The graphite disc is composed of a graphite cap, a graphite card holder and a graphite chuck. Graphite discs are indispensable tools for the stretching of monocrystalline/polycrystalline silicon and polycrystalline silicon.
In the solar photovoltaic thermal field, the graphite disc is one of the important parts in the polycrystalline furnace, and the graphite disc has a slight difference in the shape of the manufacture under different uses. The quality of the graphite disc directly determines the quality of the crystalline silicon. In the manufacture of graphite discs, strict selection and fine processing are required.
Hongsheng Graphite specializes in manufacturing graphite bells for graphite reduction furnaces, graphite shaped parts; fixed carbon: 99.9; product name: graphite disc/graphite base; specification: 325 (mesh) model: various types of grade: joint strong moisture: 0.01 (%) Ash: 0.01% compression ≥ 80Mpa resistance ≤ 10uΩm flex ≥ 45Mpa.
Graphite calipers for graphite reduction furnaces, graphite pedestals, can be processed according to customer drawings, quality assurance. At the same time, the unit will also use high purity graphite and carbon-carbon composites. Such as graphite disc, graphite crucible, graphite electrode, three trays, three disc brackets, brackets, upper and lower insulation cover, inner and outer guide tubes, upper and lower insulation tubes, furnace bottom insulation tube, bottom plate, exhaust jacket, lower shaft protection Graphite products such as sleeves, electrode sheaths, thermostats, heat shields, and heat shield holders.
