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:What crucible can be used to make steel? At least 1500 degrees resistant
A graphite crucible is a very important purpose is to iron and steel. The oxidant using this process is oxygen. The air is blown into the molten iron, the impurity of silicon and manganese oxide. The release of large amounts of heat in the oxidation process (including 1% silicon iron can make the temperature rise of 200 Celsius), can make the furnace reach a high enough temperature. So the converter does not need the additional use of fuel.
Q:What are the catalysts for making SiC from rice husk?
The rice husk is crushed, in the temperature range of 650 to 700 DEG C, the carbonization process in furnace will be closed after the first rice husk carbonization catalyst, according to a certain weight ratio and adding, evenly mixed, the mixture is filled in the graphite crucible, the carbon fiber arranged on the upper part of the mixture, cover crucible cover. The graphite crucible is placed in a vertical vacuum furnace with graphite as the heater, and argon gas is used to protect the silicon carbide whisker on the carbon fiber. The invention realizes the automatic separation of whisker and powder, and the whisker is attached to the upper part of the carbon fiber in the powder material, and does not need to be separated from the residual carbon or other powder for two times. The obtained whisker has a high direct crystal rate and a simple process.
Q:Is graphite crucible resistant to hydrofluoric acid?
Mainly depends on the use of working conditions, the use of air, then more than 600 degrees Celsius will begin to be oxidized, and the service life will not be long.
Q:Which crucibles are available for melting sodium hydroxide?
Graphite crucibles and metal crucibles can be usedA porcelain crucible can not be used because of its silicate content, which reacts with NaOH and damages it.
Q:How do you see the conch alive?
In addition, the observation of soft tissue part of the edge of sharp, color distinct, if the edge of the round blunt, pale color, basically dead, alive in time, not fresh
Q:What are the advantages of a graphite furnace atomizer compared to a flame atomizer?
Flame atomizer: it consists of three parts: sprayer, premixing chamber and burner. Features: easy operation and good reproducibility.
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
Graphite crucible is a high temperature resistant and difficult to sinter material. But the biggest problem must be used in vacuum or reducing atmosphere. Otherwise, graphite is easily oxidized at high temperature. Moreover, this crucible is more expensive
Q:Does the graphite pan need preheating?
5. the use of coke block size is less than the furnace wall and the crucible spacing should be added since the 5 fall, not ramming.6. crucible before use for 1-1.5 hours from the gas warm up to 200 degrees Celsius (especially in the initial drying must be in a continuous turning of the crucible and the crucible, slowly warming up and down at the same time and shall not exceed 100 degrees, to be slightly cooler, water vapor discharged after 1 hours) and then continue to heat up. The temperature to about 800 DEG C, baking time not too long. (such as spalling, improper preheating burst, not a quality problem, if the company is not responsible for the return. 7.) must keep the inside wall intact, to avoid bias by.8. flame burner flame heating, don't direct injection in the crucible, should be sprayed on the seat and into the crucible.9. proposed to use.10. into the metal crucible clamp corresponding to the bottom and then insert the scrap metal ingot, but not too close to the edge and, in order to avoid fragmentation through the use of a.11. crucible crucible best due to the expansion of metal Continuous melting, reduce the interval time.12. if intermediate stop using the remaining liquid should be dry, in order to avoid cracking caused by the continued use of.13. in the smelting process, must strictly control the amount of refining agent, added in excess, will reduce the service life of the crucible. And often clean ballast junction, guide and capacity to change the face of the impact of free crucible at the same time. Ballast too thick will cause the upper expansion.
Q:Which is a good quality graphite crucible?
The ordinary graphite crucible can not guarantee the safety in the high temperature environment, moreover, the conduction speed is slow in the test, which is not good for the experiment.
Q:Graphite is widely used in industry and in daily life. It can not be used in industry
A mold of a glass, made of graphite material, a porcelain boat for press and sintering, and a crystal growth crucible for monocrystalline silicon.Graphite material as a power reduction material in an atomic energy reactor.Graphite powder (4~5 grams per ton of water) can prevent boiler surface scaling. In addition, graphite can be applied to metal chimneys, roofs, bridges and pipelines to protect against corrosion and rust.Graphite can be used as a pencil core, pigment, polishing agent.Graphite gradually replaces copper as the preferred material for EDM electrodes.
