Three-phase power failure during the startup process of the reduction furnace
Thread Content
Dear experts: I need help. The company currently has a reduction furnace; in the previous batch, the silicon core had a height of 2500, and it operated for about 100 hours without any issues. Later, the height of the silicon core was adjusted to 2600 mm; after operating for about 55 hours, a triphase power failure occurred, forcing an emergency shutdown of the furnace. What is the reason for this issue? Is it because the silicon core is too tall? Please ask an expert to help, thank you
It’s probably an individual case; it seems to have little to do with the height of the silicon core. See what fault caused the restoration of the telegraph signal; if the rod did not fall, the furnace could have been restarted at that time.
Is there any issue with the quality of the furnace assembly, especially whether the grooves in the insulation sleeves have been cleaned properly?
