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

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 diameter of the graphite electrode. 

3. Oxidation consumption refers to the consumption caused by the reaction with oxygen in the process of steelmaking. It is related to the atmosphere, gas temperature and gas flow rate in the furnace. It is found in the normal consumption of 50%-60%, which is the largest consumption. 

4. Extreme consumption is the breakage of the machine when it is used.

What are Graphite Electrodes and Needle Coke?

  As a   Graphite Electrodes Manufacturer , share with you. Graphite electrodes are the main heating element used in electric arc furnaces, which is a steelmaking process that melts scrap from old cars or old home appliances to produce new steel. The construction cost of an electric arc furnace is cheaper than that of a traditional blast furnace, which is made of iron ore to make steel and is fueled by coking coal. However, steelmaking costs are higher because they use scrap steel and are driven by electricity. Graphite Electrodes The electrode is a part of the furnace cover and is assembled into a cylinder. Then, the current passes through the electrodes, forming a strong arc, melting the scrap. The size of the electrodes varies greatly, but the diameter can reach 0.75 meters (2 and a half feet), and the longest can reach 2.8 meters (9 feet). The largest weighs more than two metric tons. Up to 3 kilograms (6.6 pounds) of graphite electrodes are required to produce one ton of ...

How to Deal With the Details of Graphite Electrode Use?

图片
  As a   Graphite Electrodes Manufacturer , share with you. We need to know that the wet graphite electrode should be dried before use, and the internal thread of the electrode hole should be checked for integrity. When we clean the surface of the spare graphite electrode and the internal thread of the hole with compressed air, there must be no oily water; avoid cleaning with steel wire or metal brush cloth. Graphite Electrodes It is important to carefully screw the connector into the electrode hole of the spare graphite electrode, and screw the electrode strap (graphite strap is recommended) into the electrode hole on the other end of the spare electrode. When lifting the electrode, the cushion is soft to the bottom of one end of the spare electrode assembly connector to prevent ground damage and connector damage; the lifting hook extends to the lifting ring of the lifting device to lift, the lifting electrode is smooth, preventing the electrode from being released from the B...

Do you know the Bending Strength and Average Particle Size of Graphite Electrode Materials?

图片
  As a   Graphite Electrodes Manufacturer , share it with you. The bending strength of graphite electrode materials and the bending strength of graphite electrode materials are a direct reflection of the strength of the material, reflecting the compactness of the internal structure of the material. 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 rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000℃. It is easy to oxidize at high temperatures.  Graphite Electrodes Except for vacuum, it can only be used in neutral or reducing atmospheres. 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, extre...
