摘　　要：多热源合成SiC冶炼炉炉体尺寸大,一次性生产原材料消耗大,用实验手段难以预测给定条件下的热源数目等参数。通过对冶炼炉温度场的数学分析及数值模拟,以合成SiC温区断面面积比率最大为原则,提出了多热源合成SiC热源数目的判定模型,给出了实例,并通过工业实例对模型进行了验证。热源数目的预测,可以为SiC工业生产提供理论指导。It is difficult to forecast the number of heat-source and distance of the multi-heat-source synthesis silicon carbide furnace by experiment before silicon carbide industrial synthesis, because the furnace volume is huge and the consumption of raw material is enormous. Through the mathematical analysis and numerical simulation of the furnace temperature field, the model for determining heat-source number in multi-heat-source synthesis silicon carbide furnace is put forward. The computational example is given under the industrial parameter condition. With the engineering example, the decision model of heat-source number is testified.
