电极盐浴炉是应用极广的热处理设备。这类设备的一个主要缺点是启动困难,必须使用辅助电极启动,操作麻烦,也不安全,而且由于电极材料和结构上的限制,一般只能小功率启动,启动时间长,耗电量大,很不经济。为此,人们一直在探求简便易行、不需另加电极、直接快速启动的新方法,并且取得了许多有益的进展。其中利用特殊结构电极,进行大功率直接启动是一个行之有效的新途径。我单位热处理车间,经过反复试验和不断改进,试制成功一台单相45千瓦电极全浸式直接启动盐浴炉。这种盐浴炉不需启动电极,可直接启 Electrode salt bath furnace is a very wide range of heat treatment equipment. A major disadvantage of this type of device is that it is difficult to start up and must be started with an auxiliary electrode which is troublesome and unsafe to operate and which, due to electrode material and structural limitations, generally has low power start-up, long start-up time, Very uneconomical. To this end, people are always looking for a new method that is simple and easy to operate, requires no additional electrodes, and is directly activated quickly, and many beneficial developments have been made. One of the special structure of the electrode, high-power direct start is an effective new way. My unit heat treatment workshop, after repeated testing and continuous improvement, trial success of a single-phase 45 kilowatts electrode immersion direct start salt bath furnace. This salt bath furnace without starting the electrode, can be directly Kai
