摘　　要：玻璃电熔化作为20世纪50年代发展起来的新熔化工艺技术一直被玻璃窑炉普遍应用,而作为给各类玻璃熔液传输电能的电极,又因为各种熔化机理等原因在生产运行过程中会出现侵蚀,使在玻璃熔窑的电极表面积逐渐变小,电极电流密度逐渐变大,影响窑炉与电极的寿命。主要结合玻璃电熔普遍采用钼电极在多个全电熔窑、电助熔窑生产运行与改造的电极数据,浅谈电极电流密度的推算与修正,指导玻璃窑电熔(电助熔)中后期的电极运行与维护。As a new melting technique developed in 1950 s, electric melting has been widely used in glass furnaces. The electrodes for transmitting electric energy to various types of glass melts may be eroded in the operation due to various melting mechanisms and other reasons, which causes the surface area of the electrodes in the glass furnace to gradually decrease, and the electrode current density to gradually increase, thus affecting the service life of the furnace and the electrodes. Mainly based on the data of molybdenum electrodes commonly used in the operation and transformation of multiple all-electric melting furnaces and electric boosting furnaces, this article discusses the calculation and correction of electrode current density, and guides the operation and maintenance of electrodes in the middle and later phases of electric melting(electric boosting) furnaces.
