Numerical Simulation Analysis on Lengthwise Graphitization Furnace Co-Production Silicon Carbide

The effective thermal conductivity coefficient of silicon carbide (SiC) synthesis materials and graphitization furnace insulation material were obtained by applying heat percolation theory and thermal coefficient equation of various layer-compositors. This paper proposed a further numerical analysis on the temperature distribution of SiC furnace, lengthwise graphitization (LWG) furnace and Co-production furnace by open source finite element software FEPG. The results show that the Co-production furnace can produce SiC after finishing graphitization production and Co-production furnace’s energy consumption subtract energy consumption of LWG furnace, SiC production energy consumption of Co-production furnace is half and SiC yield of Co-production furnace is 57-73 percent of same type of SiC furnace. Besides, applying Co-production process could reduce the exhaust of whole LWG furnace.
