- Q: Why is graphite conductive electrode oxidized?
- Coal tar pitch is a kind of high temperature resistant graphite conductive material, which is made of coal tar pitch as binder. It is made by calcination, crushing, mixing, kneading, forming, roasting, graphitization and mechanical processing. It is called graphite electrode
- Q: Why should supercapacitors use graphite as electrode material?
- Because graphite material processing speed is fast, the cost is low.
- Q: Use of graphite in steelmaking
- At present in the world (MgO-C brick raw material for graphite and magnesium) as refractory material, has been widely used in steelmaking, has become a traditional use of graphite.
- Q: Which department in the steel plant needs graphite in large quantities?
- For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.
- Q: What kind of asphalt is better for natural graphite coating?
- Main types of graphite electrode with petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
- Q: Can graphite be used as an electrode for electrolysis of silver in silver nitrate?
- If it is molten, it can be made out of silverFor solution, only AgNO3+H2O== electrolysis ==Ag+HNO3+O2 is analyzedWhen the HNO3 concentration is enough, it will continue to react with Ag.... So you can't get Ag elements.
- Q: Why should graphite paper be placed between the heater and the graphite electrode?
- Determine the thickness of the graphite bowl, the thickness of the graphite bowl is generally 3 mm -6 mm, three, determine the diameter of the heater, according to the diameter of the crucible and the thickness of the graphite bowl, calculate the inner diameter of the heater. The gap in the quartz crucible diameter phi = +2 times is +2 times the wall thickness of stone bowl bowl and graphite heater if the graphite bowl wall thickness is a, graphite bowl gap and heater for B (b=5 mm), phi = Phi Phi +2a+2b= within the outer crucible outer crucible +2 (a+b) four, to determine the effective heater the height after practice, the effective length of the quartz crucible heater is high 1.6 to 1.8 times.
- Q: Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
- Ultra high power electrode of the main raw material is coke, but in order to increase the strength of the product will add some metallurgical coke, another is in the process of producing stains in coal tar pitch in after graphitization has become one of the A
- Q: What about graphite electrodes for steel mills?
- The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys
- Q: How about graphite electrode high-temperature oxidation resistant coating?
- Can be used, temperature characteristics of nano composite ceramic coating is more stable, and nano composite ceramic nano high temperature oxidation resistant coatings of different graphite products according to the use conditions, can the temperature of 1600 degrees, forming a dense coating on graphite coated with rust, corrosion, high temperature resistance, oxidation resistance, wear resistance and other properties.
