FAQ:

Electric Smelting furnace Furnace 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.

Applications

Electric Smelting furnace Furnace Graphite Electrodes UHP 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: Why graphite can be used as conductive material?: Graphite used in the electrical industry requires a high degree of particle size and grade. Such as alkaline batteries and some special electric carbon products, requiring graphite particle size control within the scope of the project, grade above, harmful impurities are required in the following. The graphite used in a picture tube for television is required below. As a wear-resistant and lubricating material, graphite is often used as a lubricant in the mechanical industry.

Q: What is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?: This kind of stable material because of the chemical properties is stable, is often used as a counter electrode. The electrode is composed of circuit and the working electrode by current.Pt electrode, carbon electrode are inert electrode, relatively stable, can be used as the electrode.

Q: What's the use of carbon?: Common power graphite electrode. Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.

Q: The production of one ton of steel required graphite electrode: Can not generally say, a ton of steel production consumes much of graphite electrode.

Q: What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?: 1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large

Q: How can the graphite powder be processed into high quality carburizing agent? Thank you: Basically, it can no longer be a "good" carburizing agent

Q: How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done: Infeasible!Iron plating is not easy because two - valent iron is not well - controlled with ferric ironGenerally, metal plating with multivalent States is not well controlled

Q: Carbon graphite electrode and what is the difference?: The material is composed of carbon carbon, but without graphite, after molding sintering temperature is only more than 1000 degrees, no graphitization.

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.
