Can Graphite Electrodes be Used Directly Under Humid Conditions?

 As an HP Graphite Electrodes Manufacturer, share with you. Graphite as electrode: mainly use petroleum coke and needle coke as raw materials, coal tar pitch as binding agent, made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It is an electric arc model in an electric arc furnace The form can release electric energy to control the structure of the furnace charge, heating and melting the conductor, according to its quality management index level, can be divided into a normal user power, high power and high power. Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in an electric arc furnace. The conductors used for heating and melting the charge can be classified into ordinary power, high power and ultra-high power according to their quality indicators.

Graphite Electrodes

Graphite electrodes mainly include four types of ordinary power graphite electrodes, anti-oxidation coating graphite electrodes, high power graphite electrodes and ultra-high power 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 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. 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.

The main content of the graphite electrode system includes four types of corporate normal working power graphite electrodes, anti-oxidation active coatings with graphite electrodes, high-power graphite electrodes and high-power graphite electrodes. When using and some special education products, we must ensure that these technical products have a very good environment when they are used, so that good teaching effects can be obtained. If the graphite electrode gets damp, then China cannot continue to work on the use of graphite electrodes. When we use some high-purity graphite, if these products get damp, it will directly affect our use effect.

We cannot use these products directly.

If we want these products to have a good use effect, then we must ensure that these products have good drying properties, so that we can use a good guarantee. If Graphite Electrodes gets damp, then you need to go through a special process so that it can make these products have good results when used.

What are Graphite Electrodes and Needle Coke?

图片
  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...
