Description

Technical Field

[0001] The utility model relates to the technical field of strip production lines, and particularly relates to a device for preventing cooling water from splashing at the outlets of the finishing mill stands F1-F4. Background Art

[0002] The cooling water of strip rolling mills and the cooling water between stands are scraped off by wiper plates to prevent them from being carried into the subsequent rolling processes. The existing cooling water of strip rolling mills and the cooling water between stands still have the following problems during operation:

[0003] 1. The pressure of the cooling water of strip rolling mills and the cooling water between stands is about 12 Mpa. After spraying out, it splashes everywhere. Secondly, when rolling thin gauges, the temperature requirements for the strip steel are very strict. The cooling water sprayed onto the strip steel surface causes uneven temperature, and it is difficult to control the strip shape, and it is easy to have the fault of breaking the strip steel into scrap.

[0004] 2. The cooling water of the rolling mill sprays backward with too much water volume, and the adjacent rolling mills are completely blocked by water mist. The on-site employees cannot observe the rolling condition of the strip steel between the stands in real time. When rolling abnormalities occur, they cannot be corrected and adjusted in time, and it is easy to have scrap steel accidents.

[0005] Therefore, there is an urgent need to design a device for preventing cooling water from splashing at the outlets of the finishing mill stands F1-F4 to solve the problems that the cooling water of the rolling mill in the existing strip production line splashes easily after spraying, resulting in uneven temperature on the strip steel surface and causing scrap steel accidents. Summary of the Utility Model

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a device for preventing cooling water from splashing at the outlets of the finishing mill stands F1-F4.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a device for preventing cooling water from splashing at the outlets of the finishing mill stands F1-F4, including a cross beam and a baffle curtain. A cross beam pressing plate is installed on the cross beam. The baffle curtain is fixedly connected between the cross beam and the cross beam pressing plate. Cross beam seats are installed at both ends of the cross beam. The cross beam seat includes a bottom plate and two vertical plates. The bottom plate of the cross beam seat is fixedly installed on the stand of the finishing mill.

[0008] Specifically, the cross beam adopts a "C"-shaped groove structure. There are multiple bolt through holes I on the cross beam. The outer side surface of the "C"-shaped groove structure of the cross beam is connected to the baffle curtain and the cross beam pressing plate.

[0009] Specifically, the cross beam pressing plate adopts a rectangular plate. The height of the cross beam pressing plate is the same as the height of the outer side surface of the "C"-shaped groove structure of the cross beam. There are multiple bolt through holes II on the cross beam pressing plate. The bolt through holes II on the cross beam pressing plate are in the same position and have the same size as the bolt through holes I on the cross beam.

[0010] Specifically, the baffle curtain is cut into strips by a conveyor belt. There are through holes in the upper part of the baffle curtain. Bolts pass through the through holes of the baffle curtain, bolt through holes 1, and bolt through holes 2. The bolts are threadedly connected with nuts, and the bolts and nuts cooperate to fixedly install the baffle curtain between the cross beam and the cross beam pressing plate.

[0011] Specifically, the two vertical plates of the cross beam seat are symmetrically welded to the bottom plate. Welding grooves are formed between the inner and outer sides of the vertical plates and the bottom plate. The "U" - shaped groove formed by the two vertical plates and the bottom plate opens upward and inserts the cross beam.

[0029] As Figures 7-8 shown, the crossbeam seat 2 includes a bottom plate 2.1, a bolt through-hole three 2.3, a welding groove 2.4 and two vertical plates 2.2. The bottom plate 2.1 of the crossbeam seat 2 is fixedly welded to the frame of the finishing mill group.

[0030] The two vertical plates 2.2 provided on the crossbeam seat 2 are symmetrically welded to the bottom plate 2.1. Welding grooves 2.4 are formed between the inner and outer sides of the vertical plates 2.2 and the bottom plate 2.1. The "U"-shaped groove formed by the two vertical plates 2.2 and the bottom plate 2.1 is inserted into the crossbeam 1 with the opening facing upward, and the distance between the two vertical plates 2.2 is greater than the overall thickness of the crossbeam 1.

[0031] Bolt through-holes three 2.3 are symmetrically provided on the vertical plates 2.2. Bolts 7 pass through the bolt through-holes three 2.3 on the vertical plates 2.2 and the bolt through-holes one 5 on both sides of the crossbeam 1. The bolts 7 are threadedly connected to nuts 8, and the bolts 7 and the nuts 8 cooperate to install the crossbeam seat 2 onto the crossbeam 1.

[0032] As Figures 5-6 shown, the crossbeam pressing plate 3 adopts a rectangular plate. The height of the crossbeam pressing plate 3 is the same as the height of the outer side surface of the "C"-shaped groove structure of the crossbeam. A plurality of bolt through-holes two 6 are provided on the crossbeam pressing plate 3, and the bolt through-holes two 6 on the crossbeam pressing plate 3 are in the same position and have the same size as the bolt through-holes one 5 on the crossbeam 1.

[0033] The baffle curtain 4 is cut into strips using a conveyor belt. A through hole is provided in the upper part of the baffle curtain 4. A bolt 7 passes through the through hole of the baffle curtain 4, the first bolt through hole 5, and the second bolt through hole 6. The bolt 7 is threadedly connected to a nut 8, and the bolt 7 and the nut 8 cooperate to fixedly install the baffle curtain 4 between the cross beam 1 and the cross beam pressing plate 3.

[0034] The manufacturing principle of the present utility model:

[0035] 1. Use 10# channel steel to make the cross beam 1 of the water baffle curtain, with a length of 2640 mm. Drill the first bolt through hole 5 every 100 mm on the cross beam 1.

[0036] 2. Use a 10 mm thick steel plate to cut into a long plate with a length of 2400 mm and a width of 100 mm to make the cross beam pressing plate 3. Drill a second bolt through hole 6 with a diameter of φ22 mm on the cross beam pressing plate 3, corresponding to the first bolt through hole 5 on the cross beam 1.

[0037] 3. Use a 2400*2400 mm corrosion-resistant conveyor belt with a thickness of 10 mm, open a through hole at the top, and cut the lower end into strips with a width of 100 mm to be used as the baffle curtain 4.

[0038] 4. Use a 20 mm thick steel plate to make the cross beam seat 2 as a welding base.

[0039] 5. After assembling the cross beam 1, the cross beam pressing plate 3, the cross beam seat 2 and the baffle curtain 4, weld them on the finishing mill stand.

[0040] The present utility model cuts the lower end of a 2400*2400*10 mm corrosion-resistant conveyor belt into strips with a width of 100 mm, which can effectively prevent the splashing of cooling water. And when personnel are working inside the rolling mill, it will not hinder the operation due to the overall excessive weight of the baffle curtain 4; using a waste corrosion-resistant conveyor belt to make the baffle curtain 4 is solid and durable, and will not break due to the strong impact force of the cooling water, increasing the service life; recycling waste materials can save costs and protect the environment. Using a 20 mm thick steel plate to make the cross beam seat 2 as a welding base can be directly welded on the finishing mill stand and can be used for a long time after one-time installation.
