Description

technical field

[0001] The invention relates to the technical field of single crystal furnaces, in particular to a hoisting device for a single crystal furnace guide tube. Background technique

[0002] At present, single crystal silicon is usually produced by using a single crystal furnace. The main components of the single crystal furnace from bottom to top include furnace floor, furnace body, furnace cover, flap box, auxiliary furnace, etc., and jackets are installed inside each part. layer, cooling water circulates in the jacket. Monocrystalline silicon is generally produced by the following method: put polycrystalline silicon into a quartz crucible in the furnace body, polycrystalline silicon is heated and melted in the quartz crucible, and then the molten silicon is cooled slightly to give a certain degree of supercooling, and the seed crystal is placed in the furnace. In the silicon seed crystal holder, the upper end of the seed crystal holder is connected to the seed...
