Problems solved by technology
[0002] In the production of cold-rolled stainless steel strip, especially in the production of precision strip steel (thickness ≤ 0.3 mm), due to the existence of a certain wedge shape in the raw material, during rolling, one side of the strip steel plate shape is loose and the other side is tight. On the coiling side of the rolling mill, There will be rib stripes in the middle, which will cause unevenness in the middle of the steel coil, and short scratches will be formed when the coil is uncoiled, which will affect the surface quality of the strip steel

Embodiment
[0009] Example: figure 1 , figure 2 As shown, this embodiment includes a hydraulic cylinder 1 and a guide plate 2. The hydraulic cylinder 1 is arranged on both sides of the guide plate 2. A flattening roller 3 is arranged on the guide plate 2. Both ends of the flattening roller 3 are connected to the hydraulic cylinder 1.
[0010] Guide plate 2 is made of triangular plates on both sides and rectangular plates on the triangular plates. The model of hydraulic cylinder 1 is: 63 / 36×180mm.
[0011] The base length of the triangular plate is 110mm and the height is 1300mm.
[0012] The length of the rectangular plate is 1300mm and the width is 600mm.
[0013] The length of the flattening roll is 700mm and the diameter is 80mm.

The invention belongs to an accessory means of production equipment in the metallurgical industry, and in particular relates to a flattening device of precision strip steel. The device comprises a hydraulic cylinder and a guide plate, and is characterized in that the hydraulic cylinder is arranged at the two sides of the guide plate, a flattening roll is arranged on the guide plate, and the two ends of the flattening roll are connected with the hydraulic cylinder. The flattening device can effectively flatten the rib strips in the middle of the precision strip steel, thus the influence of the rib strips on steel coils quality is eliminated, and the tests of Cold Rolling Plant of Shanxi Taigang Stainless Steel Co., Ltd prove that the device has obvious effects.
Description
Technical field: [0001] The invention belongs to auxiliary tools for production equipment in the metallurgical industry, in particular to a flattening device for precision steel strips. Background technique: [0002] In the production of cold-rolled stainless steel strip, especially in the production of precision strip steel (thickness ≤ 0.3 mm), due to the existence of a certain wedge shape in the raw material, during rolling, one side of the strip steel plate shape is loose and the other side is tight. On the coiling side of the rolling mill, There will be rib stripes in the middle, which will cause unevenness in the middle of the steel coil, and short scratches will be formed when the coil is uncoiled, which will affect the surface quality of the strip. Invention content: [0003] The object of the present invention is to provide a precision strip flattening device for flattening rib stripes. [0004] The technical solution for realizing the present invention is: compr...
