Electrical issues during polysilicon production
Thread Content
Recently, we have been facing frequent issues with the rods falling over during production, and these rods end up against the furnace walls. Yet the control system shows that everything is normal, with no changes in current or voltage. If this hadn’t been detected on site in a timely manner, the consequences would have been severe. What could be the cause of this?
Electrical system issue – which polysilicon plant are you at? The situation you described with the furnace is very dangerous; if the problem isn’t resolved, it’s best for you to bring a stool and stay by the furnace 24 hours a day, otherwise… . . . . The consequences will be severe, and the losses will be huge!
You are very lucky. In Henan, there was an incident where the furnace wall was damaged due to a furnace failure, resulting in an explosion that killed two people; it was extremely dangerous
Don’t you have any electrical protection device for the furnace body either? The silicon rods should automatically trigger a power cut when they come into contact with the furnace wall; an emergency shutdown should be initiated in such cases
