Precautions for the use of graphite crucible for buffer modulation wave melting aluminum furnace:

1 Handle with care when feeding, and don’t put it in the crucible vigorously, so as not to break the crucible. The liquid level of the molten aluminum in the pot should not exceed the lower edge of the iron ring of the panel. Do not increase the amount at will, causing the molten aluminum to overflow and damage the furnace body. The company will not be responsible for the loss and it is not included in the scope of repair. The cost of repairs will be calculated separately.

2 During normal use, it is recommended to replace a new crucible within 6-8 months. If the crucible is not replaced within 6-8 months, the company will not be responsible for the equipment and other losses, and repairs will not be guaranteed.

3 The crucible has a longer service life than 24 hours non-stop. The dissolved soup in the crucible must be removed when the furnace is shut down to avoid expansion when the molten soup is solidified and reheated, which will affect the life of the crucible or even burst the crucible.

4 Dissolving aids: the dissolving aids for aluminum alloy (FLLUX) and copper alloy borax, please use a small amount because a large amount will corrode the crucible wall, and the additive needs to be placed in the crucible when the aluminum metal is dissolved into the soup for a minimum of 8 minutes Stir quickly to avoid adhering to the inner wall of the crucible and eroding the crucible. For aluminum alloy additives such as sodium (NA) content exceeding 10%, special crucibles are required.

5 After the daily work is completed, when the crucible is still red, please quickly cut and clean the metal material attached to the crucible wall, so as to avoid excessive residues that affect heat transfer and increase the dissolution time, causing thermal expansion and bursting of the crucible.
