FAQ:

Graphite Electrodes UHP with Nipples for Electric Arc Furnace

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

Graphite Electrodes UHP with Nipples for Electric Arc Furnace

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:How should carbon deposits be treated?
It is very necessary to clean the throttle valve, clean the nozzle, and clean the carbon in the engine cylinder! However, in order to reduce the trouble of cleaning, it is best to join the regular application of graphene Moqi additive in lubricating oil for engine.
Q:Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?
The main components of carbon electrodes are graphite, carbon powder and other impurities which are not converted into graphite. The resistivity is higher than that of graphite electrode. These electrodes are mostly used in electric furnace steelmaking, smelting aluminium oxide and other electric arc furnaces.
Q:How do graphitized electrodes differentiate between high power and low power?
Compared with other materials of graphite anode plate has high temperature resistance, good electrical and thermal conductivity, easy machining, good chemical stability, acid and alkali resistance, low ash content; for electrolytic solution, preparation of chlorine, caustic soda, salt alkali electrolytic solution preparation; application such as graphite anode plate can be used as conductive anode electrolytic salt solution preparation of caustic soda. Graphite anode plate can be used as conductive anode in electroplating industry. It is an ideal material for electroplating. It can make electroplating products have the advantages of smoothness, delicacy, wear resistance, corrosion resistance, high brightness and not easy to change color.
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 do carbon products include?
Carbon and graphite materials are mainly carbon based non-metallic solid materials, in which carbon material is basically composed of non graphitic carbon material, and graphite material is basically composed of graphite carbon material. For the sake of simplicity, carbon and graphite materials are sometimes referred to as carbon materials (or carbon materials).
Q:National standard for graphite electrodes
The national standard normal power graphite electrode graphite electrode: the standard name standard classification number Q51 Standard No. YB/T 4088-2000 for YB/T 4088-2000 YB/T 4088-1992 2000/12/1, instead of the execution time of 0:00:00 release time 2000/7/26 0:00:00 adoption situation
Q:I remember the more lively metal, the electron?
Metal ion is more inert electron, graphite electrode for electrolytic salt solution containing the same amount of substance A and C two metals, C first precipitated, so C is copper. In a dilute sulfuric acid with H2 precipitation, certainly not a copper. The more active metal betatopic ability is strong, have the corresponding ion electronic ability weaker. First metal ions corresponding to metal electrons are not active.
Q:Can graphite be used as an electrode for electrolysis of silver in silver nitrate?
If it is molten, it can be made out of silverFor solution, only AgNO3+H2O== electrolysis ==Ag+HNO3+O2 is analyzedWhen the HNO3 concentration is enough, it will continue to react with Ag.... So you can't get Ag elements.
Q:How to solve the problem of graphite electrode being crushed during electrolysis
I can only use the experience of the past to tell you that if you want to save money easily, the time can be considered as the costA thick graphite stick; inexpensive
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.
