Title (EN) CARBURIZING DEVICE
(FR) DISPOSITIF DE CÉMENTATION AU CARBONE
(JA) 浸炭装置
Abstract:
(EN) The carburizing device (A) is provided with: a furnace body (1) for accommodating an object to be treated; multiple heaters (4a) disposed in the furnace body; multiple protective members (4b) for covering the multiple heaters; a carburizing gas supply unit (13) for supplying a carburizing gas into the furnace body; an inert gas supply unit for supplying an inert gas into the space between the heaters and the protective members; and an air supply unit for supplying burnout air into the space between the heaters and the protective members.
(FR) L'invention concerne un dispositif de cémentation au carbone (A), qui comprend : un corps de four (1) destiné à recevoir un objet à traiter; de multiples éléments chauffants (4a) disposés dans le corps de four; de multiples éléments de protection (4b) destinés à recouvrir les multiples éléments chauffants; une unité d'alimentation en gaz de cémentation au carbone (13) destinée à introduire un gaz de cémentation au carbone dans le corps de four; une unité d'alimentation en gaz inerte destinée à introduire un gaz inerte dans l'espace ménagé entre les éléments chauffants et les éléments de protection; et une unité d'alimentation en air destinée introduire de l'air de combustion dans l'espace ménagé entre les éléments chauffants et les éléments de protection.
(JA) 浸炭装置(A)は、被処理物を収容する炉体(1)と、炉体内に設けられた複数のヒータ(4a)と、複数のヒータを覆う複数の保護部材(4b)と、炉体内に浸炭ガスを供給する浸炭ガス供給部(13)と、ヒータと保護部材との隙間に不活性ガスを供給する不活性ガス供給部と、ヒータと保護部材との隙間にバーンアウト用の空気を供給する空気供給部と、を備える。
