| NAME：Quartz feeder | NAME：Quartz cone | NAME：Quartz sheath | NAME：Quartz seam detector | NAME：Quartz guiding tube |
| PURPOSE：Used for refeeding when pulling monocrystalline silicon. |
PURPOSE：Used with quartz feeder when refeeding for monocrystalline silicon pulling. |
PURPOSE：Used to protect graphite electrode of single crystal furnace. |
PURPOSE：Used to measure the distance between the liquid surface and the guiding tube |
PURPOSE：Instead of graphite internal guiding in CZ method, quartz guiding tube has the advantage of high purity and low cost. |
