Product Details
Product Introduction
Our company specializes in the production of high-quality, high-power graphite electrodes. We utilize a blend of premium domestic petroleum coke and imported needle coke, manufactured through precision molding, high-temperature roasting, and graphitization. Our products exhibit low resistivity, excellent thermal and electrical conductivity, and exceptional thermal shock and oxidation resistance, as well as mechanical strength. They are widely used in electric arc furnaces (EAFs), refining furnaces (LFs), and submerged arc furnaces (SAFs) for the smelting of alloy steel, stainless steel, and non-ferrous metals. We offer a variety of specifications and models, including conventional, high, and ultra-high power, to meet diverse customer requirements for size, purity, and performance. As an export-oriented enterprise, our products are exported to Europe, America, Southeast Asia, the Middle East, and other regions. These products comply with international metallurgical industry standards, making us a trusted, long-term partner for global steel manufacturers.
Advantages and features
1. Adopting a composite formula of imported needle coke + domestic petroleum coke to ensure a dense electrode structure and stable performance;
2. The graphitization temperature is as high as 2800℃, which significantly reduces the resistivity and improves energy efficiency;
3. Strong thermal shock resistance, able to maintain structural integrity under frequent start-stop conditions;
4. High surface finish, reducing arc blow phenomenon and extending service life;
5. Supports customization of diameter, length and grade according to customer needs, and flexibly adapts to various furnace types.
Application Scenario
Suitable for international steel mills, alloy steel mills, ferroalloy production enterprises, and non-ferrous metal smelting units, it is particularly suitable for modern metallurgical projects that pursue high energy efficiency, long life, and low-cost operation. Key markets include Europe, North America, Southeast Asia, the Middle East, and South America.
