用工频感应电炉来熔炼、加热铜、铝、锌等有色金属,具有热效率高,加热速度快,质量好,劳动条件好,金属烧损小,电耗少,成本低等优点,因此,它不但是国内当前铜加工企业最普遍采用的熔炼和加热设备,就是在国外,也有90％以上的铜加工厂,采用工频感应电炉来熔炼铜及其合金,因此,对工频感应电炉的供电方案,很有必要作进一步的研究。 一、对供电的要求 工频感应电炉分有铁芯、无铁芯两种。有铁芯感应电炉一般分单相、三相;而无铁芯感应电炉多为单相。
With the frequency induction furnace to smelt, heating copper, aluminum, zinc and other nonferrous metals, with high thermal efficiency, heating speed, good quality, good working conditions, small metal burning, low power consumption, low cost, etc. Therefore, it Not only is the most commonly used domestic copper processing enterprises smelting and heating equipment, is in foreign countries, there are more than 90% of copper processing plants, the use of frequency induction furnace to smelt copper and its alloys, so the power frequency induction furnace Program, it is necessary for further study. First, the requirements for power supply Frequency induction furnace sub-core, no core two. A core induction furnace generally single-phase, three-phase; and non-core induction furnace mostly single-phase.
