Description

Technical Field

[0001] The present application relates to the technical field of steel rolling, and in particular to a heating furnace discharge rail base. Background Art

[0002] When the high temperature area of ​​the heating furnace used in the steel production process is lifted, the high temperature will burn the rail base under the heating furnace and deform it, which will cause the bearing seat to tilt and damage the bearing. On the other hand, the bolts used to fix the rail will also deform due to heat, and the rail will produce irreversible deformation after being stressed. The accumulated deformation will cause the rail to loosen and the bearing to misalign. Utility Model Content

[0025] The following is combined with Figure 1-2 This application is described in further detail.

[0026] The embodiment of the present application discloses a heating furnace outlet rail base.

[0027] refer to Figure 1 and Figure 2The heating furnace outlet track base includes a top plate 1, a middle plate 2 and a bottom plate 3. A plurality of mounting holes 31 are provided on the upper surface of the bottom plate 3 for bolts to pass through and fasten to the ground. The bolts used are M36 bolts. The middle plate 2 is fixedly arranged vertically on the bottom plate 3. The middle plate 2 is located in the middle of the bottom plate 3 away from another track. The top plate 1 is fixedly arranged on the top of the middle plate 2. The width of the top plate 1 is smaller than that of the bottom plate 3. The connection between the top plate 1 and the middle plate 2 is located in the middle of the top plate 1. The bottom plate 3, the middle plate 2 and the top plate 1 are all made of one-piece steel material, and the thickness ranges from 340 to 400 mm. The thickness of this embodiment is 380 mm.

[0028] By thickening the rails and reselecting the specifications of the bolts, the probability of the rails and bolts being deformed by force after being heated at the heating furnace door can be effectively reduced, thereby improving the protection effect of the bearings and bearing seats and improving the stability of the bearing seats. The selection of steel thickness can enable the rails to achieve the critical strength of stress deformation under high temperature within the required range, while also constraining costs.

[0029] refer to Figure 2 A mounting plate 41 is installed on the upper surface of the bottom plate 3 at the mounting hole 31 on the side of the middle plate 2 close to the other rail. The mounting plate 41 is fastened to the bottom plate 3 after the bolts at the mounting hole 31 pass through. A supporting rib 4 is fixedly provided on the upper surface of the mounting plate 41. The supporting rib 4 is in contact with the middle plate 2 and abuts against the top plate 1. The thickness of the supporting rib 4 gradually increases in the direction close to the middle plate 2. Two reinforcing ribs 42 are fixedly provided at the edge of the upper surface of the mounting plate 41. The reinforcing ribs 42 are fixedly connected to the supporting rib 4. The reinforcing ribs 42, the mounting plate 41 and the supporting ribs 4 are all made of metal materials and are integrally formed. In this embodiment, they are made of silicon-copper alloy steel. The supporting rib 4 near the door of the heating furnace is also located between the mounting holes 31. The same long strip plate 43 is installed on the upper surface of the mounting plate 41 located at the mounting hole 31. The long strip plate 43 has a connecting hole 431 connected to the mounting hole 31. The bolt passes through the connecting hole 431, the mounting plate 41 and the mounting hole 31 and is threadedly installed and fastened with the base. The reinforcing rib plate 42 has an abutting groove 421 abutting against the long strip plate 43. The long strip plate 43 presses the reinforcing rib plate 42 against the middle plate 2.

[0030] The mounting plate 41 is fastened to the track by means of the mounting holes 31 through which bolts are passed. Then, the support ribs 4 are fitted with the middle plate 2 to reinforce and support the connection between the middle plate 2 and the top plate 1. When the top plate 1 is heated and under pressure from the bearing seat, the top plate 1 will tend to bend between the two tracks. At this time, the support ribs are used for support, thereby reducing the probability of the track being deformed by heat. The cross-sectional shape of the support ribs 4 can effectively increase the fitting area with the middle plate 2 and can also increase its own strength. The setting of the long strips 43 can effectively install more support ribs 4 in the area near the door of the heating furnace, thereby improving the support effect on the track in this area. At the same time, the connection position setting of the bottom plate 3 and the middle plate 2 can also provide sufficient installation space for the mounting plate 41 to improve the reinforcement effect on the track.

[0031] The implementation principle of the heating furnace discharge rail base in the embodiment of the present application is: by setting the shape and thickness of the rail, and selecting the type of bolts, the heat resistance of the rail is effectively improved. At the same time, the mounting plate 41 is installed by utilizing the original mounting structure of the rail, so that the support rib plate 4 can stably support the position of the center plate 2 and the top plate 1, and the density of the support rib plate 4 is increased by setting the heating plate near the heating furnace door, thereby improving the strength of the rail at the heating furnace door position at high temperatures, thereby reducing the deformation of the rail and improving the stability of the bearing seat passing.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
