2023-10-11The graphite column combines the wear resistance of copper alloy and the self-lubricating performance of solid graphite lubricant, making it unnecessary to refuel and maintain during use. The product is widely used for high load, intermittent or swinging movements, such as production lines for steam locomotives, water turbines, reservoir work/accident doors, plastic machinery, etc. According to the operating conditions used, various types of copper alloys can be provided.The main component of graphite column is graphite, and its performance is different from that of ordinary graphite1、 The production and processing technology characteristics of graphite pillars:1. High temperature resistance: Graphite is currently one of the most high-temperature resistant materials known. Its melting point is 3850 ℃± 50 ℃, and its boiling point reaches 4250 ℃. It is subjected to an ultra-high temperature arc at 7000 ℃ for 10 seconds, with the smallest loss of graphite, which is 0.8% by weight. From t

2023-10-101. Used as refractory material: Graphite and its products have properties of high temperature resistance and strength, and are mainly used in the metallurgical industry to manufacture graphite crucibles. In steelmaking, graphite is commonly used as a protective agent for steel ingots and as a lining for metallurgical furnaces.2. As a conductive material: used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, positive electrodes for mercury positive current transformers, graphite gaskets, telephone parts, coatings for television tubes, etc.3. As a wear-resistant lubricating material: Graphite is often used as a lubricant in the mechanical industry. Lubricating oil often cannot be used under high-speed, high-temperature, and high-pressure conditions, while graphite wear-resistant materials can work without lubricating oil at high sliding speeds at temperatures of 200-2000 ℃. Many devices that transport corrosive media are widely made of graphite m
2023-10-091. Good wear resistance, low friction coefficient, and long service life.2. Having an appropriate amount of elasticity and plasticity can distribute stress over a wider contact surface, improving the bearing capacity.3. It can reduce vibration, reduce noise, prevent pollution, and improve labor conditions for machinery.4. During operation, a transfer film can be formed to protect the grinding shaft without any biting phenomenon.5. The hardness requirements for grinding shafts are low, and shafts that have not been quenched and tempered can be used, thereby reducing the difficulty of machining related parts.6. Thin walled structure, lightweight, can reduce mechanical volume.7. At present, it has been widely used in various sliding parts of machinery, such as printing machines, textile machines, tobacco machinery, micro motors, automobiles, motorcycles, and agricultural and forestry machinery.
2023-10-09Carbon blocks made from high-quality anthracite, coke, graphite, etc. Used as a cathode for aluminum electrolysis cells. It is built at the bottom of the electrolytic cell, also known as the bottom carbon block. The characteristic cathode carbon block plays a dual role in conducting electricity and forming the inner lining of the electrolytic cell. Aluminum electrolysis production requires cathode carbon blocks to have high temperature resistance. The characteristics of resistance to molten salt erosion and conductivity, good thermal conductivity, high mechanical strength, good thermal shock resistance, and strong sodium corrosion resistance are conducive to energy conservation and improved cell life in aluminum electrolysis production.Graphite cathode is a conductive material used for the cathode of aluminum electrolysis cells, representing the development direction of the electrolytic aluminum industry. With the technological progress and development of the electrolytic aluminum ind
