[0036] As part of the creative concept of this application, before describing the embodiments of this application, it is necessary to analyze the reasons for the problem that the emulsion droplets contaminate the strip steel plate on the surface of the strip steel plate in the related art, and obtain the technical solutions of the embodiments of this application through reasonable analysis.

[0037] In the related art, when the strip steel plate is rolled by a rolling mill and rolled to a set thickness, laminar flow cooling is used to rapidly cool the strip steel plate. Laminar flow cooling can spray emulsion on the surface of the strip steel plate, and the emulsion absorbs the heat of the strip steel plate to cool the strip steel plate.

[0038] When the strip steel plate continues to move until its temperature drops to the set temperature, the emulsion on the surface of the strip steel plate is cleaned by blowing to avoid the formation of marks on the stored strip steel plate and reduce the surface quality of the strip steel plate.

[0039] There is steam of emulsion in the rolling mill. During normal use, there is an exhaust device to extract the steam. However, in winter when the environmental temperature is low, some emulsion in the steam state will liquefy. Especially at the position above the outlet of the rolling mill, such as forming emulsion droplets on the support frame of the rolling mill and the coiler. The liquefied emulsion droplets fall on the surface of the strip steel plate below, resulting in the defect of emulsion spots on the strip steel plate, causing product degradation and economic benefit losses.

[0040] For this reason, referring to Figure 1 , this application provides a device for preventing emulsion droplets from falling on the strip steel plate, including a scraper member 1 and a drainage groove 2; wherein, the plate member 1 is used to be arranged at the outlet of the rolling mill 8, and both ends of the plate member 1 in the width direction of the strip steel plate 6 are respectively located on both sides of the width direction of the strip steel plate 6 to prevent the emulsion droplets condensed on the device directly above the strip steel plate 6 at the outlet of the rolling mill 8 from falling on the surface of the strip steel plate 6; the plate member 1 is fixedly arranged obliquely so that the emulsion liquefied on the lower surface of the plate member 1 flows along the lower surface of the plate member 1; the drainage groove 2 is located at the lower end of the plate member 1 and is used to receive the liquid dripping from the plate member 1, thereby solving the technical problem that the emulsion droplets fall on the surface of the strip steel plate 6 at the outlet of the rolling mill 8 in the prior art.

[0041] The following elaborates in detail on the technical solutions of the embodiments of this application in conjunction with the drawings. The technical features involved in different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0042] For the convenience of description, the first direction, the second direction, and the third direction are defined, where the first direction is the direction in which the strip steel plate 6 moves under the action of the rolling mill 8, and the second direction is the width direction of the strip steel plate 6. In the drawings, the first direction is represented as the X direction, and the second direction is represented as the Y direction.

[0043] The embodiments of this application disclose a device for preventing emulsion droplets from falling on the strip steel plate. Referring toFigure 1 , including a plate member 1 and a drainage groove 2; wherein, the plate member 1 is used to be arranged at the outlet of the rolling mill 8, and both ends of the plate member 1 along the width direction of the strip steel 6 are respectively located on both sides of the strip steel 6 in the width direction, so as to prevent the emulsion droplets condensed on the device directly above the strip steel 6 at the outlet of the rolling mill 8 from falling onto the surface of the strip steel 6.

[0044] The plate member 1 is fixedly arranged obliquely, so that the emulsion liquid liquefied on the lower surface of the plate member 1 flows along the lower surface of the plate member 1.

[0045] The drainage groove 2 is located at the lower end of the plate member 1 and is used to receive the liquid dripping from the plate member 1.

[0046] Specifically, the rolling mill 8 and the coiler 9 are arranged at intervals along the first direction. After the strip steel 6 is moved out from the outlet of the rolling mill 8, it is wound into a steel coil on the coiler 9.

[0047] In this embodiment, a fixed frame is arranged between the rolling mill 8 and the coiler 9, and the fixed frame is used to support and connect the equipment on site. The fixed frame includes four vertical rods 10, and the four vertical rods 10 are arranged in an array in the horizontal plane. A cross beam or other devices are arranged above the fixed frame.

[0048] The plate member 1 is arranged at the outlet position of the rolling mill 8, directly above the strip steel 6, and the plate member 1 is installed and fixed on the vertical rod 10. In another embodiment, the plate member 1 can be fixed on other structural members according to the needs of the on-site environment.

[0049] The plate member 1 is directly above the strip steel 6, and the area directly above the area between the position where the strip steel 6 removes the emulsion on the surface by means of blowing and the position where it is wound by the coiler 9 is covered by the plate member 1, so that when there is liquefied emulsion dripping from the outlet position of the rolling mill 8 or other devices, it can be blocked by the plate member 1, avoiding the liquid emulsion from falling onto the strip steel 6.

[0050] The plate member 1 is arranged obliquely, one end of the plate member 1 along the first direction is high and the other end is low. The inclined placement of the plate member 1 can make the liquid on the plate member 1 flow along the surface of the plate member 1, flow from the high end to the low end of the plate member 1, so that the liquid on the plate member 1 converges in a set area and can fall into the drainage groove 2.

[0051] It should be noted that the emulsion steam will liquefy on the lower surface of the plate member 1. The obliquely arranged plate member 1 causes droplets to appear on the lower surface of the plate member 1. As the droplets gather, the droplets converge and flow. After the droplets flow to the lower end of the plate member 1, the droplets will drip from the plate member 1, so that the liquid on the lower surface of the plate member 1 can fall into the drainage groove 2.

[0052] The drainage groove 2 is located at the lower end of the plate member 1 and is used to receive the liquid dripping from the plate member 1.

[0053] Specifically, by providing a drainage groove 2 at the lower end of the plate member 1, the liquid droplets dripping from the lower end of the plate member 1 enter the drainage groove 2, flow within the drainage groove 2, and flow to the outside of the strip steel 6.

[0054] Refer to Figure 1 , as an alternative, the liquid received by the drainage groove 2 from the plate member 1 includes the liquid condensed on the lower surface of the plate member 1, and the emulsified liquid droplets condensed on the device directly above the strip steel 6 at the outlet of the rolling mill 8 and dripping onto the surface of the strip steel 6 and flowing along the upper surface of the plate member 1.

[0055] Exemplarily, the length of the drainage groove 2 is provided in the second direction, and both ends in the length direction of the drainage groove 2 extend to the outside of the strip steel 6 in the width direction. Further, a waste liquid bucket is provided below the end of the drainage groove 2, and the waste liquid bucket is used to receive the liquid remaining in the drainage groove 2.

[0056] Further, refer to Figure 5 , the drainage groove 2 is inclined in the second direction, one end of the drainage groove 2 in the second direction is high and the other end is low, so that the fluid in the drainage groove 2 can flow along the trajectory from the high end to the low end in the second direction.

[0057] This device avoids the downgrading of the strip steel 6 caused by the emulsified liquid dripping onto the surface of the strip steel 6. At the same time, the device is simple to install and has a low cost. The use of this device helps to ensure the surface quality of the strip steel 6.

[0058] Refer to Figure 1 , further, a flying shear 7 is provided between the rolling mill 8 and the coiler 9. After the strip steel 6 is removed from the outlet of the rolling mill 8, it passes through the flying shear 7 and then is wound by the coiler 9.

[0059] When the strip steel 6 is wound around the coiler 9 by a set length, the flying shear 7 can cut off the strip steel 6.

[0060] Refer to Figure 1 , the inclination mode of the plate member 1 is determined according to the design requirements, and the drainage groove 2 is directly below the lowest end of the plate member 1.

[0061] As an alternative, the height of the end of the plate member 1 facing the incoming material of the strip steel 6 is less than the height of the end of the plate member 1 facing the outlet of the rolling mill 8.

[0062] The drainage groove 2 is directly below the end of the plate member 1 facing the incoming material of the strip steel 6.

[0063] Specifically, the height of the end of the plate member 1 facing the incoming material of the strip steel 6 is low. When the emulsified liquid in the rolling mill 8 splashes due to impact, the plate member 1 can block the emulsified liquid, reducing or avoiding the splashed emulsified liquid from falling onto the surface of the strip steel 6, further ensuring the surface quality of the strip steel 6.

[0064] In another embodiment, the height of one end of the plate member 1 facing the incoming strip steel 6 is greater than the height of the end of the plate member 1 facing the outlet of the rolling mill 8.

[0065] As an alternative, the plate member 1 is placed obliquely, and the inclination angle of the plate member 1 is between 10° and 50°. On the one hand, the inclination angle of the plate member 1 should ensure that the liquid droplets condensed on the lower surface of the plate member 1 can flow along the plate member 1 without dripping, so the inclination angle of the plate member 1 cannot be less than 10°; on the other hand, the specifications and weight of the plate member 1 should be reduced. If the inclination angle of the plate member 1 is too large, the length and weight of the plate member 1 will increase, increasing the economic cost and making it inconvenient for installation and daily use. Therefore, the inclination angle of the plate member 1 is preferably less than 50°.

[0066] Referring to Figure 1 , as an alternative, the inclination angle of the plate member 1 is 30°.

[0067] Specifically, the inclination angle of 30° of the plate member 1 helps the liquid droplets condensed on the lower surface of the plate member 1 to flow along the plate member 1 without dripping, and the specifications of the plate member 1 are reasonable, which is convenient for installation and use.

[0068] In another embodiment, the inclination angle of the plate member 1 can be 10°, 16°, 20°, 25°, 34°, 40°, 47° or 50°

[0069] Referring to Figure 1 , as an alternative, the drainage groove 2 includes an angle steel with an upward opening.

[0070] Specifically, the drainage groove 2 is arranged in a flared structure so that the liquid dripping from the plate member 1 can fall into the drainage groove 2. Angle iron is a long strip of steel with two sides perpendicular to each other at an angle, and has good weldability, plastic deformation performance and certain mechanical strength.

[0071] After selecting an angle iron with a suitable length or cutting the angle iron to a suitable length, the angle iron is placed at one end of the plate member 1 and fixedly placed. In this embodiment, the angle iron is fixed on the column 10.

[0072] Using angle iron as the drainage groove 2, the processing of the drainage groove 2 is convenient and fast, and the cost is low.

[0073] Referring to Figure 3 , as an alternative, the plate member 1 includes a galvanized aluminum zinc steel plate 11.

[0074] Specifically, a galvanized aluminum zinc steel plate 11 with a length of 3 m, a width of 2 m and a thickness of 2 mm is adopted. The plate member 1 has excellent corrosion resistance, heat resistance and mechanical properties.

[0075] In the air at room temperature, a thin and dense zinc hydroxycarbonate film is formed on the surface of the plate member 1, which can prevent further oxidation and also form an insoluble oxide layer, playing a barrier protection function therein and having a long service life.

[0076] The ordinary hot-dip galvanized products usually have a service temperature not exceeding 230°C, and discoloration will occur at 250°C. The plate member 1 in this application can be used for a long time without discoloration in an environment of 315°C.

[0077] Referring to Figure 3 , as an alternative, the plate member 1 further includes an adsorption layer 12 disposed on the upper surface of the aluminized zinc steel plate 11, and the adsorption layer 12 can adsorb liquids and prevent liquid droplets from splashing.

[0078] Exemplarily, the adsorption layer 12 is used to adsorb liquids and prevent the liquid droplets dropping onto the upper surface of the plate member 1 from splashing due to impact, avoiding small liquid droplets detaching from the plate member 1 and falling onto the surface of the strip steel 6.

[0079] The adsorption layer 12 includes air fiber, also known as polyolefin elastomer, which is a thermoplastic elastomer of Dow Chemical with metallocene catalyst, having a narrow relative molecular mass distribution and a uniform short chain branch distribution, and the adsorption layer 12 can prevent water droplets from splashing. In another embodiment, the adsorption layer 12 may also include a polymer material such as polypropylene.

[0080] Referring to Figure 2 , as an alternative, four lifting rings 3 are fixed on the upper surface of the plate member 1, and the four lifting rings 3 are respectively located at the four end corners of the plate member 1.

[0081] It further includes four connecting rods 4 fixedly arranged, and the four connecting rods 4 are arranged in one-to-one correspondence with the four lifting rings 3, and the four connecting rods 4 are used for detachably fixing the inclined plate member 1.

[0082] Specifically, the lifting ring 3 is a lifting ring bolt welded on the upper surface of the plate member 1, and the lifting ring 3 does not penetrate through the lower surface of the plate member 1. In another embodiment, the lifting ring 3 includes a nut welded on the surface of the plate member 1 and a lifting ring bolt, and the lifting ring bolt is threadedly connected with the nut to realize the fixation of the lifting ring 3 on the upper surface of the plate member 1.

[0083] Furthermore, the lifting rings 3 are located between the regions surrounded by the sides of the plate member 1. At this time, when there are liquid droplets on the lifting rings 3, the liquid on the lifting rings 3 will flow to the upper surface of the plate member 1, avoiding the situation that the liquid droplets on the lifting rings 3 drop onto the surface of the strip steel 6.

[0084] The four connecting rods 4 are respectively and correspondingly fixed on the four vertical rods 10 of the fixed frame. The length of the connecting rod 4 is arranged in the horizontal direction, and one end of the connection is fixed on the vertical rod 10. The four connecting rods 4 include two groups of connecting rods arranged at intervals in the first direction, wherein the height of one group of connecting rods is lower than that of the other group of connections, and the heights of the two connecting rods 4 in the same group of connecting rods are the same. In this embodiment, the height of the group of connecting rods close to the rolling mill 8 is lower than the height of the group of connecting rods close to the winding machine 9.

[0085] When the plate 1 needs to be installed, only the four lifting rings 3 of the plate 1 need to be respectively and correspondingly inserted into the four connecting rods 4 after corresponding to the four connecting rods 4, and the installation of the plate 1 can be realized. When the plate 1 needs to be disassembled, only one end of the plate 1 needs to be lifted to separate two of the lifting rings 3 from two of the connecting rods 4, and then the plate 1 is moved to separate the remaining two lifting rings 3 from the remaining two connecting rods 4. The installation of the plate 1 is convenient. Only the four connecting rods 4 need to be fixed to the vertical rods 10, which is more convenient for on-site operation compared to fixing the plate 1 to the four vertical rods 10.

[0086] Refer to Figure 4 , Figure 4 The figure shows a schematic structural view of the lower surface of the plate 1. As an alternative, a plurality of thin wires 5 are provided on the lower surface of the plate 1. The plurality of thin wires 5 are arranged in sequence in the width direction of the strip steel 6. Any thin wire 5 is attached to the lower surface of the plate 1 and is arranged along the inclined direction of the plate 1.

[0087] Specifically, a plurality of thin wires 5 are densely arranged in a plurality in the second direction, and the gap between the thin wires 5 is smaller than the minimum diameter that the droplets of the emulsion can drip. Exemplarily, the thin wire 5 is an annular wire sleeved on the outside of the plate, and the plurality of thin wires 5 are arranged in sequence in the second direction.

[0088] The arrangement of the thin wires 5 can guide the droplets to flow along the thin wires 5 and reduce the occurrence of droplet dripping.

[0089] Furthermore, the plurality of thin wires 5 are formed by winding a single wire on the plate 1 to form a wire part located on the lower surface of the plate 1.

[0090] Furthermore, the thin wire 5 is a heating wire. When the heating wire is energized, the heat generated by the heating wire can heat the plate 1, and the plate 1 with a higher temperature can reduce or avoid the condensation of the emulsion on the lower surface of the plate 1.
