　　All materials using isostatic isotropic, high strength, high-density high pure graphite.Products include high pure graphite crucible, graphite slide mold, graphite casting mold and all kinds of graphite special-shaped mold products manufactured by the high purity graphite, superior performance.

　　The following characteristics of the graphite crucible:

　　1 Thermal Stability: the use of the graphite crucible in the rapid cooling of the hot and cold conditions, specially designed to ensure the reliability of product quality.

　　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 regulate. The arc temperature of the arc furnace is as high as 3000 to 6000 degrees, and the furnace temperature is above 2000 C, which is much higher than that required by smelting the general steel. It can be used for smelting alloy steel and stainless steel which can not be smelted by converter.

　　The atmosphere in the furnace is easy to control and adjust. In the different stages of the smelting furnace, it can not only cause the oxidizing atmosphere, but also can cause the reducing atmosphere, the former is conducive to carbon and phosphorus, which is in favor of deoxidation, desulfurization, oxidation, recovery of alloying metal elements and control liquid steel composition. The electric furnace equipment is simple, the investment is few, the construction plant is fast, the area is less, and it is easy to control the pollution.

　　But due to the high temperature energy generated by the electrode in the short circuit to provide large power consumption, power consumption of about 350-600kwh smelting 1 tons; high hydrogen and nitrogen content in finished steel. Because under the action of the arc, the water vapor of the air in the furnace is dissociated, the hydrogen and nitrogen generated, such as entering the molten steel, will affect the quality of the steel. The arc is a "point" heat source, and the temperature distribution in the furnace is uneven. When the pool is calm, the temperature of each part of the molten steel is quite different. The existence of carbon electrode will increase the carbon of molten steel, which makes it difficult to smelt low carbon steel.

　　Waste steel is a kind of energy - carrying resource, and the use of scrap steel can save a lot of energy. In large iron and steel complex, mining, mineral processing, sintering, coking, iron making, steelmaking and rolling, energy consumption and pollution emissions are mainly concentrated before steelmaking process. The study shows that the energy saving is 60%, and the water saving is 40%.

　　Scrap steel is also an environmental resource. Compared with steelmaking with iron ore, the waste steel can be reduced by 86%, 76% and 97%, which is conducive to cleaner production and waste reduction.

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, it keeps all kinds of physical and chemical properties of the natural graphite. That is to say, it has good thermal conductivity and high temperature resistance, and the thermal expansion coefficient is small in the process of high temperature application, and it has a certain anti strain property to the rapid heating and rapid cooling. The corrosion resistance of acid and alkaline solution is strong, and it has excellent chemical stability.

　　The graphite crucible has many types and specifications, and it is not limited by the production scale, batch size and smelting material variety when we use them. It can be chosen arbitrarily, and it has strong applicability and can ensure the purity of the melted material.

　　Graphite crucible is widely used in smelting of alloy tool steel and the smelting of nonferrous metals and their alloys and it has better technical and economic effects because of their excellent properties.

　　The production materials of graphite crucible can be summarized into three types. The first is crystalline natural graphite, the second is plastic refractory clay, and the third is calcined hard kaolin skeleton clinker. In recent years, the high temperature resistant synthetic materials such as silicon carbide, alumina, carborundum and ferrosilicon have been used as the framework clinker. This kind of clinker has remarkable effect on improving the quality of crucible product, enhancing the density and mechanical strength of crucible.

　　There are three kinds of forming methods for graphite crucible which are hand molding,the rotary plastic forming method and the pressing forming method

　　Today, let's talk about the surface treatment technology of the graphite mold

　　In addition to the reasonable matching of the strength and toughness of the matrix, the surface performance of graphite mold is very important for the working performance and service life of the graphite mould. The surface treatment technology of graphite mould is a systematic engineering to change the surface morphology, chemical composition, structure and stress state of graphite mould by surface coating, surface modification or compound treatment technology, so as to get the required surface properties. At present, the main application of the graphite mold manufacturing is nitriding, carburizing and sclerosing film deposition.

　　Because the surface nitriding technology can form good performance, and the quenching process of nitriding process and graphite mold steel have good coordination, at the same time, the nitriding temperature is low, without intense cooling after nitriding deformation of tiny graphite mold, so the surface of graphite mould is used to strengthen permeability nitrogen technology is the most widely used earlier.

　　Graphite mold carburizing is to improve the overall toughness of the graphite mold, that is, the working surface of the graphite mold has high strength and wears resistance. The hardened film deposition technology is now more mature than CVD and PVD. The graphite mold has been applied to the coating hardening film since 80s last century. The current technical conditions, the hardening film deposition techniques (mainly equipment) the high cost is only applied in some precision, long-life graphite mold, if the establishment of heat treatment center, then coated with hardened film will significantly reduce the cost, more Shi Momo out if using this technology, can improve the overall graphite mould of China's manufacturing level.

　　Because graphite has many excellent properties, it has been widely used in metallurgical, mechanical, electrical, chemical, textile, national defense and other industrial sectors. Molding and manufacturing graphite crucible refractory and related products, with high fire resistance, low thermal expansion, metal smelting process, by metal infiltration and erosion are stable under high temperature, good thermal shock resistance and excellent thermal conductivity, so the graphite crucible and a graphite products are widely used in the process of direct the molten metal in the.
