Product Description

 

Specifications for Graphite Silicon Carbide Crucible For Aluminum Melting :

1.Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure.

2.High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity.

3.New-style materials: new heat conduction material ensures faster heat conductivity and pollution-free product, reduces adherent slag.

4.Resistance to corrosion:better anti-corrosion than normal clay-crucible.

5.Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime.

6.High-strength: high-density body and logical structure make the product better compression property.

7.Eco-friendly: energy-efficient and pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment.

8.Multi-function: Can be used in induction graphite crucible furnace

Physicochemical Properties of graphite crucible:

 

The crucible is an utensil or melting tank vessels that is made of refractory material (such as clay, graphite, quartz or difficult molten metal iron, etc.).

Graphite crucible, with is special advantages and Plasticity, is widely used in the smelting area, e.g. gold smelting, silver smelting, aluminum smelting, cooper smelting, etc.

Q:Why do laboratory crucibles use ceramics instead of glass?
The ceramic crucible does not soften and can withstand alkaline material.
Q:Use the tripod why use mud, and mud and three foot tripod supporting in the use of the crucible?
Otherwise, the three foot above the ring hole is too large, directly on the crucible to fall down.
Q:To sum up the different uses (and causes) of various crucibles in ChemistryQuartz glass crucibles, for examplealumina crucibleGlass crucibles, iron crucibles, and the like are different and should be noted
Molten material with acid as flux (such as K2S, 207, etc.)Porcelain crucible: 1., heat resistance of about 1200 degrees2. suitable for K2S207 and other acidic substances melting samples3. generally can not be used for Na0H, Na202, Na2CO3 and other alkaline substances for melting flux, so as not to corrode the porcelain crucible. Porcelain crucible can not be contacted with hydrofluoric acid4. porcelain crucible can be diluted HCl boiling cleaningIron Crucible: iron does not react with sodium hydroxide, iron crucible can melt caustic soda, and iron crucible is used at 400 degrees or more. It is not economical, even if it is not melted, it also oxidizes rapidlyGraphite crucible: universal type graphite crucible and graphite crucible shaped and high pure graphite crucible three. Graphite crucible of various types, due to performance, and the use of different conditions, the raw material used, production method, technology and product specifications are different. Shi Mogan Guo is the main raw material, is the crystallization of natural shape it is graphite. It maintains the physicochemical properties of all kinds of natural right. That is: the original ink has good thermal conductivity and high temperature resistance, high temperature in use process, small thermal expansion coefficient, thermal quenching of, has a certain anti strain properties. The acid alkali solution, the corrosion resistance is strong, excellent chemical stability. The graphite crucible, because has more excellent performance, so in casting, metallurgy, machinery, chemical and other industrial sectors, is widely used for smelting alloy tool steel and non-ferrous metal and alloy smelting and has good. Technical and economic results
Q:Melting the iron in the graphite crucible. Does the graphite in the crucible turn into carbon and it melts into the steel?
Graphite is a very pure substance, and graphite is a transition crystal. The carbon atoms in each layer of graphite are bonded by non-polar covalent bonds, and the molecular layers of graphite are joined by intermolecular forces. The melting point of the graphite crucible is 3652 to 3697 degrees (sublimation), so the graphite crucible is high temperature resistant.
Q:Medium frequency furnace plus graphite crucible does not start
If the furnace does not start, that the magnetic induction coil is touched, because the graphite graphite crucible and conduct electricity, may be you do not match the intermediate frequency furnace
Q:What is the difference between the indirect method Zinc Oxide and the direct law Zinc Oxide?
Indirect material method of Zinc Oxide is obtained through smelting metal ingots or zinc. Zinc in high temperature graphite crucible at 1000 DEG C converted to zinc vapor, air oxidation of Zinc Oxide before being fed into, and Zinc Oxide collected particles in the cooling pipe. The indirect method is in 1844 by the French scientist Leclair (LeClaire) promotion, also known as the French law. Indirect technology produced by Zinc Oxide is simple and the cost is impacted by raw materials greatly. Zinc Oxide particle indirect method of production with a diameter of 0.1-10 microns, the purity of 99.5%-99.7%. According to the total volume, the indirect method is the main method of production of Zinc Oxide.
Q:What are the uses of graphite crucibles?
Therefore, aluminum, magnesium, zinc and their alloys are widely used in the manufacture of automobiles, motorcycles and electronic products. Such as die-casting production automobile and motorcycle wheel hub, engine cylinder head, brake, air filter, piston, radiator, steering wheel frame, and electronic products in the mobile phone shell, etc..
Q:New energy, crystal, silicon and other research and development, production, because the crucible rotary table heating device, there is no good solution to share?
1. features:(1) according to the actual shape and size design, including 3 dimensional geometry to meet your equipment.(2) provide heater longer moisture antichemical silicone rubber material.(3) simple paste and touch on your parts, through vulcanization, adhesives, or fasten pieces, etc..
Q:Why are there too many impurities in the gravity casting products of aluminum alloy, so they can not be welded well by argon arc welding?
The filter is not added in the casting process, some slag ran in, leading to the casting surface or internal slag, leakage or air pressure testing, due to impurities, argon arc welding welding is up to where there is always staying, not fusion. The solution, first of all to choose high purity aluminum ingots, some rural plant products do not choose, are turning or cutting scrap materials in investment, not too many impurities; secondly in the casting process, increase to two times to minimize the filtering impurities.
Q:What is the porcelain crucible with a small hole under it?
Is the crucible, crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, refractory graphite crucible with different types of clinker with which is mainly used in smelting special alloy steel, nonferrous metals and alloy melting. Graphite crucibles are an integral part of refractories in terms of their properties and uses.
