Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
The ultra high power graphite electrodes produced in China are 300mm, 350mm, 400mm, 450mm, 550mm, 600mm, 650mm, 500mm and 700mm, with lengths of 1600mm, 1800mm, 2000mm, 2200mm, 2400mm and 2700mm.
Q:Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?
Anodic iron is directly oxidized without oxygen generation
Q:What is anodized graphite?
Electrochemical graphite is made of graphite, coke and other raw materials, placed in the high temperature of more than 2500 degrees in the furnace, processed into products.
Q:How much does a graphite electrode cost about a ton?
According to purity and quality, the price is 1-6 tons / tonDo not calculate the processing cost
Q:Graphitized anode, cathode and graphite electrode, respectively How can one differentiate and use differently?
In an electrolytic cell, the current from a class called graphite anode plate into the electrolyte electrolysis industry, the anode is made of plate shape, so called graphite anode plate, widely used in electroplating, wastewater treatment, industrial anti-corrosion equipment or special materials.
Q:The production of one ton of steel required graphite electrode
Can not generally say, a ton of steel production consumes much of graphite electrode.
Q:What are the factors that affect the electrode wear rate of machine tools?
Influence of pulse interval on electrode wear. When the pulse interval is large, the electrode loss increases, which is due to the deterioration of the thermal effect condition and the damage of the "covering effect".
Q:Where is the graphite electrode scrap?
Vortex ring formed in a highly ionized internal ICP can be regarded as the secondary coil of the transformer is only one turn, and the work coil water is equivalent to the primary winding of the transformer, the coupling between them, the strength and direction of the magnetic field varies with time, the electronic and ionic field acceleration continuously changes its direction of motion. Lead to Joule heating effect and incidental ionization. This gas forms a new and stable "electric flame" light source in the quartz torch tube in a very short time.
Q:Classification, uses and manufacturers of graphite electrodes
The difference between graphite electrodesMainly from the current, density, resistance, bending strength, ash parameters are measured
Q:Which department in the steel plant needs graphite in large quantities?
For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.
