在伟大领袖毛主席关于工业“以钢为纲”的方针指引下,我国钢铁工业正在突飞猛进地向前发展。采用中频感应电炉熔炼有许多独特的优点:对于熔炼贵重合金和稀有元素有着十分理想的工艺过程;能快速加热,热效率很高;设备周围温度低,环境污染小,因而作业环境良好;可以用电控制加热,质量管理容易,适于自动控制,操作简单、节省人力。鉴于上述优点,国内铸造行业采用感应电炉熔化金属的正在增多,锻造行业采用感应加热的也迅速增多。用于感应熔炼及感应加热的中频电源,过去大都采用电动发电机组。随着可控硅技术的发展,为试制静止中频电源创
Under the guideline of Chairman Mao, the great leader, on industrial “taking steel as the key link,” China’s steel industry is advancing by leaps and bounds. The use of IF induction furnace smelting has many unique advantages: for the melting of precious alloys and rare elements has a very good process; can be quickly heated, thermal efficiency is high; equipment around the low temperature, environmental pollution is small, so the working environment is good; you can use electricity Control of heating, quality management is easy, suitable for automatic control, simple operation, save manpower. In view of the above advantages, the domestic foundry industry using induction furnace melting metal is increasing, the forging industry also increased rapidly with induction heating. For induction melting and induction heating IF power supply, the past mostly used motor generator. With the development of thyristor technology, for the trial of static IF power supply record
