Machining platform for tundish production

Abstract

The utility model discloses a machining platform for tundish production. The machining platform comprises a tundish body and a feeding pipe. By means of the design of multiple buffering, after molten steel is discharged into the tundish body through the flow guide plate, the flow speed of the molten steel can be reduced through the inclined design of the buffering plate, and the molten steel subjected to speed reduction is discharged to the position of the flow guide plate through the guiding effect of the backflow plate; in this way, the decelerated molten steel forms convection to the molten steel subsequently discharged into the tundish body, and the impact force generated when the molten steel is discharged into the tundish is greatly reduced. By using the motor, the plugging plate can be opened, so that a worker can conveniently carry out follow-up cleaning work on the interior of the tundish body, in addition, when the impact force of molten steel in the tundish body is in the buffering process, the worker can coincide the discharging hole and the discharging pipe through using the connecting rod, and therefore the discharging hole and the discharging pipe can be conveniently cleaned. Therefore, molten steel in the middle body is discharged into the next process through the discharging pipe.

Description

Technical Field

[0001] The utility model relates to the technical field of tundish devices, in particular to a processing platform for tundish production. Background Art

[0002] The vacuum induction melting furnace is an important smelting equipment for smelting high-temperature alloys, deep-sea corrosion-resistant alloys, nuclear power materials, precision alloys and high-requirement special steels. The tundish is one of its components. The tundish is a refractory container used to receive the molten steel poured from the ladle and then distribute it to various crystallizers through the water outlet of the tundish. The tundish plays a vital role in improving steel production and quality.

[0003] The patent, published under the publication number "CN219818014U," is titled "A Tundish Processing Device." The device described in this publication merely cushions the impact of molten steel by providing baffles and inclined plates, but fails to recirculate the molten steel within the tundish. This inability to circulate the molten steel within the tundish reduces its impact-absorbing effect. Based on this, the present invention designs a tundish production processing platform to address this issue. Utility Model Content

[0004] The purpose of the utility model is to provide a processing platform for tundish production to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a processing platform for tundish production, comprising a tundish body and a feed pipe, the feed pipe being fixedly passed through the upper left end of the outside of the tundish body, a buffer assembly being arranged inside the tundish body, the buffer assembly comprising a guide plate fixedly arranged on the left side of the inside of the tundish body, a buffer plate fixedly arranged on the right side of the guide plate being fixedly connected to the tundish body, a return plate fixedly arranged on the right side of the buffer plate being fixedly connected to the tundish body, a bracket fixedly arranged on the right side of the return plate being fixedly connected to the tundish body, a cross section of the bracket being T-shaped, a combined state of the guide plate and the buffer plate being V-shaped, and a cross section of the return plate being semicircular.

[0006] Furthermore, a mounting tube is fixedly passed through the right side of the exterior of the buffer plate, and the right end of the mounting tube is fixedly passed through the bracket and the tundish body in turn.

[0007] Furthermore, a blocking block is slidably connected to the right side of the installation tube, and a discharge hole is integrally provided inside the blocking block. The discharge hole is a through hole design, and the discharge hole is designed in an L-shaped direction.

[0008] Furthermore, a connecting rod is rotatably passed through the upper right end of the installation tube, the connecting rod is threadedly passed through the blocking block, and a discharge pipe is fixedly passed through the right side of the bottom of the installation tube.

[0009] Furthermore, the front and rear sides of the top of the inner top of the tundish body are connected with rotating rods, and the outer fixed sleeve of the rotating rod is provided with a sealing plate.

[0010] Furthermore, a worm gear is provided on the fixed sleeve on the right side of the outer side of the rotating rod, and a motor with forward and reverse rotation and self-locking functions is fixed on the upper right side of the outer side of the tundish body.

[0011] Furthermore, a worm is fixedly provided at the rear end of the motor, and the worm is designed to be in gear meshing with the worm wheel, and the end of the worm away from the motor is connected to the tundish body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model adopts a multiple buffering design. When the molten steel is discharged into the interior of the tundish body through the guide plate, the flow rate of the molten steel is first slowed down by the inclined design of the buffer plate. The slowed-down molten steel is then discharged to the position of the guide plate through the guiding effect of the reflux plate. In this way, the slowed-down molten steel forms convection with the molten steel subsequently discharged into the tundish body, thereby greatly reducing the impact force of the molten steel discharged into the tundish.

[0015] 2. The utility model can open the sealing plate by using a motor, thereby facilitating the staff to carry out subsequent cleaning work on the inside of the ladle body. In addition, when the impact force of the molten steel inside the ladle body is in the process of buffering, the staff can use the connecting rod to overlap the discharge hole and the discharge pipe, thereby discharging the molten steel inside the tundish body through the discharge pipe into the next process.

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figure 1 、 Figure 2 、 Figure 4 As shown, the device includes a tundish body 1 and a feed pipe 2. The feed pipe 2 is fixedly passed through the upper left end of the outside of the tundish body 1. A buffer assembly 3 is provided inside the tundish body 1. The buffer assembly 3 includes a guide plate 301 fixed on the left side of the inside of the tundish body 1, a buffer plate 302 fixed on the right side of the guide plate 301 is fixedly connected to the tundish body 1, a return plate 303 fixed on the right side of the buffer plate 302 is fixedly connected to the tundish body 1, a bracket 304 fixed on the right side of the return plate 303 is fixedly connected to the tundish body 1, the cross section of the bracket 304 is T-shaped, the combined state of the guide plate 301 and the buffer plate 302 is V-shaped, and the cross section of the return plate 303 is semicircular.

[0027] First, the molten steel from the previous process is discharged from the discharge pipe 8 into the tundish body 1. Guided by the guide plate 301, the molten steel flows from top to bottom into the left end of the buffer plate 302. The buffer plate 302 guides the impacting molten steel from bottom to top to the position of the return plate 303. In this way, the impact force of the molten steel is initially buffered. The guidance of the return plate 303 causes the molten steel to flow back to the position between the guide plate 301 and the buffer plate 302. At this time, the molten steel discharged from the feed pipe 2 into the tundish body 1 and the molten steel in the return flow are in a state of convection, thereby buffering the impact force of the molten steel for a second time. In this way, the buffering effect of the impact force of the molten steel is greatly improved. The bracket 304 not only strengthens the stability of the installation of the return plate 303 and the tundish body 1, but also improves the stability of the return plate 1 in guiding the molten steel to the position between the guide plate 301 and the buffer plate 302.

[0028] Example 2

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 As shown, a mounting tube 4 is fixedly passed through the right side of the buffer plate 302, and the right end of the mounting tube 4 is fixedly passed through the bracket 304 and the tundish body 1 in sequence. A blocking block 5 is slidably connected to the right side of the inside of the mounting tube 4. A discharge hole 6 is integrally provided inside the blocking block 5. The discharge hole 6 is a through hole design, and the discharge hole 6 is L-shaped. A connecting rod 7 is rotatably passed through the upper right end of the mounting tube 4, and the connecting rod 7 is threadedly passed through the blocking block 5. A discharge tube 8 is fixedly passed through the right side of the bottom of the mounting tube 4, and the front and rear sides of the top of the inside of the tundish body 1 are connected with rotating Rod 9, the external fixed sleeve of the rotating rod 9 is provided with a sealing plate 10, the external right fixed sleeve of the rotating rod 9 is provided with a worm gear 11, and the upper right end of the external side of the tundish body 1 is fixed with a motor 12 with forward, reverse and self-locking functions, and the rear end of the motor 12 is fixed with a worm 13. The worm 13 and the worm gear 11 are designed to be in gear meshing design, and the end of the worm 13 away from the motor 12 is connected to the tundish body 1, the front end of the worm gear 11 and the worm 13 are designed to be in left-thread gear meshing design, and the rear end of the worm gear 11 and the worm 13 are designed to be in right-thread gear meshing design.

[0030] According to the operation mode in Example 1, when the molten steel is in the process of convection buffering, the staff can rotate the connecting rod 7 forward, and through the action of the threaded transmission of the connecting rod 7 and the blocking block 5, the blocking block 5 is moved along the right direction of the mounting tube 4, thereby making the discharge hole 6 and the discharge pipe 8 overlap with each other. In addition, according to the actual use situation, the staff can adjust the overlap range of the discharge hole 6 and the discharge pipe 8 to control the flow of the buffered molten steel through the mounting tube 4, the discharge hole 6, and the discharge pipe 8 into the next tool. When the device is finished using, the staff can Turn on the forward rotation function of the motor 12, and the motor 12 drives the worm 13 to drive the worm wheel 11 to rotate. At this time, the worm wheel 11 drives the rotating rod 9 together with the sealing plate 10 to be in an expanded state, thereby exposing the inner wall of the sealing plate 10 and the interior of the tundish body 1 to the outside world. The staff then cleans the inner wall of the sealing plate 10 and the interior of the tundish body 1. After cleaning, the staff turns on the reverse rotation of the motor 12 to close the sealing plate 10, that is, the interior of the tundish body 1 is isolated from the outside world, so that the staff can continue to use this device to buffer the impact force of the molten steel.
