一前言目前,由于世界上石油资源的不稳定,节约石油不仅是涉及企业部门而且也波及到了每一个家庭,所以节省能源已在世界范围内引起了重视。特别是热处理部门,为了防备燃料费涨价,都在实施炉壁纤维化,更换能源以及提高效率等热处理炉节能措施。处在这样的时期,高频感应加热法作为节能措施而得到了重新的评价。 I. INTRODUCTION At present, due to the instability of oil resources in the world, saving oil not only involves the enterprise sector but also every family, so saving energy has drawn great attention in the world. In particular, heat treatment departments are implementing energy-saving measures for heat treatment furnaces such as furnace wall fiberization, energy replacement, and efficiency improvement in order to prevent fuel price increases. In such a period, the high-frequency induction heating method has been reevaluated as an energy-saving measure.
