Description

Technical Field

[0001] This utility model belongs to the field of metallurgical engineering technology, and relates to descaling machines, particularly a descaling machine that can be used for both continuous casting billets and steel ingots. Background Technology

[0002] On certain specialized hot-rolling production lines in some steel mills, a single line simultaneously handles both conventional continuous casting billet rolling and ingot blanking processes. According to the requirements of the rolling industry, both continuous casting billets and ingots require high-pressure water descaling to remove surface iron oxide scale. Continuous casting billets require descaling around all four sides, while ingots generally only require descaling on the bottom surface.

[0003] However, conventional continuously cast billets are relatively long, but have small cross-sectional dimensions, typically less than 500 mm in both width and thickness. Steel ingots, on the other hand, are shorter in length but have larger cross-sectional dimensions, with their width and thickness usually twice or more than that of the continuously cast billet. Therefore, the significant difference in cross-sectional dimensions between continuously cast billets and steel ingots presents a technical problem that those skilled in the art seek to solve in order to meet descaling requirements. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a descaling machine that can be used for both continuous casting billets and steel ingots. The descaling machine of this utility model is applicable to both continuous casting billets and steel ingots and can simultaneously meet the descaling requirements of both.

[0005] The technical solution of this utility model is implemented as follows: A descaling machine for continuous casting billets and steel ingots includes a housing and a conveyor roller conveyor. The conveyor roller conveyor is supported on a roller conveyor frame, and the housing is positioned above the conveyor roller conveyor. The housing has a descaling inlet and a descaling outlet arranged opposite to each other. A descaling mechanism is provided inside the housing. The descaling mechanism includes a lower descaling manifold and a U-shaped descaling manifold. The lower descaling manifold is horizontally positioned on the roller conveyor frame, and its length is adapted to the width of the steel ingot. It is connected to high-pressure water through a pipe.

[0006] The U-shaped descaling manifold is adapted to the cross-section of the continuously cast billet and consists of a horizontally arranged upper descaling manifold and vertically arranged side descaling manifolds at both ends of the upper descaling manifold. The upper ends of the side descaling manifolds are connected to the upper descaling manifold. At the same time, one end of the upper descaling manifold extends outward to the outside of the box and is connected to high-pressure water through a high-pressure hose. A lifting mechanism is provided on the box, which is connected to the U-shaped descaling manifold to facilitate the lifting and lowering of the U-shaped descaling manifold. Correspondingly, a strip-shaped hole is provided on the side wall of the box for the lifting and lowering of the upper descaling manifold.

[0007] Several descaling nozzles are installed on the lower descaling manifold, the upper descaling manifold, and the descaling manifolds on both sides for spraying high-pressure water to remove scale.

[0008] Furthermore, the lifting mechanism includes a motor, two sets of worm gears and two sets of telescopic components; the two sets of telescopic components are arranged side by side at intervals, and each telescopic component includes an inner sleeve and an outer sleeve. The outer sleeve is vertically arranged and fixed to the top cover plate of the box, and the lower end of the outer sleeve extends into the box; a support plate is horizontally provided at the top of the outer sleeve, and the two sets of worm gears are respectively arranged on the two support plates.

[0009] The motor is supported by support columns and mounted above the top cover of the housing. The motor's output shaft and the worm gears of the two sets of worm wheels are on the same straight line and connected in series. A lead screw is connected to the worm wheels of the two sets of worm wheels, and the lead screw is set vertically downward. The inner sleeve is located inside the outer sleeve and is fitted onto the lead screw, and a nut is fitted onto the lead screw. The upper end of the inner sleeve is fixedly connected to the nut, and the lower end of the inner sleeve is connected to the upper descaling manifold through a loose flange, which facilitates the motor to drive the worm wheels to rotate the nut in both directions, thereby realizing the lifting and lowering of the U-shaped descaling manifold.

[0010] Furthermore, a guiding mechanism is provided inside the box, which is located between the descaling inlet and the descaling mechanism, and is used to guide the continuously cast billet and steel ingot. The guiding mechanism includes guide plates arranged opposite to each other on both sides of the box, and two guide rods are horizontally arranged on the outer side of the guide plates, with the two guide rods spaced apart. The side wall of the box is provided with through holes corresponding to the guide rods, and guide cylinders are provided at the through holes to guide the guide rods and facilitate adjustment of the distance between the two guide plates.

[0011] Furthermore, a power mechanism is provided between the two guide rods, and the power mechanism is connected to the guide plate to drive the guide plate to move horizontally within the box.

[0012] Furthermore, the power mechanism includes a first hydraulic cylinder, which is disposed on the outside of the housing. A through hole is provided on the side wall of the housing for the piston rod of the first hydraulic cylinder to pass through. A connecting seat is provided on the outside of the guide plate, and a first connecting hole is provided on the connecting seat.

[0013] Furthermore, it also includes a locking mechanism, which is configured one-to-one with the guide tube. The locking mechanism includes a pin cylinder, which is located on the outside of the side wall of the housing and above the guide tube. The pin cylinder consists of a second hydraulic cylinder and a pin. The guide tube has a first pin hole, and the guide rod has two second pin holes. The two second pin holes are spaced apart, so that the pin of the pin cylinder can pass through the first pin hole from above and be inserted into one of the second pin holes, thereby realizing the locking of the guide plate position.

[0014] Furthermore, the box is equipped with a water collection tank, which is located between the descaling inlet and the descaling mechanism, and in the upper part of the box, for collecting descaling water from the upper surface of the continuously cast billet.

[0015] Furthermore, several water-blocking chains are provided at both the descaling inlet and the descaling outlet to prevent high-pressure water from splashing outwards during descaling.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model successfully solves the technological challenge of descaling continuous casting billets from all four sides, while steel ingots only require descaling from the bottom, by employing a combination design of a fixed lower descaling manifold and a liftable U-shaped descaling manifold. One set of equipment can flexibly adapt to two billets with vastly different dimensions, meeting the descaling requirements of both continuous casting billets and steel ingots. This eliminates the cost of configuring two independent systems, significantly saving on equipment investment and plant space, resulting in substantial economic benefits.

[0017] 2. This utility model can realize the free translation and locking of the two guide plates in the box through the guiding mechanism and locking mechanism, thereby effectively guiding the continuous casting billets and steel ingots with huge size differences, ensuring that the continuous casting billets and steel ingots can pass through the descaling machine in the center, ensuring the descaling effect, and avoiding the billet from deviating and hitting the descaling manifold.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] On certain specialized hot-rolling production lines in some steel mills, a single line simultaneously handles both conventional continuous casting billet rolling and ingot blanking processes. According to the requirements of the rolling industry, both continuous casting billets and ingots require high-pressure water descaling to remove surface iron oxide scale. Continuous casting billets require descaling around all four sides, while ingots generally only require descaling on the bottom surface.

[0028] However, conventional continuously cast billets are relatively long but have small cross-sectional dimensions, typically less than 500mm in width and thickness. Steel ingots, on the other hand, are shorter but have larger cross-sectional dimensions, usually twice or more the width and thickness of the continuously cast billet. Existing descaling machines are mostly fixed structures. While designing an annular descaling manifold based on the maximum cross-sectional dimensions of the steel ingot ensures smooth passage and completes bottom descaling, the continuously cast billet, with its much smaller cross-sectional dimensions, results in excessive distance between its sides and top surface and the descaling nozzle. This leads to insufficient high-pressure water jet pressure, hindering effective removal of iron oxide scale and severely impacting descaling efficiency. Conversely, designing a fixed annular manifold based on the continuously cast billet's cross-sectional dimensions prevents the ingot from passing through and fails to meet the bottom descaling requirements.

[0029] Based on this, the present invention provides a descaling machine for both continuous casting billets and steel ingots, see [link to relevant documentation]. Figure 1-7 , Figure 2 The arrows indicate the billet running direction. The descaling machine includes a housing 1 and a conveyor roller conveyor, which is supported on a roller conveyor frame. Multiple supports 7 are provided on the ground on both sides of the conveyor roller conveyor, and the supports 7 are fixed to the ground by anchor bolts. The housing 1 is supported on all the supports 7 by bolts, so that the housing 1 is positioned horizontally above the conveyor roller conveyor. The housing 1 has a descaling inlet and a descaling outlet arranged opposite each other. A descaling mechanism is provided inside the housing 1. The descaling mechanism includes a lower descaling manifold 6 and a U-shaped descaling manifold 5. The lower descaling manifold 6 is horizontally arranged on the roller conveyor frame and its length is adapted to the width of the steel ingot. It is connected to high-pressure water through a pipe to introduce high-pressure water. The pipe here is led out from the bottom of the lower descaling manifold 6 and a first spray valve is provided on the pipe.

[0030] The U-shaped descaling manifold 5 is adapted to the cross-section of the continuously cast billet and consists of a horizontally arranged upper descaling manifold and vertically arranged side descaling manifolds at both ends of the descaling manifold. The upper ends of the side descaling manifolds are connected to the upper descaling manifold. At the same time, one end of the upper descaling manifold extends outward to the outside of the box 1 and is connected to the water inlet seat 9 through a high-pressure hose 8. The water inlet seat 9 is connected to high-pressure water through a pipeline to introduce high-pressure water. A second jet valve is provided on the pipeline. The water inlet seat 9 is supported on the water inlet seat bracket 10, which is welded and fixed to the ground embedded plate. At the same time, a lifting mechanism is provided on the box 1. The lifting mechanism is connected to the U-shaped descaling manifold to facilitate the lifting and lowering of the U-shaped descaling manifold. Correspondingly, a strip hole for lifting and lowering the upper descaling manifold is provided on the side wall of the box 1.

[0031] Several descaling nozzles are provided on the lower descaling manifold 6, the upper descaling manifold, and the two side descaling manifolds for spraying high-pressure water to remove scale.

[0032] Thus, when descaling the bottom of the steel ingot is required, the U-shaped descaling manifold is raised to its highest position to ensure the ingot can pass smoothly through the descaling machine, and then the first injection valve is opened. When descaling the perimeter of the continuously cast billet is required, the U-shaped descaling manifold is lowered to the descaling position, and then the first and second injection valves are opened simultaneously. This can meet the descaling needs of both the continuously cast billet and the steel ingot.

[0033] In practice, the lower descaling manifold is welded to the roller conveyor frame and located between the two roller conveyors. To avoid interference with the U-shaped descaling manifold, the lower descaling manifold and the U-shaped descaling manifold are staggered. The lower descaling manifold is installed near the descaling inlet side and is separated from the U-shaped descaling manifold by one roller conveyor.

[0034] In specific implementation, the lifting mechanism 4 includes a motor 42, two sets of worm gears 43 and two sets of telescopic components; the two sets of telescopic components are arranged side by side at intervals, and the telescopic components include an inner sleeve 45 and an outer sleeve 44. The outer sleeve 44 is vertically arranged and fixed on the top cover plate of the housing 1, and the lower end of the outer sleeve 44 extends into the housing; the top of the outer sleeve 44 is provided with a horizontal support plate, and the two sets of worm gears 42 are respectively arranged on the two support plates.

[0035] The motor 42 is supported by the support column 41 and installed above the top cover plate of the housing 1. The output shaft of the motor 42 and the worms of the two sets of worm gears 43 are on the same straight line and connected in series. A lead screw 46 is connected to the worm gears of the two sets of worm gears 43, and the lead screw 46 is set vertically downward. The inner sleeve 45 is set inside the outer sleeve 44 and sleeved on the lead screw 46. A nut 47 is sleeved on the lead screw 46. The upper end of the inner sleeve 45 is fixedly connected to the nut 47, and a pressure cap 48 is sleeved on the lead screw corresponding to the top of the inner sleeve 45. The pressure cap 48 is fixed to the inner sleeve 45. The lower end of the inner sleeve 45 is connected to the upper descaling manifold through a loose flange, which facilitates the motor 42 to drive the worm gears to drive the nut to rotate in both directions, so as to realize the lifting and lowering of the U-shaped descaling manifold.

[0036] In practical applications, proximity switches 18 are respectively installed on the outer side walls of the housing at the upper and lower ends of the strip-shaped hole. The proximity switches and the motor are electrically connected to the control system. When the U-shaped descaling manifold rises to the highest position, the proximity switch at the upper end can transmit the position information to the control system, which can then control the motor to shut down. Conversely, when the U-shaped descaling manifold descends to the bottom descaling position, the proximity switch at the lower end can transmit the position information to the control system, which then shuts down the motor. Thus, the U-shaped descaling manifold can automatically stop rising and falling when it reaches the highest or descaling position.

[0037] In specific implementation, a guiding mechanism is provided inside the box body 1. The guiding mechanism is located between the descaling inlet and the descaling mechanism and is used to guide the continuously cast billet and steel ingot. The guiding mechanism includes guide plates 12 arranged opposite to each other on both sides of the box body 1. Two guide rods 14 are horizontally arranged on the outer side of the guide plates 12 and the two guide rods 14 are spaced apart. The side wall of the box body 1 is provided with through holes corresponding to the guide rods 14, and a guide cylinder 13 is provided at the through holes to guide the guide rods 14 and facilitate the adjustment of the distance between the two guide plates 12 to guide the steel ingot and continuously cast billet.

[0038] The guiding mechanism guides the steel billet, ensuring it passes through the center of the descaling mechanism along the conveyor rollers within the box, thus guaranteeing effective descaling. The guide plates here can move freely within the box, and the distance between the two guide plates can be adjusted to effectively guide the continuously cast billet and steel ingot.

[0039] In specific implementation, a power mechanism is provided between the two guide rods 14. The power mechanism is connected to the guide plate 12 to drive the guide plate 12 to move horizontally within the housing 1. The power mechanism includes a first hydraulic cylinder 17, which is located on the outside of the housing 1. A through hole is provided on the side wall of the housing 1 for the piston rod of the first hydraulic cylinder 17 to pass through, so that the piston rod of the first hydraulic cylinder can extend into the housing through the through hole. A connecting seat 15 is provided on the outside of the guide plate 12. The connecting seat 15 has a first connecting hole, and the piston rod has a second connecting hole corresponding to the first connecting hole, so that the hydraulic cylinder 17 and the guide plate 12 can be connected by passing the pin 16 through the first connecting hole and the second connecting hole in sequence.

[0040] In this way, when the first hydraulic cylinder extends or retracts, the guide plate can move freely within the housing. In practical applications, a pin cylinder 11, consisting of a second hydraulic cylinder and a pin, is located on the upper outer side wall of the housing corresponding to the guide cylinder. The guide cylinder below the pin cylinder has a first pin hole, and the guide rod has two second pin holes. These two second pin holes correspond to the positions of the guide plate when guiding the steel ingot and the continuously cast billet, respectively. When the guide plate reaches the preset position, the pin holes of the guide cylinder and the guide rod coincide, and the pin cylinder inserts the pin into the pin hole to lock the guide plate position.

[0041] In specific implementation, the housing 1 is equipped with a water collection tank 3, which is located between the descaling inlet and the descaling mechanism, and in the upper part of the housing 1, for collecting descaling water from the upper surface of the continuously cast billet. In specific applications, the water collection tank has a vortex structure.

[0042] In practice, several water-blocking chains 2 are installed at both the descaling inlet and the descaling outlet to prevent high-pressure water from splashing outwards during descaling. In this embodiment, three sets of water-blocking chains 2 are installed at the descaling inlet, and one set of water-blocking chains is installed at the descaling outlet.

[0043] Before production, the descaling machine needs to be prepared in advance according to the billet to be descaled. When the billet to be descaled is a continuously cast billet, due to the smaller size of the billet, the distance between the two guide plates should be reduced to ensure that the billet is centered and passes through the U-shaped descaling manifold to obtain the best descaling effect and to prevent the billet from deviating and hitting the descaling manifold. Two hydraulic cylinders simultaneously push the left and right guide plates inside the housing towards the center of the housing. When the displacement sensor of the hydraulic cylinder detects that the hydraulic cylinder rod has reached the preset position, the hydraulic cylinder stops moving, and the distance between the two guide plates reaches the set value. Then, the pin cylinder moves downward to insert the pin into the pin hole of the guide cylinder and guide rod, thus locking the guide plate position and preventing the distance between the guide plates from changing when the billet hits the guide plate. The position of the U-shaped descaling manifold is adjusted by the lifting mechanism until the U-shaped descaling manifold reaches the descaling position. After the proximity switch detects that the manifold is in place, the lifting mechanism stops moving. After completing the above preparations, the descaling machine enters the descaling ready state for the continuously cast billet. As the billet slowly enters the descaling machine along the rotating conveyor rollers, if its position deviates from the center of the descaling machine, the billet is corrected by the left and right guide plates to ensure it travels in the center of the machine. Then, the first jet valve corresponding to the lower descaling manifold and the second jet valve corresponding to the U-shaped descaling manifold are opened. High-pressure water descales the bottom of the billet through the nozzles of the lower descaling manifold and descales the left and right sides and the top surface of the billet through the U-shaped descaling manifold. After descaling is completed and the billet leaves the descaling machine, the jet valves are closed, thus completing the descaling process for the continuous casting billet.

[0044] When descaling steel ingots, the descaling machine should be readjusted accordingly. Due to the large size of the steel ingots, the guide plate spacing should be increased to ensure that the steel ingot passes through the descaling machine in a centered position. First, retract the pin cylinder and pull the pin back from the pin hole to release the guide plate lock. Then, retract the guide plate hydraulic cylinder to move the two guide plates to the outside of the housing, thus increasing the spacing between the two guide plates. When the hydraulic cylinder displacement sensor detects that the set position has been reached, the action stops, and the guide plate spacing meets the preset value for the steel ingot to pass through. Then, insert the pin through the pin cylinder into the corresponding pin hole on the guide cylinder and guide rod to complete the guide plate spacing adjustment. Next, start the lifting mechanism to raise the U-shaped descaling manifold to its maximum height to ensure that the steel ingot passes through the descaling machine smoothly and to prevent it from hitting the manifold. When the highest position proximity switch detects that the U-shaped descaling manifold has been raised to the correct position, the lifting mechanism automatically stops. After completing the above adjustments, the preparation work for steel ingot descaling is completed, and the descaling machine enters the steel ingot descaling ready state. When the steel ingot enters the descaling machine, the first spray valve corresponding to the lower descaling manifold is opened to spray water to descale the bottom of the ingot. At this time, the second spray valve corresponding to the U-shaped descaling manifold is not open, and no water is sprayed for descaling. After the steel ingot leaves, the spray valve is closed, and the steel ingot descaling ends. This process is repeated continuously.

[0045] In summary, the descaling machine of this utility model, by setting an adjustable spacing guide mechanism and adopting a lifting U-shaped descaling manifold, can simultaneously meet the descaling requirements of continuously cast billets and steel ingots with huge differences in shape.

[0046] Finally, it should be noted that the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations and modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
