本発明の一態様によれば、駆動源が停止し冷却システムによる被処理物に対する冷却が停止すると、第2冷却システムが作動して被処理物に対する冷却が続行される。
この場合には、電力の供給が停止し冷却システムによる被処理物に対する冷却が停止すると、非常用電源によってポンプが駆動されて被処理物に対する冷却が続行される。
この場合には、電力の供給が停止すると上記バルブは開状態となる。そのため、被処理物の上側に位置するノズルから冷却用液体が冷却炉内に供給される。
この場合には、電力の供給が停止し冷却システムによる被処理物に対する冷却が停止すると、非常用電源によって特定のポンプが駆動されて被処理物に対する冷却が続行される。そのため、非常用電源の容量を特定のポンプを駆動させるに十分な容量に限定することが可能となる。
この場合には、駆動源が停止し冷却システムによる被処理物に対する冷却が停止すると、第2バルブが開状態となる。そのため、冷却炉より上側に設けられる貯留槽からノズルを介して冷却用液体が冷却炉内に供給される。
この場合には、駆動源が停止すると第2バルブは開状態となる。そのため、被処理物の上側に位置するノズルから冷却用液体が冷却炉内に供給される。

本実施形態における冷却室3Aを、図4を参照して説明する。
図4は、本実施形態における冷却室3Aの概略図である。なお、図4における冷却室3Aは、図1のA-A線から見た断面図である。また、図4において、図2に示す第1の実施形態の構成要素と同一の要素については同一の符号を付し、その説明を省略する。
本実施形態によれば、電力Eの供給が停止し冷却システム30による被処理物Mに対する冷却が停止しても、第2冷却システム40Aが作動して被処理物Mに対する冷却を続行することができる。そのため、電力Eの供給停止という非常時において、被処理物Mの熱によって冷却室3Aが破損することを防止できる。
