Product Description

Product Description

 
 GRAPHITE CRUCIBLE
 
The graphite crucible is a kind of graphite mold, used as a carrier, which can put the raw materials and parts that we need to position or shape together in the graphite mold for high-temperature sintering, melting, or casting. 
 
The graphite crucible is made of artificial graphite blocks by mechanical processing.

THE ADVANTAGES OF A GRAPHITE CRUCIBLE ARE AS FOLLOWS:
 
High-purity graphite crucible has excellent thermal stability, corrosion resistance, impact resistance, acid corrosion resistance, high thermal conductivity and quality stability; it has a certain resistance to rapid heat and cold. 
 
It is a kind of very excellent performance in molten gold crucibles, and is currently widely used in alloy tools the smelting of steel, and the smelting of non-ferrous metals and their alloys. 

However, improper use of high-purity graphite crucibles will greatly affect their performance and service life.

ATTENTION TO THE GRAPHITE CRUCIBLE WHEN USING: 

1. The high-purity graphite crucible must be slowly baked to 500 degrees Celsius before use. After use, it must be placed in a dry place to avoid water intrusion.

2. When using it, it must be added according to the capacity of the high-purity graphite crucible, and the metals placed should not be squeezed too tightly to prevent the metal from thermally expanding and cracking the crucible.

3. When taking out the molten metal after melting, it is best to scoop it out with a spoon, use calipers as little as possible, and pay attention to the action to be light, to avoid impacting the crucible with excessive force and damage.

4.  When using a high-purity graphite crucible, avoid a strong oxidizing flame directly spraying on the crucible wall, which will damage the crucible and shorten the service life.
 
The high-purity graphite crucible has excellent performance, but in order to better use and prolong the service life of the high-purity graphite crucible, we must know the above instructions to avoid damaging it.
