Description

Technical Field

[0001] The present invention relates to the technical field of continuous casting machines, in particular to a blank discharging system for a vertical continuous casting machine. Background Art

[0002] Vertical continuous casting technology predates the current mainstream arc-type continuous casting machines. Compared to vertical continuous casting machines, the main advantages of arc-type continuous casting machines are reduced production costs and simplified operation. However, vertical continuous casting machines still offer significant advantages for very specialized steel grades. Because vertical continuous casting machines eliminate bending and straightening steps, the types of steel that can be cast are virtually unlimited. Furthermore, the completely vertical casting direction creates optimal conditions for non-metallic inclusions to float upward, ensuring exceptional internal cleanliness of the ingot.

[0003] The billet discharging method adopted by the existing vertical continuous casting machine can be referred to Chinese invention patent CN1315234A, published on October 3, 2001, which discloses "A design method and device for an inclined billet discharging system of a vertical continuous casting machine". In the patent, a swing track is connected to a swing cylinder, and the swing track can transform the billet receiving car from an upright state to an inclined state. However, there is a problem that the swing track and the straight track are not aligned, and the billet receiving car vibrates greatly when passing through the connection between the swing track and the straight track, which easily causes the billet to fall. Summary of the Invention

[0004] In order to solve the problem that the above-mentioned billet receiving car is prone to falling of billets, the present invention provides a billet discharging system for a vertical continuous casting machine. The billet discharging system of the vertical continuous casting machine uses an auxiliary track to guide the inclination angle of the billet tipping car, so that the billet discharging system runs more smoothly, is less likely to have the problem of billets falling, and is easy to maintain. Compared with the existing billet discharging system, it has a lower cost advantage, stronger practicality, and is more conducive to the promotion and development of vertical continuous casting machines.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A billet discharge system for a vertical continuous casting machine includes a billet tipping car, a tipping car track, and a tipping car winch. The tipping car track includes a main track and a secondary track. The main track is in an inclined state. The tipping car winch can pull the billet tipping car to move upward on the main track. When the billet tipping car moves downward on the main track, the secondary track can guide the billet tipping car from an inclined state to an upright state.

[0007] The main track comprises an upper inclined section and a lower inclined section which are arranged vertically. The angle between the upper inclined section and the horizontal plane is smaller than the angle between the lower inclined section and the horizontal plane.

[0008] The auxiliary track is located at the lower part of the lower inclined section, the two main tracks are located between the two auxiliary tracks, and the auxiliary tracks are in an inclined state.

[0009] The angle between the auxiliary track and the horizontal plane is smaller than the angle between the lower inclined section and the horizontal plane. The upper end of the auxiliary track corresponds to the lower inclined section, and the lower end of the auxiliary track is located above the lower inclined section.

[0010] The casting billet tipping car comprises a car body, main wheels and auxiliary wheels. The main wheels can only run on the main track, and the auxiliary wheels can only run on the auxiliary track. When the casting billet tipping car is located in the upper inclined section, the car body is in a horizontal state.

[0011] The two pairs of main wheels are arranged on the left and right sides below the vehicle body. The distance from a pair of auxiliary wheels to the right end of the vehicle body is smaller than the distance from a pair of auxiliary wheels to the left end of the vehicle body. The pair of main wheels on the right side is located between the pair of auxiliary wheels.

[0012] When the ingot tipping car moves downward from the upper part of the main track, after a pair of auxiliary wheels move to the upper end of the auxiliary track, the auxiliary wheels can run on the auxiliary track, the pair of main wheels on the right side can leave the main track, and the angle between the car body and the horizontal plane can gradually increase.

[0013] A blocking seat is provided at the lower end of the auxiliary track, which can prevent the auxiliary wheels from moving further downward. When the auxiliary wheels contact the blocking seat, the vehicle body is in an upright state, and the pair of main wheels on the left side are separated from the main track.

[0014] The vertical continuous casting machine billet discharge system also includes a dummy rod storage device, a cross-car, a pusher and a billet discharge roller, which are arranged in sequence from left to right. The pusher is located directly above the upper inclined section and can push the billet on the billet tipping car to the billet discharge roller.

[0015] The vertical continuous casting machine billet discharging system also includes a straightening machine, a vertical fire cutting machine and a billet elevator arranged in sequence from top to bottom. The billet elevator is arranged adjacent to the lower end of the lower inclined section, and the lower inclined section is arranged on the left and right of the upper inclined section.

[0016] The beneficial effects of the present invention are:

[0017] 1. It solves the problem of the existing billet discharging system that the billet is prone to falling due to the segmented swing. The system runs more smoothly and is easy to maintain. Compared with the existing billet discharging system, it has a lower cost advantage, stronger practicality, and is more conducive to the promotion and development of vertical continuous casting machines.

[0018] 2. The vertical continuous casting machine's billet discharging system has a simple structure and a rational layout. Driven by electric winches, it is easier to control and adjust, with low future maintenance costs and stable equipment operation. Furthermore, it is more convenient for equipment installation, reduces the difficulty of equipment installation, and can save a lot of costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] A vertical continuous casting machine billet discharge system includes a billet tipping car 1, a billet tipping car track 2, and a billet tipping car winch 3. The billet tipping car track 2 includes a main track 201 and a secondary track 202. The main track 201 is in an inclined state. The billet tipping car winch 3 can pull the billet tipping car 1 to move upward on the main track 201. When the billet tipping car 1 moves downward on the main track 201, the secondary track 202 can guide the billet tipping car 1 from the inclined state to the upright state. Figures 1 to 7 shown.

[0038] In this embodiment, two main rails 201 are arranged parallel to each other in front and back. The main rail 201 includes an upper inclined section 2011 and a lower inclined section 2012 arranged up and down. The angle α between the upper inclined section 2011 and the horizontal plane is smaller than the angle β between the lower inclined section 2012 and the horizontal plane.

[0039] In this embodiment, the two auxiliary rails 202 are arranged parallel to each other in the front and rear directions. The auxiliary rails 202 are located at the lower part of the lower inclined section 2012. The auxiliary rails 202 are inclined. The auxiliary rails 202 are located above the lower end of the lower inclined section 2012. In the front and rear directions, the two main rails 201 are located between the two auxiliary rails 202. The main rails 201 and the auxiliary rails 202 are parallel to each other. Figure 1 of paper.

[0040] In this embodiment, the angle γ between the auxiliary track 202 and the horizontal plane is smaller than the angle β between the lower inclined section 2012 and the horizontal plane. The upper end of the auxiliary track 202 corresponds to the lower inclined section 2012, and the lower end of the auxiliary track 202 is located above the lower inclined section 2012. Figures 1 to 7 shown.

[0041] In this embodiment, the slab tipping car 1 is capable of loading and transporting slabs and dummy bars. The slab tipping car 1 comprises a car body 101, main wheels 102, and auxiliary wheels 103. The main wheels 102 can only travel on the main track 201, and the auxiliary wheels 103 can only travel on the auxiliary track 202. When the slab tipping car 1 is located in the upper inclined section 2011, the car body 101 is horizontal, and the slab tipping car 1 is at the upper limit position. When the slab tipping car 1 is located in the lower inclined section 2012, the car body 101 is tilted.

[0042] The car body 101 is a rectangular structure. The length direction of the car body 101 is substantially the same as the extension direction of the main track 201. The car body 101 is provided with a roller assembly 104, a support base 105, a guide frame 106 and a pull rod 107. When the billet tipping car 1 and the car body 101 are in an upright state, the car body 101 is perpendicular to the horizontal plane. When the billet tipping car 1 and the car body 101 are in a horizontal state, the car body 101 is parallel to the horizontal plane. When the billet tipping car 1 and the car body 101 are in an inclined state, the car body 101 is inclined relative to the horizontal plane, such as Figures 1 to 7 shown.

[0043] The roller assembly 104 includes a plurality of rollers arranged at intervals along the length of the vehicle body 101. The roller assembly 104 includes a receiving space, and the billet or dummy rod can be placed in the receiving space on the plurality of rollers, making it easy for the billet or dummy rod to leave or enter the billet tipping vehicle 1. The support base 105 is fixed to the left side of the vehicle body 101. When the billet or dummy rod is on the roller assembly 104, the left end (or lower end) of the billet or dummy rod abuts against the support base 105, which can support the billet or dummy rod. The guide frame 106 can guide the billet or dummy rod into the receiving space on the roller assembly 104. A pull rod 107 is provided on the right side of the vehicle body 101. The pull rod 107 can rotate to adapt to the different tilt angles of the vehicle body 101 during the ascent or descent process. The pull rod 107 is connected to the tipping vehicle winch 3 via a wire rope 108.

[0044] In this embodiment, two pairs of main wheels 102 are arranged on the left and right sides below the vehicle body 101, and a pair of auxiliary wheels 103 are arranged on the right side below the vehicle body 101, that is, there are four main wheels 102 and two auxiliary wheels 103 below the vehicle body 101, and the distance from the pair of auxiliary wheels 103 to the right end of the vehicle body 101 is smaller than the distance from the pair of auxiliary wheels 103 to the left end of the vehicle body 101. Along the front-to-back direction, the pair of main wheels 102 on the right side is located between the pair of auxiliary wheels 103.

[0045] Specifically, a pair of main wheels 102 includes two main wheels 102 arranged front and rear, and a pair of auxiliary wheels 103 includes two auxiliary wheels 103 arranged front and rear. The pair of auxiliary wheels 103 and the pair of main wheels 102 on the right side can share a wheel axle, or the front auxiliary wheel 103 and the right front main wheel 102 share a wheel axle, and the rear auxiliary wheel 103 and the right rear main wheel 102 share a wheel axle.

[0046] When the ingot tipping car 1 moves downward from the upper part of the main track 201, the tipping car winch 3 releases the wire rope, and the two pairs of main wheels 102 are in contact with the main track 201. The two pairs of main wheels 102 move downward on the main track 201, and the pair of auxiliary wheels 103 will not be separated from the main track 201 and the auxiliary track 202 until the pair of auxiliary wheels 103 move to the upper end of the auxiliary track 202. After the pair of auxiliary wheels 103 move to the upper end of the auxiliary track 202, the auxiliary wheels 103 can move downward on the auxiliary track 202, and the right pair of main wheels 102 can be separated from the main track 201, and the left pair of main wheels 102 do not separate from the main track 201. The angle between the car body 101 and the horizontal plane can gradually increase. Figures 1 to 7 shown.

[0047] The lower end of the auxiliary track 202 is provided with a blocking seat 2021, which can prevent the auxiliary wheel 103 from moving further downward. When the auxiliary wheel 103 contacts the blocking seat 2021, the billet tipping car 1 is in the lower limit position, the car body 101 is in an upright state, and the left pair of main wheels 102 are separated from the main track 201. The upper part of the main track 201 is provided with a pulley block 203, and the wire rope 108 is passed around the pulley block 203.

[0048] The tipping car winch 3 is located below the upper end of the main track 201. The tipping car winch 3 contains a motor drive, a brake, a reducer, a coupling and a drum connected in sequence. The motor drive provides a power source and controls the pulling speed of the billet tipping car 1 through electric drive, making debugging simple and reliable. The brake can stop the equipment at any position on the track to protect the equipment of the entire billet discharge system. The reducer converts the high-speed output of the motor into a low-speed, high-torque output through the reducer, thereby pulling the load. The coupling connects the output shaft of the reducer and the input shaft of the drum. The drum is wound with a wire rope, and the rise and fall of the billet tipping car 1 can be controlled by the forward and reverse rotation of the drum, such as Figure 1 shown.

[0049] In this embodiment, the vertical continuous casting machine discharging system also includes a dummy rod storage device 4, a cross-car 5, a pusher 6 and a discharging roller 7 arranged in sequence from left to right. The upper part of the dummy rod storage device 4 contains a dummy rod hoisting device 401, and the pusher 6 is located directly above the upper inclined section 2011. The pusher 6 can push the billet on the billet tipping car 1 onto the billet discharging roller 7.

[0050] The structure of the cross-car 5 is similar to that of the billet discharge roller 7. The cross-car 5 includes a plurality of conveying rollers arranged to move from left to right. The pusher 6 includes a pusher hook 601, a pusher drive device 602, a sprocket 603, a chain 604 and rollers. Figure 8As shown in the figure, the pusher hook 601 can push the cast strand from the strand tipping car 1 onto the discharging roller conveyor. The pusher drive 602 can drive the pusher chain 604 and the pusher hook 601 on the chain to move left and right. The sprocket 603 converts the rotational motion of the drive unit into lateral motion to drive the pusher hook 601 to move left and right. The chain 604 moves the pusher hook 601 and mainly connects the drive mechanism and the actuator. The rollers stabilize the chain and ensure smooth and stable operation of the equipment.

[0051] In this embodiment, the vertical continuous casting machine billet discharging system further includes a straightening machine 8, a vertical flame cutting machine 9 and a billet elevator 10 which are sequentially arranged from top to bottom. The straightening machine 8 is located below the crystallizer of the vertical continuous casting machine. The billet elevator 10 is arranged adjacent to the lower end of the lower inclined section 2012. The lower inclined section 2012 is arranged on the left and right sides of the upper inclined section 2011. Figure 1 shown.

[0052] In this embodiment, the slab tipping car 1 is used to transport slabs produced by a vertical continuous casting machine from the bottom of a deep foundation pit to the zero-meter level, and to deliver dummy bars to the bottom of the deep foundation pit. This tipping car can transport both slabs and dummy bars. The tipping car track 2 transports the slab tipping car 1 from the horizontal zero-meter level to the bottom of the deep foundation pit via the track. Simultaneously, it transforms the slab tipping car 1 from a horizontal position to an upright position, ensuring that slabs produced by the vertical continuous casting machine can smoothly enter the slab tipping car 1 and be transported to the slab discharge roller table 7 at the zero-meter level.

[0053] In this embodiment, the pusher 6 can push the dummy bar or continuous casting strand from the strand tipping car 1 onto the discharge roller table 7. The discharge roller table 7 rotates, transporting the strand to the desired position. The dummy bar can be placed onto the cross-car 5 using a hoist and overhead crane, and then transported to the casting span of the steelmaking workshop via the cross-car 5. The cross-car 5 is used to transport the dummy bar to the casting span of the steelmaking workshop. The cross-car 5 is used to transport the dummy bar to the casting span of the steelmaking workshop. The dummy bar is then placed onto the dummy bar storage device 4 using a hoist and overhead crane. The dummy bar storage device 4 is used to store the dummy bar. The dummy bar hoist 401 rotates the dummy bar from a horizontal position to an upright position using a drum and a wire rope, preparing for the dummy bar to be installed on the vertical continuous casting machine. The strand elevator 10 can raise or lower the strand or dummy bar in the straightening machine and vertical flame cutting machine. The vertical flame cutting machine 9 can cut the ingot, separate the ingot from the dummy bar, or cut the ingot according to a fixed length.

[0054] The working process of the vertical continuous casting machine billet discharging system is described below.

[0055] The process of installing the dummy bar:

[0056] When the dummy bar is loaded from above, the dummy bar placed on the dummy bar storage device 4 is transported to the upper mouth of the crystallizer by a hoist installed on the beam of the factory building. The dummy bar is in an upright state and is slowly sent from the upper mouth of the crystallizer to the crystallizer from top to bottom, preparing for the production of the vertical continuous casting machine.

[0057] The vertical continuous casting machine's straightening machine 8 controls the roll gap and gradually moves the dummy rod toward the deep foundation pit of the vertical continuous casting machine. When it moves to the vertical flame cutter 9, the dummy rod needs to be separated from the billet through the vertical flame cutter 9. At this time, the billet tipping car 1 is at the lower limit position. The billet elevator 10 places the dummy rod on the billet tipping car 1 waiting in the deep foundation pit. The tipping car winch 3 reels the wire rope 108 and pulls up the billet tipping car 1 and the dummy rod placed on the tipping car track 2 until the billet tipping car 1 is at the upper limit position. At this time, the billet tipping car 1 is located below the pusher 6. The pusher hook 601 of the pusher 6 moves to the right, driving the dummy rod to move to the billet discharge roller 7. The dummy bar is then placed on the cross-car 5 by the overhead crane, and then the dummy bar is placed on the dummy bar storage device 4 by the overhead crane of the casting span. The dummy bar hoisting device 401 is controlled to pull the dummy bar from the horizontal state to the upright state, and the dummy bar is prepared to be installed again in subsequent production.

[0058] The process of lowering the dummy bar

[0059] The method of lowering the dummy bar is the reverse operation of loading the dummy bar. The dummy bar is stored in a horizontal position by controlling the overhead crane and the dummy bar hoist 401. The overhead crane then places the dummy bar on the cross-carriage 5 and transports it to the discharge span of the continuous casting machine. The overhead crane then places the dummy bar on the discharge roller table 7. The control system drives the motor of the discharge roller table 7, causing the rollers to rotate against the direction of the casting strand. At this point, the billet tipping car 1 is at its upper limit position, and the dummy bar is fed onto the horizontally positioned billet tipping car 1. The control system then controls the tipping car hoist 3 to release the wire rope 108, lowering the billet tipping car 1 with the dummy bar from the horizontal zero meter position into the deep foundation pit. The billet tipping car 1 becomes upright and is at its lower limit position. The dummy bar is then moved upward by the billet elevator 10 and transported to the straightening machine 8. The downward pressure of the straightening machine 8 is controlled to drive the dummy bar upward to the lower mouth of the mold. This completes the dummy bar lowering operation.

[0060] Vertical machine blanking process

[0061] After the vertical continuous casting machine completes the action of installing the dummy bar, the dummy bar pulls the billet through the control straightener 8. At a certain drawing speed, the billet is gradually passed through the mold, the straightener 8 and reaches the vertical flame cutting machine 9, and the billet is cut according to a certain fixed length. While the vertical flame cutting machine 9 is cutting, the billet is dragged by the bracket of the billet lifter 10. When the vertical flame cutting machine 9 finishes cutting, the billet lifter 10 controls the bracket to guide the billet into the billet tipping car 1. At this time, the billet tipping car 1 is in a vertical state and the billet tipping car 1 is at the lower limit position. The tipping car hoisting device 3 winds up the steel wire rope 108, and the billet tipping car 1 moves upward to transport the billet to the horizontal zero-meter position. At this time, the billet tipping car 1 is at the upper limit position. The pusher 6 pushes the billet from the billet tipping car 1 onto the billet discharging roller table 7 through the pusher hook 601. Thus, one billet discharging action is completed, and then the billet tipping car 1 repeats the action to continuously and quickly transport the billet.
