Description

Technical Field

[0002] Currently, in metallurgical electric furnaces, the amount of refractory bricks used in different parts of the furnace body is inconsistent. During use, as the temperature inside the furnace changes, different parts of the furnace body will experience different amounts of expansion and contraction. This makes it easy for gaps to appear between the stacked refractory bricks, leading to slag and iron leakage, which seriously affects the normal operation of the metallurgical electric furnace.

Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0035] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0036] Please see Figures 1 to 4 As shown, an embodiment of the present invention provides a furnace body constraint structure, including:

[0037] The first constraint unit group is used to constrain the first opposite sides of the furnace body 1;

[0038] The second constraint unit group is used to constrain the second opposite sides of the furnace body 1. The first opposite sides and the second opposite sides enclose and form the side walls of the furnace body 1.

[0039] The first constraint unit group and the second constraint unit group each include at least two independent constraint units 2. The constraint unit 2 includes opposing groups and elastic constraint components 21. The opposing groups include columns 20 arranged on opposite sides of the furnace body 1. The columns 20 in each opposing group are connected by elastic constraint components 21 to form an elastic constraint force on the furnace body 1.

[0040] For example, the furnace body constraint structure is used to constrain a rectangular metallurgical electric furnace, which includes a long side and a short side.

[0041] In this embodiment, a first constraint unit group is set to constrain the expansion of the first opposite sides of the furnace body 1, and a second constraint unit group is set to constrain the expansion of the second opposite sides of the furnace body 1. Since both the first and second constraint unit groups include at least two independent constraint units 2, and the constraint units 2 do not affect each other, targeted constraints can be applied to different parts of the furnace body 1, thereby increasing the expansion uniformity of the furnace body 1. The column 20 is set to abut and limit the furnace body 1, while the elastic constraint component 21 provides the column 20 with an elastic force that presses it towards the center.

[0042] In an exemplary embodiment, elastic constraint components 21 are respectively disposed at the top and bottom of the column 20, and the elastic constraint components 21 in the first constraint unit group and the elastic constraint components 21 in the second constraint unit group are intersecting.

[0043] For example, the elastic constraint component 21 in the first constraint unit group and the elastic constraint component 21 in the second constraint unit group are arranged vertically.

[0044] In this embodiment, the first constraint unit group and the second constraint unit group cooperate to form a frame structure for elastically constraining the furnace body 1. The columns 20 are distributed on the four side walls of the furnace body 1 to limit the expansion of the furnace body 1 in the front and back and left and right. The elastic constraint component 21 is located below the bottom and above the top of the furnace body 1 to tighten the columns 20 on the side of the furnace body 1, so as to provide the columns 20 with an elastic force to move towards the middle.

[0045] In one exemplary embodiment, the elastic constraint component 21 includes:

[0046] Baffle 212 is installed on the outside of column 20;

[0047] Pressure plate 214 is disposed on the outside of baffle 212;

[0048] At least one elastic element 213 is provided. The elastic element 213 is installed between the baffle 212 and the pressure plate 214 to provide elastic force to the baffle 212.

[0049] A tie rod 211 is horizontally installed outside the furnace body 1, with its two ends passing through the column 20, the baffle 212, and the pressure plate 214, respectively.

[0050] The limiting member 215 is disposed on the outside of the pressure plate 214 and connected to the pull rod 211 to limit the pressure plate 214.

[0051] In this embodiment, the pressure plate 214 is configured to transmit the elastic force of the elastic element 213 to the column 20, thereby limiting the expansion of the furnace body 1. By adjusting the position of the limiting element 215 on the pull rod 211, the compression amount of the elastic element 213 can be adjusted, thereby adjusting the constraint force on the furnace body 1.

[0052] For example, the elastic element 213 is a ring compression spring or a butterfly spring, the limiting element 215 is a nut, and the nut is threadedly connected to the pull rod 211.

[0053] For example, when only one elastic element 213 is provided at the same end of the tie rod 211, the elastic element 213 is sleeved on the tie rod 211. If two or more elastic elements 213 are provided at the same end of the tie rod 211, protrusions (the height of the protrusions is set according to the elastic range of the elastic element 213) can be provided on the baffle 212 or the pressure plate 214 to support and guide the movement of the elastic element 213.

[0054] In an exemplary embodiment, each constraint unit 2 includes at least two opposing groups, and the baffles 212 located on the same side of the furnace body 1 in different opposing groups within the same constraint unit 2 are integrally formed.

[0055] In this embodiment, in order to increase the constraint strength, at least two opposing groups are set for each constraint unit 2, and each constraint unit 2 constrains a region of the furnace body 1.

[0056] In an exemplary embodiment, the constraint unit 2 includes an edge constraint unit and a middle constraint unit. The edge constraint unit is used to constrain the side position of the side wall of the furnace body 1, and the middle constraint unit is used to constrain the middle position of the side wall of the furnace body 1.

[0057] It should be noted that, since the edge of the side wall of furnace body 1 is a row of refractory bricks, and the interior of furnace body 1 is hollow, the expansion at the edge of furnace body 1 is greater than that at the center when heated without constraint. To increase the uniformity of expansion after constraint, edge constraint units are set at the edge of the side wall of furnace body 1, and intermediate constraint units are set at the center of the side wall of furnace body 1. The edge constraint units and intermediate constraint units provide different levels of constraint force to furnace body 1.

[0058] In one exemplary embodiment, the first constraint unit group includes two sets of edge constraint units, and the second constraint unit group includes two sets of edge constraint units and one set of intermediate constraint units.

[0059] For example, the first two opposite sides are the two short sides of a rectangular metallurgical electric furnace, and the second two opposite sides are the two long sides of a rectangular metallurgical electric furnace.

[0060] In one exemplary embodiment, in the same elastic constraint assembly 21, the number of elastic members 213 at the bottom of the furnace body 1 is greater than the number of elastic members 213 at the top of the furnace body 1.

[0061] It is worth noting that since the bottom of the furnace body 1 will be paved with refractory bricks and the interior of the furnace body 1 is hollow, and the top will have an opening, the expansion of the bottom of the furnace body 1 will be greater if it is not restrained. Therefore, an elastic element 213 is added to the bottom of the furnace body 1.

[0062] For example, on the same elastic constraint component 21, the number of elastic elements 213 at the bottom of the furnace body 1 is twice the number of elastic elements 213 at the top of the furnace body 1.

[0063] In one exemplary embodiment, the number of elastic members 213 near the side wall of the furnace body 1 is greater than the number of elastic members 213 in the middle of the side wall of the furnace body 1.

[0064] It is worth noting that, considering that the expansion of the edge of the furnace body 1 side wall when heated will be greater than that of the middle, the number of elastic elements 213 at the edge of the furnace body 1 side wall is greater than the number of elastic elements 213 at the middle of the furnace body 1 side wall.

[0065] For example, the number of elastic elements 213 closest to the edge of the side wall of the furnace body 1 is twice the number of elastic elements 213 at other locations.

[0066] In an exemplary embodiment, a detection element 3 is provided on the outer side wall of the furnace body 1 corresponding to each constraint unit 2. The detection element 3 is used to detect the expansion amount of the furnace body 1.

[0067] For example, by setting the detection element 3, the expansion amount of each area of ​​the furnace body 1 can be detected, thereby facilitating the adjustment of the elastic constraint force of the elastic constraint component 21 according to the expansion amount.

[0068] For example, the detection element 3 can be installed by mounting a mounting bracket on the outside of the furnace body 1.

[0069] For example, the detection element 3 is a ranging sensor.

[0070] In an exemplary embodiment of this application, a metallurgical electric furnace is also provided, including a furnace body 1 and the furnace body constraint structure described above. The furnace body 1 includes an inner layer and an outer shell. The side walls of the outer shell are independent of each other, and the furnace body constraint structure is disposed on the outer side of the outer shell.

[0071] In this embodiment, the furnace body 1 is located inside the furnace body constraint structure, which constrains the expansion of the furnace body 1. Since the four side walls of the outer shell are independent of each other, they can effectively accommodate the expansion of the furnace body 1.

[0072] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
