FAQ:

Industrial Silicon Producing 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: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
Q:The production of one ton of steel required graphite electrode
Not sure, look at your such as what is charge, and your smelting level.If the proportion of molten iron to the furnace is high, then the electrode consumption is low, 0.7kg/t, or lower. If it's cold, 1-2kg/t.
Q:Graphitized coke, graphite, broken, mixed up, how to export?
The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
Q:What does graphite electrode GSK mean?
Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
The structure of the electrolytic cell is different when the electrolytic cell is constructed with different electrolytes
Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%
Q:How does graphite produce solar cells?
In addition, the Research Report of the first author, Massachusetts Institute of Technology Department of materials science and engineering postdoctoral Zhang Shenggen said, different from other semiconductor temperature has been rising continuously, the graphite electrode coating Zinc Oxide nanowires can be temperature controlled at 175 degrees celsius.
Q:Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?
Look at what kind of graphite electrode you need. Now, the resistivity of ordinary power graphite electrode in our factory is 7.5-8.5. It is not clear that the graphite electrode is dipped in 6--7.3. copper
Q:Synthesis techniques of carbon nanotubes
Catalytic pyrolysis is one of the widely used methods for preparing carbon nanotubes. The method mainly uses transition metal as catalyst, and is suitable for large-scale preparation of carbon nanotubes. The content of carbon nanotubes in the products is higher, but the defects of carbon nanotubes are more.
Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
Coal tar pitch as binder is made by calcination, batching, kneading, pressing, roasting, graphitization and machining
