Production 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 mechanical shock, high mechanical strength, high machining accuracy.

 

Applications

Used in EAF and LF for steel making, as well as in electric smelting furnace for producing industrial silicon, phosphorus, etc.

Programmable properties
1.Good electrical conductivity
2.High resistance to thermal shock 
3.High mechanical strength

Grades:RP, RPI, HP, SHP, UHP

Graphite Electrode RP Grade

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: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:How long is the graphite electrode machining cycle?
When the cut depth is less than 0.2mm, the graphite will break down very little, and the surface quality of the side wall will be better.
Q:What are pyrolytic graphite electrodes used for?
In 1960s, copper is widely used as electrode material, usage rate of about 90%, about graphite only 10%; in twenty-first Century, more and more users start using graphite as the electrode material, in Europe, more than 90% above the graphite electrode material is. Copper, the once dominant electrode material, has almost lost its advantages over graphite electrodes.
Q:Is graphite electrode good for foreign trade?
I do graphite electrode production, but also do trade. The profit depends on the price you talked about. It should be around 2000.
Q:What do carbon products include?
High power electrode and ultra high power electrode. The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
Q:The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
Indeed, the original battery electrode potential using two different electrodes, produce potential difference, so that the electron flow generated current. Graphite is used as an electrode because of its excellent electrical conductivity and stability
Q:Will the brush grease not short-circuit the commutator?
Specifically: between motor brush and collector plus grease is redundant, but it is very harmful, fat instead will not play the role of good lubrication, it will destroy the good lubrication brush itself, not superfluous".
Q:What is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?
Carbon electrodes, however, are less likely to be less controllable because of their microstructure, or have some effect on the electric field, if they are sensitive signals
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.
We enjoy convenient access to major transportation networks. Furthermore, all our products are manufactured with advanced equipment and strict QC procedures in order to ensure high quality.
