FAQ:
Chemical Index of Graphite Electrodes UHP with Nipples
1. Why it is essential to select electrode carefully for each particular furnace?
The primary factor is the maximum current intensity of the furnace. However, other conditions should also be considered, such as the characteristics of the furnace, type of charge, tap to tap time, oxygen blowing, mechanical requirement, furnace regulation, etc.Generally, specifications for electrodes of most grades have been standardized. Variation of physical characteristics with temperature, however, should be taken into account whenever using the electrodes.
Precautions to the use of graphite electrodes
2. Why it is essential to not to fit electrodes and nipples made by different manufacturers together?
The capacities of the furnace and the transformer determine whether the grade and diameter of the electrode are suitable to the furnace or not.
In order to prevent the electrode column from being hit by the collapsed furnace loads, large and heavy scraps should be loaded onto the bottom of the furnace. Do not put significant quantity of insulating materials such as lime and so on just under the electrode column, otherwise it would be difficult to power on the electrode column, or even break it.
electrode column may be hurt when it moves up and down if the furnace cover is out of the position.
When making a connection, lost or damaged pitch plugs must be replaced.
The reason must be found out if a gap appears between two electrodes after connection. The electrode column can only be loaded after the gap being eliminated.
The electrode column must be strictly perpendicular to the ground lever. Oblique column is not allowed during operation.
The holder must be placed between the two safety marks on the top electrode, otherwise the column may be broken.
Generally, different manufacturers may make their electrodes with different raw materials and processes, therefore the physical and chemical properties of their electrodes are usually different. Please do not fit electrodes and nipples made by different manufacturers together.
Applications

Electrodes in electric arc furnace and ladle refining furnace for steel making;
Electrodes in electric smelting furnace for producing industrial silicon, yellow phosphorus, corundum and so on.
- Q: Why is graphite conductive electrode oxidized?
- Graphite electrode uses petroleum coke (carbon), pitch coke (carbon) as granule material
- Q: What is the striking electrode in the die making? Where is the technical point?
- Electrical discharge machining (EDM) is a spark discharge in a liquid medium at a lower voltage range to meet the required shape and size.
- Q: Why use platinum ferroalloy instead of iron as electrode?
- General industrial grade silicon dioxide, because the preparation technology is different, can be divided into two types, one is dry, sintered (Fume Type), a wet precipitation type (Precipitated Type), and two of the surface area, the surface with hydroxyl (-OH) are the same, in general, the former the latter is more, less, the two surface has the tendency of hydrophilic, as for lipophilic polymer, such as paint, rubber... Etc.,... If the silica surface pre rendered hydrophobic, has a good effect.
- 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: Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?
- Silicon carbide graphite is very famous for its high hardness and wear resistance. It is generally used in high wear resistance machinery industry and high wear resistant sealing industry.
- 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: Synthesis techniques of carbon nanotubes
- The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.
- Q: What is the application of wire cutting with graphite electrode?
- Machine: wire cutting wire, wire EDM, wire EDM wire is the cutting machine.
- Q: What are the losses in graphite electrode?
- So tell, this problem is to answer a lot, graphite under high temperature oxidation, generally around 400 degrees, began a slight oxidation, but the human eye is to be observed, with the increase of temperature, the graphite oxide will increase, this time should be used to protect gas or vacuum to protect what you said is, nitrogen protection, and general protection of nitrogen can reach more than 2000 degrees, if the high temperature to 3800 degrees, will you say that vapor formed in graphite surface. To achieve this temperature, it is necessary to add inert gas to achieve, otherwise, can not reach, generally to 4350 degrees, the graphite began to soften.
- Q: Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution
- Use a tight filter cloth as an anode pack
