Description

Technical Field

[0001] The utility model relates to the technical field of strip steel, in particular to a surface leveling mechanism for cold-rolled strip steel. Background Art

[0002] At present, cold-rolled strip steel is a widely used metal material, usually made of carbon steel or stainless steel. Its production process includes process steps such as cold rolling, pickling and quenching. Cold rolling refers to the process of reprocessing hot-rolled steel coils, rolling and pressing them multiple times at room temperature to make them thinner, wider, longer, and improve surface quality and mechanical properties. Cold rolling can obtain higher surface finish and better dimensional accuracy, and at the same time can also improve the hardness, strength and toughness of steel. After cold rolling, the surface flatness and dimensional accuracy of the strip steel have been greatly improved, and it is usually used in the fields of automobiles, electrical appliances, construction, aerospace, etc. In addition, cold-rolled strip steel also has excellent properties such as corrosion resistance, wear resistance, and high temperature resistance, so it is also widely used in chemical, energy and other industries. The leveling of cold-rolled strip steel refers to the flattening of its surface to eliminate or reduce surface defects such as ripples, wrinkles and unevenness, so that the strip steel meets the specified flatness and dimensional accuracy requirements.

[0003] The flattening of cold-rolled strip is usually carried out in the last process of the cold-rolled strip production line. The flattening mechanism is a device used to flatten the strip, which is mainly composed of a flattening roller and a drive system. The flattening roller is usually composed of two or more rollers. Through the action of rotation and extrusion, the strip undergoes plastic deformation when passing between the rollers, thereby eliminating surface defects and improving flatness.

[0004] The position and pressure of the leveling roller are crucial to the leveling effect. Traditional leveling mechanisms usually achieve the desired leveling effect by manually adjusting the position and gap of the leveling rollers before use. However, this method has problems such as frequent manual intervention, limited adjustment accuracy, and unstable leveling effect.

[0005] Therefore, a surface leveling mechanism for cold-rolled strip steel is needed to solve the above technical problems. Utility Model Content
