Abstract

The invention discloses an up-spray laminar flow cooling device which comprises multiple up-spray device groups. Each up-spray device group comprises 4-6 up-spray devices; each up-spray device comprises a header and two plungers, wherein multiple spray pipes are uniformly distributed on the header; two plunger holes are arranged above the two ends of the header; and the two plungers are arranged in the plunger holes respectively. Each up-spray device group also comprises two shoulder pole beams, two hydraulic cylinders and multiple pairs of plunger connection mechanisms, wherein the two shoulder pole beams are vertically arranged at the two sides of the header respectively; the two hydraulic cylinders are arranged between adjacent two headers in the middle; the hydraulic rods of the hydraulic cylinders are arranged in parallel with the headers; ear rings of the two hydraulic cylinders are fixedly connected with the two shoulder pole beams respectively through the two hydraulic cylinder connection mechanisms; and the multiple pairs of plunger connection mechanisms are used for connecting the plungers and the shoulder pole beams, and comprise multiple pairs of free connection mechanisms.

Description

technical field

[0001] The invention relates to a laminar flow cooling device, in particular to an upper spray laminar flow cooling device with adjustable width on one side in the hot rolling cooling process. Background technique

[0002] The laminar flow cooling device is used in the hot rolling and continuous rolling mill production lines of iron and steel enterprises. Its main function is to quickly cool the strip steel exported from finish rolling according to the target temperature set by coiling to ensure the product performance of the strip steel.

[0003] Taking Baosteel 2050 hot rolling plant as an example, its laminar flow cooling device has a total of 76 sets of cooling headers (corresponding to the upper and lower sets). Among them, the first 68 groups are the main cooling section, and the last 8 groups are the refined cooling section. It is generally divided into several cooling zones, and each cooling zone has its own main cooling section and the cooling secti...
