Production Of Graphite Crucible. Emerging Business Investment Opportunities.

Production of Graphite Crucible. Emerging Business Investment Opportunities. A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot. Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals.

Applications Lubrication Refractories Foundry Battery Production Others Features: We offer graphite crucibles for varied purposes High density graphite crucibles are utilized in vacuum Inert atmosphere furnaces Best suited crucibles for quality melting High thermal conductivity Heat shock resistance: Graphite crucible is strong, it can withstand high temperatures. High heat resistance Corrosion resistance Oxidation resistance Anti-adhesion Resistance to slag remover Acid resistance Use of Graphite Crucible Graphite crucible is widely used for experiment and the melting of metals, graphite crucible material with special of high purity, high strength, high density graphite material; through high precision CNC machining equipment, can be machined graphite crucible, graphite casting crucible, graphite oil groove, slide, drawing tablets, pull rod of mould graphite products. Graphite crucible for smelting noble metals selected special graphite materials can make the graphite crucible product 2 times more than ordinary materials product durability, longer service life, more can withstand more than 2000°C high temperature! Graphite crucible features: 1 good thermal stability of graphite crucible: for the use of graphite crucible quench. 2 graphite crucible good corrosion resistance, impact resistance, in order to ensure the reliability of product quality. 3 graphite crucible, good resistance to acid and alkali. 4 good heat conduction performance of graphite crucible: it can greatly shorten the smelting time, save energy. 5 the ash of the graphite crucible is less than 300pp, so that the precious metal is not polluted in the smelting process. Mainly used in auto parts, electronics and new materials industry, graphite crucible is melting and holding non-ferrous metals and new materials resistant containers. Can also be used in the refining and purification of nonferrous metals and new materials. For the benefit of environmental protection, the international efforts to improve the weight of light metals in industrial products. Therefore, aluminium, magnesium, zinc and its alloys are widely used in the production of automobile, motorcycle and electronic products. If the engine cylinder cover die-casting production of automobile and motorcycle wheels, engine, brakes, air filter, piston, a radiator, a direction plate skeleton and electronic products in the mobile phone shell. Manufacturing process of graphite crucible During the sintering process of graphite crucibles, the organizational structure of the green body has a series of changes, the changing part is mainly the plastic refractory clay. The basic process of the crucible sintering can be divided into the following four stages to illustrate: Preheating and baking stage. The temperature at 100~300 degrees, it is the process of graphite crucibles exclude residual moisture. The heating speed should slow and the kiln roof should be open, it should control the temperature strictly especially when the graphite crucibles in the residual moisture content exceeds 3%, otherwise the crucibles will have the crack and it maybe explode. Low temperature firing stage: 400-600? is the Low temperature stage of sintering of the graphite crucible. With the increase of the temperature of the kiln, the combination water in the crucible begins to decompose and remove. the main composition in clay are Al2O3 and SiO2, once formed, they are in the free state, the glaze layer of crucible surface has not yet melted, heating speed should be still slow, if the heating speed is too fast and uneven, it also prone to explode and the collapse of the crucible bing . Mesothermal sintering stage: 700-900? is the Mesothermal sintering stage of graphite crucible. At this time, the amorphous Al2O3 in clay may be partially converted into y crystalline Al2O3 when the kiln temperature gradually increased, the Al2O3 and Si0'exist in the Free State form hard silicate cured material, it connect the graphite and clinker in crucible and then solidified into a whole. In the medium temperature sintering process, the surface glaze layer in graphite crucible melt with the increasing of temperature gradually and form a layer of glass like glaze film, enclosed or covered on the surface of the crucible, it protect the crucible from oxidation. During this period, it is better to heat up quickly and the original flame should be good in the kiln. High temperature firing stage: The temperature of this stage temperature is iooo-1200cc. The clay in graphite crucible after sintering in the medium temperature form curing, gradually transformed into mullite, such as 3A1203+2Si07:3Al203'2Si0. (Mullite). During this period, the heating rate should be faster than in the middle temperature (commonly known as the fire process), the furnace flame should be controlled in the neutral flame or reducing flame. The glaze layer has been completely melted during the crucible in high temperature sintering process, forming a glass like glaze film, close to the crucible surface. If the temperature exceeds the maximum temperature limit of sintering glaze, it easily cause the oxidation of the crucible. Therefore, in the high temperature sintering process, we should observe the glaze layer melting condition of graphite crucible and avoid the burnt and not up to the sintering. Mullite (3A1203'2Si02), a senior Department of physical and chemical properties of refractory minerals and a stable. The density, hardness, refractoriness and softening point are very high, low coefficient of thermal expansion. In the structure of the crucible, it is an important role of consolidation and hardening. It can be known that, in the crucible sintering process, due to the thermal effect of plastic refractory clay, the consolidation of graphite and clinker has a certain mechanical strength. Therefore, high and low of the sintering temperature, temperature control in the process of operation, it will has an important influence to the quality and service life of graphite crucible products. Market Outlook The global graphite market was valued at $14.3 billion in 2019, and is expected to reach $21.6 billion by 2027, registering a CAGR of 5.3% from 2020 to 2027. By type, the synthetic graphite segment holds the largest market share, owing to increase in demand from the steel and battery industry. This increase in demand from the steel and battery manufacturing industry is attributed to increase in use of graphite electrode. Synthetic graphite is expected to maintain its dominance during the forecast period. Graphite crucibles are widely used in experiments and for melting metals through high precision CNC machining equipment. Graphite crucibles of high purity, high density, and high strength are used in these applications. Growth of the foundry industry is a major factor driving the graphite crucibles market. A growing industrial sector coupled with the increasing need for specialized metal and alloy castings is expected to enhance the demand for graphite crucibles during the forecast period. As per an assessment, 8.5% growth in foundry and casting industry is estimated across the globe. Therefore, the use of graphite crucibles is expected to increase accordingly. Development of modern small scale industries and positive outlook of the special casting metallurgical industry in countries in Asia Pacific is further estimated to drive the graphite crucibles market in the next few years Graphite crucibles can withstand high temperature, and have good resistance to chemical erosions and thermal shock. Graphite crucible is ideal especially for the melting of aluminum, copper, and other metals. Availably of various alternatives such as ceramic crucibles, and platinum crucibles, used in casting, metallurgy, and machineries is expected to hamper the market growth in the near future.
