The invention discloses a polysilicon reduction furnace silicon core mounting device and method, and relates to the technical field of polysilicon production. The device comprises a silicon core mounting disc used for fixing a silicon core assembly according to a distribution structure of a preset reduction furnace chassis electrode; a silicon core lifting mechanism corresponding to the silicon core mounting disc and used for lifting the silicon core assembly to the silicon core mounting disc for fixing. In the above technical scheme, the silicon core assembly can be pre-distributed and fixedaccording to the distribution structure of the preset reduction furnace chassis electrode through the silicon core mounting disc. When a reduction furnace chassis is cleaned, the silicon core mountingdisc can be directly utilized to install the pre-distributed and fixed silicone core assembly on the preset reduction furnace chassis. The operation is very fast, the auxiliary time without output can be saved, and the overall production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of polysilicon production, in particular to a silicon core installation device and installation method for a polysilicon reduction furnace. Background technique [0002] At present, from the development process of international solar cells, it can be seen that its development trend is monocrystalline silicon, polycrystalline silicon, ribbon silicon and thin film materials (including microcrystalline silicon-based thin films, compound-based thin films and dye thin films). [0003] Among them, polycrystalline silicon is a form of elemental silicon. When molten elemental silicon is solidified under supercooled conditions, silicon atoms are arranged in the form of diamond lattices to form many crystal nuclei. If these crystal nuclei grow into crystal grains with different crystal plane orientations, these crystal grains combine to crystallize into polycrystalline silicon. . [0004] The production of polysilic...
