2. Introduction of Graphite Electrodes

G-High Graphite Electrodes have the properties of superior electric conductivity and chemical stability, high mechanical strengt

G-High Graphite Electrodes are made from Petroleum Coke and Needle Coke, using Coal Tar Pitch as agglutinant, produced through the process of calcining, mixing, kneading, compressing, roasting, graphitization and machining, etc.

G-High Graphite Electrodes have the properties of superior electric conductivity and chemical stability, high mechanical strength, less impurity, seismic performance in high temperature. G-High Graphite Electrodes are mainly used for steel-making in electric furnaces, mineral hot furnaces and electric resistance furnaces.

Graphite Electrodes conduct electric current into the furnace. Electric current produces arc in the smelting district, when the temperature increases to about 2000°C, smelting begins. Our series of Graphite Electrodes are applicable to the common furnaces and high power furnaces with high voltage and short arc. G-High Graphite Electrodes are classified into three classes.

NP Graphite Electrodes: mainly used in common power electric ovens for smelting steel, smelting silicon and smelting yellow phosphorus;  

HP Graphite Electrodes: mainly used in high power electric ovens for smelting steel;

UHP Graphite Electrodes: mainly used in ultra high power electric ovens for smelting steel.

Q:Graphite electrode specifications, graphite electrode manufacturers which good?
Graphite electrode has good electrical and chemical stability. It has high mechanical strength, low impurity content and good vibration resistance at high temperature. It is a good conductor of heat and electricity. Qingdao Chenyang graphite graphite electrode quality is good, they are a direct manufacturer of graphite electrode. Hope to be of some help to you.
Q:How do graphitized electrodes differentiate between high power and low power?
In electrolysis industry, using graphite anode plate as the anode has a history of more than 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages.
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 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:How much does a graphite electrode cost about a ton?
Electrode is divided into ordinary power motor, high power electrode, ultra high power electrode, the gap between the price is still relatively large
Q:What is the composition of petroleum coke and what is its use?
Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.
Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
For example, the electrode is large, and this time it is necessary to consider whether the weight of the electrode is up to standard and, if so, the preferred graphite electrode
Q:Will the brush grease not short-circuit the commutator?
Graphite, on the other hand, has good lubrication. The graphite base electrode will form a layer of carbon film when it rotates on the surface of the motor commutator. It can reduce the friction coefficient between the brush and the commutator and reduce the wear of the commutator effectively.
Q:Electrolytic salt water why use iron as a cathode, all with graphite can not?
Although iron and graphite can be used, it is better to use iron as the cathode: 1, because the cathode will be protected when it is electrolytic, that is to say, iron will be protected and will not lose electrons
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.
