- Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
- Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%
- Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
- Connect the fan with a thicker pipe and suck it out of the workshop. The air inlet is mounted on the milling head. Reduce milling speed properly.
- Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
- The ultra high power graphite electrodes produced in China are 300mm, 350mm, 400mm, 450mm, 550mm, 600mm, 650mm, 500mm and 700mm, with lengths of 1600mm, 1800mm, 2000mm, 2200mm, 2400mm and 2700mm.
- Q:Where is the graphite electrode scrap?
- Vortex ring formed in a highly ionized internal ICP can be regarded as the secondary coil of the transformer is only one turn, and the work coil water is equivalent to the primary winding of the transformer, the coupling between them, the strength and direction of the magnetic field varies with time, the electronic and ionic field acceleration continuously changes its direction of motion. Lead to Joule heating effect and incidental ionization. This gas forms a new and stable "electric flame" light source in the quartz torch tube in a very short time.
- Q:Thermal expansion coefficient of graphite
- Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius
- Q:Synthesis techniques of carbon nanotubes
- The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.
- Q:National standard for graphite electrodes
- Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB
- Q:What kinds of carbon are there?
- The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
- Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
- For example, according to connection of the electrode, which can be divided into two types of unipolar and bipolar type electrolyzer (see photo). The electrode is connected with the DC power supply parallel polarity monopolar electrolyzer, electrodes on both sides of the same, at the same time as anode or cathode. At the same time as the positive and negative electrode bipolar type electrolyzer ends respectively with DC power supply connected, as anode or cathode. The current through the electrode through the electrolysis cell in series, each side of the intermediate electrode as the anode, the other side is the cathode, so it has a bipolar electrode. When the total area at the same time, the current bipolar type electrolyzer is small, high voltage DC power supply, the required investment ratio monopolar, bipolar type filter press used. The general structure, more compact. But easy to leakage and short circuit, slot structure and operation management is more complex than the monopolar type. The monopolar electrolyzer section is generally rectangular or square, cylindrical covers a large, empty The utilization rate is low and the adoption rate is less
- Q:Graphitized coke, graphite, broken, mixed up, how to export?
- The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
