Description

Technical Field

[0001] This utility model belongs to the field of vertical twin-roll casting and rolling technology, and relates to a side sealing device for a vertical twin-roll casting and rolling mill. Background Technology

[0002] When the vertical twin-roll casting mill starts working, molten metal is poured directly into the molten pool formed by two rolls and side sealing plates installed on the two end faces of the rolls. The molten metal cools rapidly on the surface of the rolls and grows gradually. When the two rolls rotate relative to each other, they are squeezed together from the roll gap formed by the two rolls and finally form a thin metal strip at the exit.

[0003] The side sealing plates are held in place by external force at both ends of the casting rolls. Various types of pushing devices exist, including screw-type, pneumatic cylinder-type, and hydraulic cylinder-type clamping. The side sealing plates are subjected to complex forces, such as pressure from the roll end faces, sliding friction, lateral pressure from the molten metal, and lateral extrusion forces generated by the flattening and elongation of the solidified metal strip edges at the roll gap during rolling. Among these forces, the lateral extrusion force generated by flattening is the largest, leading to uneven forces on the upper and lower parts of the side sealing plate. Furthermore, the coefficient of friction between the side sealing plate and the roll cross-section differs from the coefficient of friction between the metal strip edges and the side sealing plate, resulting in different wear rates. Therefore, the pushing force in the upper and lower areas of the side sealing plate should be differentiated to ensure uniform wear and improve its service life.

[0004] In addition, during operation, the side sealing plate experiences wear on its contact surface with the casting roll end face, which can easily create gaps and lead to leakage, affecting product quality. Therefore, the reduction in thrust caused by the thinning of the side sealing plate due to wear needs to be compensated for in real time. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a side sealing device for a vertical twin-roll casting mill, which solves the problem that the side sealing plate will wear on the contact surface with the end face of the casting roll during the operation, which will easily create gaps, cause leakage, and affect product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The side sealing device for a vertical twin-roll casting mill includes a fixed base, a drive component, a pressure plate, a push plate, and a side sealing plate;

[0015] Optionally, according to the vertical twin-roll casting and rolling mill side sealing device of the present invention, the pressure plate, the push plate, and the back plate of the side sealing plate have a notch of the same size at the middle position of the upper part.

[0016] Optionally, according to the vertical twin-roll casting and rolling mill side sealing device of the present invention, a heat insulation layer is provided between the back plate of the side sealing plate and the side sealing plate.

[0017] Optionally, according to the vertical twin-roll casting and rolling mill side sealing device of the present invention, the driving component includes a power source, a lead screw, and two sets of sliders;

[0018] The power source is fixed to the top of the casting and rolling mill stand. The lead screw is connected to the fixed base and driven to rotate by the power source. The bottom of the lead screw has two sets of opposite threads, and two sets of sliders are respectively connected to the two sets of threads. The pressure plate has multiple rotatably connected connecting rods on the side facing the lead screw.

[0019] Optionally, according to the vertical twin-roll casting and rolling mill side sealing device of the present invention, a circular countersunk hole is opened in the middle of the pressure plate, and a pressure detection unit is installed thereon for detecting the pressure of the side sealing plate.

[0020] Optionally, according to the vertical twin-roll casting and rolling mill side sealing device of the present invention, the pressure detection unit is provided with a spherical joint, and the push plate is provided with a spherical recess, wherein the spherical joint and the spherical recess fit together.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. The structure is compact and simple, requiring little space;

The spring can compensate for the gap caused by minor wear of the side sealing plate in real time and prevent leakage.

[0024] 3. Adjust the screw-in amount of the adjusting nut to create different compressions in the upper and lower springs. When the push plate presses down, the pressure on the lower part of the side sealing plate should be greater than that on the upper part to overcome the lateral extrusion force generated by the edge extension and ensure a good seal. At the same time, this reduces the overall stress on the side sealing plate, reduces wear, and increases its service life.

[0025] 4. The pressure detection unit continuously monitors the jacking force and achieves closed-loop control with the power source, so that the jacking force of the side sealing plate is always stable within the set target value range;

[0026] 5. When the pressure plate, the push plate, and the side sealing plate back plate reciprocate, the horizontal slide groove provides further guidance and support for the pressure plate, the push plate, and the side sealing plate back plate, making the structure of this device more stable.

[0039] Example 1:

[0040] Please see Figures 1 to 6 As shown, this utility model provides a side sealing device for a vertical twin-roll casting and rolling mill, including a fixed base 3, a driving component 4, a pressure plate 7, a push plate 9, and a side sealing plate 13.

[0041] The outer wall of the fixed base 3 is vertically fixedly connected to the casting and rolling mill archway 1, and a horizontal sliding groove 3-1 is provided at the bottom.

[0042] A push plate 9 is positioned between a pressure plate 7 and a side sealing plate 13. The side of the push plate 9 facing the pressure plate 7 has at least two cylindrical bosses 9-1. The pressure plate 7 has circular holes 7-2 through which the cylindrical bosses 9-1 pass. Each cylindrical boss 9-1 has a cavity containing a spring 10, and the side sealing plate 13 is connected to the spring 10. The lower parts of both the pressure plate 7 and the push plate 9 are inserted into horizontal grooves 3-1. The cylindrical bosses 9-1 constrain the push plate 9, enabling directional movement, while the springs 10 compensate for gaps caused by minor wear on the side sealing plate 13, preventing leakage.

[0043] The present invention preferably comprises three cylindrical bosses 9-1, and the pressure plate 7 and the push plate 9 are in the form of a triangular structure. The cylindrical bosses 9-1 and the corresponding round holes 7-2 are located at the three corners of the push plate 9 and the pressure plate 7, respectively.

[0044] The drive unit 4 is located on the top of the casting and rolling mill stand 1 and drives the pressure plate 7 to move along the horizontal slide 3-1, so as to drive the side sealing plate 13 to tighten or loosen the end face of the casting and rolling roll 19.

[0045] In this embodiment, the fixed base 3 is as follows: Figure 3 As shown, it has an overall L-shaped structure. The vertical end of the fixed base 3 is fixed on the casting and rolling mill stand 1. The specific fixing method can be bolt connection or snap-fit ​​structure. The horizontal slide is located on the horizontal end of the fixed base 3. Its main function is to guide and restrict the pressure plate 7 and the push plate 9, and support the entire side sealing device 2.

[0046] The driving component 4 can be a hydraulic telescopic mechanism, with the pressure plate connected to the output end of the hydraulic telescopic mechanism, and the telescopic direction of the hydraulic telescopic mechanism is consistent with the extension direction of the horizontal slide 3-1; it can also be a cylinder, with the pressure plate connected to the output end of the cylinder, and the telescopic direction of the cylinder is consistent with the extension direction of the horizontal slide 3-1; other reciprocating motion mechanisms can also be used, so that the entire side sealing device 2 moves along the horizontal slide 3-1.

[0047] Furthermore, a guide rod 11 is provided on the side of the side sealing plate 13 facing the top push plate 9. One end of the guide rod 11 passes through the cylindrical boss 9-1, so that the side sealing plate 13 can move relative to the pressure plate 7 and the top push plate 9. The spring 10 is slidably sleeved on the guide rod 11, and its two ends abut against the inner end faces of the side sealing plate 13 and the cylindrical boss 9-1. The guide rod 11 provides support for the side sealing plate 13 and ensures uniform pressure on the side of the casting roll 19.

[0048] Furthermore, according to Figure 5As shown, one of the cylindrical bosses 9-1 has a through hole 9-3, and the others are countersunk holes 9-2. The countersunk hole 9-2 has a through hole on its end face for the guide rod 11 to pass through. Specifically, the countersunk hole 9-2 has a through hole at the center of its end face for the guide rod 11 to pass through, based on the fact that the end face of the cylindrical boss 9-1 has a surface for the spring 10 to abut against.

[0049] In this embodiment, a through hole 9-3 is provided in the circular hole of the cylindrical boss 9-1 at the bottom of the push plate 9, and a countersunk hole 9-2 is provided in the circular hole of the cylindrical boss 9-1 at the top of the push plate 9. A through hole for the guide rod 11 to pass through is provided on the end face of the countersunk hole 9-2. An adjusting nut 14 is installed at one end of the through hole 9-3 on the cylindrical boss 9-1 to adjust the compression of the spring 10. Specifically, the adjusting nut 14 is a hollow structure with external threads to be threaded to the inner wall of the through hole 9-3, and its center can allow the guide rod 11 to pass through. If the lateral extrusion force generated by the flattening and stretching of the strip edge at the roll gap is greater than the pushing force, the side sealing plate 13 is pushed open and leakage occurs. This is adjusted by rotating the adjusting nut 14. If the adjusting nut 14 is located at the bottom, the spring 10 is compressed, increasing the pressure at the bottom; if the adjusting nut 14 is located at the top, the compression of the spring 10 is reduced, decreasing the pressure at the top, and then the pressure of the side sealing plate 13 is increased to achieve sealing under different pressure conditions at the top and bottom, and to improve the life of the side sealing plate 13.

[0050] Furthermore, the pressure plate 7 is also equipped with multiple retraction bolts 18, which pass through the pressure plate 7 and are threadedly connected to the push plate 9. When the drive component 4 moves the pressure plate 7 back, the retraction bolts 18 cause the side sealing plate 13 to loosen the casting roller 19. In this embodiment, the bolt head maintains a gap of 1-2 mm with the pressure plate 7 during operation. The drive component 4 moves the pressure plate 7 towards the fixed base 3. When the pressure plate 7 touches the retraction bolts 18, continued movement will cause the side sealing plate 13 to retract, thereby separating it from the end face of the casting roller 19. At this time, the side sealing plate 13 can be replaced vertically by manual operation or by a mechanism using a clamp.

[0051] Furthermore, a side sealing plate back plate 12 is provided between the guide rod 11 and the side sealing plate 13. One side of the side sealing plate back plate 12 is provided with an installation groove 12-1 for installing the side sealing plate 13, and the other side is threadedly connected to the guide rod 11. The spring 10 abuts against the inner end face of the side sealing plate back plate 12 and the cylindrical boss 9-1, and the bottom of the side sealing plate back plate 12 is inserted into the horizontal sliding groove 3-1. When the pressure plate 7, the push plate 9 and the side sealing plate back plate 12 reciprocate, the horizontal sliding groove 3-1 guides and supports the pressure plate 7, the push plate 9 and the side sealing plate back plate 12, making the structure of this device more stable.

[0052] Furthermore, the pressure plate 7, the push plate 9, and the side sealing plate back plate 12 have the same size notch 17 at the middle of the upper part, so that the clamp can easily hold the side sealing plate 13 when it is replaced.

[0053] Example 2:

[0054] according to Figure 1 As shown, preferably, the driving component 4 includes a power source 4-1, a lead screw 4-2, and two sets of sliders 5. The power source 4-1 is an electric motor or a hydraulic motor, which can also be manually driven by a handwheel. It is fixed to the top of the casting and rolling mill stand 1. The lead screw 4-2 is connected to the fixed base 3 and is driven to rotate by the power source 4-1. The bottom of the lead screw 4-2 has two sets of opposite threads, and the two sets of sliders 5 are respectively connected to the two sets of threads. The pressure plate 7 has multiple rotatably connected connecting rods 6 on the side facing the lead screw 4-2. The connecting rods 6 are rotatably connected to the two sets of sliders 5, so that the lead screw 4-2 drives the two sets of sliders 5 to move closer or further apart, thereby driving the pressure plate 7 and the side sealing plate 13 to tighten or loosen the casting and rolling roll 19. The sliders 5 are slidably connected to the fixed base 3 on the side near the fixed base 3 and are embedded in the vertical sliding groove provided on the fixed base 3.

[0055] When the power source 4-1 drives the lead screw 4-2 to rotate, it causes the upper and lower sliders 5 to move closer to each other. Through the connecting rod 6, it pushes the pressure plate 7 towards the side sealing plate 13, which in turn pushes the push plate 9. The push plate 9 compresses the spring 10, pushing the side sealing plate back plate 12 and the side sealing plate 13 to press against the end face of the casting roller 19, thus achieving a seal. In addition, in order to ensure that the direction of movement of the pressure plate 7 is always along the horizontal slide groove 3-1, four connecting rods 6 are provided between the pressure plate 7 and the sliders 5, that is, two connecting rods 6 are connected to each group of sliders 5, and all connecting rods 6 are rotatably connected.

[0056] Example 3:

[0057] Please see Figure 2 and Figure 4 As shown, a countersunk hole 7-1 is formed in the middle of the pressure plate 7, and a pressure detection unit 8 is installed inside the countersunk hole 7-1 to detect the pressure of the side sealing plate 13. When the side sealing plate 13 is worn and slightly thinned, the thrust generated by the compression of the spring 10 can keep the side sealing plate 13 pressed against the end face of the casting roll 19 to prevent leakage. When the wear continues to increase, the pressure detection unit 8 detects that the pressure has decreased to a certain proportion, and the power source 4-1 drives the lead screw 4-2 to bring the two sliders 5 closer together, pushing the push plate 9 and increasing the pressure of the side sealing plate 13. The pressure detection unit 8 detects the pressure value, and the program controls the power source 4-1 to start, realizing closed-loop control.

[0058] Furthermore, the pressure detection unit 8 is equipped with a spherical connector 15, and the push plate 9 is equipped with a spherical recess 9-4, with the spherical connector 15 and the spherical recess 9-4 fitting together. This spherical fit ensures that even if the push plate 9 deflects, the resultant thrust generated at the contact surface remains perpendicular to the pressure detection unit 8, guaranteeing the accuracy of the thrust measurement.

[0059] Furthermore, a heat insulation layer 16 is provided between the side sealing plate back plate 12 and the side sealing plate 13. On the one hand, this can reduce heat loss at the edge of the strip, which is beneficial for rolling; on the other hand, it protects the pressure detection unit 8.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
