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: Why is graphite conductive electrode oxidized?
- Coal tar pitch is a kind of high temperature resistant graphite conductive material, which is made of coal tar pitch as binder. It is made by calcination, crushing, mixing, kneading, forming, roasting, graphitization and mechanical processing. It is called graphite electrode
- Q: Why should supercapacitors use graphite as electrode material?
- Because graphite material, light weight, good thermal conductivity and conductivity.
- Q: Thermal expansion coefficient of graphite
- The graphite electrode in the thermal expansion coefficient is related with the diameter of the graphite electrode, you have what is the expansion coefficient of specific diameter range not to say it, I put the general heat on high power graphite electrode national Ministry of metallurgical industry YBT/4089--2000 give you a lower coefficient of expansion. For reference only
- Q: Why graphite can be used as conductive material?
- Widely used as electrode, graphite, carbon brush, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating and so on in the electrical industry. The most widely used in the smelting of graphite electrode, 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 around, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace used for the production of rigid sand is also made of graphite electrode as the conducting material of the furnace head.
- Q: Why should the carbon brush for the trolley be made of graphite?
- Graphite has good conductivity
- Q: Why should graphite paper be placed between the heater and the graphite electrode?
- . Different single crystal furnace heaters may be of the same size or may be different. The heater is determined according to the size of the Czochralski single crystal furnace and the parameters of the drawn single crystal, and is generally designed in the form of a parallel circuit, and the following parameters. A heater, the heater, the shape of two inner diameters of three, four, the effective length of the heater heater, the heater piece is five thickness and gives the heater diameter. These parameters are determined according to Czochralski single-crystal furnace parameters and its crystal diameter. The power transformer parameters are mainly based on the single crystal furnace heating power: maximum output power, maximum output voltage and maximum output current, diameter and height of the crucible. The design of the heater has the following steps: 1. Selecting and determining the shape of the heater; the heater is made of high purity graphite; the resistivity of the high purity graphite; the heater is usually made into a cylinder at present.
- Q: How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?
- Molten sodium hydroxide is ionized out of Na+ and OH-, electrons are lost at the anode OH-, oxygen and water are produced (immediately evaporated at high temperature), and electrons are generated at Na+ at the cathode Na
- Q: What about graphite electrodes for steel mills?
- Hebei North graphite electrode factory produces various specifications of graphite electrode, with low resistance, high density, small ash, and so on, so that less tons of steel-making, quality is good
- Q: What are pyrolytic graphite electrodes used for?
- In 1960s, copper is widely used as electrode material, usage rate of about 90%, about graphite only 10%; in twenty-first Century, more and more users start using graphite as the electrode material, in Europe, more than 90% above the graphite electrode material is. Copper, the once dominant electrode material, has almost lost its advantages over graphite electrodes.
- Q: How about graphite electrode high-temperature oxidation resistant coating?
- The utilization ratio of graphite energy can reach more than 95%. Many kinds of antioxidant paint, it is recommended to directly find their technicians, you can give professional advice, according to the actual situation, the reasonable use of high-temperature oxidation resistant paint.
