1.Product Introduction
Graphite rod is a non-metallic material made of graphite as the base material, after adding a binder, it is extruded and baked at high temperature. This material is widely used in many fields due to its high temperature resistance, good conductivity and high mechanical strength. The following will discuss the main uses and characteristics of graphite rods:
(1) Manufacturing and processing
Manufacturing process: The production process of graphite rods includes steps such as mixing, extrusion and high temperature baking. It is baked at a high temperature of 2200℃ and coated with a layer of copper to improve its conductivity and oxidation resistance.
Physical properties: Graphite rods have excellent high temperature resistance and can withstand temperatures up to 3000℃. It has high thermal conductivity and a resistivity between 8 and 13×10^-6 Ω·m, which makes graphite rods outstanding in electric heating elements.
(2) Industrial application
Metal cutting: Graphite rods are often used as cutting consumables before welding, used in carbon arc gouging cutting process, and are suitable for cutting metal into shapes that meet the requirements.
Smelting tools: In the process of metal smelting, graphite rods are used as electric heating bodies in high-temperature vacuum furnaces due to their high-temperature resistance. Especially in the smelting process of platinum and gold, graphite rods show excellent anti-oxidation and low resistance properties.
(3) Electrical applications
Electrode materials: Due to the good conductivity of graphite rods, they are used as electrode materials for electric furnaces, especially in the smelting process of making various alloy steels and ferroalloys.
Battery materials: Graphite rods also play a role in making certain types of batteries, especially when high conductivity is required.
(4) Corrosion-resistant applications
Chemical equipment: Graphite rods can be used to make equipment parts that can work stably in extreme chemical environments, such as reactors and heat exchangers.
Marine engineering: In marine engineering, graphite rods are used to build equipment resistant to seawater corrosion due to their corrosion resistance.
(5) Thermal stability
High temperature stability: Graphite rods can still maintain stable physical and chemical properties in high temperature environments, and are suitable for continuous operation at high temperatures.
Small thermal expansion coefficient: The thermal expansion coefficient of graphite rods is small, which makes them stable when the temperature changes, avoiding the problem of dimensional instability caused by temperature changes.
In addition, with the development of science and technology, the application scope and technology of graphite rods are constantly improving. For example, in the high-tech field, graphite rods can be used to manufacture high-precision equipment parts. At the same time, the performance of graphite rods is also being studied to meet the possibility of wider industrial needs.
In short, graphite rods not only play a key role in traditional high-temperature and conductive applications, but their potential applications in emerging technology fields are also being developed. For engineers and researchers, understanding the characteristics of graphite rods and their most suitable working environment is the key to designing and maintaining efficient systems.
