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: 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: Use of graphite in steelmaking
- Application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees Celsius, so as to achieve the purpose of melting or reaction.
- Q: What is the difference between pyridine type nitrogen and graphite type nitrogen?
- The fine structure graphite is the raw material used in the production of graphite electrode. The particle size is relatively small, generally below 0.5.
- Q: In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
- For operators, copper is certainly better, graphite will have dust, the human body has serious harm
- Q: Can Naiduo high temperature graphite
- Graphite gasket medium: hot water, steam, oil, acid, alkali, ammonia, hydrogen, organic solvents, hydrocarbons, cryogenic liquids, etc..Maximum use pressure of graphite gasket: 30MPa.Service temperature of graphite gasket: -200~650
- Q: Can high-purity graphite be used as an electrode?
- High purity graphite can be used as electrode, high purity graphite as electrode has many advantages. According to the research of Qingdao Huatai graphite, we can see: 1, high purity graphite electrode is quick in opening and good in air permeability;
- Q: What is anodized graphite?
- According to the production method of brush, there are two kinds. One is colored brush, that is, metal graphite brush. One is black brush. The black brush is made of petroleum coke, pitch coke, carbon black, charcoal and natural graphite powder and so on. Some binders (such as coal tar pitch, coal tar and artificial resin etc.) are added to the black brush. The resin binder by curing brush manufactured for high resistance brush, and the calcined product called carbon brush and graphite brush (with natural graphite as the main raw material) graphitised after product called electrographite brush,
- Q: Electrolysis of CuCl2 solutions with graphite electrodes
- CuCl2 refers to a copper chloride ionization ionization ion and chloride ion in aqueous solution, the equivalent of CuCl2 does not exist, but there are only Cu2+ and Cl-, even if there is no electricity, the ionization will happen, because this is the nature of it.
- Q: Graphitized anode, cathode and graphite electrode, respectively How can one differentiate and use differently?
- In an electrolytic cell, the current from a class called graphite anode plate into the electrolyte electrolysis industry, the anode is made of plate shape, so called graphite anode plate, widely used in electroplating, wastewater treatment, industrial anti-corrosion equipment or special materials.
