Graphite crucible formation and types of graphite crucible is in crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, with different kinds of clinker with and made the main application of anti flint graphite crucible smelting special alloy steel, molten non-ferrous metal and alloy. In terms of the performance and use of the product, the graphite crucible is a component of the refractory material. Graphite crucible formation and types of graphite crucible is in crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, with different kinds of clinker with and made the main application in smelting special alloy steel, molten non-ferrous metal and its alloy refractory graphite crucible.…
The carburetant are divided into using in steelmaking and iron casting and some other materials are also need the carburetant , such as the additive in brake pads, as the friction material . Carburetant belongs to the external carbon materials in steel and iron smelting. The high quality carburetant is essential agent additive for production of high quality steel. The carburetant has many kinds of raw materials, the production processes also are different, wood carbon, carbon coal, coke, graphite, etc., it has a lot of small types in the various categories . The high quality carburetant generally refers to the graphitization carburetant,under the condition of high temperature, the carbon atoms are arranged in graphite morphology, so it’s called as graphitization.…
The high purity and high strength graphite are commonly used in nuclear reactor and rocket structure material and the parts and devices required in fabrication of high purity metal, semiconductor materials and rare metal . The high purity graphite used in semiconductor consumption , the high purity graphite used in single crystal furnace, the crucible boat and dish of semiconductor materials smelting and the devices in smelting high pure metal . The impurity content of this kind of graphite material is requested by <0.01%; the bulk density is 1.55 ~1.75g/cm3. Its production process is generally the same compared with ordinary graphite process ,but we must choose the ash content is less than 0.05% of the raw materials for the graphite…
