[0037] To achieve the above object, an embodiment of the present application provides a quenching and cooling device 100. Please refer to Figures 1 to 3 , the quenching and cooling device 100 includes a first spraying unit 10 and a straightening mechanism 20 arranged in sequence along a first direction X; the first spraying unit 10 includes a first upper spraying component 11, a second upper spraying component 12 and a third upper spraying component 13 arranged in sequence along the first direction X; the second upper spraying component 12 is used to spray liquid onto the product 50 to cool the product 50; the spraying directions of the first upper spraying component 11 and the third upper spraying component 13 are respectively inclined towards one side close to the second upper spraying component 12, and the first upper spraying component 11 and the third upper spraying component 13 are used to spray liquid onto the product 50 to break the bubbles generated by the liquid sprayed by the first upper spraying component 11; the sum of the flow rates of the first upper spraying component 11 and the third upper spraying component 13 is less than the flow rate of the second upper spraying component 12.

[0038] It can be understood that the first upper spraying component 11, the second upper spraying component 12 and the third upper spraying component 13 are used to spray liquid onto the product 50 from above the product 50. Optionally, the spraying direction of the second upper spraying component 12 is perpendicular to the first direction X.

[0039] It can be understood that the first upper spraying component 11, the second upper spraying component 12 and the third upper spraying component 13 may be water curtain nozzles or a plurality of sector nozzles.

[0040] It can be understood that the sum of the volumes of the liquid sprayed by the first upper spraying component 11 and the third upper spraying component 13 per unit time is less than the volume of the liquid sprayed by the second upper spraying component 12 per unit time. Optionally, the pressure of the first upper spraying component 11 is less than the pressure of the third upper spraying component 13, the pressure of the third upper spraying component 13 is less than the pressure of the second upper spraying component 12, and the outlet width of the first upper spraying component 11 and the third upper spraying component 13 in the first direction X is greater than the outlet width of the second upper spraying component 12 in the first direction X.

[0042] Optionally, the product 50 is a wear-resistant steel plate of NM500, NM550 or NM600 grade with a thickness of 1.5 mm - 2.0 mm.

[0043] It can be understood that the straightening mechanism 20 is used to convey the product 50 along the first direction X and to straighten the product 50.

[0044] The beneficial effects of this embodiment are as follows: The first upper spraying component 11 and the third upper spraying component 13 are arranged on both sides of the second upper spraying component 12, which can break a large number of bubbles generated when the second upper spraying component 12 cools the product 50; the sum of the flow rates of the first upper spraying component 11 and the third upper spraying component 13 is less than that of the second upper spraying component 12, which can make the amount of bubbles generated by the liquids sprayed by the first upper spraying component 11 and the third upper spraying component 13 less than the amount of bubbles generated by the liquid sprayed by the second upper spraying component 12, so that the newly generated amount of bubbles is less than the amount of broken bubbles, reducing the overall amount of bubbles on the surface of the product 50 and making the cooling of the product 50 more uniform during the quenching process, solving the technical problem that a large number of bubbles cover the surface of the product 50 when using liquid quenching in the prior art. During the quenching process of the steel plate, the latent heat of phase change and phase change expansion generated by the phase change will cause the plate shape of the steel plate after quenching to be very poor, and the subsequent processing of the steel plate mainly composed of hard-phase martensite is more difficult. The straightening mechanism 20 provided in this embodiment can straighten the steel plate during the quenching process and reduce the processing difficulty.

[0045] In some embodiments, please refer to Figure 1 and Figure 2 , the first upper spraying component 11, the second upper spraying component 12 and the third upper spraying component 13 all include water curtain nozzles; the first spraying unit 10 is arranged in multiple rows along the second direction Y, and each row of the first spraying unit 10 includes a plurality of first spraying units 10 distributed along the first direction X, and the second direction Y is perpendicular to the first direction X and the spraying direction of the second upper spraying component 12; adjacent two rows of the first spraying unit 10 are arranged in a staggered manner, and the ends of adjacent two rows of the first spraying unit 10 overlap along the second direction Y.

[0046] It can be understood that the first direction X only represents the direction from the first spraying unit 10 to the straightening mechanism 20; the second direction Y represents the direction from one row of the first spraying unit 10 to another row of the first spraying unit 10 and the opposite direction.

[0047] Optionally, the first upper spraying component 11, the second upper spraying component 12, and the third upper spraying component 13 are all water curtain nozzles with the length direction being the second direction Y.

[0048] Optionally, the first direction X is the length direction of the steel plate product 50, and the second direction Y is the width direction of the steel plate product 50.

[0049] For convenience of description, the first upper spraying component 11, the second upper spraying component 12, and the third upper spraying component 13 are uniformly named spraying components, and multiple spraying components in adjacent two rows are alternately arranged along the first direction X. The ends of adjacent two rows of the first spraying units 10 overlap in the second direction Y, that is, the end of each spraying component in the second direction Y is located in the gap between two of the spraying components in the adjacent row.

[0050] The beneficial effects of this embodiment are as follows: The liquid sprayed by the water curtain nozzles is evenly distributed, which can cool the product 50 evenly; The two rows of the first spraying units 10 are arranged in a staggered manner with overlapping ends, which can make full use of the gap between two adjacent spraying components along the first direction X, and can make there be no gap between adjacent two rows of the first spraying units 10 in the second direction Y, so that the liquid can completely cover the product 50 in the second direction Y and cool the product 50 evenly.

[0051] In some embodiments, please refer to Figure 1 , the first spraying unit 10 further includes a first lower spraying component 14 arranged opposite to the second upper spraying component 12, and the first lower spraying component 14 is used for spraying liquid onto the surface of the product 50 facing away from the second upper spraying component 12 to cool the product 50.

[0054] Optionally, the first lower spraying component 14 is a water curtain nozzle with the length direction along the second direction Y.

[0055] The beneficial effects of this embodiment are as follows: The liquid sprayed by the first lower spraying component 14 can cool the product 50 from below, so that the product 50 is cooled evenly up and down; The liquid sprayed by the first lower spraying component 14 can support the product 50, balance the pressure of the second upper spraying component 12, and reduce the influence of the pressure of the first spraying unit 10 on the plate shape of the product 50.

[0056] In some embodiments, please refer to Figure 1, the spraying direction of the first upper spraying component 11 is inclined towards the side close to the straightening mechanism 20 to push the product 50 along the first direction X to the straightening mechanism 20.

[0058] The beneficial effect of this embodiment is that by pushing the product 50 with the liquid sprayed by the first upper spraying component 11, it is not necessary to use conveying rollers to convey the product 50, reducing the influence of the conveying rollers on the heat dissipation of the product 50 and enabling the product 50 to dissipate heat evenly.

[0059] In some embodiments, please refer to Figure 1 The first spraying unit 10 further includes a second lower spraying component 15. The second lower spraying component 15 and the first lower spraying component 14 are arranged in sequence along the first direction X. The spraying direction of the second lower spraying component 15 is inclined towards the side close to the straightening mechanism 20 to push the product 50 along the first direction X to the straightening mechanism 20.

[0060] It can be understood that the second lower spraying component 15 is used to spray liquid on the product 50 from below the product 50.

[0062] Optionally, the second lower spraying component 15 is a water curtain nozzle with a length direction along the second direction Y.

[0063] The beneficial effects of this embodiment are as follows: By pushing the product 50 with the liquid ejected by the second lower ejection member 15, it is possible to transport the product 50 without using a conveying roller, reducing the influence of the conveying roller on the heat dissipation of the product 50 and enabling the product 50 to dissipate heat evenly; the liquid ejected by the second lower ejection member 15 can also support the product 50 and balance the pressure of the first upper ejection member 11.

[0064] In some embodiments, please refer to Figure 1 , the first ejection unit 10 further includes a third lower ejection member 16, and the third lower ejection member 16 is disposed on a side of the first lower ejection member 14 away from the second lower ejection member 15; the angle A between the third lower ejection member 16 and the first direction X is 125° - 130°.

[0065] It can be understood that the third lower ejection member 16 is used to eject liquid onto the product 50 from below the product 50.

[0066] Optionally, the third lower ejection member 16 and the third upper ejection member 13 are oppositely arranged, and the liquid ejected by the third lower ejection member 16 generates a component force on the product 50 in the opposite direction of the first direction X.

[0068] Optionally, the third lower ejection member 16 is a water curtain nozzle with a length direction along the second direction Y.

[0069] The beneficial effects of this embodiment are as follows: The liquid ejected by setting the third lower ejection member 16 can support the product 50 and balance the pressure of the third upper ejection member 13; the angle between the third lower ejection member 16 and the first direction X is 125° - 130°, which can enable the liquid ejected by the third lower ejection member 16 to generate a smaller component force in the opposite direction of the first direction X and reduce the obstruction to the transportation of the product 50.

[0074] Optionally, the diameter of the upper pressing roller 211 is greater than the diameter of the upper straightening roller 221.

The first upper spraying member 11 and the third upper spraying member 13 can break a large number of bubbles generated when the second upper spraying member 12 cools the product 50. The newly generated bubble volume is less than the broken bubble volume, and there are fewer bubbles covering the upper surface of the product 50, making the cooling of each position of the product 50 more uniform, and solving the technical problem of a large number of bubbles covering the surface of the product 50 when using liquid quenching in the prior art.

[0099] It can be understood that the flatness detection device 500 is used to detect the product 50 after quenching and straightening. The controller is used to control the process parameters of the first spraying unit 10 and the roll gap of the straightening mechanism 20 according to the flatness of the product 50 to adjust the flatness of the subsequent product 50. The roll gap is adjusted according to the size of the product 50, so that the straightening mechanism 20 can be applicable to products 50 of different thicknesses; the roll gap is adjusted according to the flatness of the product 50 after straightening, the pressure applied to the product 50 can be adjusted, the straightening effect can be adjusted, and the qualified rate of the product 50 can be improved.
