FAQ:
Ladle Refining 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
Ladle Refining 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:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
- The difference is: the graphite bar may be machined graphite electrode materials may be insulated with material of graphite. Graphite electrode is an electrode product to guide the processing of graphite material with good electrical properties. Bars are usually cylindrical.
- Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
- Graphite is characterized by coarse particles, fine particles and ultrafine particlesFor different processing, you can choose different particles, the smaller the particle size, the higher the accuracyCopper has good conductivity and thermal conductivity and is used in many occasionsBut there are many factors to consider in the choice between the two
- 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.
- Q:Can high-purity graphite be used as an electrode?
- The utility model has the advantages of small density and suitable tool electrodes for processing large parts or moulds, and the whole quality is small.
- Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
- Or did you adjust the electrode when it was installed? There are two electrode distance, two away, causing melting after different lengths.
- Q:What are the skills of hardfacing process for wear-resistant alloy powder blocks?
- Because the carbon containing ash, a graphite resistor 2-3 times, so the use of graphite electrode is better.
- Q:What do carbon products include?
- High power electrode and ultra high power electrode. The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
- Q:What kind of asphalt is better for natural graphite coating?
- Special graphite mainly to high quality petroleum coke as raw material, coal tar or synthetic resin as binder, the raw material preparation, mixing, kneading, pressing, crushing, mixing, molding, roasting, soaking, repeatedly repeated purification and graphitization, and made the processing machine. It is generally used in the aerospace, electronics and nuclear industry sectors. It includes pure graphite, high purity, high strength, high density and pyrolytic graphite.
- Q:Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution
- Graphite as anode, generally do not need special treatment, but to choose high purity, high density, high strength (so-called "three high" graphite) graphite on the line, this graphite in brush plating operations are often used as anode material.
- Q:Why is graphite a negative pole and copper is an anode?
- The process of causing a chemical change by passing through a substance. Chemical change is the process in which material is lost or obtained by electrolysis (oxidation or reduction). Electrolysis is performed in an electrolytic cell. The electrolytic cell is composed of two electrodes, yin and Yang, which are respectively immersed in the solution containing positive and negative ions. The current into the negative electrode (cathode), are positively charged ions migrate to the cathode solution, and with the combination of electronic elements, become neutral or negatively charged molecules; negative ion transfer to another electrode (anode), electrons are given into neutral elements or molecules.
