carbon/carbon hardened felt insulation
Carbon/carbon hardening insulation felt (also known as curing insulation felt) in the ingot furnace, set heat insulation and protection functions in one, low thermal conductivity can ensure better energy saving effect. At present, the overall product specifications of large size that can be prepared are as follows. The thickness can be designed according to the furnace type and customer requirements:
Carbon/carbon Insulation cylinder for polysilicon reduction furnace
Super size using 2 invention patent technology development (2340 x 3100 Φ) mm insulation plate, is currently the largest C/C composite material products. According to the ability of technical equipment of precast body and dense super size can be prepared Φ 2650 mm cover of carbon/carbon heat insulation products. The energy consumption of reducing furnace can be reduced by 20%-40% after using heat shield.
Compared with graphite crucible, carbon/carbon crucible has the outstanding characteristics of light weight, strong erosion resistance, long service life and high cost performance. It can be widely used in monocrystalline silicon furnaces of various types and specifications, and can be customized and designed according to the furnace type and transformation requirements of customers.
