摘要： A continuous pusher furnace includes a product carrier assembly incorporating a traveling gas barrier. The product carrier assembly comprises a plate disposed to receive product thereon and a gas barrier extending upwardly from the plate. The perimeter of the gas barrier is sized and configured to fit within a vestibule between heating chambers in the furnace with a clearance gap with the vestibule selected to increase a gas flow velocity through the vestibule sufficient to overcome a gas diffusion velocity through the vestibule in a direction opposite to the gas flow. In this manner, gas is unable to diffuse into an upstream heating chamber. In an alternative embodiment, an exhaust outlet may also be provided in the vestibule or chamber to exhaust gas from upstream and downstream heating chambers from the furnace.

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.

摘要： A shrink oven whose air volume is maintained constant as heated loads are removed and new loads are introduced, to prevent loss of heat and to improve performance. In an oven in which loads are introduced through an entry opening, move through the oven, and exit through another opening, exiting and entering loads are moved so that the rate of load displacement out of the oven at the exit is compensated by the rate of load displacement into the oven at the entry. Special arrangements prevent hot air loss around the sides of the load during the exit and introduction phases. These include close-lying passage walls above and on both sides of the openings, for limiting the air conductance of the gaps about the loads, stacking adjacent loads close together at entry and exit to minimize air leak gaps between the loads, and close positioning of the loads next to doors during opening and closing of doors.

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 shrink oven which limits loss of heated air by controlled movements of the load and the door at the opening through which the load enters or leaves the oven. By automatically stopping the load in a flow-blocking relationship to the opening as it approaches and leaves the opening, and moving the door only when the load is in such a flow-blocking relationship, loss of heated air can be substantially reduced. Preferably further arrangements enable the air volume of the oven to be maintained constant as heated loads are removed and new loads are introduced. In an oven in which loads are introduced through a side entry door, move on a conveyor through the oven, and exit through another door, exiting and entry loads are synchronized in spacing and movement so that the rate of load displacment out of the oven at the exit is compensated by the rate of load displacement into the oven at the entry. Special arrangements prevent hot air loss around the sides of the oven during the exit and introduction phases. These include close-lying passage walls above and on both sides of the doors, for limiting the air conductance of the gaps about the loads. In another oven shown, a boundary wall of the oven, a movable top as shown, moves in synchronism with an entering or leaving load to increase and decrease air volume in opposite effect to that of an entering or exiting load, respectively.
