Description

Technical Field

[0001] The utility model relates to a strip steel cold rolling device, belonging to the technical field of cold rolling pickling equipment. Background Art

[0002] Cold rolling generally rolls thin plates or ultra-thin plates, and has very high requirements on the surface quality of the steel strip. The raw materials are generally hot-rolled coils imported from other hot rolling mills. During transportation, especially after long storage time, oxidation is relatively serious. Pickling can wash away defects such as iron oxide scale and rust spots on the surface of the raw materials to make the surface smooth and clean.

[0003] Publication No.: CN218059227U, mentions a narrow strip cold rolling pickling device, the cold rolling pickling device includes a pickling component and an auxiliary component, the auxiliary component includes a fixed plate, a telescopic part and a positioning part, the fixed plate is fixedly connected to the pickling component, one end of the telescopic part is fixedly connected to the fixed plate, and the other end of the telescopic part is fixedly connected to the positioning part. To a certain extent, the existing device for reducing the acid consumption of cold rolling pickling is improved, and the pickling effect is reduced due to the fact that the rolled plate and the pickling liquid cannot be fully contacted. However, after the pickling of the strip in the device is completed, the pickling liquid remaining on its surface cannot be wiped off, which affects the subsequent use. Now a strip cold rolling device is urgently needed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a strip steel cold rolling device, including a pickling tank 2, an electric telescopic rod 6 and a connecting frame 7. A first strip steel guide roller 3 is arranged at the upper left end inside the pickling tank 2, and a second strip steel guide roller 5 is arranged at the upper right end inside the pickling tank 2. The electric telescopic rod 6 is longitudinally installed at the rear end of the pickling tank 2, and the connecting frame 7 is suspended in the pickling tank 2. A first strip steel limiting roller 8 and a second strip steel limiting roller 9 are horizontally installed at the lower end of the connecting frame 7. An electric push rod 10 is obliquely fixed to the front and rear sides of the right end of the connecting frame 7, and a first fixed shaft 11 is installed between the movable ends of the two electric push rods 10. A first corrosion-resistant scraper 12 is obliquely fixed to the right end of the first fixed shaft 11, a second fixed shaft 13 is horizontally installed at the right end of the pickling tank 2, and a second corrosion-resistant scraper 14 is obliquely fixed to the left end of the second fixed shaft 13. This design solves the problem that after the pickling of the strip steel in the original device is completed, the pickling liquid remaining on its surface cannot be wiped off, thereby affecting subsequent use.

[0019] As the first embodiment of the utility model: the pickling tank 2 is arranged outside the support seat 1, and the pickling tank 2 can be supported by the added support seat 1. A drainage pipe 4 is provided through the lower side of the rear end of the pickling tank 2, and the added drainage pipe 4 facilitates the discharge of the pickling liquid after use in the pickling tank 2. The movable end of the electric telescopic rod 6 is connected to the connecting frame 7, and the connecting frame 7 can be adjusted to rise and fall by the added electric telescopic rod 6, which can drive the first strip steel limiting roller 8 and the second strip steel limiting roller 9 to adjust their height accordingly, thereby changing the pickling depth of the strip steel.

[0020] The second corrosion-resistant scraper 14 and the first corrosion-resistant scraper 12 are arranged in a staggered manner, and the residual pickling liquid on the surface of the strip can be scraped off by the added second corrosion-resistant scraper 14 and the first corrosion-resistant scraper 12. The inner side of the pickling tank 2 is engraved with a pickling liquid scale, and the added pickling liquid scale can remind outsiders to add the pickling liquid depth in the pickling tank 2.

[0021] As a second embodiment of the utility model: first, place the steel strip on the upper end of the first steel strip guide roller 3, then pass the steel strip through the first steel strip limiting roller 8 and the second steel strip limiting roller 9, then pass it through the gap between the first corrosion-resistant scraper 12 and the second corrosion-resistant scraper 14, and then connect it to the external steel strip winding equipment through the second steel strip guide roller 5, then start the electric telescopic rod 6, the movable end of the electric telescopic rod 6 can drive the connecting frame 7 to move downward, so that the first steel strip limiting roller 8 and the second steel strip limiting roller 9 move downward accordingly, and due to the limitation of the first steel strip limiting roller 8 and the second steel strip limiting roller 9, the steel strip at this location can be driven to move downward, and Immerse it in the pickling tank 2 and contact it with the pickling liquid, and then start the two electric push rods 10. The movable ends of the two electric push rods 10 can drive the first fixed shaft 11 and the first corrosion-resistant scraper 12 to move to the lower right until the first corrosion-resistant scraper 12 is in contact with one side of the upper end surface of the strip, and the second corrosion-resistant scraper 14 is in contact with one side of the lower end surface of the strip. The external strip winding equipment winds the strip. During this process, the strip between the first strip limiting roller 8 and the second strip limiting roller 9 will be pickled in the pickling tank 2, and then the pickled strip will pass through the first corrosion-resistant scraper 12 and the second corrosion-resistant scraper 14, and the pickling liquid remaining on its two side surfaces will be scraped off.
