Gold Melting Graphite Crucible , Induction heating crucible for melting platinum furnace
The use of products:
1,Crucible should be placed at a dry place or placed in a wooden frame
2,The crucible tongs should be matched to the shape of crucible to avoid damage crucible
3,The quantity of the feeding should be based on the capacity of the crucible, do not feed too much or too tight, otherwise the crucible may be bursted
4,We should tap the crucible when clean the slag, in order to avoid damage the crucible body
5,The pedestal of crucible placed should put some kelp, carbon powder or asbestos powder,pedestal should be matched to the bottom of the crucible, the crucible placed in the center of furnace.
6,There should be maintained distance between crucible and furnace and the crucible should be fixed firmly by wedge
7,Using an excess oxidizer will reduce the life of the crucible.
