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

- Q: Classification, uses and manufacturers of graphite electrodes
- Classification of graphite electrodes:(1) common power graphite electrode (RP), (2) high power graphite electrode (HP), (3) quasi ultra high power graphite electrode (SHP), (4) ultra high power graphite electrode (UHP) Note: poly carbon classification method
- Q: Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
- In anaerobic conditions, the ignition temperature is at least above 3000 degrees. There are many types of graphite, different types of ignition points, and the burning point of pyrolytic graphite...
- Q: Graphite electrode specifications, graphite electrode manufacturers which good?
- Graphite electrode has good electrical and chemical stability. It has high mechanical strength, low impurity content and good vibration resistance at high temperature. It is a good conductor of heat and electricity. Qingdao Chenyang graphite graphite electrode quality is good, they are a direct manufacturer of graphite electrode. Hope to be of some help to you.
- Q: Why should graphite paper be placed between the heater and the graphite electrode?
- Heater design, the common heater has three shapes, cylinder, cup, spiral, the vast majority of the current heater is cylindrical, as shown in figure. The spiral heater has complicated processing technology and has been eliminated. Cup shaped heater for hemispherical crucible, the bottom melt temperature is more uniform, because the processing technology is difficult, already no use. Nowadays, most of them use cylinder heaters. The cylindrical heater is not only easy to process, but also is related to the large number of flat crucible used in the direct drawing single crystal furnace.
- Q: The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
- Use oil cold. Air cooling will cause graphite dust flying, on the one hand, toxic, on the one hand there are security risks (caused by circuit short circuit). Water cooling is virtually out of use, taking into account the maintenance and maintenance of the CNC.
- Q: Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
- What happens is oxygen etching negative pole: Fe-2e-=Fe2+ positive electrode: O2+2H2O+4e-=4OH-, of course, the current is produced.
- Q: Graphite electrode press device
- High power graphite electrodes. Graphite electrodes with a current density of 18 ~ 25A / cm 2 are allowed. They are mainly used in high power arc furnaces for steelmaking
- 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.
- Q: Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?
- Look at what kind of graphite electrode you need. Now, the resistivity of ordinary power graphite electrode in our factory is 7.5-8.5. It is not clear that the graphite electrode is dipped in 6--7.3. copper
- Q: Graphitized anode, cathode and graphite electrode, respectively How can one differentiate and use differently?
- 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.
