Abstract
The utility model relates to a furnace door with high sealing property. The furnace door comprises a water-cooling door frame, a furnace door, an air cylinder, a connecting rod and a pressing shaft, and is characterized in that the water-cooling door frame is connected with the furnace door in an embedded manner, the pressing shaft is connected with the air cylinder by the connecting rod, and the connecting rod drives the pressing shaft to rotate; the water-cooling door frame is provided with a sealing groove. According to the furnace door, the water-cooling door frame is connected with the furnace door in an embedded manner, and the furnace door and the furnace body are sealed tightly, therefore, the furnace door has the advantages of preventing from flaring up during production, reducing heat loss and reducing the oxidation rate of a steel plate.
Description
Technical field
The utility model relates to a kind of annealing fire door, especially a kind of door of annealing furnace of high leakproofness.
Background technology
Roller hearth heat-treated furnace is the processing unit generally using in industries such as ferrous metallurgy, non-ferrous metal and machineries, because material two sides is heated, heating comparatively fast, more even, be widely used in the thermal treatment process such as normalizing, annealing, quenching, tempering.The sealing of roller bottom type annealing furnace fire door is key and difficult point, seal form has a variety of at present, at the initial stage of operation, sealing still can, but after operation for some time, the distortion causing due to high temperature scaling loss usually causes poorly sealed, in production run, very easily burn with anger, make thermosteresis strengthen and easily cause the oxidation of steel plate.
Summary of the invention
The purpose of this utility model is to provide a kind of high leakproofness fire door, and water-cooled doorframe and fire door are inserted to link together, and fire door and furnace sealing are tight, has advantages of the oxidation ratio that can avoid burning with anger, reduce thermosteresis in production run, reduce steel plate.
For achieving the above object, the utility model is realized by the following technical solutions:
A high leakproofness fire door, comprises water-cooled doorframe, fire door, cylinder, connecting rod, compression axis, it is characterized in that, described water-cooled doorframe and fire door is inserted links together, and compression axis is connected with cylinder by connecting rod, and connecting rod drives compression axis rotation.
Described water-cooled doorframe is provided with sealing groove.
In described sealing groove, be provided with sealing fiber.
Described connecting rod has three angles.
Compared with prior art, the beneficial effects of the utility model are:
High leakproofness fire door, the oxidation ratio that can avoid burning with anger, reduce thermosteresis in production run, reduces steel plate.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in Figure 1, high leakproofness fire door, by water-cooled doorframe 1, fire door 2, compression axis 3, cylinder 4, furnace door lifting device 5, furnace door guide rail 6, sealing fiber 7, fire door thermal insulating warm-keeping layer 8 and connecting rod 9, formed, water-cooled doorframe 1 links together with fire door 2 is inserted, compression axis 3 is connected with cylinder 4 by connecting rod 9, and connecting rod 9 drives compression axis 3 rotations.Water-cooled doorframe 1 is provided with sealing groove, is provided with sealing fiber 7 in sealing groove, and connecting rod has three angles, and when fire door 2 is releasing orientation, connecting rod 9 becomes-7.4 ° with level; When fire door 2 contacts with sealing fiber 7, connecting rod 9 becomes 25.2 ° with level; When fire door 2 compresses with sealing fiber 7, connecting rod becomes 37.8 ° with level, until compress with sealing fiber 7.Open door state: obtain after door opened instruction, cylinder 4 starts action and rotates with compression axis 3 by connecting rod 9, to fire door 2 and 7 disengagings of sealing fiber, make fire door 2 in releasing orientation, then furnace door lifting device 5 starts to start, make fire door 2 slide to fire door 2 open sites along furnace door guide rail 6, so far one of fire door 2 has completed from being closed to the work period of unlatching.
