Introduction 

1. Graphite crucible can be used for non-ferrous metal smelting and casting, dissolving gold

or silver ornaments, analysis of special type steel, sintering hard metal.


2. graphite crucible for smelting gold is specialized in melting gold in headgear and jewelryindustry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles accordingto customer's requirement.


3. Machined from high pure graphite and widely used in the gold,silver,platinum and other noble metal's melting.If it's used in oxygen atmosphere,it wil start to be oxygenized when the temperature is higher than 700-800°c. If it's used in the protective atmosphere, it can stand more than 2000°c.


4. widely used in such fields as industrial furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc.

Q:Graphite can react with alkali in high temperature
Graphite can react with alkali in high temperatureThe chemical properties of graphite are very stable at room temperature and do not react with acids, bases and other substances.
Q:What is the white product in the crucible?
What is the white product in the crucible?
Q:What are the technical specifications of graphite crucibles?
Graphite crucible has the characteristics of high temperature resistance, large volume density, thermal shock resistance, corrosion resistance, acid and alkali corrosion resistance, high efficiency, energy saving, environmental protection, high efficiency, low loss and so on.
Q:What is graphite?
Graphite is a crystalline mineral of carbonaceous elements. Its crystalline framework is hexagonal layered structure. The distance between each network layer is 3.40, and the distance between the carbon atoms in the same network layer is 1.42A.
Q:Graphite electrode, high temperature resistant oxidation coating, formulation technology
Graphite materials synthetic materials under high temperature including graphite electrode, graphite mold and graphite crucible three, these three kinds of materials of graphite under high temperature, the graphite is prone to oxidation combustion reaction, cause the rubber surface material of carbon layer porosity increase and loose structure, influence the service life. Taking the conventional baking process of the ladle as an example, the surface of the carbon containing (graphite) refractory material is produced more than 15mm after being roasted, and the decarburization layer is eroded rapidly after being filled. The majority of graphite crucible using ZS-1021 high temperature resistant sealing coating, the coating with high temperature resistance, Sheng Chi Wei Hua special high temperature solution, temperature can reach 1800 DEG C, can long time open flame barbecue, coating materials with nano scale lamellar structure, good compactness, effectively prevent the diffusion of oxygen at high temperature, the hardness can reach 7-8H and the hardness is higher than the hardness of metals. Zhi Sheng Wei Hua ZS-1021 high temperature resistant coating paint closed dense coating formed on the graphite crucible, with strong anti corrosion resistance, high temperature oxidation, anti discoloration effect, resistant properties. High temperature resistant sealing coating is applied to kiln, graphite, metal and so on. At the high temperature, the oxidation rate can reach more than 80%, and the energy saving efficiency of graphite crucible material can reach more than 95%.
Q:In the melting of aluminum alloys, what is the frequency furnace and the crucible type furnace? I heard that the frequency furnace power is lower, faster and more power saving
Medium frequency electric furnace will save a lot of electricity. Medium frequency electric furnace is also placed inside the graphite crucible, copper melting.The last time I saw a foundry over there in Anhui, where the crucible was used to smelt copper, the three or four furnace had to be replaced with a crucible.
Q:Why can't a f containing compound be used in a porcelain crucible, a Lilac Garden?
The F containing compound can not be used in the ceramic crucible for combustion and drying. The main reason is that the corrosion of fluorine on porcelain at high temperature.
Q:Are carbon and graphite widely used? What fields are they applied to?
Isostatic graphite is manufacturing single crystal furnace, continuous casting mould, metal graphite EDM with graphite telegraph irreplaceable materials, is making a rocket nozzle, graphite reactor deceleration materials and reflecting materials excellent material.
Q:Application of graphite in glass production
The main function is:1: to prevent the glass liquid and refractory material bonding.2: prevents the tin liquid unnecessary convection.
Q:Corundum crucible and graphite crucibleSome enterprises use graphite crucibles in vacuum furnaces, while some larger ones use corundum crucibles. What I want to know is the advantages and disadvantages of corundum crucibles and graphite crucibles
Corundum temperature limited, easily cracked at high temperature. But the chemical stability is good, do not use under vacuum. In contrast, corundum is much cheaper.
