\/td>\n \uff08100\uff5e600\u2103\uff09<\/td>\n \u2264<\/strong><\/td>\n <\/p>\n Capacity\uff08A\uff09<\/td>\n \uff08A\/cm2<\/sup>\uff09<\/td>\n<\/tr>\n <\/p>\n Generally speaking, there are three types of graphite electrodes according to different powers, namely, UHP, HP, and RP. However, some manufacturers will produce SHP graphite electrodes. This grade of electrode is between HP and UHP grades, and its price is relatively low.<\/p>\n <\/p>","protected":false},"excerpt":{"rendered":" UHP graphite electrodes are used for electric arc furnace and high-load ladle furnaces.
