Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal rolling, in particular to a static magnetic field double-roller casting and rolling machine. BACKGROUND

[0002] High-quality aluminum alloy plates, magnesium materials, copper materials and titanium materials are widely used in the fields of aerospace, rail transportation, new energy vehicles and electronic communication as light-weight and high-performance structural materials. Such materials have strict requirements on microstructure uniformity, surface quality, size precision and mechanical properties, and the manufacturing process needs to consider both efficient production and quality control. As the core of short-process metallurgical equipment, the double-roller casting and rolling machine can directly produce casting and rolling slabs with a certain thickness by injecting the metal melt into the gap between the two rotating casting and rolling rollers, using the rapid cooling and rolling action of the casting and rolling rollers to complete the solidification and plastic deformation of the melt in a very short time, thereby greatly shortening the traditional process flow and realizing efficient and low-cost manufacturing of high-quality metal materials.

[0003] However, in the process of preparing aluminum alloy plates and the like by using the above-mentioned existing double-roller casting and rolling machine, the double-roller casting and rolling machine is usually used to guide the metal melt into the gap by a simple pouring groove, relying on the natural flow of gravity, and lacks precise control of the flow rate and stability of the melt. Although some equipment attempts to introduce a magnetic field for assistance, the excitation coil is usually fixedly attached to the casting and rolling roller, the magnetic field is applied between the gap by the casting and rolling roller, and the magnetic field strength is fixed. Although this double-roller casting and rolling machine can stably control the casting and rolling flow rate of the melt in the gap in the short term, the excitation coil is difficult to stably attach to the casting and rolling roller after long-term casting and rolling roller wear, thereby causing fluctuations in the magnetic field applied to the gap, reducing the casting and rolling stability and effect of the melt, reducing the product yield, and also increasing the production cost of subsequent reprocessing.

[0004] In view of this, a double-roller casting and rolling machine for stably controlling the casting and rolling of the melt by using a magnetic field is proposed. SUMMARY

[0063] With long-term use and wear, the first casting roll 600 and the second casting roll 700 decrease in diameter, so that the roll gap increases, the fourth spring 425 is pulled by the fourth guide rod 424, so that the sleeve 423 drives the excitation coil 426 to keep in close contact with the outer wall of the second casting roll 700, ensuring the static magnetic field effect between the roll gap; at the same time, the third spring 417 pulls the third guide rod 416, so that the lubricating cylinder 414 keeps in close contact with the outer wall of the second casting roll 700, ensuring that the graphite lubricant is evenly coated on the second casting roll 700, and the positioning block 415 moves relative to the first laser range finder 418, so as to monitor the size of the second casting roll 700 in real time. With the gradual increase of the roll gap, the sealing plate 347 gradually slides on the second guide rod 345 under the pulling force of the second spring 346 and keeps in elastic contact with the outer wall of the second casting roll 700, and the gradual movement of the sealing plate 347 makes the second tooth plate 3471 mesh to drive the first gear 3484 to rotate, at this time the first single clutch 3483 acts on the first shaft 3482, so that the first shaft 3482 rotates, the third gear 3487 idles between the second single clutch 3486 and the first shaft 3482, and the second gear 3485 meshes to drive the third tooth plate 3491 to descend, so that the flow resistance plate 349 gradually descends to block the melt, gradually reduces the flow speed of the melt, avoids the situation that the melt flows too fast due to the increase of the roll gap, and ensures the effect of stable flow casting of the melt between the roll gap; wherein the lifting plate 434 drives the inclined push block 435 to rise by manually rotating the adjusting bolt 433, the first guide rod 342 is pulled by the first spring 343, and the fixed push plate 344 is translated towards the second casting roll 700, so as to ensure the elastic contact force between the sealing plate 347 and the second casting roll 700 and ensure the sealing effect;

[0064] When the distance monitored by the positioning block 415 and the first laser range finder 418 increases beyond the preset range, so that the roll gap increases beyond the error range, the two motors 520 are controlled to drive the two screw rods 530 to rotate, the first and second lifting blocks 540 and 550 are used to slide inside the rack 510, so that the first and second casting rolls 600 and 700 are close to each other and the roll gap is reduced, and the distance between the positioning disc 580 is monitored in real time by the second and third laser range finders 560 and 570, that is, the first casting roll 600 is moved upward in real time by the third laser range finder 570, and the second casting roll 700 is moved downward in real time by the second laser range finder 560, and the detection signals are transmitted to the external main controller in real time during the detection process, and when the first casting roll 600 is moved upward and the second casting roll 700 is moved downward, the distance reaches the wear size of the first and second casting rolls 600 and 700 monitored by the two first laser range finders 418, the external main controller controls the two motors to stop driving respectively, ensures the roll gap adjustment accuracy, ensures the melt casting accuracy, and the second fixed plate 431 descends with the second casting roll 700, the inclined pushing block 435 pushes the positioning plate 344 downward to move away from the second casting roll 700, the positioning plate 344 moves to reduce the pressure of the sealing plate 347 on the second casting roll 700, to avoid the increase of the extrusion force between the second casting roll 700 and the sealing plate 347 due to the descent of the second casting roll 700, to ensure the protection of the surface of the second casting roll 700, and the first tooth plate 3441 is engaged with the third gear 3487 to rotate, the second clutch acts on the first shaft 3482 to rotate, the first gear 3484 idles between the first shaft 3482 and the first clutch, the second gear 3485 engages to drive the third tooth plate 3491 to rise, so that the flow resistance plate 349 is raised to remove the blockage of the melt, to ensure that the melt can still flow stably between the roll gap after the roll gap is adjusted and reduced.
