Embodiment approach 1
[0017] Implementation mode 1: if figure 1 , 2 As shown, the polysilicon reduction furnace body includes: 1-furnace body insulation cylinder, 2-stainless steel bolts, 3-furnace body wall, 4-furnace body wall, 5-new inner wall, 6-insulation layer, 7-bolts hole. Wherein, newly-increased inner wall 5 selects the stainless steel sheet that thickness is 0.2mm for use, and its overall shape is identical with furnace body, can be divided into rectangle ( image 3 ), the area of each rectangular stainless steel sheet is 0.1 square meters (2m high, 0.05m wide), and 8 bolt holes are opened on the sheet, and the hole size is 10mm, which is mainly used for fixing needs and heat transfer control Need, the stainless steel sheet is polished by the machine tool, the polishing process is convenient and the polishing effect is good, and the polished mirror surface roughness can achieve Ra0.008μm. The stainless steel bolt 2 used is M8 in type and has a length of 60mm. By adjusting the positi...
