Usage Instructions

1. Preheat the crucible before melting or casting metals to avoid sudden temperature changes. During heating, support the crucible with a mud triangle bracket at the bottom. Avoid rapid cooling after use as the crucible's resistance to strain is limited, and excessive temperature followed by a sudden drop can pose potential hazards.

2. When adding heating materials to the crucible, pour slowly and leave sufficient space for air circulation to enhance melting efficiency. Overfilling may cause metal to spill out during the smelting process, posing a risk to operators.

3. Given the high efficiency of the silicon carbide crucible, when nearing evaporation, it is crucial to maintain concentration and use residual heat for evaporation instead of allowing the crucible to dry completely. The evaporation process should be slowly cooled down and handled appropriately. It is essential to carefully read and follow the relevant operating instructions to avoid improper handling.
