The flame should be sprayed on the base of cruciblewhen in use, and the crucible body should be avoided7. from direct flame spraying.6.Charging must be slow, anddo not chargetoo much, too tight, so as not to crack the crucible.7.The crucible tongs used for loading and discharging should match the shape of the crucible so as not to damage the crucible.8.The crucible is best to be used continuously, so as to better play its high performance.9.It is necessary to control the dosage of additives in the melting process,overuse willreducethe life of the crucible.10.The crucible should be knocked gently when removing slag and coking on the inner and outer walls to avoid damaging the crucible.
