Description

Technical Field

[0001] The present application relates to the technical field of pusher-steel heating furnaces, and in particular to a sealing structure of a pusher-steel heating furnace. Background Art

[0002] A pusher-type heating furnace is a continuous heating furnace that uses a pusher to move the billet inside the furnace. When heating the billet, the pusher-type heating furnace usually transports the billet to the inlet of the pusher-type heating furnace, and then the pusher pushes the billet into the interior of the pusher-type heating furnace. During production, due to the need to continuously push steel into the interior of the pusher-type heating furnace, the door of the pusher-type heating furnace is open, and the cold air outside the furnace can enter the interior of the furnace along with the billet, reducing the temperature inside the furnace, but also causing waste of fuel in the furnace. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0024] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended only to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0026] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense.

[0027] Example

[0028] like Figure 1-4 As shown, the sealing structure of the push-steel heating furnace described in the embodiment of the present application is installed at the door 1 of the push-steel heating furnace. The sealing structure 2 of the push-steel heating furnace includes several support members 4 installed at the upper end of the push-steel heating furnace 3 and flexible shielding members 5 installed on the support members 4. The flexible shielding members 5 are used to shield the door 1 of the push-steel heating furnace. When the pusher pushes the steel billet 7 into the interior of the push-steel heating furnace 3, the flexible shielding members 5 are deformed by the force, so as not to affect the steel feeding. Since there are multiple flexible shielding members 5, the flexible shielding members 5 that are not in contact with the steel billet 7 will still shield the door 1 of the push-steel heating furnace, thereby maximizing the shielding effect at the door 1 of the push-steel heating furnace, reducing the heat loss inside the push-steel heating furnace 3, effectively improving the heating efficiency inside the push-steel heating furnace 3, and improving the heating quality of the steel billet 7.

[0029] In this embodiment, the upper end of the support member 4 is fixedly connected to the push-steel heating furnace 3, and the lower end of the support member 4 has a bending portion 6. The flexible shielding member 5 can be detachably installed on the bending portion 6, which is convenient for replacing the damaged flexible shielding member 5 separately.

[0030] In this embodiment, the bending portion 6 is a U-shaped or V-shaped structure, which is easy to manufacture and shape.

[0031] In this embodiment, the flexible shielding member 5 is a chain, which is easy to install and can facilitate the operator on the steel-pushing side to see the production situation inside the steel-pushing heating furnace 3 more clearly.

[0032] In this embodiment, the upper end of the flexible shielding member 5 is lower than the upper end of the bent portion 6 , thereby reducing the possibility of the flexible shielding member 5 slipping off.

[0033] In this embodiment, the support member 4 is welded to the furnace body 3 of the pusher type heating furnace, which facilitates the installation of the support member 4 .

[0034] In this embodiment, the plurality of support members 4 are linearly distributed, and the distance between two adjacent support members 4 is equal, so that support members 4 and flexible shielding members 5 of the same specifications can be used.

[0035] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
