Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled coils, in particular to a hot-rolled coil shearing device. Background Art

[0002] Hot rolled coil, referred to as hot coil, is a strip steel made from slab (mainly continuous casting slab) as raw material, which is heated by rough rolling unit and finishing rolling unit.

[0003] Hot rolled coil shearing is an important part of the hot rolled coil production process, mainly used to cut the continuous hot rolled coil according to the required length and size. When shearing the hot rolled coil with a thickness of 1mm-20mm, the hot rolled coil strip is conveyed to the workbench of the hot rolled coil shearing device. When the hot rolled coil strip moves to a certain position, the cutter of the hot rolled coil shearing device falls vertically to shear the hot rolled coil strip, which will cause the hot rolled coil to deform after shearing, resulting in a large correction amount for the hot rolled coil after shearing.
