  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 ...

  Graphite Electrodes wholesale (1)  Electric Arc Furnace Graphite Electrodes Electric furnace steelmaking is a large user of graphite electrodes. China's electric furnace steel output accounts for about 18% of crude steel output, and  Graphite Electrodes  for steelmaking account for 70% to 80% of the total amount of Sinometal   graphite electrodes . Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace and uses high-temperature heat sources generated by the arc between the electrode end and the charge to perform smelting. (2) Used in mineral heat electric furnace The mineral thermal electric furnace is mainly used for the production of industrial silicon and yellow phosphorus. Its characteristics are that the lower part of the conductive electrode is buried in the charge, an arc is formed in the material layer, and the heat is emitted by the heat of the resistance of the charge, which requires current. Graphite electrodes ...

  Graphite Electrodes for sale   Sinometal Metallurgical Graphite Electrodes  refers to a kind of refractory made of petroleum coke and pitch coke as aggregates and coal tar as a binder. High-temperature graphite conductive material. Wholesale Graphite electrode  is mainly made of petroleum coke and needle coke, coal tar is used as a binder, and it is made by calcining, batching, kneading, pressing, roasting, graphitization and machining. The conductors that heat and melt the furnace charge can be divided into ordinary power graphite electrodes,  high power graphite electrodes  and ultra high power graphite electrodes according to their quality indicators. The main raw material for graphite electrode production is petroleum coke. A small amount of pitch coke can be added to ordinary power graphite electrodes. The sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also required when producing high-power or ultra-high-power gra...

  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...
