Large Size Carbon Electrode CNBM China 500--700

Large Size Carbon Electrode CNBM China 500--700


Q: Thermal expansion coefficient of graphite
Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius
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: Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
No, sodium sulfite reacts with the oxygen produced.
Q: National standard for graphite electrodes
The national standard normal power graphite electrode graphite electrode: the standard name standard classification number Q51 Standard No. YB/T 4088-2000 for YB/T 4088-2000 YB/T 4088-1992 2000/12/1, instead of the execution time of 0:00:00 release time 2000/7/26 0:00:00 adoption situation
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: How much does a graphite electrode cost about a ton?
Electrode is divided into ordinary power motor, high power electrode, ultra high power electrode, the gap between the price is still relatively large
Q: How can the graphite powder be processed into high quality carburizing agent? Thank you
Basically, it can no longer be a "good" carburizing agent
Q: What about graphite electrodes for steel mills?
Hebei North graphite electrode factory produces various specifications of graphite electrode, with low resistance, high density, small ash, and so on, so that less tons of steel-making, quality is good
Q: How do graphitized electrodes differentiate between high power and low power?
In electrolysis industry, using graphite anode plate as the anode has a history of more than 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages.
Q: What is the composition of petroleum coke and what is its use?
Medium sulphur and common cooked coke; used in large quantities for aluminium smelting. High sulfur, ordinary coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting and other fuels. Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used for smelting aluminium and making graphite.
