Emulsified liquid side fluid channeling blockage device

Abstract

The invention relates to an emulsified liquid side fluid channeling blockage device, which is characterized by comprising an upper guide rail, a lead screw, a first nut, a supporting bearing pedestal, an upper right injection baffle, a coupler, a geared motor, a second nut, a lower guide rail, an upper left injection baffle, a lower left injection baffle and a lower right injection baffle, wherein the left part of the lead screw is screwed with the first nut, the right part of the lead screw is screwed with the second nut, and the middle of the lead screw is connected with the supporting bearing pedestal by a bearing; the upper end of the upper left injection baffle is fixedly connected with the first nut, the upper end of the upper right injection baffle is fixedly connected with the second nut; the upper left injection baffle and the upper right injection baffle are both arranged on the guide rail; the lower left injection baffle and the lower right injection baffle are both arranged on the lower guide rail; and the lower left injection baffle is fixedly connected with the upper left injection baffle by the connection plate, and the lower right injection baffle is fixedly connected with the upper right injection baffle by a connection plate. The device can avoid the problem of fluid channeling of super-wide injected emulsified liquid to the outlet side.

Description

technical field [0001] The invention belongs to the technical field of cold-rolling emulsification spot treatment, and in particular relates to a blocking device for side channeling of emulsion in the rolling process of a cold-rolling mill, which is applied to various cold-rolling mill units. Background technique [0002] During the rolling process of the cold rolling mill, the emulsion used for rolling lubrication flows through the work roll gap at the edge of the strip to the strip at the exit of the rolling mill, resulting in residual emulsion, such as figure 1 shown. [0003] Traditionally, a large flow of compressed air is used for side blowing close to the roll gap to block the channeling of the emulsion. Such as figure 2 shown. but using figure 2 The shown solution brings the following technical problems: [0004] 1. The purge air flow on the upper and lower surfaces of the strip interferes with each other, resulting in edge channeling that cannot be completely...

AI Technical Summary

Problems solved by technology

[0004] 1. The purge air flow on the upper and lower surfaces of the strip interferes with each other, resulting in edge channeling that cannot be completely resolved;

[0005] 2. The convection effect brought by the local high-flow compressed air will reduce the local temperature of the roll and change the thermal crown, which is not conducive to the shape control of the strip;

[0006] 3. The large flow of compressed air purging at the edge of the strip will cause a local temperature drop of the roll, resulting in uneven stress on the roll body at the edge of the strip and shortening the service life of the roll;

[0007] 4. The use of a large amount of compressed air makes the power consumption per ton of steel rise rapidly;

[0008] 5. Large flow of compressed air blowing caused serious noise on site
