Description
まず、図1を参照して、本発明により誘導加熱する被加熱物26、および誘導加熱装置10について説明する。本実施形態で誘導加熱する被加熱物26は、筒状態の外周部に、ほぼ等間隔に複数の凸部を有する部材である。このため、当該被加熱物は、凸部を有する部分が厚肉部24、凸部を有さない部分が薄肉部22となる。被加熱物26の構成部材としては、導電性部材であれば良いが、カーボン、スチール、タングステン等の、比較的電気抵抗の高い金属部材であれば、高い加熱効率を得ることができる。
なお本実施形態では、凸部を有さない部分、すなわち薄肉部22の厚みをta、凸部を有する部分、すなわち厚肉部24の厚みをtbと表すこととする。
なお、被加熱物に対する誘導加熱コイルの距離は、絶縁もしくは耐熱と加熱効率から決定される。
一般的には、厚肉部24に比べて薄肉部22の加熱割合が大きくなってしまうといった現象が生じるからである。
Claims (2)
- 厚肉部と薄肉部とを有する被加熱物を誘導加熱する方法であって、
前記被加熱物の内側と外側、又は前記被加熱物の表側と裏側にそれぞれ誘導加熱コイルを配置し、
前記2つの誘導加熱コイルに投入する電流の周波数を一致させ、
前記2つの誘導加熱コイルに投入する電流波形の位相角をずらすことで、前記被加熱物内部に生ずる渦電流の重畳と打ち消しの割合を変化させ、
前記被加熱物における前記薄肉部の発熱密度と前記厚肉部の発熱密度とを調整することを特徴とする加熱部位選択的誘導加熱方法。
