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:Will the brush grease not short-circuit the commutator?
- The brush of motor is usually made of pure graphite electrode, electrochemical graphite electrode and metal fossil ink electrode material. Because it contains graphite, it has conductive effect on the one hand
- 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:Graphite graphite graphite graphite electrode what is the use?
- Electrode graphite powder that can be used for the production of electrodes, because the conductive properties of graphite electrode, so that the electrode graphite powder can become conductive graphite powder, graphite powder can also be applied to the field of conductive or conductive composite materials production.
- 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: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:What kind of asphalt is better for natural graphite coating?
- The graphite electrode includes: (1) ordinary power graphite electrode. Allows the use of current density below 17A / cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, refining yellow phosphorus, such as ordinary power furnace. (2) oxidation resistance 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. (3) high power graphite electrode. A graphite electrode with a current density of 18 ~ 25A / cm 2 is allowed to be used as a high power arc furnace for steelmaking. (4) ultra high power graphite electrode. Permits use of graphite electrodes with current densities greater than 25A / cm 2. Mainly used in ultra high power steelmaking arc furnace.
- Q:The use of graphite as an electrode in alumina electrolysis
- Graphite acts as an electrode:The electrical conductivity of graphite, the electrode itself must be electrically conductive;When graphite acts as an anode, it acts as a reducing agent and displaces an element of aluminum in a chemical reaction;Graphite is cheap and cost saving.
- Q:Can high-purity graphite be used as an electrode?
- The high purity graphite electrode has little wear and is suitable for increasing the machining of the cavity;
- Q:800KVA and 12500 EAF transformer data graphite electrode furnace.
- The graphite electrode must be roasted by a cathode or anode baking furnace, and a large amount of harmful gas and dust will be produced during the roasting process.
- Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
- Of course you do is oil cold if not toxic cooling but although graphite powder lubrication seems to have damage to the CNC, that someone with a water-cooled graphite again even with saponification liquid will rust and easy cleaning
