盐浴炉是金属热处理中一种重要加热设备。近年来国内普遍将插入式电极改为埋入式盐浴炉。由于电极布置在盐浴内下面的炉壁中,所以具有如下特点:1.由于电极不占用炉膛面积,炉膛利用率高。在提高装炉量的情况下,热损失一样,相对而言,则减少了电力消耗。2.电极对置安装在接近盐浴的底部处,电流流经大部熔盐对流循环较好,因此盐浴温度比较均匀。3.由于电极埋在炉内,与空气隔断,所以电极寿命增长,相应也减少了盐渣。4.操作方便,便于机械化,自动化。
Salt bath furnace metal heat treatment is an important heating equipment. In recent years, the general insert electrode into a buried salt bath furnace. Since the electrode is arranged in the furnace wall below the salt bath, it has the following characteristics: 1. Since the electrode does not occupy the hearth area, the furnace efficiency is high. In the case of increasing the loading capacity, the heat loss is the same, while the power consumption is reduced. 2. Electrode installed opposite the bottom of the salt bath, the current flow through the majority of molten salt convection cycle is better, so salt bath temperature is more uniform. 3. As the electrode buried in the furnace, cut off from the air, so the electrode life expectancy, the corresponding reduction of salt residue. 4. Easy to operate, easy mechanization, automation.
