Product Features
The high-purity graphite sheets from Harog Technology are characterized by the following excellent features:
- High Purity: With a purity of over 99.9%, they maintain stable performance in high-temperature and corrosive environments, without introducing impurities that could affect the quality of non-ferrous metals.
- uperior Electrical and Thermal Conductivity: Their electrical conductivity is 1/5-1/2 that of copper, and their thermal conductivity is better than that of many metal materials. This enables them to quickly and evenly conduct heat and electricity, meeting the strict requirements for temperature and current control in the non-ferrous metal smelting process.
- High-Temperature Resistance: Graphite has a melting point of 3850±50℃ and a boiling point of 4250℃. Even when subjected to ultra-high-temperature electric arc burning, the weight loss is minimal, and the thermal expansion coefficient is also very small. They can withstand the high-temperature environment in non-ferrous metal smelting.
- High Chemical Stability: They have good chemical stability at room temperature and can resist the corrosion of acids, alkalis, and organic solvents, making them suitable for various non-ferrous metal smelting processes.
- Self-Lubrication: The lubricating properties of graphite depend on the size of the graphite flakes. The larger the flakes, the lower the friction coefficient and the better the lubricating performance, which helps to reduce equipment wear.
- Ease of Processing: Compared with metal materials, they have a lower volume density, thus achieving lightweight design. Moreover, they have excellent mechanical processing properties, which are conducive to precise shaping.
Application Fields
The high-purity graphite sheets from Harog Technology play a vital role in non-ferrous metal smelting:
- Manufacturing Refractory Materials: They are used to make graphite crucibles, furnace lining materials, etc. These materials can withstand the high-temperature smelting process without easily melting or deforming. Meanwhile, their chemical stability ensures the purity and quality of metals.
- Electrode Materials: In the electrolytic smelting of non-ferrous metals, high-purity graphite electrodes can withstand high current densities. Their chemical stability also ensures the service life of electrodes during the electrolytic process.
- Mold Manufacturing: They can be used to manufacture various molds for non-ferrous metal smelting, such as continuous casting molds and sintering molds, to ensure the forming quality and dimensional accuracy of metals.
- Other Applications: They can also be used to manufacture components for degassing systems and insulating materials, reducing heat loss and improving smelting efficiency.
