Title (EN) HEAT TREATMENT APPARATUS
(FR) APPAREIL DE TRAITEMENT THERMIQUE
(JA) 熱処理装置
Abstract:
(EN) In the heat treatment apparatus (1) according to the present disclosure, workpiece (W), which has been heated in a heating chamber (2), is immersed in a cooling oil (Y) retained in an oil tank (30a) so as to be cooled, the apparatus comprising a gas ejection unit (30b) for ejecting gas into the cooling oil (Y) and an oil circulating unit (30d) to recover the cooling oil (Y) from the oil tank (30a) and return the cooling oil (Y) to the oil tank (30a), and the oil circulating unit (30d) being provided with a cooling unit (30j) for cooling the cooling oil (Y).
(FR) Dans l'appareil de traitement thermique (1) selon la présente divulgation, une pièce (W), qui a été chauffée dans une chambre chauffante (2), est immergée dans une huile de refroidissement (Y) confinée dans un réservoir d'huile (30a) de façon à être refroidie, l'appareil comprenant une unité d'éjection de gaz (30b) qui éjecte un gaz dans l'huile de refroidissement (Y) et une unité de circulation d'huile (30d) qui récupère l'huile de refroidissement (Y) confinée dans le réservoir d'huile (30a) et recycle ladite huile de refroidissement (Y) vers le réservoir d'huile (30a), l'unité de circulation d'huile (30d) étant pourvue d'une unité de refroidissement (30j) qui refroidit l'huile de refroidissement (Y).
(JA) 本開示の熱処理装置(1)は、加熱室(2)で加熱した被処理物(W)を油槽(30a)に貯留された冷却油(Y)に浸漬させて冷却する熱処理装置であって、冷却油(Y)に気体を噴射する気体噴射部(30b)と、油槽(30a)から冷却油(Y)を回収して油槽(30a)に戻す油循環部(30d)と、を備え、油循環部(30d)は、冷却油(Y)を冷却する冷却部(30j)を備える。
