Super Quality Long Working Life SiC Graphite Crucibles

 

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:Rotary kiln dust removal, zinc coated sand and Zinc Oxide Technology
These are the skills of an enterprise, and nobody will say that.
Q:The graphite boat loading and loading real real graphite boat is what?
The graphite boat used for solar energy industry and real loading: PECVD carrying vehicles, loaded from silicon, preparation of middle and high efficiency filter, ensure that blows air purifying requirements.
Q:What are the welding methods at the end of the thermocouple?
Salt welding type K thermocouple in the beaker into the sodium chloride solution into the platinum wire in aqueous solution as an electrode, and the electrode heat as another electrode. When soldering, contact the top of the thermocouple with the solution slightly, switch on the power supply and switch off the power quickly after the arc is started. This welding method is suitable for welding 0.03mm-0.3mm thermocouples with finer welding diameter.
Q:What graphite crucible is used to smelt aluminium by electromagnetic induction heating?
Electromagnetic induction heating is the heating of graphite, and can soon rise to 1000 degrees, but aluminum is a magnetic material, will block the electromagnetic field, so this scheme is not feasible
Q:Why is graphite crucible smelting reducing properties of the burden is particularly vulnerable to corrosion?
Corrosion, the nature of the general graphite is extremely stable, it is difficult to corrosion, but some special organic substances, such as resin at low temperatures, will be able to graphite erosion, making the graphite due to mechanical strength and damage. And some oxygenated compounds, too.
Q:What magnetic material is sintered with large corundum crucible?
The graphite crucible is a high temperature resistant and difficult to sinter material, but the biggest problem must be used in a vacuum or a reducing atmosphere. Otherwise, graphite is easily oxidized at high temperature. And the crucibles are more expensive.
Q:How to maintain the graphite crucible?
In this way, the graphite crucible can not be used when the graphite crucible is used, and the residue left in the graphite crucible is damaged by the graphite crucible itself
Q:Single crystal furnace quartz crucible cast 22 inch 175 kilograms of feed it
Back chaos, in fact we are very worried about the recovery of this material strength and composition by crucible crucible change can not be used, but also fast, so the results will soon be out.
Q:What are the advantages of a smelting furnace using induction heating, and will it reduce costs?
On the surface of the electromagnetic oven if made of metal material, the use of the electromagnetic oven, the upper surface of the material to the loss of power electromagnetic induction, electromagnetic oven on the surface to be made from insulating material, the heating part is at the bottom of the pot, right A;
Q:I'd like to smelt 104 aluminium alloy by medium frequency furnace. What should I pay attention to? Please point it out, thank you!
Don't know what is your crucible material medium frequency furnace, if using graphite crucible, graphite as easily broken and easy to absorb moisture, must be handled with care to avoid the collision, but must be in use before the slow heating and drying, until the crucible to dark red, check no cracks can be put into the molten alloy. If the iron crucible, the Aluminum Alloy are strictly limited, so the iron, iron crucible, Tieshao, ladle, the tool must be coated with paint, paint is selling goods, components do not know, iron crucible and apparatus must also be preheated, exclusion of moisture. In addition, do not know you are refining aluminum ingot or making ah Aluminum Alloy parts, if the production parts should pay attention to defects of oxidation, slag and coarse grain, I am afraid that refining, refining agent are also ready to sell goods, how can read the instructions. Especially when smelting Caution!, preventing aluminum liquid splash, including many contents, such as inspection and testing, there is not much to say, the main note in the smelting process I thought so much, typing is slow, very hard ah, hey. Hope to be of some help to you.
