1. 感应熔炼炉的节能措施(1)感应熔炼炉的种类感应熔炼炉从构造方面可分为无芯式(坩埚型)和铁芯式(沟型)两类。由于使用的电源不同,坩埚型又可分为低频炉和高频炉。沟型炉只有低频炉。本文所指的低频就是工业用的50或60赫芝的电源,所谓高频就是采用电动发电机组、可控硅变换器或真空管振荡器等变频装置产生500、1000、3000、10000赫芝及20、50千赫芝的电源。
1. Induction smelting furnace energy-saving measures (1) Induction smelting furnace induction Smelting furnace from the structure can be divided into coreless (crucible type) and core type (groove type) two categories. Due to the different power sources, crucible type can be divided into low frequency furnace and high frequency furnace. Groove type furnace only low-frequency furnace. This article refers to the low-frequency industrial 50 or 60 Hertz power supply, the so-called high frequency is the use of motor-generator sets, SCR converters or vacuum tube oscillator and other frequency devices produce 500,1000,3000,10000 Hertz and 20 , 50 kHz power supply.
