简要说明了中频感应电炉漏炉报警系统的作用和分类.重点介绍了几种不同形式的报警系统的原理、使用特点,以供尚未配置报警系统的电炉设备制造厂家和已经使用中频感应电炉但尚未安装电炉报警系统的厂家参考.特别强调,操作者在任何情况下都不要误以为安装了有预报警性质的漏炉检测报警装置就可以完全放心,因为在正常生产过程中,漏炉检测报警装置一旦报警,就表示炉体漏炉事故已经发生了.%The working principle and usage situation of the metal leakage alarm system used for the medium frequency induction furnace was briefly explained. At the same time, different types of alarm systems were introduced as the reference for those furnace manufacturing enterprises which producing furnace still without alarm system and the foundries which has been using induction furnace but without alarm system. It is the writer's hope and suggestion that the relevant equipment manufacturers develop some simple and applied separated alarm system for usage of induction furnace-using foundries.
