Treatment after rod splitting
Thread Content
When the silicon rod reached the middle stage (with a diameter of around 80–90), cracks were found at the crossbeam (there was no significant change in the current flowing through the silicon rod), yet it was intended to continue growing. Is it better to apply less current to this phase at this time? Is more current better? Is the quantity good? Is it better to reduce the volume?
It’s normal; no need to worry about it. The temperature can be lowered a bit if necessary
It doesn’t matter, but it’s easy to tip over when the furnace is shut down.
I think it’s better to reduce the current slightly; wait until the cracks have been repaired before increasing the current again
Lower the temperature; no current is applied to the cracked phase.
Current should be applied again after cracks have healed as a result of reducing the current, but attention must be paid to temperature changes both when reducing and increasing the current.
Consider maintaining and repairing it first before thinking about a normal shutdown; that should work
The amount of the air-fuel mixture can be adjusted appropriately (increased).
Keep the air intake volume unchanged; it still needs to be increased as required. However, first stabilize the current, or reduce it slightly, and then increase it after the growth period has lasted longer. Take your time – there’s no need to rush. When stopping the furnace due to rod cracking, be especially careful not to reduce the current abruptly, as this will definitely cause problems. Wish you smooth production!
