Product Description:


Graphite electrode is made from the domestic first petroleum coke and high  quality needle coke and widely used in the electric arc furnaces for production of alloy steels, metal and other nonmetallic materials, etc. The graphite      electrodes include regular power, high power, super high power, ultra high   power and square electrode. The range of diameters covers from 200mm to  700mm. Our products own the following characteristics: low electric          resistance, good electric and thermal conductivity, high oxidation resistance,  greater resistance to thermal and mechanicalshock, high mechanical strength, high machining accuracy.

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.
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: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.
Q:Why graphite can be used as conductive material?
Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at the temperature and at a high sliding speed, without lubricating oil work. Many transporting corrosive media devices are widely used, which is made of graphite material piston ring, the sealing ring and the bearing, they are running, without adding lubricating oil, graphite and many metal processing when good lubricant.
Q:Why should supercapacitors use graphite as electrode material?
Because graphite material processing speed is fast, the cost is low.
Q:What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found
The graphite part is called pyrolytic graphite. Stronger than ordinary graphite, strong oxidation resistance.
Q:The difference between graphite electrode and graphite rod
The two materials are different.Graphite electrode is mainly in the 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:What is the difference between SGL graphite electrode and graphite electrode in general?
Pure graphite is a kind of high-purity graphite. The processing technology of fine graphite and high purity graphite is basically the same, that is, the purity of graphite is different, the purity is higher, and the particle size is basically the same
Q:Will the brush grease not short-circuit the commutator?
The reverse pole surface should be clean and dry. Any grease, moisture or dust will destroy the carbon film on the commutator surface. The carbon film can not be formed or destroyed. It is very harmful. Grease material will be embedded in the joint between commutator and commutator. Under the action of electric spark, it will be carbonized and conductive. When serious, it will cause partial short circuit between the reversing pieces and reduce the service life of reversing.
Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
The temperature is not enough, the composition of graphite is carbon, of course, flammable, but each kind of object burning point is not the same, the nature of graphite is relatively stable, burning point is very high, cigarette lighter this temperature is certainly not burning up.Useful words, remember to adopt Oh, thank you ~!
