在毛主席革命路线指引下,近几年来我国可控硅变频装置的研制和使用均发展得很快,特别是利用可控硅变频的中频电源在我国铸造生产中用于熔炼黑色金属和有色金属,因其与中频机组相比较具有熔炼时间短,效率高,省电,安装简单,噪音小等优点而已逐步被广泛应用。就在这样的大好形势鼓舞下,在广大使用单位迫切需要的情况下,我厂于1973年年底接受了试制150公斤中频感应炼钢炉的任务。我们遵照毛主席关于“自力更生,艰苦奋斗,破除迷信,解放思想”的伟大教导,在上级领导的关怀下,在许多兄弟单位的帮助和指
Under the guidance of Chairman Mao’s revolutionary line, in recent years, the development and application of thyristor frequency conversion devices in our country have been developing rapidly. In particular, the mid-frequency power supply using thyristor frequency conversion is used to smelt ferrous and non-ferrous metals , Because of its intermediate frequency unit has a melting time is short, high efficiency, power saving, simple installation, noise and other advantages have gradually been widely used. Encouraged by such a favorable situation, under the urgent need of the vast majority of units, our factory at the end of 1973 accepted the task of trial production of 150 kg medium frequency induction steelmaking furnace. In accordance with Chairman Mao’s great teaching on self-reliance, hard work, dispelling superstitions and emancipating the mind, we have the help and guidance of many fraternal units under the care of the higher authorities
