Water mist skin leveling system in cold rolling wet skin leveling production

Abstract

The invention relates to a system for performing a leveling production by means of water mist leveling. A water mist leveling system in a cold-rolling wet leveling production, which is characterized by being composed of a water mist leveling-spraying device and a water mist leveling and suction dust removal system, wherein the water mist leveling-spraying device comprises a water mist leveling-spraying beam, a telescoping mechanism and a leveling mist spraying device; the leveling mist spraying device is fixed on the water mist leveling-spraying beam; the water mist leveling-spraying beam is connected with a connection cross beam via the telescoping mechanism, and the both ends of the cross beam are fixed on the frame of a wet leveling mill respectively; the water mist leveling and suction dust removal system comprises an anti-wrapping guide plate and an inlet side air suction tube; the lower port of the anti-wrapping guide plate is a first air suction opening; the inlet side air suction tube is disposed at the inlet side of the wet leveling mill, and the lower port of the inlet side air suction tube is a second air suction opening. The system can increase the quality of strip steel surface and decrease the production energy consumption.

Description

technical field [0001] The invention belongs to the technical field of cold rolling and leveling, in particular to a system for leveling production by water mist leveling, which is applied to various cold rolling and leveling units. Background technique [0002] Traditional leveling production includes dry leveling and wet leveling. The dry skinning process will generate a lot of dust during the skinning process, which will cause surface pollution of the finished strip steel. For wet leveling, a wet leveling spray beam is arranged on the entrance side, and 8 to 12 nozzles are arranged on the spray beam, and each nozzle sprays about 108 to 168 L / h of leveling liquid, and sprays a large amount of leveling liquid onto the work roll and the strip , Flush the dust generated during the leveling process. However, after a large amount of leveling liquid is sprayed onto the strip surface, problems such as residual leveling liquid on the strip surface after leveling will be brought ...

AI Technical Summary

Problems solved by technology

Although the traditional leveling suction dust removal process can suck and discharge part of the dust and mist, but because the suction tuyere arranged above the closed cover is too high, it cannot achieve a good effect, and there are still a lot of mist and dust in the production process. Bring defects to the strip surface and affect product quality

And because the tuyere arranged on the closed cover is too high, the power requirement for the suction fan is relatively high, which consumes a lot of electric energy

[0006] Therefore, the traditional cold-rolled smoothing process has technical defects in product surface quality control
