A large amount of dispersed asphalt fume with a concentration of 5-7mg/m~3 is produced during the production process of the carbon workshop of the alumina plant. If it is directly discharged, it will have a serious impact on the surrounding environment and factory workers. Aiming at this pitch fu...
The use of graphite electrodes: used in steelmaking electric arc furnaces, refining furnaces, as conductive electrodes; used in industrial silicon furnaces, yellow phosphorus furnaces, corundum furnaces, etc., as conductive electrodes. The performance of graphite electrodes: good electrical condu...
Recent graphitized carburizing agent market price instability, to C≥98%, S≤0.05%, particle size of 1-5mm graphitized petroleum coking carburizing agent as an example, North China factory tax inclusive offer to maintain between 6550-6800 yuan/ton, East China factory tax inclusive offer to maintain...
Carburizers are divided into: petroleum coke carburizers, graphitized carburizers, natural graphite carburizers, metallurgical coke carburizers, calcined coal carburizers, natural graphite carburizers, and composite material carburizers. The main differences between graphite recarburizers and coa...
The UK’s national metrology institute NPL, in collaboration with international partners, announced on March 15 the development of the ISO/IEC standard ISO/TS 21356-1:2021 for measuring the structural properties of graphene, which is usually sold in powder form or . liquid dispersion. ISO/IE...
Compared with traditional crucibles, silicon carbide crucibles have many advantages such as strong high temperature resistance, high density, high thermal conductivity, small thermal expansion coefficient, and very resistant to corrosion by chemicals such as acids and alkalis. In addition, silico...
Research on the application of graphite crucible in industrial production is very common, many companies in the field of processing process design process is inevitable graphite crucible shadow, it can often be so popular is because there is a very key strong performance competitive advantage, gr...
The vacuum residue of petroleum is cracked and coked at 500-550 ℃ in the coking unit to produce black solid coke. It is generally believed that it is amorphous carbon, or a highly aromatic polymer carbide containing needle like or granular structure of micro graphite crystals. The hydrocarbon rat...
Needle coke is a silver-gray porous solid with obvious fiber texture direction, and has the characteristics of high crystallinity, high strength, high graphitization, low thermal expansion, low ablation, etc. It has special uses in national defense and civilian industries It is a high-quality raw...
