Artificial graphite application field

In the metallurgical industry, natural scales can be used to produce refractory materials such as magnesium carbon bricks and aluminum carbon bricks due to better antioxidant properties. Artificial graphite can be used as a steelmaking electrode, and the electrodes made of natural graphite are difficult to use to use the steelmaking electric furnaces with strict conditions.In the machinery industry, graphite materials are usually used for wear -resistant and lubricating materials. The lubrication of natural scales graphite is better, which is often used as additives for lubricating oil. The device that transports the corrosive medium is widely used by artificial graphite pistons, sealing rings and bearings. There is no need to add lubricating oil during work. Natural graphite and polymer resin composite materials can also be used in the above fields, but wear resistance is not as good as artificial graphite.In the chemical industry, artificial graphite has the characteristics of corro

Graphite mold for antioxidant treatment

1. Heating and conductive: The heterogeneity of graphite is 300 times that of the normal non -non -non -metal mine. Conductivity surpasses non -metal materials such as steel, iron, lead. The conductivity coefficient increased with a decrease in measure, and even at a high degree, graphite became armatologist.2. Chemical stability: Graphite is excellent chemical stability at normal temperature, and the erosion of acid, alkali resistance and inorganic solvents.3. Smooth: The smooth function of graphite originated from the size of the graphite scales. The larger the scales, the smaller the conflict coefficient, and the better the smooth function.4. Plasticity: The graphite is tough and can be crushed into a thin crack. 5. Taxation shock: Graphite can be banned violently at the time of normal temperature and can be banned violently without destruction. When the measurement gradually changes, the volume of the graphite is not large and no cracks will occur.6. Low temperature resistance: T

The application of graphite powder in the field of lubrication

The lubrication performance of graphite powder is very good. It can be applied in the field of industrial lubrication production. There are many lubricating applications for graphite powder. This is to use different specifications of graphite powder. Graphite powder can play a lubricating role. The smaller the diameter, the better the lubrication effect of graphite powder. The lubrication application of graphite powder can be used to produce various lubricating products and materials.The lubrication application of graphite powder can directly produce lubricating materials, or it can be used as composite materials. It can be processed with other materials. It can be made into graphite solid lubricants, molding agents, lubricating wear -resistant coatings, etc. Graphite powder with lubrication is made of natural scale graphite crushing processing. The scale crystalline structure of natural scales graphite has a good lubrication performance. To better, the scale graphite must be crushed

The application of scales in the casting industry

1. Scales graphite is the main raw material for the casting industry.During the casting process, the scale graphite should be added to the casting, which helps the product to complete it faster and better, and improve the quality of the casting product. Therefore, the scale graphite for casting is the key raw material for the casting industry.2. How is graphite used to cast?Processing the cast -specific scales graphite into powder, and then add it to the outer surface of the casting and casting to make the casting easy to remove the mold. Casting dedicated scales graphite improves the surface quality of the casting, making the castings more abrasion and high temperature. This is the application of cast -specific scales graphite in casting and its abrasion resistance and high temperature resistance. There are many specifications for casting special sliced graphite powder. In different cast production areas, different thermal scale graphite should be used with different aims of casting.

What are the quality requirements for graphite electrodes used in DC arc furnaces

The graphite electrode used in DC arc furnaces has no skin effect when current passes through, and the current is evenly distributed on the current cross-section. Compared with AC arc furnaces, the current density passing through the electrode can be appropriately increased. For ultra high power electric furnaces with the same input power, DC electric arc furnaces only use one electrode, with a larger electrode diameter. For example, a 100t AC electric arc furnace uses electrodes with a diameter of 600mm, while a 100t DC electric arc furnace uses electrodes with a diameter of 700mm. Larger DC electric arc furnaces even require electrodes with a diameter of 750-800mm, and the current load is also increasing. Therefore, the following requirements are put forward for the quality of graphite electrodes:(1) The resistivity of the electrode body and joints should be smaller, such as the resistivity of the electrode body dropping to 5 μ Around Ω. m, the resistivity of the joint decreases to
