graphite electrode UHP300mm

Ultra-high power graphite electrode (UHP) is a type of graphite electrode and is a high-value-added product. The following is a detailed explanation of the ultra-high power graphite electrode:

I. Definitions and Characteristics

Ultra-high power graphite electrodes are a kind of high-temperature resistant graphite conductive material produced through a series of processes including calcination, crushing and grinding, batching and kneading, extrusion molding, roasting, asphalt impregnation, graphitization and mechanical processing, with petroleum coke and needle coke as the main raw materials and coal tar pitch as the binder. Its main feature is that it has higher electrical conductivity and better thermal stability than graphite electrodes RP and HP, and can withstand high-temperature and high-pressure environments, ensuring the stability and efficiency of the smelting process.

Ii. Specifications and Classification

Ultra-high power graphite electrodes can be classified into various specifications based on their diameters and lengths, such as 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm, 650mm and 700mm. The lengths are available in combinations such as 1600mm, 1800mm, 2000mm, 2200mm and 2400mm. These specifications of graphite electrodes can meet the requirements of different smelting equipment and processes.

Iii. Application Fields

Ultra-high power graphite electrodes are mainly applied in the electric arc furnace smelting process, especially playing a significant role in the smelting of industries such as steel and non-ferrous metals. In addition, it can also be used to manufacture various high-temperature and high-pressure reactors, such as in the production processes of chemical raw materials like ammonia synthesis and hydrocyanic acid. In the mechanical manufacturing industry, ultra-high power graphite electrodes are also used to manufacture various high-temperature and high-pressure equipment, such as in heat treatment, welding and other fields.

Iv. Production Technology and Process

The production process of ultra-high power graphite electrodes involves multiple steps such as raw material preparation, batching and kneading, extrusion forming, calcination, asphalt impregnation, graphitization and mechanical processing. Among them, graphitization is one of the key steps in the production process of ultra-high power graphite electrodes, which determines the electrical conductivity and thermal stability of the electrodes.

V. Development Trends

With the rapid development of the new energy and environmental protection industries, the demand for ultra-high power graphite electrodes is also constantly increasing. In the future, the production technology of ultra-high power graphite electrodes will continue to be improved and innovated to enhance their performance and quality and meet a wider range of application requirements. Meanwhile, environmental protection and sustainable development will also become important directions for the production of ultra-high power graphite electrodes.
