Abstract
Description
Technical Field
[0001] The utility model relates to an on-line device for removing cutting nodules of continuous casting billets, belonging to the technical field of finishing of continuous casting rectangular billets. Background Art
[0002] Cutting is an important part of continuous casting production. After the flame cutting machine cuts the ingot, a cutting nodule will be formed on the lower surface of the end. The cutting nodule will affect the biting process of steel rolling, affect the quality of the rolled steel end, and endanger the casting machine. At present, the cutting nodule is removed manually, specifically by workers using a chisel or cutting gun to remove it next to the ingot, which is time-consuming and laborious, and the working environment is harsh, and there is a risk of burns and heatstroke to the workers. If the ingot is delivered hot, if the cutting nodule needs to be removed at this time, it will not only threaten the safety of the workers, but also cause the temperature of the ingot to drop, affecting the quality. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide an online device for removing cutting bumps of continuous casting billets in view of the above-mentioned prior art, which can remove the cutting bumps of flame cutting online, thereby ensuring the quality of the billet ends, reducing the risks of manual operations, and improving the turnover speed of the billets.
[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: an online device for removing cutting nodules of continuous casting billets, comprising a scraper, wherein the scraper is arranged on a lifting mechanism, and the lifting mechanism drives the scraper to perform lifting and lowering movements, driving the scraper close to the lower surface of the billet, and then the scraper removes the cutting nodules on the lower surface of the billet; or driving the scraper away from the lower surface of the billet; a collecting hopper is provided under the scraper, and the collecting hopper collects the removed cutting nodules.
[0005] The lifting mechanism includes a scraper frame, which is fixed to the casting roller. A worm gear transmission is arranged inside the scraper frame. The worm in the worm gear transmission is arranged vertically, and a scraper is arranged on the top of the worm. The worm gear transmission is driven to move, which drives the scraper to move up and down.
[0006] A motor support frame is provided on the side of the scraper frame, a motor is arranged on the motor support frame, a reducer is arranged on the output shaft of the motor, and the output shaft of the reducer is fixedly connected to the central shaft of the worm gear through a coupling.
[0007] A grating is also provided, which is arranged above the casting roller and is connected to the control system signal.
[0008] Compared with the prior art, the advantages of the utility model are: an online device for removing cutting nodules of continuous casting billets, which can remove cutting nodules caused by flame cutting online, reducing the process of removing cutting nodules offline and improving the turnover rate of casting billets; it not only ensures the quality of the ends of casting billets, but also reduces the risks of manual operations. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic diagram of an online device for removing cutting bumps of continuous casting slabs according to an embodiment of the utility model;
[0010] In the figure, 1 is a motor support frame, 2 is a motor, 3 is a reducer, 4 is a coupling, 5 is a scraper frame, 6 is a worm gear transmission, 7 is a scraper, 8 is a grating, 9 is a collecting hopper, 10 is a control system, and 11 is a flange. DETAILED DESCRIPTION
[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] like Figure 1 As shown, an online device for removing cutting nodules of continuous casting billets in this embodiment includes a scraper 7, which is arranged on a lifting mechanism. The lifting mechanism drives the scraper 7 to move up and down, driving the scraper 7 close to the lower surface of the billet. There is a speed difference between the billet running on the billet roller and the scraper, forming a shear force, and then the scraper quickly removes the cutting nodules on the lower surface of the billet; or drives the scraper away from the lower surface of the continuous casting billet, waiting for the next operation. A collecting hopper 9 is arranged below the scraper 7, and the collecting hopper 9 collects the removed cutting nodules.
[0013] The lifting mechanism includes a scraper frame 5, which is fixed to the casting roller. A worm gear transmission 6 is provided inside the scraper frame 5. The worm in the worm gear transmission 6 is arranged vertically. A flange 11 is provided on the top of the worm. The scraper 7 is fixed to the flange 11 by bolts. A motor support frame 1 is provided on the side of the scraper frame 5. A motor 2 is provided on the motor support frame 1. A reducer 3 is provided on the output shaft of the motor 2. The output shaft of the reducer 3 is fixedly connected to the central axis of the worm gear through a coupling 4. The worm and the worm gear are meshed. The motor 2 and the reducer 3 drive the worm gear in the worm gear transmission 6 to rotate, driving the worm to perform lifting and lowering movements, so that the scraper is lifted and lowered synchronously.
[0014] A grating 8 is provided above the billet roller table, and the grating 8 is connected to the control system 10 by signal. When the billet reaches the specified position range after cutting, the grating is triggered, and the control system controls the motor to rotate forward or reverse, driving the scraper to rise or fall.
[0015] The output speed of the above reducer is ≤30r / min, and the lifting stroke of the worm gear transmission is about 400mm.
[0016] The scraper is made of high-chromium and high-tungsten W18Cr4 steel with a beveled edge, with a thickness of about 50 mm, a width of about 300 mm, and a bevel angle of about 30°.
[0017] The steps for removing the cutting nodules of the casting slab are as follows:
[0018] 1. After the billet is cut, it is transported to the designated position through the billet roller. The grating sends a signal to the control system, the motor is powered on, driving the reducer to rotate, so that the worm gear transmission operates, and the scraper rises to the lower surface of the billet.
[0019] 2. The billet runs along the billet roller, and the billet and the scraper move towards each other, forming a shear force. The scraper cuts off the cutting nodules in the high temperature state from the billet and collects them in the collection hopper;
[0020] 3. After cutting, the motor reverses to drive the scraper down and wait for the next operation.
[0021] The equipment has been tested in production applications and can basically remove the cutting nodules on the lower surface of the ingot, reducing the process of removing the cutting nodules offline and improving the turnover rate of the ingot. The present application can remove the cutting nodules of flame cutting online, which not only ensures the quality of the ingot end, but also reduces the risk of manual operation.
[0022] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
