Discussion on the methods for harvesting silicon rods from polycrystalline silicon furnaces
Thread Content
Hello everyone. The company uses 18-bar reduction furnaces to produce polysilicon. Once the silicon bars reach a length of over 120 mm, the polysilicon bars are harvested; each bar is approximately 2000 mm in length. The furnaces have to be disassembled manually every time, which is dangerous – although safety measures are in place, employees can still easily get injured； Second, it wastes time and reduces the equipment’s operational efficiency. I would like to ask if anyone has any good methods or equipment that can be used during the process of dismantling furnaces to extract silicon rods, in order to ensure the safety of employees and improve the operational efficiency of the equipment? Thank you all for the discussion.
Use a robotic arm; manual handling is indeed very dangerous. We’ve had incidents in the past, but robotic arms are a bit expensive
There is a solution; our factory has recently designed a device of this kind that performs well in terms of worker safety. However, it still doesn’t significantly reduce the time required for tasks

It’s just a stick that’s two meters long. A pair of them weighs around 300 pounds. You can just pick them down directly. Here, a pair of such sticks weighs 450 pounds. Should we use an aerial vehicle to handle them? If it’s slow, then just do it slowly – safety first`````
Currently, manual labor is used to break the rods; in the future, each pair of rods will weigh around 600 jin, and manual labor will no longer be sufficient. May I ask how those of you upstairs use the specialized tools for removing rods with a crane? ?
Let’s carry it by hand; we use manual lifting as well. Although there are robotic arms available, they aren’t very useful. The silicon rods are too fragile, and there’s a risk that they might break during transportation. If anyone has good methods, please share them right away. Those who use cranes for lifting should also explain the specific methods involved.
It is indeed an issue worth discussing, but using a robotic arm seems a bit slow and not very efficient!
After dismantling the furnace, wrap each silicon rod individually and then remove them~~~~~~~~~
Haven’t any of you designed a device to remove the rods? Our technical staff designed one; although its quality is very poor, its safety level is quite high. I kind of miss river mussel shells.
