DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 8As shown, a structural diagram of a steel rolling walking heating furnace provided by an embodiment of the present invention includes a furnace body 1, wherein support legs 11 are respectively provided on all sides of the bottom wall of the furnace body 1, a feeding port 12 is provided on one side of the furnace body 1, and a discharge port 13 is provided on the other side of the furnace body 1, and a plurality of groups of parallel distributed load-bearing beams 2 are fixedly installed in the inner cavity of the furnace body 1, and rectangular strips of steel billets 3 are placed on the surfaces of the plurality of groups of load-bearing beams 2. A plurality of groups of parallel distributed turning protrusions 21 are equidistantly provided on the surface of the load-bearing beams 2 along the traveling direction of the steel billets 3, and a feeding mechanism is provided in the inner cavity of the furnace body 1, and the feeding mechanism includes a pushing assembly 41 and an adjusting assembly 42. The pushing assembly 41 is located in the inner cavity of the furnace body 1 and between the plurality of groups of load-bearing beams 2 The adjusting component 42 is located on the side wall of the furnace body 1 and is connected to the pushing component 41. The adjusting component 42 pushes the steel billet 3 to move intermittently on the surface of the load-bearing beam 2 by cooperating with the pushing component 41. The turning protrusion 21 is used to control the steel billet 3 to roll ninety degrees when it moves on the surface of the load-bearing beam 2. The inner cavity of the furnace body 1 is provided with a cleaning mechanism that cooperates with the steel billet 3. The cleaning mechanism includes a cleaning component 51 and a driving component 52. The cleaning component 51 is located in the inner cavity of the furnace body 1 and above the load-bearing beam 2. The driving component 52 is located on the side wall of the furnace body 1 and is connected to the cleaning component 51. The driving component 52 is used to clean the oxidized waste slag on the surface of the steel billet 3 by cooperating with the cleaning component 51.

[0027] When in use, the steel billet 3 to be heated is put into the inner cavity of the furnace body 1 through the feeding port 12, and the steel billet 3 falls onto the surface of multiple groups of supporting beams 2, and the furnace body 1 heats the steel billet 3. Initially, the steel billet 3 is at one end of the supporting beam 2 close to the feeding port 12. During the heating process, the adjusting component 42 cooperates with the pushing component 41 to intermittently push the steel billet 3 on the surface of the supporting beam 2 toward the discharge port 13 for a certain distance. During the intermittent movement, when the steel billet 3 moves on the surface of the supporting beam 2 to contact the turning protrusion 21, the pushing component 41 pushes the steel billet 3 to move again, and the billet 3 will rotate ninety degrees on the surface of the supporting beam 2, so that the other side of the steel billet 3 is in contact with the supporting beam 2. This cycle is repeated, and the steel billet 3 can be controlled to roll intermittently while moving on the surface of the supporting beam 2. During the rolling process, different surfaces of the steel billet 3 can be contacted with the supporting beam 2 in turn for support, effectively improving the heating effect of the steel billet 3. When the billet 3 intermittently stops moving on the surface of the load beam 2, the cleaning assembly 51 and the driving assembly 52 cooperate to clean the oxidized rust attached to the upper surface of the billet 3. As the billet 3 intermittently rolls, the cleaning assembly 51 and the driving assembly 52 cooperate to perform a full-scale rust removal treatment on the billet 3. After the billet 3 is pushed to the discharge port 13, the billet 3 is discharged from the discharge port 13 to the outside of the furnace body 1.

[0028] like Figure 3 、 Figure 4、 Figure 6 、 Figure 7 As shown, as a preferred embodiment of the present invention, the pushing assembly 41 includes multiple groups of first horizontal columns 411 rotatably installed in the inner cavity of the furnace body 1 and located below the load-bearing beam 2, multiple groups of first push plates 412 are fixedly installed on the surface of the first horizontal column 411, and the first push plates 412 are located between two adjacent groups of load-bearing beams 2, multiple groups of second horizontal columns 413 are rotatably installed in the inner cavity of the furnace body 1 at the same height as the first horizontal columns 411, multiple groups of second push plates 414 are fixedly installed on the surface of the second horizontal columns 413, and the second push plates 414 are located between two adjacent groups of load-bearing beams 2.

[0029] The first cross column 411 positions the first push plate 412, and the second cross column 413 positions the second push plate 414. Initially, the first push plate 412 and the second push plate 414 are both below the load-bearing beam 2. When it is necessary to control the movement of the steel billet 3 on the surface of the load-bearing beam 2, the adjustment component 42 controls the first cross column 411 to reciprocate around its own axis at a certain angle, and the first cross column 411 drives the first push plate 412 to reciprocate synchronously. When the first push plate 412 rotates upward between the two groups of load-bearing beams 2, it contacts the steel billet 3 on the surface of the load-bearing beam 2. The first push plate 412 can push the steel billet 3 forward a certain distance on the surface of the load-bearing beam 2. After the steel billet 3 moves a certain distance and contacts the flipping protrusion 21, the first cross column 411 drives the first push plate 412 to rotate in the opposite direction to its original position. At this time, the adjusting component 42 controls the second horizontal column 413 to rotate back and forth at a certain angle around its own axis, and the second horizontal column 413 drives the second push plate 414 to rotate back and forth synchronously. The second push plate 414 contacts the steel billet 3 when rotating upward, and the second push plate 414 pushes the steel billet 3 to move upward again on the surface of the load-bearing beam 2 for a certain distance. When the steel billet 3 moves, the second push plate 414 applies an oblique upward thrust to the steel billet 3. The second push plate 414 cooperates with the turning protrusion 21 to control the steel billet 3 to roll ninety degrees on the surface of the load-bearing beam 2. At this time, the steel billet 3 3 passes over the turning protrusions 21 and moves again on the surface of the bearing beam 2. After the billet 3 moves forward a certain distance and contacts the next set of turning protrusions 21, the second transverse column 413 drives the second push plate 414 to rotate in the opposite direction to its original position. At this time, the adjustment component 42 controls the first transverse column 41 to rotate back and forth at a certain angle again. This cycle is repeated. The first push plate 412 cooperates with the second push plate 414 to push the billet 3 to move intermittently a certain distance on the surface of the bearing beam 2 toward the discharge port 13, and can control the billet 3 to roll intermittently while moving.

[0030] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 7As shown, as a preferred embodiment of the present invention, the adjustment component 42 includes a first guide plate 421 having one end of a first transverse column 411 extending to the outside of the furnace body 1 and fixedly installed, a first strip-shaped guide groove 422 is provided on the surface of the first guide plate 421, a first control gear disc 423 is rotatably installed on one side wall of the furnace body 1, a first guide column 424 inserted into the first guide groove 422 is provided on the surface of the first control gear disc 423 at a position deviating from the center of the circle, multiple groups of first control gear discs 423 are commonly connected to a first synchronous belt 425, a first motor 426 is fixedly installed on the outside of the furnace body 1, and a first transmission gear disc 427 is fixedly installed on the output shaft of the first motor 426, and the first transmission gear disc 427 is meshed and connected with a group of first control gear discs 423, One end of the second horizontal column 413 extends to the other side outside the furnace body 1 and is fixedly installed with a second guide plate 428. A strip-shaped second guide groove 429 is provided on the surface of the second guide plate 428. A second control gear disc 4210 corresponding to the second guide plate 428 is rotatably installed on the other side wall of the furnace body 1. A second guide column 4211 inserted into the second guide groove 429 is provided on the surface of the second control gear disc 4210 at a position deviating from the center of the circle. Multiple groups of second control gear discs 4210 are commonly connected to a second synchronous belt 4212. A second motor 4213 is fixedly installed on the outside of the furnace body 1. A second transmission gear disc 4214 is fixedly installed on the output shaft of the second motor 4213. The second transmission gear disc 4214 is meshed and connected with a group of second control gear discs 4210.

[0031] During use, the first motor 426 drives the first transmission sprocket 427 to rotate. The first transmission sprocket 427 engages with the first control sprocket 423 to drive a group of first control sprockets 423 to rotate. The first control sprockets 423 cooperate with the first synchronous belt 425 to drive multiple groups of first control sprockets 423 to rotate synchronously. The first control sprockets 423 drive the first guide posts 424 to rotate synchronously. The rotating first guide posts 424 cooperate with the first guide grooves 422 to control the first guide plate 421 to reciprocate around the first transverse post 411 at a certain angle. The first guide plate 421 controls the first transverse post 411 to reciprocate around its own axis at a certain angle. After the first transverse post 411 and the first push plate 412 have reciprocated once, the first motor 426 stops. At this time, the second motor 4213 drives the second transmission gear plate 4214 to rotate, and the second transmission gear plate 4214 engages with a group of second control gear plates 4210 for transmission, which can drive the second control gear plates 4210 to rotate. The second control gear plates 4210 cooperate with the second synchronous belt 4212 to drive multiple groups of second control gear plates 4210 to rotate synchronously, and the second control gear plates 4210 drive the second guide posts 4211 to rotate synchronously. The second guide posts 4211 cooperate with the second guide grooves 429 to drive the second guide plates 428 to reciprocate around the second horizontal column 413 at a certain angle. The second horizontal column 413 drives the second push plate 414 to reciprocate synchronously. After the second horizontal column 413 and the second push plate 414 rotate back and forth once, the second motor 4213 stops running. At this time, the first motor 426 is controlled to start running again. This cycle is repeated, and the first horizontal column 411 and the second horizontal column 413 can be controlled to reciprocate intermittently.

[0032] like Figure 3 、 Figure 8 As shown, as a preferred embodiment of the present invention, the cleaning assembly 51 includes multiple groups of top rods 511 rotatably installed in the inner cavity of the furnace body 1 and located above the load-bearing beam 2, multiple groups of support rods 512 are fixedly installed on the surface of the top rod 511, and the multiple groups of support rods 512 are commonly fixedly installed with a cleaning plate 513 at one end away from the top rod 511, and multiple groups of evenly distributed rust removal brushes 514 are arranged on the surface of the cleaning plate 513.

[0033] The push rod 511 and the support rod 512 cooperate with each other to support and position the cleaning plate 513 and the rust removal brush 514. Initially, the cleaning plate 513 and the rust removal brush 514 are directly above the push rod 511. After the billet 3 moves a certain distance on the surface of the load-bearing beam 2, the billet 3 is relatively stationary on the surface of the load-bearing beam 2. At this time, the driving assembly 52 controls the push rod 511 to rotate around its own axis in the inner cavity of the furnace body 1. The push rod 511 and the support rod 512 cooperate with each other to drive the cleaning plate 513 and the rust removal brush 514 to rotate synchronously in the inner cavity of the furnace body 1. When the rust removal brush 514 rotates to the lowest point, it can effectively clean the oxidized rust attached to the upper surface of the billet 3. As the billet 3 intermittently rolls 90 degrees, the rust removal brush 514 can comprehensively clean the oxidized rust attached to each surface of the billet 3.

[0034] like Figure 1 、 Figure 3 、 Figure 8 As shown, as a preferred embodiment of the present invention, the driving assembly 52 includes a synchronous gear disc 521 with one end of a push rod 511 extending to the outside of the furnace body 1 and fixedly installed, and multiple groups of synchronous gear discs 521 are commonly connected with a synchronous toothed belt 522. A third motor 523 is fixedly installed on the outside of the furnace body 1, and the output shaft of the third motor 523 is connected to a group of push rods 511.

[0035] When the first motor 426 and the second motor 4213 stop running, the steel billet 3 is at rest on the surface of the load beam 2. The third motor 523 is then started, driving a set of ejector pins 511 to rotate, which in turn drives the synchronous geared disc 521 to rotate. The multiple sets of synchronous geared discs 521 cooperate with the synchronous toothed belt 522 to drive the multiple sets of ejector pins 511 to rotate synchronously within the furnace body 1.

[0036] like Figure 2 、 Figure 3 、 Figure 5 As shown, as a preferred embodiment of the present invention, one end of the load-bearing beam 2 is arranged to be inclined downward and pass through the discharge port 13 , and a placement rod 6 is fixedly installed on one end of the load-bearing beam 2 located outside the discharge port 13 .

[0037] When the steel billet 3 is pushed to the surface of the load-bearing beam 2 near the discharge port 13 , the steel billet 3 automatically slides out on the surface of the load-bearing beam 2 and falls on the surface of the placement rod 6 , and the staff can conveniently take the steel billet 3 .

[0038] like Figure 1 、 Figure 3 As shown in FIG. 1 , as a preferred embodiment of the present invention, the bottom wall of the furnace body 1 is provided with a funnel-shaped structure, and a collecting cylinder 7 is fixedly installed on the bottom wall of the furnace body 1. The collecting cylinder 7 can collect the cleaned oxidized slag.

[0039] like Figure 3 As shown, as a preferred embodiment of the present invention, a feed plate 8 located outside the feeding port 12 is fixedly mounted on the surface of the furnace body 1 .

[0040] The working principle of the present invention is: when in use, the steel billet 3 to be heated is fed into the inner cavity of the furnace body 1 through the feeding port 12, and the steel billet 3 falls onto the surface of multiple groups of load-bearing beams 2. The furnace body 1 heats the steel billet 3. Initially, the steel billet 3 is at one end of the load-bearing beam 2 close to the feeding port 12. During the heating process, the first motor 426 drives the first transmission gear disc 427 to rotate, and the first transmission gear disc 427 engages with the first control gear disc 423 for transmission, thereby driving a group of first control gear discs 423 to rotate. The first control gear disc 423 cooperates with the first synchronous belt 425 to drive multiple groups of first control gear discs 423 to rotate synchronously. The first control gear disc 423 drives the first guide column 424 to rotate synchronously. The rotating first guide column 424 cooperates with the first guide groove 422 to control the first guide plate 421 to reciprocate around the first cross column 411 at a certain angle. The first guide plate 421 controls the first cross column 411 to reciprocate synchronously around its own axis at a certain angle. After the first horizontal column 411 and the first push plate 412 rotate back and forth once, the first motor 426 stops running. At this time, the second motor 4213 drives the second transmission gear plate 4214 to rotate, and the second transmission gear plate 4214 engages with a group of second control gear plates 4210 for transmission, which can drive the second control gear plates 4210 to rotate. The second control gear plates 4210 cooperate with the second synchronous belt 4212 to drive multiple groups of second control gear plates 4210 to rotate synchronously, and the second control gear plates 4210 drive the second guide posts 4211 to rotate synchronously. The second guide posts 4211 cooperate with the second guide grooves 429 to drive the second guide plates 428 to reciprocate around the second horizontal column 413 at a certain angle. The second horizontal column 413 drives the second push plate 414 to reciprocate synchronously. After the second horizontal column 413 and the second push plate 414 rotate back and forth once, the second motor 4213 stops running. At this time, the first motor 426 is controlled to start running again. This cycle is repeated, and the first horizontal column 411 and the second horizontal column 413 can be controlled to reciprocate intermittently.

[0041] The first horizontal column 411 drives the first push plate 412 to rotate back and forth synchronously. When the first push plate 412 rotates upward between the two groups of load-bearing beams 2, it contacts the steel billet 3 on the surface of the load-bearing beam 2. The first push plate 412 can push the steel billet 3 to move forward a certain distance on the surface of the load-bearing beam 2. After the steel billet 3 moves a certain distance and contacts the material-turning protrusion 21, the first horizontal column 411 drives the first push plate 412 to rotate in the opposite direction to its original position. When the first push plate 412 and the second push plate 414 are in contact with each other, the first push plate 412 and the second push plate 414 can push the billet 3 to move a certain distance on the surface of the load-bearing beam 2 toward the discharge port 13, and can control the billet 3 to roll intermittently while moving. During the rolling process, different surfaces of the steel billet 3 can be brought into contact with the bearing beam 2 in sequence for support, thereby effectively improving the heating effect of the steel billet 3 .

[0042] When the steel billet 3 intermittently stops moving on the surface of the load beam 2, the third motor 523 is activated, driving a set of push rods 511 to rotate. The push rods 511 then drive the synchronous geared disc 521 to rotate. The multiple sets of synchronous geared discs 521 cooperate with the synchronous toothed belt 522 to drive the multiple sets of push rods 511 to rotate synchronously within the furnace body 1. The push rods 511 cooperate with the support rods 512 to drive the cleaning plate 513 and rust removal brush 514 to rotate synchronously within the furnace body 1. When the rust removal brush 514 reaches its lowest position, it effectively removes oxidized rust from the surface of the steel billet 3. As the steel billet 3 intermittently rotates 90 degrees, the rust removal brush 514 comprehensively removes oxidized rust from all surfaces of the steel billet 3.

[0043] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
