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:Synthesis techniques of carbon nanotubes
- The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.
- Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
- Graphite rod refers to graphite rod without processing. A graphite electrode refers to a finished product.
- Q:I remember the more lively metal, the electron?
- C metal is copper, because a dilute sulfuric acid into the H2 precipitation, then definitely not copper. And the inactive first precipitate
- Q:What are the factors that affect the electrode wear rate of machine tools?
- Effect of processing voltage on electrode wear. The processing voltage is the average voltage between the discharge time and the gap. When the voltage is lower than the power supply voltage (voltage) 25%, electrode loss will increase, which is due to the electrode and the workpiece is too close, the discharge column energy is too large, the electrodes generate heat radiation is too strong, at the same time, there are a large number of continuous arc discharge. But the working voltage is too high (partial load processing), bad conditions of thermal effect in the gap, is not conducive to the adsorption of copper electrode of carbon graphite, destroy the covering effect. Similarly, the electrode loss increase, therefore, corresponding to different processing standards should be selected to adjust the discharging gap voltage.
- Q:Graphitized coke, graphite, broken, mixed up, how to export?
- The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
- Q:Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?
- This is not a good estimate of the sheet graphite resistance after 5mm
- Q:Electrolysis of CuCl2 solutions with graphite electrodes
- After energization, electrolysis occurs, not ionizationIonization does not require energization, and can occur in aqueous or molten state.
- Q:The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
- Indeed, the original battery electrode potential using two different electrodes, produce potential difference, so that the electron flow generated current. Graphite is used as an electrode because of its excellent electrical conductivity and stability
- Q:What does graphite electrode GSK mean?
- Graphite board material is GSK, GSK refers to model specifications
- Q:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
- No, sodium sulfite reacts with the oxygen produced.
