FAQ:

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

Chemical Index of Graphite Electrodes HP with Nipples

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: What is the difference between pyridine type nitrogen and graphite type nitrogen?: High purity graphite is said to produce graphite electrode, ash is very low, generally below 10 million.

Q: Graphite electrode specifications, graphite electrode manufacturers which good?: The key is you use and what type of need, say, abroad, what Dongyang, sigley are good, but also, very expensive, you can also choose to try our home

Q: Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?: Not alwaysIt depends on the rate of electrolyzed water or the rate at which sodium sulfite is oxidized.

Q: Specification for graphite electrodes commonly used in steel works: In general, the graphite electrode used in steelmaking furnace is mostly made of ordinary power and high power graphite electrode. Now, the use of ultra high power graphite electrode increases year by year, accounting for almost half of the graphite electrode.

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 high purity graphite component is put into the furnace, and nitrogen and methane are produced under vacuum high temperature. Then graphite is shown to produce 10% coating.

Q: What's the use of carbon?: Oxidation resistant coating graphite electrode. A graphite electrode coated with an antioxidant protective layer is applied to form a protective layer that is conductive and resistant to oxidation at high temperature, thereby reducing electrode consumption during steelmaking.

Q: Can graphite be used as an electrode for electrolysis of silver in silver nitrate?: Xiaoyi Liyang said the principle is correct, but can get silver? I think we can solve the problem if we take proper measures to get the silver elements, such as separating the anode and the cathode from the salt water!

Q: Graphite electrode press device: High power graphite electrodes. Graphite electrodes with a current density of 18 ~ 25A / cm 2 are allowed. They are mainly used in high power arc furnaces for steelmaking

Q: What does graphite electrode GSK mean?: Graphite is made of high-strength graphite, it is a kind of graphite grade specification.

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.
