SiC Graphite Crucibles For Melting Aluminium And Copper, Brass                              

 

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

Q:What are the properties of diamond, graphite and charcoal? What is the relationship between the nature of the material and its use?
Because of the refraction and scattering of light by diamond, it can be used as decoration. Graphite is soft to be used as pencil core;
Q:How to extract pure silver from sundry Silver
In a dilute nitric acid solution of 10% concentration, silver reacts with nitric acid to produce silver nitrate.300 kg. This dilute nitric acid solution can treat 4000 kilograms of silver glass and become silver nitrate solution
Q:What are the components of a pencil core?
Graphite is an allotrope of elemental carbon around each carbon atom attached to three other carbon atoms arranged in a plurality of hexagonal honeycomb, each layer between the Fan Dehua gravitational weak. Since each atom emits an electron, the electrons are free to move, so the graphite belongs to the conductor. Graphite is one of the most soft mineral, opaque and feel greasy, color from black to gray iron, the shape of a crystal, thin, squamous, striped, layered or scattered in the metamorphic rocks. Chemical properties are inert and corrosion resistant.
Q:What is the main function of graphite?
As refractory material: graphite and its products have the properties of high temperature resistance and high strength. They are mainly used in the metallurgical industry to make graphite crucibles. In the process of steelmaking, graphite is often used as a protective agent for steel ingots and lining of metallurgical furnaces.
Q:How to calculate the loss of aluminum slag melting?
Look at the size of aluminum slag, big saw recovery rate is high, small saw fine chip is low.
Q:Graphite is widely used in industry and in daily life. It can not be used in industry
General graphite in industry and daily life has been used in various fields, but the graphite can not be used by those who industry is a matter to be determined, so we can only go to research specific, what is the specific application of graphite materials, if you don't want to in the industry application of graphite material
Q:The biggest problem with graphite crucibles must be to use in a vacuum or a reducing atmosphere
Reducing atmosphere is in such as crucible with coke and he is using a principle that because the air has been burning up!
Q:Aluminum graphite crucible for iron crucible which is good
The graphite crucible can be heated by coke, and now the graphite crucible is faster than the iron crucible and higher than the iron crucible. If it is graphite crucible used in electric furnace, some manufacturers use it for about one year.
Q:How long can a graphite crucible last for a long time?
The special thermal shock resistance, thermal expansion of graphite is anisotropic, and the macro expansion coefficient is small, the temperature change under the condition that the volume change of graphite is not large, coupled with its good thermal conductivity, good thermal shock resistance and graphite.
Q:What are the uses of graphite? What are the downstream products of graphite?
As refractory material: graphite and its products have the properties of high temperature resistance and high strength. They are mainly used in the metallurgical industry to make graphite crucibles. In the process of steelmaking, graphite is often used as a protective agent for steel ingots and lining of metallurgical furnaces
