11. Frequently Asked Questions
Q1: Will molten metal stick to the crucible?
A: Our matching crucible is made of high-purity graphite, the optimal material to avoid metal adhesion. Minor adhesion may occur due to improper operation, different melting materials or working environments, which is a normal condition.
Q2: How many times can one graphite crucible be reused?
A: Graphite crucibles are consumable parts. Service life differs based on melting materials, operation frequency and working conditions. Inspect the crucible before every use; replace it immediately if walls thin or cracks appear.
Q3: Can I melt gold powder / silver powder for metal refining?
A: Yes, this furnace supports melting precious metal powder for refining. You need to independently adjust and control refining process parameters.
