700mm Graphite Electrode Advantages<\/h2>\n

High Conductivity<\/b><\/strong><\/p>\n

The 700mm graphite electrode possesses exceptionally high conductivity, which is suitable for high-energy applications, such as electric arc furnaces and refining furnaces<\/a>. It efficiently conducts large currents, supporting rapid and continuous high-temperature smelting processes.<\/p>\n

High-Temperature Resistance<\/b><\/strong><\/p>\n

Even in intense heat exceeding 3000\u00b0C, the graphite electrode remains stable without significant deformation or wear. This property is especially critical for high-temperature smelting applications.<\/p>\n

Mechanical Strength<\/b><\/strong><\/p>\n

The 700mm graphite electrode has adequate mechanical strength to operate stably under high-temperature and high-pressure conditions. Its robust structure not only extends the electrode’s lifespan but also reduces the costs and time associated with frequent options.<\/p>\n

Thermal Shock Resistance<\/b><\/strong><\/p>\n

With excellent resistance to thermal shock, the graphite electrode can adapt to rapid temperature fluctuations so as to minimize the risk of cracking or damage. This characteristic is particularly essential in applications that require repeated heating and cooling.<\/p>\n

Oxidation Resistance<\/b><\/strong><\/p>\n

The graphite electrode shows strong oxidation resistance in high-temperature environments, effectively resisting oxidative reactions. This quality helps reduce electrode consumption and extends its service life.<\/p>\n

Chemical Stability<\/b><\/strong><\/p>\n

In harsh chemical environments, the graphite electrode maintains chemical stability. This property ensures that the electrode does not introduce impurities during the smelting process, and this enhances the purity and stability of the smelted materials.<\/p>\n

 <\/p>\n

Manufacturing Process of Graphite Electrodes<\/h2>\n

Main Raw Materials<\/h3>\n

Petroleum Coke:<\/b><\/strong><\/p>\n

Low-ash carbon materials with great purity and outstanding conductivity abound here. Reduced impurities generated during the smelting process by low ash concentration helps to improve electrode purity and increase stability at high temperatures.<\/p>\n

Needle Coke:<\/b><\/strong><\/p>\n

The special\u00a0structure of needle coke improves the mechanical strength and conductivity of the electrode<\/a>. Although needle coke strengthens the structure of the electrode and provides stability under high current density circumstances, it reduces the likelihood of rupture under high temperatures and strong currents.<\/p>\n

Coal Tar Pitch: <\/b><\/strong><\/p>\n

Coal tar pitch tightly bonds petroleum coke and needle coke as a \u201cbinder\u201d to guarantee a small electrode structure during the manufacturing process. This substance not only improves the resistance of the electrode to thermal shock and durability but also during shaping.<\/p>\n

 <\/p>\n

Production Process<\/h3>\n

Baking:<\/strong><\/p>\n

During the baking process, the raw materials are heated\u00a0in a high-temperature environment to\u00a0incrementally\u00a0remove moisture and impurities. Baking not only purifies the materials but also significantly enhances the electrode\u2019s heat resistance, enabling it to remain stable in high-temperature smelting processes.<\/p>\n

Graphitization:<\/strong><\/p>\n

This is a critical high-temperature treatment step. The carbon structure of the raw materials is further changed into a graphite structure by heating them to 3000\u00b0C, only in that way can it enhance\u00a0the conductivity of the electrode and enable\u00a0it to manage large current densities.<\/p>\n

Shaping and Machining:<\/strong><\/p>\n

The materials are subsequently worked upon following graphitization to satisfy certain form and size criteria. The form and surface of the electrode are precisely tuned at this step to guarantee fit with several equipment in diverse uses.<\/p>","protected":false},"excerpt":{"rendered":"

700mm graphite electrode ultra-high power is used in scrap preheating electric arc furnace (eaf), equipped with a rated capacity of 160000KVA transformer. This process is to smelt steel scrap in a 120-ton electric arc furnace and use it with a refining furnace to smelt steel. The refining furnace also uses ultra-high power graphite electrodes with smaller specifications. At the same time, it is equipped with nipples to connect the electrodes. Our 700mm graphite electrodes are able to carry a larger current density. They are also used in the electric arc furnace smelting process of non-ferrous metals such as metallic silicon, copper and aluminum.<\/p>","protected":false},"featured_media":6618,"template":"","meta":[],"product_brand":[],"product_cat":[37],"product_tag":[],"class_list":{"0":"post-6615","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-graphite-electrode","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"yoast_head":"\n700mm
