Description

Technical Field

[0001] The utility model relates to the technical field of steel production equipment, in particular to a high-pressure water descaling device. Background Art

[0002] The hot rolling mill of a steel mill uses high-pressure water descaling equipment to remove the iron oxide scale on the surface of the heated steel billet to ensure the surface quality of the steel. Figure 1 As shown, it includes a descaling box 2, a descaling pipe 3, multiple descaling nozzles 4, and a water pump. The descaling box 2 is mounted on a carrier 1 of the conveyor line of the hot rolling mill, and the conveyor rollers on the carrier 1 extend into the interior of the descaling box 2. The descaling pipe 3 is annular, with its bottom end extending between two adjacent rollers in the conveyor rollers. Multiple descaling nozzles 4 are mounted on each of the four inner walls of the annular descaling pipe 3. The water pump is connected to the descaling pipe 3 via a pipe. When using high-pressure water descaling equipment to remove iron oxide from the surface of a heated billet, the heated billet enters the descaling box 2 along the conveyor rollers, and the multiple descaling nozzles 4 on the four inner walls of the annular descaling pipe 3 simultaneously spray high-pressure water onto the surface of the heated billet.

[0003] However, when the above-mentioned high-pressure water descaling equipment is used, the descaling pipe 3 is annular and the descaling nozzle 4 is fixed in position, which limits the spraying range of the descaling nozzle 4. Therefore, it is necessary to set the distance between the descaling nozzle 4 and the billet surface and the distance between adjacent descaling nozzles 4 in advance according to a certain size of the billet. Figure 1 As shown, the fan-shaped high-pressure water flow areas sprayed by two adjacent descaling nozzles 4 intersect, and the four corners of the blank are also completely covered by the water flow, so that the top surface, bottom surface and two side surfaces of the blank can be completely covered by high-pressure water.

[0004] When the cross section of the blank increases, Figure 2 As shown, at this time, there is a gap between the fan-shaped high-pressure water flow areas sprayed by the two adjacent descaling nozzles 4, and the high-pressure water sprayed by the descaling pipe 3 cannot cover the four corners of the billet. There are many descaling blind areas, and the removal rate of iron oxide scale on the surface of the billet is low. In the subsequent rolling process, the pressure of iron oxide scale will affect the rolling quality of the billet surface.

[0005] Therefore, there is currently a lack of a high-pressure water descaling device that can adapt to different sizes. Utility Model Content

[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0029] like Figure 3As shown, an embodiment of the present invention provides a high-pressure water descaling device, including a descaling box 2, a descaling pipe 3 and a water supply assembly, the descaling box 2 has a cavity inside, the cavity has a dephosphorization chamber for dephosphorization, and along the first direction, the two opposite sides of the descaling box 2 are respectively provided with openings, so that the blanks 5 transported by the conveyor roller of the conveyor line can pass through the dephosphorization chamber along the first direction; the descaling pipe 3 is arranged in the cavity, and the descaling pipe 3 includes a spray bottom pipe 301, a spray top pipe 302, a first spray side pipe 303 and a second spray side pipe 304 that can cooperate with each other to form a spray ring, wherein the spray ring is arranged on the outside of the dephosphorization chamber, the spray bottom pipe 301 and the spray top pipe 302 are arranged opposite to each other along the third direction and extend along the second direction; the first spray side pipe 303 and the second spray side pipe 304 are arranged opposite to each other along the second direction and extend along the third direction. The first direction, the second direction and the third direction are perpendicular to each other; the spray bottom pipe 301 is located between two adjacent rollers in the conveyor roller; in the spray ring, at least the spray top pipe 302, the first spray side pipe 303 and the second spray side pipe 304 are adjustable from the center of the descaling chamber; the spray top pipe 302, the first spray side pipe 303 and the second spray side pipe 304 are respectively equipped with multiple descaling nozzles 4 on the side facing the descaling chamber; the cross-section of the high-pressure water flow sprayed by the descaling nozzle 4 is fan-shaped, so that the high-pressure water areas sprayed onto the blank 5 by the multiple descaling nozzles 4 provided on the spray top pipe 302, the first spray side pipe 303 and the second spray side pipe 304 are at least partially overlapped; the water supply component is used to supply water to the spray bottom pipe 301, the spray top pipe 302, the first spray side pipe 303 and the second spray side pipe 304 respectively.

[0030] In this embodiment, the first direction is a direction perpendicular to the paper surface, the second direction is a left-right direction of the descaling box 2 , and the third direction is a height direction of the descaling box 2 .

[0031] In this embodiment, when the size of the blank 5 conveyed to the descaling chamber of the descaling box 2 by the conveyor roller is larger than that of the blank 5 of the previous batch, the worker increases the distance between the spray top pipe 302 and the center of the descaling chamber, increases the distance between the first spray side pipe 303 and the center of the descaling chamber, and increases the distance between the second spray side pipe 304 and the center of the descaling chamber, that is, the spray top pipe 302 moves up a set distance, the second spray side pipe 304 moves left a set distance, and the second spray side pipe 304 moves right a set distance, so as to achieve the following: Figure 3In the state shown, the area covered by the high-pressure water jets from the multiple descaling nozzles 4 on the top spray pipe 302 completely covers the top edge of the cross-section of the blank 5, while the areas covered by the high-pressure water jets from the multiple descaling nozzles 4 on the first spray side pipe 303 and the multiple descaling nozzles 4 on the second spray side pipe 304 completely cover the left and right sides of the cross-section of the blank 5. Furthermore, the areas covered by the high-pressure water jets from two adjacent descaling nozzles 4 on the top spray pipe 302 intersect, the areas covered by the high-pressure water jets from two adjacent descaling nozzles 4 on the first spray side pipe 303 intersect, and the areas covered by the high-pressure water jets from two adjacent descaling nozzles 4 on the second spray side pipe 304 also intersect. In this way, the high-pressure water jets from the descaling pipe 3 can completely cover the top, left, and right sides of the cross-section of the blank 5, effectively removing surface scale from the top, left, and right sides of the blank 5 and improving the descaling effect.

[0032] It can be seen that the high-pressure water descaling device can adapt to billets 5 of different specifications, and can adjust the distance between the spray top pipe 302, the first spray side pipe 303 and the second spray side pipe 304 and the descaling chamber according to the different specifications of the billets 5, so that the sprayed high-pressure water flow can completely cover the top edge, left edge and right edge of the cross section of the billet 5, greatly reducing the descaling blind area, and having a high removal rate of iron oxide scale on the surface of the billet, thereby ensuring the subsequent rolling quality of the billet.

[0033] The blank 5 enters the descaling box 2 along the conveyor rollers of the conveyor line. During the descaling process, the conveyor rollers are in continuous motion, meaning the blank 5 is in motion. Therefore, as long as the high-pressure water jet from the high-pressure water descaling device completely covers the top, left, and right sides of the blank 5's cross section, the surface oxide scale on these three sides can be effectively removed.

[0034] In this embodiment, if Figure 3 As shown, the upper surface of the spray bottom pipe 301 is evenly provided with multiple descaling nozzles 4 along its length, the lower surface of the spray top pipe 302 is evenly provided with multiple descaling nozzles 4 along its length, the first spray side pipe 303 is evenly provided with multiple descaling nozzles 4 along its length on the side facing the second spray side pipe 304, and the second spray side pipe 304 is evenly provided with multiple descaling nozzles 4 along its length on the side facing the first spray side pipe 303. The descaling nozzles 4 on the first spray side pipe 303 and the descaling nozzles 4 on the second spray side pipe 304 are in one-to-one correspondence, and the descaling nozzles 4 on the first spray side pipe 303 and the corresponding descaling nozzles 4 on the first spray side pipe 303 are at the same height.

[0035] It should be noted that the spray bottom pipe 301 is located between two adjacent rollers on the conveyor roller table, parallel to the rollers and below them. The installation position of the spray bottom pipe 301 is fixed and cannot be adjusted due to the limitations of its installation position. Furthermore, since the gap between two adjacent rollers is fixed, lowering the spray bottom pipe 301 is of little practical significance and does not increase the coverage of the high-pressure water jet from the descaling nozzles 4 on the spray bottom pipe 301 on the lower surface of the blank 5.

[0036] In order to ensure the descaling effect of the descaling nozzle 4 on the spray bottom pipe 301 as much as possible, a plurality of water outlet holes are evenly provided on the upper surface of the spray bottom pipe 301 along its length direction, and a descaling nozzle 4 is installed on each water outlet hole. The descaling nozzles 4 are evenly distributed on the entire upper surface of the spray bottom pipe 301, and the gap between two adjacent descaling nozzles 4 is shortened to 60 mm.

[0037] As a preferred embodiment, a pushing assembly is installed on the descaling box 2, and the pushing assembly includes a first pushing mechanism, a second pushing mechanism and a third pushing mechanism. The structures of the first pushing mechanism, the second pushing mechanism and the third pushing mechanism are exactly the same, wherein the first pushing mechanism is installed at the top position of the descaling box 2, and is used to drive the spray top pipe 302 to move up and down to approach or away from the spray bottom pipe 301, the second pushing mechanism is installed on the left side of the descaling box 2, and the third pushing mechanism is installed on the right side of the descaling box 2, the second pushing mechanism is used to drive the first spray side pipe 303 to move horizontally, and the third pushing mechanism is used to drive the second spray side pipe 304 to move horizontally.

[0038] Specifically, the first pushing mechanism, the second pushing mechanism and the third pushing mechanism each include a guide rod 6, a connecting rod 7 and a driving member 8. Circular holes for the guide rod 6 to pass through are respectively provided on the top, left and right sides of the descaling box 2.

[0039] The bottom end of the guide rod 6 in the first pushing mechanism passes through the circular hole on the top surface of the descaling box 2 and extends into the interior of the descaling box 2. The bottom end of the guide rod 6 is fixedly connected to the top of the spray top pipe 302. The connecting rod 7 is fixed to the top surface of the guide rod 6 and is perpendicular to the guide rod 6. The driving member 8 is fixedly mounted on the top surface of the descaling box 2, and the rod end of the driving member 8 is fixed to the connecting rod 7.

[0040] The right end of the guide rod 6 in the second pushing mechanism passes through the circular hole on the left side of the descaling box 2 and extends into the interior of the descaling box 2. The right end of the guide rod 6 is fixed to the first spray side pipe 303. The connecting rod 7 is fixed to the left end of the guide rod 6 and is perpendicular to the guide rod 6. The driving member 8 is fixedly installed on the left side of the descaling box 2, and the rod end of the driving member 8 is fixed to the connecting rod 7.

[0041] The third pushing mechanism and the second pushing mechanism are completely symmetrically arranged, so the third pushing mechanism will not be described in detail.

[0042] The driving member 8 is a pneumatic cylinder, an oil cylinder, or a linear module, a screw drive, etc. The specific driving form is not specifically limited. The driving member 8 is preferably a pneumatic cylinder.

[0043] In this embodiment, the high-pressure water descaling device includes a control cabinet, and the driving members 8 in the first pushing mechanism, the second pushing mechanism and the third pushing mechanism are all connected to the control cabinet by signal, and the control cabinet controls the operation of the driving members 8.

[0044] The high-pressure water descaling device needs to be programmed in advance according to the different specifications of the blanks 5, that is, according to the different specifications of the blanks 5, the control cabinet controls the driving parts 8 in the first pushing mechanism, the second pushing mechanism and the third pushing mechanism to respectively drive the spray top pipe 302, the first spray side pipe 303, and the second spray side pipe 304 to move the set distance in the set direction to ensure that the high-pressure water descaling device can adapt to blanks 5 of different specifications.

[0045] For example, when the next batch of blanks 5 are being transported to the descaling box 2 along the conveyor roller, the size of the blanks 5 in this batch is larger than the size of the blanks 5 being descaled. The worker inputs the size of the next batch of blanks 5 into the control cabinet and clicks the OK button. The control cabinet controls the cylinder on the first pushing mechanism to extend upward by a set length, thereby pulling the guide rod 6 and the spray top pipe 302 upward by a set distance. At the same time, the control cabinet controls the cylinders in the second pushing mechanism and the third pushing mechanism to extend by a set length respectively, thereby pushing the first spray side pipe 303 and the second spray side pipe 304 to move the set distance to the left and right respectively. To achieve the following Figure 3 In the state shown, the area covered by the high-pressure water jets from the multiple descaling nozzles 4 on the top spray pipe 302 completely covers the top edge of the cross-section of the blank 5, while the areas covered by the high-pressure water jets from the multiple descaling nozzles 4 on the first spray side pipe 303 and the multiple descaling nozzles 4 on the second spray side pipe 304 completely cover the left and right edges of the cross-section of the blank 5. Furthermore, the areas covered by the high-pressure water jets from two adjacent descaling nozzles 4 on the top spray pipe 302 intersect, the areas covered by the high-pressure water jets from two adjacent descaling nozzles 4 on the first spray side pipe 303 intersect, and the areas covered by the high-pressure water jets from two adjacent descaling nozzles 4 on the second spray side pipe 304 intersect. In this way, the high-pressure water jets from the descaling pipe 3 completely cover the top, left, and right edges of the cross-section of the blank 5, effectively removing surface scale from the top, left, and right surfaces of the blank 5 and improving the descaling effect.

[0046] It can be seen that this high-pressure water descaling device can adapt to billets 5 of different specifications, and can adjust the distance between the spray bottom pipe 301, the first spray side pipe 303 and the second spray side pipe 304 and the billet 5 according to the different specifications of the billet 5, so that the sprayed high-pressure water flow can completely cover the top edge, left edge and right edge of the cross section of the billet 5.

[0047] The blank 5 enters the descaling box 2 along the conveyor rollers of the conveyor line. During the descaling process, the conveyor rollers are in continuous motion, meaning the blank 5 is in motion. Therefore, as long as the high-pressure water jet from the high-pressure water descaling device completely covers the top, left, and right sides of the blank 5's cross section, the surface oxide scale on these three sides can be effectively removed.

[0048] As a preferred embodiment, Figure 3 The water supply assembly includes a first water supply pipeline and a second water supply pipeline. The first water supply pipeline includes a first joint pipe 9, a first hose 10, a water pipe 11, a second hose 12, and a second joint pipe 13, which are connected in sequence. The two ends of the spray top pipe 302 are sealed, and a water supply port is opened on its top side wall. A circular hole is opened on the upper surface of the descaling box 2. The bottom end of the first joint pipe 9 passes through the circular hole on the upper surface of the descaling box 2 and is connected to the water supply port on the spray top pipe 302. The top of the first joint pipe 9 is higher than the top surface of the descaling box 2. One end of the first hose 10 is connected to the top of the first joint pipe 9, and the other end is connected to the first end of the water pipe 11. Furthermore, the top and bottom ends of the first spray side pipe 303 are both sealed, and a water hole is opened on the side of its top. One end of the second hose 12 is connected to the second end of the water pipe 11, and the other end is connected to the water hole at the top of the first spray side pipe 303.

[0049] The second water supply pipeline includes a third connecting pipe 14, a third hose 15 and a bent pipe 16. The top and bottom ends of the second spray side pipe 304 are sealed. A water hole is provided on the side of the top of the second spray side pipe 304. A circular hole for inserting the third connecting pipe 14 is provided on the right side of the descaling box 2. The left end of the third connecting pipe 14 passes through the circular hole on the right side of the descaling box 2 and is connected to the water hole on the top of the second spray side pipe 304. The right end of the third connecting pipe 14 is connected to the first end of the third hose 15. The left end of the spray bottom pipe 301 is sealed, and its right end has an opening. One end of the bent pipe 16 is sealed and connected to the opening at the right end of the spray bottom pipe 301, and the other end of the bent pipe 16 is connected to the second end of the third hose 15.

[0050] The water supply assembly also includes a water pump and a water outlet pipe. The water pipe 11 and the elbow 16 are connected by a connecting pipe. A water inlet hole is opened on the side wall of the water pipe 11. One end of the water outlet pipe is connected to the water outlet of the water pump, and the other end is connected to the water inlet hole of the water pipe 11.

[0051] The water pump then pumps the water into the outlet pipe, where it flows into the water supply pipe 11. The water in the water supply pipe 11 flows from both ends of the water supply pipe 11 into the first hose 10 and the second hose 12, respectively. The water in the first hose 10 flows through the first joint pipe 9 into the top spray pipe 302, while the high-pressure water in the second hose 12 flows through the second joint pipe 13 into the first spray side pipe 303. Simultaneously, the high-pressure water in the water supply pipe 11 flows from the connecting pipe into the elbow 16. A portion of the high-pressure water that flows into the elbow 16 flows from the third hose 15 into the third joint pipe 14, ultimately flowing into the second spray side pipe 304. The remaining portion of the high-pressure water in the elbow 16 flows from the elbow 16 into the bottom spray pipe 301.

[0052] It should be noted that there are no specific limitations on the water supply assembly, as long as it can be used to supply water to the descaling pipe 3. For example, the water supply assembly can be in the form of four water pumps and four hoses, with the four water pumps supplying water to the spray bottom pipe 301, the spray top pipe 302, the first spray side pipe 303, and the second spray side pipe 304 through the four hoses.

[0053] Furthermore, it should be noted that since the position of the bottom spray pipe 301 is fixed, the elbow 16 can be either a flexible pipe or a rigid pipe. However, the positions of the top spray pipe 302, the first spray side pipe 303, and the second spray side pipe 304 need to be flexibly adjustable. Therefore, a first hose 10, a second hose 12, and a third hose 15 are provided to ensure the flexible movement of the top spray pipe 302, the first spray side pipe 303, and the second spray side pipe 304.
