摘要
采用数值模拟的方法对艾奇逊碳化硅合成炉中的石墨电极进行热场分析,同时研究了杂质颗粒对于电极的影响。研究表明电极上温度分布基本均匀,除与炉芯直接相连部分外,大部分温度维持在90~150℃。同时可以看出电极中杂质粒子的存在会造成明显的温度梯度,随着杂质粒子粒径的增加温度梯度也在增加,生产中可在电极表面进行抗氧化喷涂处理,提高电极的纯净度从而延长电极使用寿命。
Through numerical simulation of thermal field on graphite electrodes in Acheson Si C synthesis furnace was analyzed. The results show that the temperature distribution is basically uniform on the electrode surface,and the most of the temperature is maintained at 90~150℃except for the part directly connected with the furnace core. At the same time the impurity particles in the electrodes caused obvious temperature gradient,with the impurity particle size increase the temperature gradient is increased. Anti-oxidation coating can be applied on the electrode surface during production to improve the purity of the electrode so as to prolong the service life of the electrode.
