Based on the analysis of production process in three phases and finite element analysis of silicon carbide (SiC) furnace temperature field, 2D thermal-seepage coupled finite element model was built to know production practical situation by temperature distribution and pressure distribution. The relation of SiC furnace inside pressure and power was obtained by pressure distribution as well. Then this paper built power curve optimization model that minimizing product energy consumption is objective function with extreme pressure of spouting as one constraint condition, and simplified optimal algorithm plan was proposed based on three production phases. To verify the optimization results, the powers of before optimization and after optimization were employed on the basis of actual industrial furnace data. Results show that energy consumption decreases about 5% and the SiC output increases about 10%. Besides, production period is nearly unchanged after optimization. All stated illustrate the effectiveness of the proposed method.
