FAQ:

Electric Smelting furnace Furnace 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.

Q:The reason why graphite is used as electrode
Graphite is good in plasticity and easier to be machined preciselyGraphite material has the advantages of high processing accuracy and good surface effect, especially in the processing of precise, complex, thin-walled and Gao Ying material mold cavity. Because the cutting resistance of graphite is only 1/5 of copper material, it is easier to do manual grinding and polishing on the operation. There is no burr after graphite processing, and it is easier to realize automatic production. Complex geometric modeling can be realized.
Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
The difference is: the graphite bar may be machined graphite electrode materials may be insulated with material of graphite. Graphite electrode is an electrode product to guide the processing of graphite material with good electrical properties. Bars are usually cylindrical.
Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?
Carbon deposition can cause insufficient combustion of gasoline and cause engine chattering.
Q:How large is the permissible overload current per square millimeter of the graphite electrode cross section?
Overhead wires, radiating the best conditions, allowed the current largest. The insulated wire in the house is laid in the wall, which has the worst heat release conditions and the smaller permissible current, so there are different safety currents.
Q:Electrolysis of CuCl2 solutions with graphite electrodes
The energization is the electrolysis of CuCl2 solutions, i.e., redox reactions. So you can't mix ionization and electrolysis.
Q:Where is the graphite electrode scrap?
Atoms, ions, and electrons collide with each other in strong oscillatory motion to produce more electrons and ions.
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:Why should supercapacitors use graphite as electrode material?
Because graphite material, light weight, good thermal conductivity and conductivity.
Q:Synthesis techniques of carbon nanotubes
Carbon nanotube discharge using graphite electrode is one of the earliest studies in various synthetic techniques. The researchers did a lot of work in optimizing arc discharge for carbon nanotubes. In recent years, in addition to people by adjusting the current and voltage, pressure and velocity change, change the electrode composition, improved electrode feeding mode optimization of arc discharge process, but also through changes the arc medium, simplified arc device. In the process of preparing carbon nanotubes, arc method is mature by changing the arc discharge conditions, catalyst, electrode size, feed mode, the distance between the poles and the raw materials. The carbon nanotubes formed by arc method are straight and wall (multi wall or even single wall). But the production rate is low, the arc discharge process is difficult to control, and the preparation cost is too high. The industrial scale production needs to be explored.
Q:How does graphite produce solar cells?
Gerrit J said: "despite the modifications, but the inherent nature of graphene remains unchanged, is a significant advantage of composite materials."
