Description

Technical Field

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

[0002] Laminar cooling is a post-rolling, controlled, in-line cooling process for hot-rolled steel plates or strips using laminar water flow. Several laminar flow manifolds are installed above the runout table of the finishing mill, forming a cooling belt. After hot rolling, the steel plates (strips) pass through the cooling belt for accelerated cooling. Existing laminar flow cooling systems primarily consist of a main pipe and multiple U-shaped tubes arranged above it. Water is supplied from the main pipe and then flows through the U-shaped tubes in a laminar flow to the hot-rolled steel plates. The laminar cooling device is prone to clogging after continuous use. If the water outlet of the U-shaped tube is clogged, the water outlet can be directly replaced. However, the U-shaped tube of the current cooling pipe is not replaceable. After long-term use, the inside of the U-shaped tube will be clogged due to the accumulation of small particles. When clogged, backwash water can only be performed at one end of the water outlet of the U-shaped tube to flush the clogged part of the U-shaped tube, and then the water outlet can be reinstalled. During backwashing, it is necessary to lay another water supply pipeline on the cooling line to connect to the outer end of the U-shaped tube, and then cut off the water supply of the main pipeline for backwashing. The operation is more troublesome, and a convenient solution to the problem of U-shaped tube clogging is needed. Utility Model Content
