Technical Field

[0001] This utility model relates to the field of rolling mill technology, and in particular to a high-speed finishing rolling mill. Background Technology

[0002] A rolling mill is a piece of equipment used to perform the metal rolling process. It generally refers to the equipment that completes the entire process of rolled material production. Rolling mills can be classified according to the number of rolls, such as two-roll, four-roll, six-roll, eight-roll, twelve-roll, and eighteen-roll mills. A rolling mill mainly consists of rolls, a frame, a roll gap adjustment device, a transmission device, a lubrication system, a control system, and a roll removal device. Finishing mills also include a precision rolling unit.

[0003] Existing finishing mills produce metal sheets at high temperatures after rolling. These sheets are relatively soft, and directly winding them can easily damage them.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] Example 1: A high-speed finishing mill, see [link to example]. Figures 1 to 4 The invention includes a rolling mill body 1 and a cooling structure 2. The cooling structure 2 is located at the discharge end of the rolling mill body 1. The cooling structure 2 includes a support plate 201, a water channel A202, and a water channel B203. The support plate 201 is fixed to the frame at the discharge end of the rolling mill body 1. The water channel A202 is fixed to the support plate 201. The water channel B203 is arranged above the water channel A202 via an adjusting component 205. Both ends of the water channels A202 and B203 are fixedly equipped with caps 204. The water channels A202 and B203 are connected via a connecting component 206. This invention, by setting up the support plate 201, water channel A202, and water channel B203, has the advantage of heat exchange and cooling of the rolled metal sheet, reducing the temperature of the rolled metal sheet, and solving the problem that directly winding high-temperature metal sheets can easily cause damage to the metal sheet.

[0031] Specifically, water channels A202 and B203 are both designed in an arc shape on opposite sides. The arc-shaped water channels A202 and B203 form a passage cavity with large openings at both ends, which facilitates the entry of metal plates and increases the heat exchange area, thereby enhancing the heat exchange effect.

[0032] Furthermore, the adjusting component 205 includes a connecting block 2051, a threaded rod 2052, and a rotating handle 2053; the connecting block 2051 is fixed to one end of the water channel B203; the threaded rod 2052 is threaded through the connecting block 2051; wherein, the bottom end of the threaded rod 2052 is rotatably mounted on the support plate 201 via a rotating shaft; the rotating handle 2053 is fixed to the top end of the threaded rod 2052. This invention, by setting the connecting block 2051, the threaded rod 2052, and the rotating handle 2053, has the advantage of being able to adjust the distance between water channels A202 and B203 according to the thickness of the rolled metal sheet, maintaining an optimal heat exchange distance.

[0033] Furthermore, the connecting component 206 includes a sleeve 2061 and a connecting pipe 2062; one end of the sleeve 2061 is fixed at the connecting hole of waterway B203; one end of the connecting pipe 2062 is fixed at the connecting hole of waterway A202; wherein, the other end of the connecting pipe 2062 is inserted into the circular hole A2064 opened at the other end of the sleeve 2061. This utility model, by setting the sleeve 2061 and the connecting pipe 2062, has the advantage of connecting waterways A202 and B203 while adapting to the adjustment of the distance between waterways A202 and B203, thus always maintaining the connection between waterways A202 and B203.

[0034] It is worth noting that a piston ring 2063 is fitted onto the other end of the connecting pipe 2062. The piston ring 2063 is movably disposed within a circular hole B2065 opened at one end of the sleeve 2061. The circular hole B2065 communicates with a circular hole A2064, and the diameter of the circular hole B2065 is larger than the diameter of the circular hole A2064. This invention, by incorporating the piston ring 2063, maintains a tight seal at the connection between the connecting pipe 2062 and the sleeve 2061, thus preventing water leakage.

[0035] Working principle: Using the device of this invention, the connector at the inlet end of water channel A202 is connected to the external cooling water input pipeline, and the connector at the outlet end of water channel B203 is connected to the external cooling water return pipeline. Depending on the thickness of the rolled metal sheet, rotating the handle 2053 causes the threaded rod 2052 to rotate, and the connecting block 2051 moves longitudinally relative to the threaded rod 2052, causing water channel B203 to move together. The total length of the connecting pipe 2062 and the sleeve 2061 changes accordingly, and the piston ring 2063 moves within the circular hole B2065 until the distance between water channels A202 and B203 is suitable for the corresponding thickness of the metal sheet. After water channel A202 is filled, cooling water flows through the connecting pipe 2062 and the sleeve 2061 into water channel B203, and then exits after water channel B203 is full. The metal sheet passing between water channels A202 and B203 is heated by the flowing cooling water, thereby reducing the temperature of the metal sheet.

[0036] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
