PRE HEAT PROCEDURE
For new crucibles and/or after long cool off phase crucible - Heat empty crucible slowly to 390F to eliminate any moisture, then heat on low power to 600C OR up to bright red hot condition.
However the slow heating phase to 390F should be adopted whenever the crucible has been allowed to cool off for extended periods.
In the case of large capacity crucibles and furnaces with high output burners the rate of temperature rise should be controlled in the initial stages to avoid thermal stress.
SAFTY
Proper safety clothing and equipment must be worn at the time of pouring.
Any residual moisture must be removed slowly from the crucible and/or furnace refractories before use.
Ensure that no moisture or volatile materials are introduced into the melt.
It is used as transfer vessels must be sufficiently pre-heated before being filled with molten metal.
Hot crucibles should not be placed down on a cold surface and should only be used for the purpose for which it is designed.
