Maximize Your Crucible’s Service Life
Crucibles with a long service life allow managers to plan longer production campaigns, schedule crucible replacement with minimal downtime and reduce replacement frequency. Further, mindful crucible care avoids dangerous incidents of failure occurring during use. While service life depends on the manufacturer and product quality, metalcasters also can extend service life though proper crucible care. For the best results, your
crucible should be the right one for your application. Crucible choice depends on:
• Specifi c alloy or range of alloys. • Type of furnace.

CLEANING/ FINISHING
• Melting and holding temperatures.
• Rate of temperature change. • How the crucible is charged. • Fluxes. • How slag or dross is removed. • How the crucible is poured.
Once the crucible is purchased
and delivered, it’s up to you to properly care for and use it to optimize service life. When your crucible arrives on
your receiving dock, perform an inspection to verify it did not suffer shipping damage.
If the new crucible passes your inspection, move it carefully to storage or the furnace. Ideally, crucibles should be moved on the pallet or in the shipping carton. Read more about crucible care from this article by Morgan Molten Metal Systems, Wallingford, Conn., at
