    摘要: A seal assembly of the invention located on entrance and exit sides of a heat treating furnace for a metallic strip. The seal assembly is formed of a housing having a furnace wall and a side plate, a seal sheet fixed at one end to the side plate and supported in place with flexibility, an elastic seal pad fixed to a surface of the seal sheet, and an elastic rotating roll held by the furnace wall at longitudinal ends and pressed against the elastic seal pad and a metallic strip to be treated. The elastic seal pad has a surface formed of a material with a limit oxygen index LOI of 26 or more and a hardness of 10 to 50 as measured according to JIS S6050. Also, a plurality of pressure applying mechanisms is attached to the side plate. Each pressure applying mechanism includes a holder fixed to each sleeve of the furnace wall, a pressure applying member situated in the holder to apply pressure to the seal sheet in the furnace, a coil spring situated in the holder for urging the pressure applying member to the furnace, and a bolt threadably engaging a thread of the holder for urging the coil spring toward the furnace. The elastic seal pad can closely contact the elastic rotating roll by the plurality of pressure applying mechanisms.

    摘要: The sealing apparatus of the present invention is intended to enhance the sealing performance and to reduce the rotation loads at the end surfaces of elastic rolls. A sealing apparatus 20 is provided to hermetically seal the inlet/outlet of a bright annealing furnace 22, through which a metal strip 21 is passed. Since the metal strip 21 is held between a pair of elastic rolls 23 on both sides of the strip, the metal strip can be passed through while hermetic sealing is maintained. A covering member 34 and an end surface sealing member 39 made of elastic materials are disposed between the end surface of the elastic roll 23 and the side wall 26 of a casing 25 to attain reliable sealing. A first supporting member 35, a second supporting member 36. an outer bearing 37 and inner bearings 38 made of rigid materials are disposed between the covering member 34 and the end surface sealing member 39 to reduce the rotation loads of the rolls.

    摘要: A sealing apparatus securely seals the inlet and outlet of an atmosphere heat treatment furnace. A pair of elastic rolls 26 and a pair of additional elastic rolls 26 hold a metal strip so as to seal the inlet and outlet of the atmosphere heat treatment furnace which continuously performs bright annealing of the metal strip in a combustible atmosphere gas including hydrogen gas. A pair of intermediate rolls are disposed between the elastic rolls and the additional elastic rolls. The outer peripheral surface of the elastic roll is sealed by a seal plate. By multi-stage sealing, the outside air can be shut off securely from the atmosphere of the furnace.
