Graphite bundle wheel

Product Introduction: What is a graphite bundle wheel? The graphite bundle wheel, also known as graphite guide wire wheel or graphite hub wheel, is an industrial accessory made from high-purity graphite as the main raw material. It is produced through multiple processes such as isostatic pressing molding, high-temperature sintering, and precise machining. Its core function is to guide, bundle, and transmit materials such as wires and fibers, while reducing friction damage between the materials and the wheel body, ensuring the uniformity and stability of material transmission.

Core Performance: Why Choose Graphite Braided Wheels? Excellent Self-Lubrication: Graphite itself possesses natural self-lubricating properties, with a low friction coefficient. During high-speed operation, no additional lubricants need to be added to achieve smooth contact between the material and the wheel body. This not only reduces the wear of the wheel body and the material but also avoids the contamination of the material by lubricants. It is particularly suitable for the production of products with extremely high cleanliness requirements such as glass fibers and electronic wires. High Temperature Resistance and Thermal Stability: High-quality graphite braided wheels can withstand temperatures above 600°C. Some high-end products can withstand temperatures above 1600°C, and they have a small thermal expansion coefficient, which makes them less likely to deform or crack under sudden heating and cooling conditions, and can stably meet the usage requirements of high-temperature production processes such as metallurgy and glass fiber drawing, ensuring the continuous operation of the production line. Moderate Hardness, Wear Resistance and Material Protection: Graphite braided wheels are precisely sintered and processed to have a hardness of 48-80 Shore A. They can withstand the wear caused by high-speed operation, extend their own service life, and due to their soft texture, they will not cause scratches or damage to the transported wires or fibers, effectively improving the product qualification rate. Some products have undergone surface modification technology, and the wear resistance can be increased by more than 5 times, with a service life extended to over 18 months. Good Chemical Stability and Corrosion Resistance: Graphite materials have excellent chemical inertness and do not react with corrosive substances such as acids, alkalis, and salts. They can operate stably in corrosive environments and are suitable for special production needs in industries such as chemical engineering and new energy. At the same time, the impurity content is strictly controlled to avoid contamination of the materials.

Application industries: Covering multiple fields and suitable for various harsh working conditions. Glass fiber industry: As a key component in the processes of glass fiber drawing, bunching, and winding, graphite bunching wheels are used to guide the transmission and bunching of glass fiber yarns. Their self-lubricating and low-maintenance characteristics can reduce the fiber breakage rate and improve the uniformity of bunching. According to actual cases, after using high-quality graphite bunching wheels, the breakage rate of the production line can be reduced from 1.2% to 0.3%, the product qualification rate can be increased from 92% to 97%, and the annual production cost savings exceed 2 million yuan. It is suitable for various glass fiber production lines, including electronic-grade glass fibers and ordinary glass fibers. Metallurgical industry: Used in metallurgical continuous casting and metal wire drawing processes, it can withstand high-temperature and heavy-load conditions, achieving the guidance and transmission of metal wires, avoiding surface scratches of metal wires, and at the same time, its chemical stability is strong, capable of withstanding corrosive gases in the metallurgical process, reducing equipment wear and extending the production line's service life. In the continuous casting crystallizer guiding system, the graphite bunching wheel can reduce the vibration deviation of the crystallizer from ±0.15mm to ±0.05mm, and the surface defect rate of the cast billet is reduced by 37%. New energy industry: Suitable for the production of components of solar panels, wind power equipment, as well as lithium battery sheet rolling, and new energy wire processing, etc. Its clean, wear-resistant, and high-temperature-resistant characteristics can ensure the production accuracy and quality of new energy products, while reducing pollutant generation and meeting the requirements of green production in the new energy industry. Electronic and precision processing industry: Used for the drawing and guidance of electronic wires, precision metal wires, optical fibers, etc. Its high precision and low friction characteristics can ensure uniform wire diameters and smooth surfaces, avoid wire damage caused by friction, and be suitable for high-end precision production scenarios such as electronic components and optical fiber communication. In the optical fiber drawing tower, the surface roughness of the graphite bunching wheel needs to be lower than Ra0.2μm to ensure the uniformity of the optical fiber diameter.
