Product Description:

Description: 

Graphite electrode is made from the domestic first petroleum 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.

 

Graphite Electrodes Features:

 

RP HP UHP Graphite Electrode 
1.Dia:40-600mm or1.6"-24"
 
2.Length:250-2400mm or10"-96"
 
3.Nipples:3TPI,4TPI

Graphite Electrodes Application:

 

An increasing proportion of global steel is made using electric arc furnaces, and the electric arc furnace itself is getting more efficient and making more steel per tonne of electrode

 

Graphite Electrodes Specifications

 

Do you know our material of the graphite electrode? 

The regular power graphite electrode is made from petroleum coke with a little pitch, which meets the state standards YB/T4088-2000

 

The high power graphite electrode is made form 70% petroleum coke and 30% imported needle coke, which meets the state standards YB/T4089-2000

Q:The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
External electronic wire and the directional movement of ions in the solution of the directional movement between the poles of a closed loop, so that the two electrode reaction, electron transfer process, ordered a current converting chemical energy to electrical energy.Attention, here, "the ion does not go ashore, the electron does not enter the water"." That is the external circuit of graphite electrode is composed of electron flow and electrolyte ion flow; graphite electrode is to produce voltage and electrolyte, and to provide or absorb electrons
Q:What about graphite electrodes for steel mills?
Hebei North graphite electrode factory produces various specifications of graphite electrode, with low resistance, high density, small ash, and so on, so that less tons of steel-making, quality is good
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:Why should graphite paper be placed between the heater and the graphite electrode?
. Different single crystal furnace heaters may be of the same size or may be different. The heater is determined according to the size of the Czochralski single crystal furnace and the parameters of the drawn single crystal, and is generally designed in the form of a parallel circuit, and the following parameters. A heater, the heater, the shape of two inner diameters of three, four, the effective length of the heater heater, the heater piece is five thickness and gives the heater diameter. These parameters are determined according to Czochralski single-crystal furnace parameters and its crystal diameter. The power transformer parameters are mainly based on the single crystal furnace heating power: maximum output power, maximum output voltage and maximum output current, diameter and height of the crucible. The design of the heater has the following steps: 1. Selecting and determining the shape of the heater; the heater is made of high purity graphite; the resistivity of the high purity graphite; the heater is usually made into a cylinder at present.
Q:Thermal expansion coefficient of graphite
Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius
Q:What are the skills of hardfacing process for wear-resistant alloy powder blocks?
The hardfacing of wear-resistant alloy powder block is mostly made by carbon arc surfacing. General selection of graphite or carbon arc surfacing carbon rod and plate electrodes, which has good conductivity, high melting point;
Q:Graphite electrode specifications, graphite electrode manufacturers which good?
The key is you use and what type of need, say, abroad, what Dongyang, sigley are good, but also, very expensive, you can also choose to try our home
Q:I remember the more lively metal, the electron?
C metal is copper, because a dilute sulfuric acid into the H2 precipitation, then definitely not copper. And the inactive first precipitate
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:How can the graphite powder be processed into high quality carburizing agent? Thank you
If you are through the material can also be screened and then sold, usually 1-5 of the particle size, fine powder can only add adhesive column
