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:Can the graphite crucible be rinsed with water?
Graphite crucibles can be rinsed with water. The graphite crucible will burst when heated.
Q:Help: how can the graphite crucible be heated to 1000 degrees?
The fastest speed is the electromagnetic heating
Q:How to break 40 low carbon steel smelting
Only by argon arc welding in small diameter pipes, piping, is a commonly used method for ITU argon welding section, then replace the consumption of electrode for welding wire, ultra low carbon in the coefficient multiplied by 1.15.
Q:How to reduce the degree of oxidation of graphite when sintering at high temperature?
(1) reasonable furnace geometry and feeding order;
Q:What is the porcelain crucible with a small hole under it?
The crucible can be divided into three categories: graphite crucible, clay crucible and metal crucible. In the graphite crucible, there are three kinds of universal graphite crucible and special graphite crucible and high-purity graphite crucible. Various types of graphite crucibles, because of their performance, application and application conditions, are different in raw materials, production methods, process technology and product models and specifications.
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:Why does China choose quartz crucible directly in the aspect of Czochralski silicon?
The oxygen in the quartz crucible can not be avoided, and other methods can be adopted to reduce oxygen.
Q:Is the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?
Easy to use and convenient.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:Are carbon and graphite widely used? What fields are they applied to?
High purity graphite is the main raw material for alkaline high-energy batteries widely used in the production of information and small household electrical appliances.
Q:Where is the difference between the silicon carbide crucible and the graphite crucible?
Graphite crucible special tips:1. Be careful not to let the mechanical outside hit, do not belong or strike from the top.2. Should not be exposed to water or stored in a dry place.3. Built in melt dry, without contact with water.4. In use, flames that are not directly in the crucible (jet to the bottom of the crucible) will have a marked black mark at the bottom of the crucible if it is sprayed.5. After the aluminum is stopped, the remaining copper material is tried without leaving residue in the crucible.6. Use the proper amount of oxide (slag, etc) to avoid erosion of the crucible. Excessive use may cause erosion and damage to the crucible.7. When placed in a crucible, there is no need to use mechanical power to have a significant impact.
