Title:
巻鉄心を焼鈍処理するための高温炉
Document Type and Number:
Japanese Patent JP2012520390
Kind Code:
A
Abstract:
A high-temperature furnace for the annealing of sheet-metal joints (4) is described, having an annealing base (2), having a support device (3), which forms a placement surface (17) for coaxially receiving a sheet-metal joint (4) with spacing above the annealing base (2), having a protective hood (6), which coaxially encloses the annealing base (2) with the support device (3), and is connected to a protective gas supply line (10) and a protective gas exhaust, made of a cylindrical jacket (7) and a cupola (16) which terminates the jacket (7) on top, having a peripheral seal (9) between the annealing base (2) and the protective hood (6), and having a heating hood (13) which encloses the protective hood (6) with spacing. In order to allow uniform annealed material heating, it is proposed that the axial jacket section of the protective hood (6) which is determined by the vertical spacing (h) of the placement surface (17) of the support device (3) from the annealing base (2) has a surface which makes up at least three-fourths of the cupola surface.
