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

What are the characteristics of high-purity flake graphite

High purity flake graphite has good high-temperature resistance, conductivity, thermal conductivity, lubricity, and chemical stability. Graphite powder manufacturers are widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, fire protection, electronics, medicine, military industry, aerospace, etc. It plays an increasingly important role in the national economy and is an indispensable non-metallic raw material for modern industrial and high-tech development. Trace impurities have a significant impact on the performance of graphite products. The higher the carbon content of high-purity flake graphite, the better its performance as a functional material.In order to analyze trace impurities in high-purity flake graphite, the sample is usually ashed or wet digested to remove carbon, the ash is dissolved in acid, and the impurity content in the solution is then determined. The ashing method does not require the use of ultrapure acids to dissolve a

What should I pay attention to when applying graphite machinery and equipment

1. Be careful when transporting or hanging. Do not drag and drag it on the ground. Do not pry up or use a galvanized steel wire rope to be tied immediately. Essence2. After the total installation, when welding or oxygen cutting of the steel case, it should be ensured that the safety of graphite and hydraulic sealing should be ensured (water can be injected in the shell), otherwise graphite should be removed.3. When connecting the external flanges, it is not forcibly installed. When the foot bolts are tight, the symmetry is symmetrical.4. The export and export valve of the opening and closing machine equipment should be slow to prevent the significant impact of raw materials.5. The application of materials, temperature and work pressure in applications should be strictly strictly in accordance with the requirements of the design plan.6. For the electric heater, when driving, you should first pass the raw material and pass the vapor; when used as a cooling or cooler, you should first pa

Types and uses of carbon solid raw materials

Carbon graphite material is a granular structure material made from various raw materials with different particle sizes, through the addition of binders, kneading, forming, roasting, and graphitization. Therefore, the performance of materials is not only related to the particle size, type and dosage of binders, as well as process control and operation during the production process, but also to the type and performance of the raw materials themselves.There are many solid raw materials used in the production of carbon graphite materials, such as ordinary petroleum coke, needle shaped petroleum coke, asphalt coke, artificial graphite, natural graphite, carbon black, anthracite, metallurgical coke, charcoal, sugar charcoal, bone charcoal, and so on; For electrochar products, there are also metal powders such as copper, silver, tin, lead, and artificial resins; For mechanical carbon and furnace lining materials, as well as silicon carbide, carbon dioxide, and patterned clay; For carbon fib
