FAQ
- Classification, uses and manufacturers of graphite electrodes
- The difference between graphite electrodesMainly from the current, density, resistance, bending strength, ash parameters are measured
- Is graphite electrode good for foreign trade?
- Foreign sales commission depends on the price you talk to the customer, and the profit is objective.
- Why should graphite paper be placed between the heater and the graphite electrode?
- Heater design, the common heater has three shapes, cylinder, cup, spiral, the vast majority of the current heater is cylindrical, as shown in figure. The spiral heater has complicated processing technology and has been eliminated. Cup shaped heater for hemispherical crucible, the bottom melt temperature is more uniform, because the processing technology is difficult, already no use. Nowadays, most of them use cylinder heaters. The cylindrical heater is not only easy to process, but also is related to the large number of flat crucible used in the direct drawing single crystal furnace.
- How should carbon deposits be treated?
- At certain temperature, can make alloy and carbon can react in the engine surface coated with a layer of graphene film, graphene nano particles can fill the pores, wear scratches, on the friction surface repair function.
- I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?
- Is this principle. Graphite is a layer, each layer, each carbon is SP2 hybrid, and around three carbon connected, finally, between layer and layer formed delocalized covalent bond, making layer and layer can be connected. However, the delocalized covalent bond is not very stable, in attracting Yang Jizheng charge, delocalized covalent bond will certain destruction, the force between the graphite layer and the layer becomes small or not, so as to open.The black stuff is graphite
- Graphite electrode press device
- Ultra high power graphite electrodes. Use of graphite electrodes with a current density greater than 25A / cm 2. Used primarily in ultra high power arc furnaces
- 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
- Can Naiduo high temperature graphite
- Graphite cut gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc..
