Do you Know the Expansion Process of Graphite Electrodes?

  As a   Graphite Electrodes Exporter , share it with you. Gas generated inside the battery is an important cause of battery swelling. Whether the battery is stored at room temperature, high temperature cycle, or high temperature, it will produce different degrees of swelling and gas production. According to the current research results, the essence of the cell bloating is caused by the decomposition of the electrolyte. There are two cases of electrolyte decomposition. One is that there are impurities in the electrolyte, such as moisture and metal impurities, which cause the electrolyte to decompose and produce gas. The other is that the electrochemical window of the electrolyte is too low, which causes decomposition during the charging process. Solvents such as EC, DEC, etc. will generate free radicals after getting electrons. The direct consequence of free radical reactions is the production of low-boiling hydrocarbons, esters, ethers and CO2. HP Graphite Electrodes The thic...

Do you Know the Consumption of Graphite Electrodes in the Steelmaking Process?

  As a   Graphite Electrodes Solutions Supplier , I would like to share with you the consumption of graphite electrodes in the steelmaking process. Graphite Electrodes In the process of steelmaking, graphite electrodes will produce some consumption, which can be divided into normal consumption and extraordinary consumption. In normal consumption, there are three kinds of arc consumption, chemical consumption, and oxidation consumption.  1. Arc consumption is again called evaporation consumption, because there will be a high temperature of up to 3000 ℃ between the electrode and the charge, and there will be continuous consumption of the graphite electrode, which accounts for about 40% of the normal consumption. 2. Chemical consumption refers to the reaction between the electrode and some impurity iron, calcium, and manganese oxides in the steel or the reaction with the iron in the molten steel. This consumption is directly related to the quality of the steel and the diamet...

Do you Know the Feeding Control of Graphite Electrode?

  As a   Graphite Electrodes Manufacturer , share it with you. The cost of charging (scrap, DRI, molten iron) may be the most variable factor in the cost of graphite electrode steelmaking. Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000°C. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in a neutral or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13)×10-6 Ω·m, processability is better than SiC, MoSi2 rod, high temperature resistance, extreme cold and extreme heat resistance, good price Cheaper.  Graphite Electrodes Graphite block is a kind of artificial graphite, and artificial graphite is made by artificial heating of coke products. Generally, if it is purified to make high purity, or carbon fiber, the added value is high. Graphite electrodes are mainly made of petroleum cok...
