摘要
分析了中频电炉内的负载特性、各种状态的负载参数，以及对启动特性产生的影响。找到了铁坩埚模为负载时，逆变电路启动困难或不能启动的原因，找出了解决的措施。
his paper has analysed the load characteristic of middlc frcqueney electric ovcn,theload paramctere of various stalus and their influence on start charaetristies.If has foundout the reason of difficult starting or even starting failure of reverse convertion circuitwhen the iron crucible mode is to be the load.The methods to solve if have been provid-ed.
