  As a   Graphite Electrodes Supplier , share with you. Graphite bearings use graphite as the main substrate in graphite products. They have strong self-lubricating properties and corrosion resistance. They cannot use lubricating oil for a long time, and are mostly used in sliding bearings. Graphite rods are commonly used in electric heaters of 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 atmosphere or a reducing atmosphere. It has a small thermal expansion coefficient, a large thermal conductivity, a resistivity of (8~13)×10-6 Ω·m, better workability than SiC and MoSi2 rods, high temperature resistance, excellent cold and extreme heat resistance, and price Cheaper. The graphite electrode is mainly made of petroleum coke and needle coke as raw materials, and coal pitch as a binder. It is made by calcination, batching, kneading, pressing, roas...

  As a   Graphite Electrodes Manufacturer , share with the answers and answers. The graphite electrode is a high temperature resistant graphite conductive material made of petroleum coke, pitch coke as aggregate, coal pitch as binder, calcined, crushed and ground, batching, kneading, forming, roasting, dipping, graphitization and processing . It is different from the natural graphite electrode prepared with natural graphite as raw material. Choosing the appropriate graphite electrode material, we all know that graphite has the characteristics of other metal materials that cannot be replaced. Because of the choice of materials, the actual choice of   Graphite Electrodes   is often a feature that many people are confused. The selection of materials is based on graphite electrodes, and there are many. Graphite Electrodes 1. End consumption Including the sublimation of graphite material caused by arc high temperature and the loss of chemical reaction between the electrod...

  As an   Alumina Magnesia Carbon Brick Manufacturer , share with you. Magnesia-Carbon Brick  uses high melting point basic oxide magnesium oxide (melting point 2800°C) and high melting point carbon material that is difficult to be infiltrated by slag as raw materials, adding various non-oxide additives. Non-burning carbon composite refractory material combined with carbon binder. Magnesia-Carbon Brick Effect Magnesia carbon bricks are made of high melting point basic oxide magnesium oxide (melting point 2800°C) and high melting point carbon materials that are difficult to be infiltrated by slag as raw materials, adding various non-oxide additives. Non-burning carbon composite refractories combined with carbon binder. Magnesia carbon bricks are mainly used in the lining of converter, AC arc furnace, DC arc furnace, slag line of ladle and other parts. As a composite refractory material, magnesia-carbon brick effectively utilizes magnesia's strong resistance to slag erosion...

  As a   Graphite Electrodes Supplier , share with you. With the continuous development of China's high-tech technology in today's society, the application of graphite molds in people's daily life is very common in order to improve the efficiency of his application. How do people improve the use of graphite molds in China What about the period? Graphite Electrodes 1. The method used for manufacturing graphite molds should be used in the manufacturing process of cutting to improve the smoothness of the surface of the graphite mold, using metallic materials to reduce adhesion and level of fusion between high purity graphite. Graphite rods are commonly used in electric heaters of 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 atmosphere or a reducing atmosphere. It has a small thermal expansion coefficient, a large thermal conductivity, a resis...

With the improvement of domestic epidemic prevention and control, resumption of work, resumption of production, and resumption of school are proceeding in an orderly manner. However, foreign countries have ushered in the outbreak of the epidemic. Many countries began to lack medical protective substances and ventilators. Under the situation of China's epidemic situation stabilizing, countries began to rush to order medical supplies produced in China.  Non-Invasive Ventilator COVID-19 is an acute respiratory tract infection disease. At present, there is no clinical or medical means to cure it, but the ventilator plays an important role in the treatment of COVID-19. So, let's take a look at what is a ventilator, and what role does the ventilator play in the treatment of new coronary pneumonia? What is a ventilator? Non-Invasive Ventilator  is an effective method that can artificially replace the autonomous ventilation function. It has been widely used in respiratory f...
