Description

Technical Field

[0001] This application relates to the field of metal layered composite material manufacturing technology, and in particular to a high-speed continuous casting and rolling apparatus for metal layered composite strips. Background Technology

[0002] Layered metal composites (such as copper-aluminum composites, steel-aluminum composites, and stainless steel / carbon steel composites) combine the performance advantages of each component layer and are widely used in power, electronics, transportation, and construction industries. Continuous casting and rolling is one of the various methods for producing composite strips and plates. A continuous casting and rolling mill tightly integrates the continuous casting of molten steel and the continuous rolling of steel. Its core idea is to utilize the high-temperature residual heat of the cast billet for direct rolling, thereby eliminating the traditional process of billet cooling, storage, and reheating, achieving energy saving, reduced consumption, increased efficiency, and improved product quality.

[0003] The prior art, such as the apparatus and method for continuous casting of double-flow composite metal sheets disclosed in CN106077536A, includes a first holding furnace, a second holding furnace, a first crystallizer, a second crystallizer, a first guide rod, and a second guide rod. The bottom end of the first holding furnace is connected to the first crystallizer, and the bottom end of the second holding furnace is connected to the second crystallizer. The first and second crystallizers are connected. The first and second guide rods have equal widths, with the first guide rod located below and closely fitted to the second guide rod. Both the first and second guide rods penetrate into the bottom end of the second crystallizer, and the first guide rod penetrates into the bottom end of the first crystallizer. The first and second guide rods are connected to a traction mechanism. This invention can significantly reduce the production steps of composite sheets, shorten the production cycle, improve material utilization, and produce composite sheets with lower manufacturing costs. Simultaneously, it effectively improves the bonding strength of the composite surfaces and enhances the reliability of the finished product.

[0004] The existing technology described above, when producing metal layered composite strips through continuous casting and rolling, cannot handle the situation where, after the liquid metal is continuously cast into a casting, only the surface of the casting is solidified, leaving unsolidified portions in the middle. During the continuous casting process, due to the different plasticity and yield strength of the different metals in the composite strip, deformation can easily lead to interlayer misalignment, separation, or wrinkling. From casting solidification to post-rolling cooling, the huge shrinkage difference will generate extremely high residual thermal stress at the interface, resulting in a higher defect rate for the strip. Therefore, it is necessary to provide a new device to solve the problem of high residual stress and high defect rate caused by uneven edges and loose interlayer bonding during the solidification and conveying of the composite strip. Summary of the Invention

[0005] This invention provides a high-speed continuous casting and rolling device for metal layered composite strips to improve the forming quality of the strips. The device includes a base, on the upper surface of which a casting component, a shearing component, a cooling component, and a rolling component are installed sequentially from right to left.

A conveyor roller for conveying the composite strip is provided below the processing mechanism, the shearing component, and the cooling component.

[0006] The processing mechanism includes two symmetrical portal frames fixedly connected to the upper surface of the base. The inner sides of the two portal frames are provided with clamping members for pressing the edges of the composite board strip. On the base, to the right of the clamping members, there is a side pressing member for pressing the thickness of the composite board strip.

[0011] Preferably, each of the two limiting slide frames has a support seat hinged to the right side of its opposite side, and the bottom end of the support seat is fixedly connected to the upper surface of the base. Each of the two limiting slide frames has an adjustment seat slidably connected to the left side of its opposite side via a connecting shaft, and the bottom end of the adjustment seat is fixedly connected to the upper surface of the base.

[0012] Preferably, the limiting slide frame has through slots distributed to the left and right at the position corresponding to the mounting seat. The mounting seat and the through slots on the corresponding limiting slide frame are connected by a slide rod. The front surface of the connecting shaft on the limiting slide frame is provided with a fastening nut, which can keep the limiting slide frame fixed on the adjusting seat.

[0013] Preferably, two symmetrical bidirectional hydraulic cylinders are fixedly connected to the back sides of the two side pressure plates.

Sliding blocks are fixedly connected to both ends of the lower surface of the synchronous connecting rod. The two sliding blocks are slidably connected to their corresponding portal frames in the front-back direction.

[0014] Preferably, the front and rear output ends of the telescopic rod are fixedly connected to the opposite sides of the front and rear side pressure plates, respectively.

[0015] Preferably, both ends of the opposite surfaces of the two side pressure plates are provided with arc-shaped chamfers to facilitate the sliding of the side pressure plates against the edge of the composite strip.

[0016] Preferably, the driving component includes a connecting seat rotatably connected to the front surface of the right end of the limiting slide frame on the front side, a screw rotatably connected to the left side of the connecting seat, a moving block threadedly connected to the circumferential surface of the screw, and a mounting bracket rotatably connected to the left end of the screw, the mounting bracket being fixedly connected to the upper surface of the limiting slide frame.

[0017] Preferably, a drive motor is fixedly mounted on the left side of the mounting bracket, and the output shaft of the drive motor passes through the mounting bracket and is fixedly connected to the left end of the screw.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This invention provides timely lateral restraint to both sides of the composite strip after continuous casting to maintain edge neatness and prevent warping; simultaneously, it improves the tightness of the strip through vertical rolling; by avoiding warping and increasing the tightness of the composite strip, this invention avoids the situation where a large shrinkage difference in the composite strip during continuous casting and rolling generates extremely high residual thermal stress at the interface, resulting in substandard composite strip product quality.

[0020] 2. This invention can generate different magnitudes of extrusion force on composite strips by adjusting the tilt angle of the limiting slide frame and coordinating the pressure roller at different positions on the limiting slide frame, so as to adapt to composite strips of different thicknesses.

[0021] 3. The present invention enables continuous rolling of the composite strip by driving the pressing roller to move back and forth in the left and right direction, thereby ensuring more uniform pressing of the composite strip. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] Reference Figure 1 As shown, a high-speed continuous casting and rolling device for metal layered composite strip includes a base 1. From right to left, a casting component 2, a shearing component 3, a cooling component 4, and a rolling component 5 are sequentially mounted on the upper surface of the base 1. A processing mechanism 6 for assisting in the forming of the composite strip is disposed on the upper surface of the base 1 between the casting component 2 and the shearing component 3. A conveyor roller 7 for conveying the composite strip is disposed below the processing mechanism 6, the shearing component 3, and the cooling component 4.

[0031] Reference Figure 1 , Figure 2 and Figure 3 As shown, the processing mechanism 6 includes two symmetrically arranged portal frames 61 fixedly connected to the upper surface of the base 1. The horizontal section of the portal frame 61 has a limiting groove. The two portal frames 61 are located on the front and rear sides of the conveyor roller 7, respectively. The inner side of the two portal frames 61 is provided with a clamping member 62 for pressing the edge of the composite plate. The base 1 is provided with a side pressing member 63 for pressing the thickness of the composite plate on the right side of the clamping member 62. The clamping member 62 includes two clamping rollers 621 that can move left and right and are arranged side by side. The side pressing member 63 includes two side pressing plates 631 that are arranged front and rear and whose spacing can be adjusted.

[0032] In practical use, liquid metal is first fed to the top of casting component 2. At this time, the liquid metal forms a casting through casting component 2. The formed casting is conveyed to the left by processing mechanism 6. When passing through pressure roller 621, the surface of the casting solidifies. Pressure component 62 exerts vertical pressure on the casting, making the casting more compact. At the same time, side pressure plate 631 applies side pressure to the front and rear sides of the casting, making the front and rear surfaces of the casting more regular. After passing through side pressure component 63, the casting is sheared in sections as needed when passing through shear component 3. After passing through shear component 3, the casting continues to be conveyed to the left. When passing through cooling component 4, the casting is first cooled with water and further solidified. After cooling, the casting is rolled to the required thickness by rolling component 5. The sheared casting is stacked by external equipment after rolling. The unsheared casting can be collected by external winding machine.

[0033] Reference Figure 2 , Figure 3 and Figure 4 As shown, both ends of the two clamping rollers 621 are rotatably connected to the mounting base 622. Both mounting bases 622 are slidably connected to the left and right of the limiting slide frame 623. The limiting slide frame 623 on the front side is provided with a driving component 64 that drives the clamping rollers 621 to slide left and right on the limiting slide frame 623. The upper surface of the mounting base 622 is hinged with a limiting rod. The top of the limiting rod is hinged with a connecting slider. The connecting slider is slidably connected to the horizontal section of the corresponding portal frame 61 in the left and right directions.

[0034] Reference Figure 2 , Figure 3 and Figure 4 As shown, a support seat 624 is hinged to the right side of each of the two limiting slide frames 623. The bottom end of the support seat 624 is fixedly connected to the upper surface of the base 1. An adjusting seat 625 is slidably connected to the left side of each of the two limiting slide frames 623 via a connecting shaft. The bottom end of the adjusting seat 625 is fixedly connected to the upper surface of the base 1. A through groove distributed to the left and right is provided on the limiting slide frame 623 at the position corresponding to the mounting seat 622. The mounting seat 622 and the through groove on the corresponding limiting slide frame 623 are connected by a sliding rod. A fastening nut is provided on the front surface of the connecting shaft on the limiting slide frame 623. The fastening nut can keep the limiting slide frame 623 fixed on the adjusting seat 625.

[0035] In practical use, after the liquid metal is cast into a casting through the casting component 2, it first enters below the pressure roller 621. The pressure roller 621 exerts downward roller pressure on the casting, making the casting more compact. The downward pressure exerted by the pressure roller 621 on the casting can be adjusted by adjusting the tilt angle of the limiting slide frame 623 and the position of the pressure roller 621 on the limiting slide frame 623. When adjusting the tilt angle of the limiting slide frame 623, first loosen the fastening bolt on the connecting shaft between the limiting slide frame 623 and the adjusting seat 625. At this time, the connecting shaft slides up and down on the adjusting seat 625. After the adjustment is completed, tighten the fastening bolt. Then, the driving component 64 drives the mounting seat 622 to slide on the limiting slide frame 623, and at the same time drives the pressure roller 621 to slide. When the pressure roller 621 is closer to the adjusting seat 625, the bottom end of the pressure roller 621 gradually moves downward, that is, the downward pressure exerted on the casting is greater.

[0036] Depending on the application, during continuous casting of composite strip, the clamping roller 621 can be kept stationary or it can slide back and forth in the left and right directions. When the clamping roller 621 slides back and forth, the limiting slide frame 623 remains horizontal. The driving component 64 drives the mounting base 622 to slide back and forth in the left and right directions on the limiting slide frame 623 via the slide rod. During the sliding process, the limiting rod ensures that the two clamping rollers 621 slide horizontally. When the mounting base 622 slides, the limiting rod drives the connecting slider to slide synchronously on the portal frame 61. The limiting rod and the connecting slider together limit the two clamping rollers 621 in the horizontal direction.

[0037] Reference Figure 2 , Figure 3 and Figure 5 As shown, the driving component 64 includes a connecting seat 641 rotatably connected to the front surface of the right end of the limiting slide frame 623 on the front side. A screw 642 is rotatably connected to the left side of the connecting seat 641. A moving block 643 is threadedly connected to the circumferential surface of the screw 642. A mounting bracket 644 is rotatably connected to the left end of the screw 642. The mounting bracket 644 is fixedly connected to the upper surface of the limiting slide frame 623. The rear surface of the moving block 643 is connected to the front end of the slide rod on the mounting seat 622 on the front side. A drive motor is fixedly mounted on the left side of the mounting bracket 644. The output shaft of the drive motor passes through the mounting bracket 644 and is fixedly connected to the left end of the screw 642.

[0038] In practical use, when the mounting base 622 is moved by the drive component 64, the drive motor drives the screw 642 to rotate synchronously on the mounting bracket 644 and the connecting seat 641 in both forward and reverse directions. At the same time, the moving block 643, which is threadedly connected to the screw 642, drives the mounting base 622 to move synchronously via the slide rod. Simultaneously, the connecting seat 641 is rotatably connected to the adjusting seat 625. When adjusting the tilt angle of the limiting slide frame 623, the limiting slide frame 623 drives the screw 642 to tilt synchronously via the mounting bracket 644. At this time, the screw 642 will not affect the normal angle adjustment of the limiting slide frame 623.

[0039] Reference Figure 2 and Figure 6 As shown, two symmetrical bidirectional hydraulic cylinders 632 are fixedly connected to the back of the two side pressure plates 631. A telescopic rod 633 is fixedly connected between the two bidirectional hydraulic cylinders 632. A synchronous connecting rod 634 is fixedly connected to the upper surface of the telescopic rod 633. A slider seat 635 is fixedly connected to both the front and rear ends of the lower surface of the synchronous connecting rod 634. The two slider seats 635 are slidably connected to their corresponding portal frames 61 in the front-rear direction.

[0040] Reference Figure 2 and Figure 6 As shown, the front and rear output ends of the telescopic rod 633 are fixedly connected to the opposite sides of the front and rear side pressure plates 631, respectively. The bottom end of the slider seat 635 is fixedly connected to the upper surface of its corresponding mounting seat 622. The left and right ends of the opposite surfaces of the two side pressure plates 631 are provided with arc-shaped chamfers to facilitate the sliding of the side pressure plates 631 against the edge of the composite board strip.

[0041] In practical use, after the casting passes through the pressure roller 621, it moves between the two side pressure plates 631. The distance between the two side pressure plates 631 can be adjusted by the bidirectional synchronous extension and retraction of the telescopic rod 633. The two side pressure plates 631 apply side pressure to the front and rear edges of the casting to prevent uneven edges and warping. The pressure from the pressure roller 621 further improves the compactness of the casting. At the same time, the two bidirectional hydraulic cylinders 632 allow the two side pressure plates 631 to extend and retract synchronously during movement, making the two side pressure plates 631 more stable. The rounded chamfers on the left and right sides of the two side pressure plates 631 facilitate the sliding of the side pressure plates 631 along the edge of the casting, avoiding secondary damage such as scratches or lifting.

[0042] Furthermore, when the mounting base 622 moves left and right reciprocatingly, the mounting base 622 can drive the synchronous connecting rod 634 to move synchronously via the slider seat 635. The synchronous connecting rod 634, through the telescopic rod 633, drives the two side pressure plates 631 to move left and right reciprocatingly in sync with the mounting base 622, so as to cooperate with the pressure roller 621 to press the casting. After the casting has been pressed and trimmed, it continues to move to the left for the next process.
