一、前言刚玉电弧炉是磨料行业耗能极大的设备。电弧炉电极耗能占电炉总功率的比例甚大。据测算,如果全面地考虑了电阻热及导热、蓄热损失之后,刚玉电弧炉电极耗能一般高达全炉总能量的12～16%,因此,电极设计成为电炉设计的重要内容之一。电极设计的任务是根据电极所处之环境,电极的物理化学性质,电极规格等条件,估计在通过工艺要求的电流时,
First, the foreword Corundum electric arc furnace is a great energy consumption abrasive equipment industry. Electric arc furnace electrode energy consumption accounted for a large proportion of the total power furnace. It is estimated that if the heat resistance and thermal conductivity and heat storage loss are considered comprehensively, the energy consumption of the corundum arc furnace electrode is generally 12-16% of the total energy of the furnace. Therefore, the electrode design becomes one of the important contents of the electric furnace design. Electrode design task is based on the electrode in which the environment, the electrode of the physical and chemical properties, electrode specifications and other conditions, estimated through the process of the current requirements,
