It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0026] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

The term "two or more" includes two or more cases.

[0027] The following is in conjunction with the appendix Figure 1-3 Transition plate 10 is described in some embodiments of this application.

[0028] The transition plate 10 according to this embodiment includes: a transition plate body 1 and a cooling pipe 2. The transition plate body 1 is disposed at the exit of the endless production line mill and is used to realize the transition of the product. In the thickness direction of the transition plate body 1, such as... Figure 1 and Figure 2 As shown, the transition plate body 1 has a first side 11 and a second side 12 disposed opposite to each other.

[0029] The first side 11 is used for the transition steel plate, and the second side 12 is provided with a cooling pipe 2, which is attached to the second side 12; so that the cooling pipe 2 can better exchange heat with the transition plate body 1. Qi Zong, the cooling pipe 2 can be filled with coolant, water or other heat-exchangeable liquids, which are not limited here.

[0030] Among them, such as Figure 2As shown, the cooling pipe 2 includes a plurality of first pipes 21 and a plurality of second pipes 22. The extending directions of the first pipes 21 and the second pipes 22 intersect, and the first pipes 21 and the second pipes 22 are bent and connected end to end.

[0031] The transition plate 10 according to this embodiment can achieve the transition of products at the outlet position of the headless production line rolling mill. At the same time, coolant can be passed through the cooling pipe 2 to cool down and dissipate heat from the transition plate 10, avoiding safety accidents such as scalding of employees, and reducing the risk of deformation caused by excessive temperature, thereby reducing the possibility of production accidents such as steel piling and fracture at the transition position.

[0032] In some embodiments, the cooling flow channel has a cooling inlet and a cooling outlet, and the caliber of the cooling inlet is smaller than that of the cooling outlet. In this way, it is convenient for the cooling water to circulate and flow, keeping the water path unobstructed.

[0033] In some embodiments, a turbine power generation device is provided at the cooling outlet, and the turbine power generation device is adapted to be connected to a storage battery. In this way, the cooling water at the outlet can be used to supply energy to the turbine power generation device for power generation, thereby realizing energy recovery and utilization.

[0034] In some embodiments, an optical fiber temperature sensor 5 is provided on the second side 12. The optical fiber temperature sensor 5 is used to detect the current temperature of the transition plate 10, and the optical fiber temperature sensor 5 can be electrically connected to an electronic device (such as a mobile phone or a computer), so that the user can obtain the current temperature of the transition plate 10 in real time, and thus the flow rate of the cooling pipe 2 can be controlled according to the current temperature.

[0035] In some embodiments, as Figure 3 shown, an electric control valve and / or a water pump 31 are provided at the cooling inlet. In this way, it is convenient to control the flow rate of the cooling water through the electric control valve, and / or the water pump 31 can provide energy for the flow of the cooling water to ensure the flow of the cooling water.

[0036] In some embodiments, as Figure 2 shown, the cooling pipe 2 can be a plurality of "U-shaped" pipelines connected in sequence. In this way, when the cooling water flows through the cooling pipe 2, compared with a straight pipeline, the heat exchange area of the cooling pipe 2 of the present application is larger, that is, it can cover a wider area, avoid local heat concentration, and achieve uniform heat dissipation.

[0037] Understandably, the symmetrical "U"-shaped pipe design can balance the distribution of thermal stress during the cooling process, reducing warping or deformation of the transition plate 10 caused by uneven cooling on one side. In particular, the geometric structure formed by the curved path can disperse external loads (such as the pressure of high-temperature steel plates), enhancing the overall compressive strength of the transition plate 10. Moreover, in the high-temperature environment of 900℃~1000℃ in the continuous casting and rolling production line, the large flow rate and efficient heat dissipation capacity of the "U"-shaped water tank can quickly remove the heat from the surface of the transition plate 10, preventing material softening or failure. At the same time, the reasonable design of the water flow path (combined with the variable diameter structure of narrow inlet and wide outlet) can maintain the water flow rate, prevent impurities from accumulating and clogging the channel, and extend the service life.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, the transition plate body 1 has a mounting groove 13, and the cooling pipe 2 is located in the mounting groove 13. This facilitates the assembly of the cooling pipe 2 and the transition plate body 1, thereby enhancing the connection stability between the cooling pipe 2 and the transition plate body 1, and reducing the impact on the size of the transition plate body 1, thus facilitating the miniaturization design of the transition plate 10.

[0039] In some embodiments, such as Figure 3 As shown, the transition plate 10 further includes a cover plate 4, which is located on the side of at least a portion of the cooling pipe 2 away from the transition plate body 1, and is connected to the transition plate body 1 to restrict the separation of the cooling pipe 2 from the transition plate body 1. This facilitates the use of the cover plate 4 to restrict the separation of the cooling pipe 2 from the transition plate body 1, thereby enhancing the connection stability between the cooling pipe 2 and the transition plate body 1.

[0040] In some embodiments, the inner wall of the mounting groove 13 is provided with a superhydrophobic nano-coating. This reduces scale buildup, and a pulse backwashing port can be provided for periodic removal of impurities.

[0041] In some embodiments, such as Figure 1 As shown, the first side 11 is provided with a sensor mounting hole 14, which is offset from the cooling pipe 2 in the thickness direction of the transition plate body 1.

[0042] This facilitates the installation of sensors on the first side 11. The sensors can be laser sensing devices used to detect the thickness of the steel at the product exit. The laser sensing devices can be linked with other equipment (such as the main machine of the rolling mill) to automatically control the thickness of the strip produced by the rolling mill. Later, the production parameters of the product can be analyzed through data collection.

[0043] In some embodiments, the transition plate body 1 includes a steel plate layer and a wear-resistant coating, wherein the wear-resistant coating is applied to the surface of the steel plate layer.

[0044] For example, the steel plate layer can be 25CrMo alloy steel, and the wear-resistant coating can be a high-hardness wear-resistant coating (such as tungsten carbide coating) to achieve dual protection of "wear resistance and high temperature resistance". In particular, the steel plate layer and the wear-resistant coating are seamlessly combined through the spraying process, which increases the overall compressive strength by 40% and reduces the high temperature creep rate by 50%.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, at least two cooling pipes 2 are provided, and the at least two cooling pipes 2 are spaced apart in the width direction of the transition plate 10.

[0046] This facilitates increasing the heat exchange area between the cooling pipe 2 and the transition plate body 1, which means it can cover a wider area of ​​the second side 12, avoid local heat concentration, and achieve uniform heat dissipation.
