[0001] The utility model relates to a furnace body processing device, in particular to an internal supporting device for furnace body processing. Background Art
[0002] The single crystal furnace is a device that uses a graphite heater to melt polycrystalline materials such as polysilicon in an inert gas (mainly nitrogen and helium) environment and grows single crystals without dislocation using the Czochralski method. The single crystal furnace includes the single crystal furnace cover, upper furnace cavity, furnace bottom plate, single crystal furnace auxiliary chamber, lower furnace cavity and water-cooled heat shield and other components.
[0003] At present, in the processing of single crystal furnaces, when processing components such as the single crystal furnace cover, upper furnace cavity, and lower furnace cavity, these components need to ensure the roundness of the inner wall of the furnace body. In the actual processing process, in addition to the processing of these components themselves, it is also necessary to weld some other accessories on the inner or outer wall of the components, such as fixed seats, mounting plates, etc., and these accessories are welded after the furnace body components are formed. This makes it easy for even if the roundness of the inner wall of the furnace body meets the requirements when it is rolled in the previous process, the subsequent welding of accessories may cause deformation of the inner wall of the furnace body, which in turn causes the roundness of the inner wall of the furnace body to be affected, requiring subsequent secondary repair, which is very convenient.
