The invention relates to a silicon core structure for polycrystalline silicon production. The structure includes a first silicon core, a second silicon core and a cross beam for overlapping of the first silicon core and the second silicon core, and also includes graphite connecting pieces. Each graphite connecting piece includes a silicon core overlapping part for fixing the first silicon core anda cross beam overlapping part for fixing the cross beam. The silicon core structure for polycrystalline silicon production provided by the invention adopts the graphite connecting pieces to connect the first silicon core and the cross beam, and each graphite connecting piece includes the silicon core overlapping part for fixing the first silicon core and the cross beam overlapping part for fixingthe cross beam, the graphite connecting pieces can fix the first silicon core and the cross beam together stably, and the graphite connecting pieces are conductive, thus ensuring current conveyance during use of the silicon core structure for polycrystalline silicon production, and reducing the turning-down rate.
Description
technical field [0001] The invention relates to a silicon core structure, in particular to a silicon core structure for polysilicon production. Background technique [0002] The silicon core structure used in the production of polysilicon by the reduction furnace is generally a frame structure, including the first silicon core, the second silicon core and the beam. On top of the core and the second silicon core, the beam is bound to the first silicon core and the second silicon core by molybdenum wire. [0003] However, this silicon core structure is fixed by molybdenum wire, which has limited structural strength, and often falls during the growth process, resulting in production accidents. Contents of the invention [0004] In order to solve the above technical problems, the present invention aims to provide a safer silicon core structure of a polysilicon reduction furnace. [0005] The present invention includes the following content: a silicon core structure for polys...
