FAQ:

Chemical Index of 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: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:What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised
Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
Aqueous solution electrolytic cell has no diaphragm and diaphragm. Two kinds of commonly used diaphragm electrolyzer. In chlorate production and mercury method to produce chlorine and caustic soda, with no diaphragm electrolyzer. Try to increase the surface area per unit volume, can improve the production strength of electrolytic cell. Therefore, the modern electrode diaphragm electrolyzer the vertical components due to internal electrolysis. The material and structure and installation of different performance and different characteristics.
Q:Why should the carbon brush for the trolley be made of graphite?
Graphite conducts electricity and is self lubricant, resistant to wear. As for why, high school chemistry textbooks have ah.
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:Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?
Because of the great loss of graphite electrode in finishing, it is not suitable to be used as finishing electrode material. Because of the small coefficient of thermal expansion of graphite, it can also be used as a big electrode material in perforation processing.
Q:Why use platinum ferroalloy instead of iron as electrode?
Its surface properties must comply with the characteristics of the additives so that they can be dispersed evenly.
Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
For the mold finishing, most of the time are red copper click, low loss, high precision, of course, higher precision, or requirements of copper tungsten alloy electrodes are also available
Q:Is graphite electrode good for foreign trade?
Foreign sales commission depends on the price you talk to the customer, and the profit is objective.
Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
The shorter one is the farther away from the other, and the shorter one is the shorter one
