Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled flat steel production, in particular to a rough rolling mechanism for producing high-toughness and corrosion-resistant hot-rolled flat steel. Background Art

[0002] Hot-rolled flat steel production is one of the common metal processing technologies. It can process rough hot-rolled metal sheets to change their geometric shape, physical properties and surface quality. The production process of hot-rolled flat steel mainly includes raw material selection, heating, pressing machinery manufacturing, cooling and other steps. Rough rolling mechanism is usually used in the production process of hot-rolled flat steel.

[0003] For example, the announcement number CN216460844U discloses a rough rolling device for producing zigzag flat steel with high stability, including a mounting frame, bearings A are provided below the inner walls on both sides of the mounting frame, slide grooves are provided above the inner walls on both sides of the mounting frame, a rotating shaft A is installed inside the bearing A, a driving pulley is provided on one side of the outer wall of the rotating shaft A, and a two-roll pressing mechanism is installed inside the slide groove. The two-roll pressing mechanism is provided to drive the driving motor in coordination with the two-roll pressing mechanism, and the workpiece seat and the mounting frame are fixed by fastening bolts to increase the stability of the two-roll pressing mechanism, so as to realize stable rough rolling production of zigzag flat steel on the rough rolling device, and at the same time, the structure is simple. The rough rolling mechanism is simple and easy to operate, eliminating a large number of tedious steps, and effectively improving work efficiency and stability in the production process. However, there are other shortcomings when the rough rolling mechanism is in use. First, the lower pressure roller and the upper pressure roller of the rough rolling mechanism can only move up and down, and the lower pressure roller or the upper pressure roller of the rough rolling mechanism cannot be disassembled, and various types of lower pressure rollers or upper pressure rollers can be adjusted and installed, which reduces the high toughness and corrosion resistance effect of the rough rolling device. At the same time, the spacing between the lower pressure roller and the upper pressure roller is manually adjusted. Due to the weight of the upper pressure roller, it is heavier and more laborious to manually adjust the gap between the lower pressure roller and the upper pressure roller of the rough rolling mechanism. The effect of adjusting the gap between the lower pressure roller and the upper pressure roller of the rough rolling mechanism is not good. Therefore, there are still certain shortcomings when using the device. Utility Model Content
