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.

Q:How to improve the efficiency of graphite electrode milling, please tell me
There are many factors that determine the need to continue producing graphite electrodes, so high-speed machining has become a key manufacturing process in the die manufacturing industry. Compared with the time required for the milling of graphite electrodes, the processing of high rigidity hard steel still takes longer. When milling dies, cavities, and complex 3D surfaces on hard steel, radial runout errors and tool deviations often result in fracture of the tool. When the tool is broken, it will not only stop the continuous processing of the steel, but also affect the quality of the product, which will lead to the scrap of the parts and the waste of the material.
Q:What is the striking electrode in the die making? Where is the technical point?
Technology of EDM should master the characteristics of electric discharge between tool electrode and workpiece is not in direct contact, but there is a gap, the gap is generally between 0.05~0.3mm, sometimes may reach 0.5mm or more, full of fluid, processing by high voltage pulsed discharge, the discharge of corrosion the workpiece.
Q:The reason why graphite is used as electrode
The graphite has good conductivity and thermal conductivityThe conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. Heat conductivity exceeds steel, iron, lead and other metal materials. The coefficient of thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, the graphite becomes hot.
Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
In the electric arc furnace, the electric energy is released in the form of an arc, and the conductor is heated and melted. According to the quality index, the conductor can be divided into ordinary power, high power and ultra high power.
Q:What is the difference between SGL graphite electrode and graphite electrode in general?
Can not say that the more detailed the better, is relative, must be uniform within the range (after all, it is very important to choose the aggregate), such as spectral pure graphite, is not due, he is a lot of technology to producing stains, then burning, and then producing stains, the strength is quite good,
Q:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
Can't。 During electrolysis, there is depletion of sulfite ions.
Q:What is the graphite furnace electrode with a diameter of 400?
The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.
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: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:The future of graphene
A report released recently pointed out that the Chinese Academy of Sciences, graphene research and industrialization continues to heat up, from the distribution of graphene patents in the field, including the application of technology research hot spots: layout of graphene as a electrode material of lithium ion batteries, solar battery electrode materials, thin film transistor preparation, sensor, semiconductor device, composite material preparation of transparent, touch screen display, transparent electrode
