Electric arc heat is mainly used in electric furnace steelmaking, and the temperature is up to 4000 degrees centigrade in the arc action area. Smelting process is generally divided into melting stage, oxidation stage and reduction stage. In the furnace, it can not only cause oxidation atmosphere, but also cause reduction atmosphere, so the efficiency of dephosphorization and desulfurization is very high. The main materials used for iron are scrap steel, accounting for about 70%, in addition to the addition of molten iron, pig iron, direct reduction iron, hot pressing block and so on. The smelting time is longer, at least two times as much as the converter's smelting time. The furnace temperature is high and easy to control and…

We have various of graphite rods and blocks in different grades such as isostatic graphite, molded graphite,extruded graphite,vibrating graphite. Isostatic graphite rods and blocks are widely used in medical treatment, metallurgy, chemical, airspace, and other industries, etc.We can provide different specification quality isostatic graphite rods: non-standard sizes can be designed and manufactured as per drawings or sample;high temperature and oxidation resistance, corrosion resistance, longevity;It is widely used in hot mineral and metallurgical and chemical industries. The properties of the fine grain graphite rod and block:fine grain,homogeneous structure, high density,excellent thermal conductivity;high mechanical strength;proper electrical conductivity;minimum wet tability to molten metals. The high purity graphite means fine texture ,high purity-strength-density graphite products using the fine quality coke (low ash content) as…

Graphite crucible is a kind of refractory graphite crucible which is made of crystalline natural graphite as main material, plastic refractory clay as the binder, and with different types of clinker. It is mainly used for smelting special alloy steel, melting non-ferrous metals and their alloys. Graphite crucibles are an integral part of refractories materials according to its properties and application. In graphite crucible, there are three kinds of common graphite crucible and special allotypic graphite crucible and high purity graphite crucible. Different types of graphite crucibles are different from raw materials, production methods, process technology and product type specifications due to their different performances, application and conditions. The main raw material of graphite crucible is crystalline natural graphite. Therefore,…
