Q: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
Q:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
Not alwaysIt depends on the rate of electrolyzed water or the rate at which sodium sulfite is oxidized.
Q:Why is graphite a negative pole and copper is an anode?
Graphite, as an electrode material, can conduct electricity, which belongs to an inert electrode. It only acts as a conductive agent, but does not participate in the electrolytic reaction process. So the anode is made, and copper is oxidized in the electrolysis of monovalent cations, so copper is used as the anode.
Q:How about graphite electrode high-temperature oxidation resistant coating?
Heat resistant coating is generally able to withstand 300 degrees below the temperature, commonly used aluminum heat-resistant paint, high temperature resistance can withstand higher temperatures, such as 800 degrees or more, commonly used silicone heat-resistant paint
Q:What is the graphite furnace electrode with a diameter of 400?
With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
Q:Classification, uses and manufacturers of graphite electrodes
Graphite as electrode(1) the processing speed is faster: normally, the mechanical processing speed of graphite can be 2~5 times faster than copper, while the discharge processing speed is 2~3 times faster than copper;More material is not easily deformed: obvious advantages in the processing of thin electrodes; copper softening point at about 1000 degrees, easily deformed by heat; graphite sublimation temperature is 3650 degrees; the thermal expansion coefficient of copper is only 1/30.(2) lighter weight: the density of graphite is only 1/5 of copper. When large electrode is used for discharge machining, it can effectively reduce the burden of machine tools (EDM). It is more suitable for large-scale die applications.
Q:The production of one ton of steel required graphite electrode
Not sure, look at your such as what is charge, and your smelting level.If the proportion of molten iron to the furnace is high, then the electrode consumption is low, 0.7kg/t, or lower. If it's cold, 1-2kg/t.
Q:What is the difference between SGL graphite electrode and graphite electrode in general?
In fact, the graphite electrode abroad (including Japan) in several ways than we can control the fine, one is pure, another is anisotropic (resistance, thermal conductivity ah) usually do some control, in the strength of domestic now is also doing well, but when we are comparing high quality products, general domestic products it is basically a piece of the indicators are poor
Q:Classification of graphite electrodes
A graphite electrode with a current density of 18~25A/ cm 2 is used, which is mainly used in steel-making of high power arc furnace.
Q:What is the composition of petroleum coke and what is its use?
Medium sulphur and common cooked coke; used in large quantities for aluminium smelting. High sulfur, ordinary coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting and other fuels. Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used for smelting aluminium and making graphite.
