 Magnesia-Carbon Brick wholesale

Magnesia-Carbon Brick China 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.

Sinometal 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, wholesale magnesia-carbon brick effectively utilizes magnesia's strong resistance to slag erosion, carbon's high thermal conductivity and low expansion, and compensates for the biggest shortcomings of poor resistance to magnesia.

The main features are: good high temperature resistance, strong slag resistance, good thermal shock resistance, and low high temperature creep.

The traditional magnesia-carbon bricks made with a synthetic tar binder according to the cold mixing process harden and acquire the necessary strength during the tar damage process, thus forming isotropic glassy carbon. This kind of carbon does not show thermoplasticity, which can relieve a large amount of stress in a timely manner during baking or operation of the lining. The magnesia-carbon brick produced with the asphalt binder has a high temperature plasticity due to the formation of an anisotropic graphitized coke structure during the asphalt carbonization process.

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...
