Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a hot rolling device for steel processing. Background Art

[0002] Hot rolling is a common process in steel processing, used to improve the mechanical properties, dimensional accuracy, and surface quality of steel. Hot rolling equipment changes the shape and size of a steel billet by passing it through one or more pairs of rotating rolls, after heating it to above the recrystallization temperature.

[0003] However, during the production and processing of steel, especially before hot rolling, a layer of iron oxide scale (commonly known as phosphorus scale or oxide scale) is usually formed on the surface of the steel. This layer of oxide scale is mainly generated by the reaction of steel with oxygen in the air during heating. If these oxide scales are not removed in time, they may affect the surface quality, mechanical properties and quality of subsequent processing of the steel.

[0004] In order to solve the above problems, we propose a hot rolling device for steel processing, which can dephosphorize the steel before hot rolling to improve the comprehensive performance of the steel. Utility Model Content

[0021] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0022] Example 1: A hot rolling device for steel processing, such as Figure 1 and Figure 2 As shown, it includes a heating box 1, hot rolling rollers 2, gears 3, reduction motors 4, flat belts 5, feed plates 6, water tanks 7, water pipes 8 and high-pressure nozzles 9. The heating box 1 is rotatably connected to two groups of left and right hot rolling rollers 2. The hot rolling rollers 2 are in a group of two, and the two hot rolling rollers 2 in each group are symmetrically arranged up and down. The front of the hot rolling rollers 2 is fixedly connected with gears 3, and the two adjacent gears 3 are meshed with each other. The lower left part of the heating box 1 is fixedly connected with a reduction motor 4, and the output shaft of the reduction motor 4 is fixedly connected to the hot rolling roller 2 at the lower left. The front of the two hot rolling rollers 2 on the lower side is connected with a flat belt 5 through a pulley. The left part of the heating box 1 is fixedly connected with a feed plate 6, and the feed plate 6 is a hollow structure for easy drainage. The upper left part of the heating box 1 is fixedly connected with a water tank 7, and a cover is provided on the upper front side of the water tank 7. The front and rear sides of the water tank 7 are connected with water pipes 8. The left part of the heating box 1 is fixedly connected with high-pressure nozzles 9 that are symmetrical up and down, and the high-pressure nozzles 9 are connected to the tail end of the water pipe 8.

[0023] When using the device, the staff puts the steel into the heating box 1 from the left side of the device, supports the steel through the feed plate 6, and when the steel moves to the right, the water in the water tank 7 is introduced into the high-pressure nozzle 9 through the water pipe 8. The water is sprayed out through the high-pressure nozzles 9 on the upper and lower sides to flush the upper and lower sides of the steel, thereby removing the oxide scale on the surface of the steel. The steel after dephosphorization continues to move to the right to the hot rolling roller 2, and the hot rolling roller 2 is driven to rotate by the reduction motor 4, flat belt 5 and gear 3. The rotation of the hot rolling roller 2 can hot-roll the steel, and the hot-rolled steel is sent out from the right side of the device. In this way, the steel can be dephosphorized before hot rolling to avoid the oxide scale on the surface of the steel affecting the quality of the steel and improve the comprehensive performance of the steel.

[0024] Example 2: Based on Example 1, Figure 1 、 Figure 3 and Figure 4 As shown, it also includes a cleaning component for scraping residual water and oxides on the surface of the steel, and the cleaning component includes a guide rod 10, a dewatering plate 11 and a threaded rod 12.

A rotating handle is fixedly connected to the upper part of the threaded rod 12, and the rear end of the dewatering plate 11 is threadedly connected to the threaded rod 12.

[0025] When using this device, the staff can rotate the threaded rod 12 according to the thickness of the steel. The rotation of the threaded rod 12 drives the dewatering plate 11 to adjust the height up and down. When the dewatering plate 11 is adjusted to the appropriate height, the staff stops rotating the threaded rod 12. When the steel after dephosphorization moves to the right, the dewatering plate 11 can contact the surface of the steel, and then scrape off the residual water on the surface of the steel to avoid affecting the hot rolling effect.

[0026] like Figure 1 and Figure 5 As shown, it also includes a recovery component for recovering water, and the recovery component includes a collecting box 13, a filter joint 131, a connecting pipe 14, a recovery pump 15, a recovery pipe 16 and a baffle 17.
