Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a flattening machine for hot-rolled coils. Background Art

[0002] Hot rolled coils are made from slabs, which are heated and made into strip steel by roughing and finishing mills. The hot steel strip coming out of the last finishing mill is cooled to the set temperature by laminar flow and then rolled into steel coils by the coiler. After cooling, the steel coils are mainly used for straightening various specifications of plates and sheared plates. Hot rolled coils need to be leveled and cut before use.

[0003] For steel production and processing companies, steel is usually packaged in rolls for easy storage and transportation. In the process of using it to process products, the curved shape formed by roll storage must be flattened. The flattening machine is a machine that can uncoil, level and shear metal sheets. It can take into account both uncoiling and flattening of steel coils, and is therefore often used in the production and processing of sheets.

[0004] When existing leveling machines uncoil and level hot-rolled coils, most of them use multiple rollers to extrude the hot-rolled coils. However, since the hot-rolled coils need to be extruded by multiple rollers during the leveling process, the hot-rolled coils will be forced to deviate from the processing area when being extruded, thereby affecting the normal processing efficiency. Therefore, a leveling machine for hot-rolled coils is proposed to solve the above problem. Utility Model Content
