Every graphite crucible is manufactured through the spirit of human soul. It should be used correctly with love. Because of the different use methods, there are long life and short life. It can also be said that graphite crucible has life.
1) Positive positioning method of crucible
2) Input Method of Melting Materials
Material shall be loaded longitudinally in the crucible as shown in the figure. The aluminium ingot obliquely contacts the side wall of the crucible, and the crucible may be squeezed and cracked due to thermal expansion.
After the fused soup is scooped out, please be careful not to leave any residual soup. The crucible rupture is caused by the rapid thermal expansion of the solidified residue soup during the next melting.
For the combustion in the crucible, attention must be paid to the design and adjustment of the burner in the furnace to make it burn completely under the crucible and the crucible. As shown in the figure, it is desirable to turn red in the order of When heating, care should be taken not to carry out in the state of peroxide, as far as possible in a short period of time for rapid heating.
In addition, the slag remover has a negative impact on graphite crucible, and it is necessary to pay attention to the use of not too much.
