Varieties and uses of carbon rods

Time：2023.08.08Browse：1: Share:

Carbon rods are made from carbon or graphite materials as the substrate. Carbon rods can be used as electrodes for arc discharge in various electrical equipment that generate thermal or light energy. During arc discharge, high temperature and strong luminous intensity are generated.

Carbon rods can be divided into film projection carbon rods, high color temperature photography carbon rods, ultraviolet linear and sunlight type carbon rods, photographic plate making carbon rods, carbon arc air gouging carbon rods, precision casting carbon rods, electrolytic carbon rods, arc lighting carbon rods, spectral carbon rods, battery carbon rods, and welding carbon rods according to their purposes.

Arc lighting carbon rods are used in searchlights, as well as in strong arc lamps for film projection, photography, plate making, and ultraviolet light sources. Carbon arc air gouging carbon rods are used for arc cutting of metal materials, drilling, eliminating casting risers and other defects. Spectral carbon rods are used for emission spectrographs, welding carbon rods are used as electrodes for arc welding, and electrolytic carbon rods are used for electrolysis of molten metal salts or solutions. In addition, there are graphite tubes used for graphite furnace atomic absorption analysis.

Information related to flake graphite?

There are still many people who do not know some basic information about flake graphite. Therefore, as a manufacturer, it is necessary for us to explain briefly. In fact, flake graphite is a natural crystalline graphite, shaped like fish phosphorus, belonging to Hexagonal crystal family, with a layered structure. Now it is also a natural solid lubricant with a layered structure, rich in resources and low in price. This product has the characteristics of complete crystallization, good thin plate toughness, excellent physical and chemical properties, thermal conductivity, conductivity, thermal shock resistance, corrosion resistance, etc. It is widely used in refractory materials and coatings in the metallurgical industry, such as magnesia carbon bricks, crucibles, etc. Pyrotechnic material stabilizer in military industry, desulfurization accelerator in smelting industry, pencil lead in light industry, carbon brush in electrical industry, electrode in battery industry, catalyst in fertil

Graphite material properties

Graphite materials are mainly composed of polycrystalline graphite and belong to inorganic non-metallic materials. However, they are called semi metals due to their excellent thermal and electrical conductivity. Graphite has higher thermal and electrical conductivity than certain metals, and also has a much lower coefficient of thermal expansion, high melting point, and chemical stability than metals. This makes it of great value in engineering applications. Graphite has good corrosion resistance and does not react with any organic compoundsGraphite is another high-temperature resistant material that does not melt at high temperatures. It also has good thermal shock resistance and excellent self-lubricating propertiesThe disadvantage of graphite is its poor seismic performance. It begins to oxidize at 500 ℃ in the atmosphere, and the oxidation rate increases with the increase of temperature

Graphite electrode materials have the following six advantages

1、 Fast speed;Graphite discharge is 2-3 times faster than copper, and the material is not easily deformed. It has obvious advantages in the processing of thin ribbed electrodes. Copper has a softening point of around 1000 degrees, which is prone to deformation due to heating. The sublimation temperature of graphite is around 3650 degrees, and compared to copper, the thermal expansion coefficient of graphite material is only 1/30 of that of copper material;2、 Lightweight;The density of graphite is only 1/5 of that of copper. When using large electrodes for discharge machining, it can effectively reduce the burden on machine tools (EDM) and is more suitable for the application of large molds;3、 Low loss;Due to the presence of C atoms in spark oil, during discharge machining, high temperatures cause the C atoms in spark oil to decompose, forming a protective film on the surface of the graphite electrode, compensating for the loss of the graphite electrode;4、 No burrs;After the copper ele

Graphite

One of the main purposes of graphite is to produce refractory materials, including refractory bricks, crickets, continuous casting powder, molding cores, mold casting, detergent and high temperature resistance. In recent years, the two important changes in the refractory material industry are that magnesium carbon bricks are widely used in the inside of the steelmaking furnace, and the application of aluminum carbon bricks in continuous casting. The refractory material for graphite is closely connected to the steelmaking industry, and the refractory material consumed by the steelmaking industry around the world.Because graphite has many excellent performance, it has been widely used in industrial departments such as metallurgy, machinery, electrical, chemicals, textiles, and national defense.

The lubrication of sliced graphite is mainly reflected in two aspects

1. Silver-like Gention-Environmental atmospheric lubricationThe essence of lubrication of sheet -like graphite is its laminar crystal structure. The initial raw materials for preparation of expansion graphite are high -carbon -like graphite. Other chemical reagents such as concentrated sulfuric acid (more than 98%), hydrogen peroxide (more than 28%), and potassium permanganate are industrial -grade reagents. The general steps of preparation are as follows: At the appropriate temperature, add different proportion of hydrogen peroxide solution, natural scales and concentrated sulfuric acid to different programs, react for a certain period of time under continuous stirring, and then wash to neutrality, centrifugal, dehydrated, and dehydration. Dry vacuum at 60 ° C.2. Film graphite-solid lubricant and lubricant additiveThe lubrication performance of slices graphite is also affected by graphite particles.
