Excellent characteristics of graphite plates

Graphite plate is a good technical property, and its good properties are widely used in various industries. Due to the excellent chemical and physical properties of the product, it has gradually become a key raw material for making grinding tools. Graphite belongs to the raw material of graphite carbon. During the production process, alkaline resistant organic chemical compounds are added, and then subjected to high-pressure manufacturing and forming. After undergoing high-temperature heat treatment, production and processing are carried out, thereby reducing the porosity of graphite products, improving the relative density of products, and possessing good alkali resistance and wear resistance. Graphite plates have high-quality characteristics and are suitable for industries such as forging, metallurgy, and grinding tools. CNC lathe processing machines and equipment further enhance the overall production and manufacturing level, and consider the requirements for precision and surface

High power and ultra high power electrodes

The characteristic of high-power and ultra-high-power electrodes is low resistivity, allowing for a current load of 25% -40% higher than that of ordinary electrodes; The allowable current density is greater than twice; Low coefficient of thermal expansion; High flexural strength; Low oxidation loss. The production of high-power and ultra-high-power electrodes uses needle coke as the raw material, and multiple impregnations are used in the production process to increase the graphitization temperature, and corresponding improvements are made to the bonding and impregnating agents.The requirements for ultra-high power graphite electrodes are relatively strict. The volume density of the electrode reaches 1.72g/cm3; The resistivity drops to 5-7 Ω. mX10-6. Due to the fact that the current density allowed by ultra-high power is more than twice that of ordinary electrodes, the thermal stress and impact it bears increase. Therefore, the electrode requires a low coefficient of thermal expansion

The Future Market Prospects of Graphite Powder

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
