Product details
Graphite heater is a heat source in the polycrystalline ingot process. Its size and position directly affect the temperature distribution and solid-state interface during the growth of polycrystalline silicon crystal. The top-side heaters currently used can be obtained during polysilicon melting and crystal growth. Better efficiency and solid-liquid interface.
As a heat source for directional solidification technology, graphite heater mainly provides energy for melting and crystal growth process through radiation heat transfer, which is directly related to whether the temperature field of molten ingot melting and crystal growth is reasonable and stable. Therefore, it is necessary to study different heater sizes and The effect of the location on the thermal field distribution in the ingot furnace. Numerical simulation of the temperature field during the solidification of polysilicon is an efficient and important technical means to determine and optimize process conditions more economically and quickly.
