Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling cooling, in particular to a laminar cooling device. Background Art

[0002] Laminar cooling is a post-rolling online controlled cooling process for hot-rolled steel plates or strips using laminar water flow. Several laminar manifolds are installed above the output roller of the finishing mill to form a cooling belt. The steel plates (strips) are accelerated to cool through the cooling belt after hot rolling. The existing laminar cooling device mainly includes a main pipe and a plurality of U-shaped tubes arranged on the main pipe. The water flow is supplied from the main pipe and then flows to the hot-rolled steel plates in the form of laminar flow through the plurality of U-shaped tubes. The laminar cooling device is prone to blockage after continuous use, especially the water outlet head at the water outlet of the U-shaped tube is more prone to blockage. In actual use, the water outlet heads need to be replaced in batches regularly. When replacing, the water outlet heads on each U-shaped tube need to be removed separately. However, the hot rolling line cooling line is long, and contains a large number of U-shaped tubes and water outlet heads. Disassembling and assembling the water outlet heads one by one will consume a lot of manpower and time. Utility Model Content
