Problems solved by technology

However, in the rolling and leveling process of cold-rolled sheets, various types of process lubricants are generally required to play a role in lubrication and cooling; during the process, the process lubricant drips and splashes onto the surface of the strip It is difficult to completely avoid, especially after a single rolling process is completed, the liquid remaining in the process lubricating liquid injection header is affected by the residual pressure in the pipeline, and naturally flows out from the nozzle, which will pollute the surface of the strip steel in a large area, resulting in Affect the surface quality of the finished product

Embodiment 1

[0024] like figure 1 , is a conventional jetting header, which includes a header 1, which is connected to a header liquid inlet pipe 2, and which is provided with at least one nozzle 101, which can spray the liquid in the tube to a predetermined area The nozzle 101 can be a nozzle hole of a specific shape that can play a role in spraying liquid and is directly processed on the body of the header 1, or a nozzle can be installed on the nozzle 101.

[0025] like figure 2 and image 3 , the embodiment of the present invention provides a spray header for preventing dripping, which is modified on the basis of the above-mentioned conventional spray header, including: a liquid baffle 3 is arranged on the outside of each of the nozzles 101, and each of the baffles The liquid plates 3 are all connected with a drive mechanism that drives itself to switch between the working position and the non-working position. In the non-working position, the liquid baffle plate 3 blocks the liquid...

Embodiment 2

[0038] The embodiment of the present invention relates to a cold rolling system, in which a spray header for spraying process lubricating fluid is arranged on the entrance side and / or exit side of the rolling mill, generally the spray header is arranged on both the entrance side and the exit side of the rolling mill, and Each side is provided with at least one injection header respectively above and below the strip running channel, which is easily determined by those skilled in the art according to the actual situation, and the installation position of the injection header is a conventional technology in the art, and will not be described in detail here . Preferably, each of the spraying headers adopts the spraying header for preventing dripping provided in the first embodiment above, and the specific structure of the spraying header for preventing dripping will not be repeated here.

Embodiment 3

[0040] This embodiment further describes the above-mentioned cold rolling system, which includes a rolling mill, a coiler and a cleaning device arranged between the rolling mill and the coiler, and the cleaning device is optimized as follows:

[0041] like Figure 4-Figure 6 , the embodiment of the present invention provides a floating strip surface cleaning roller, which can be used as the above-mentioned cleaning device, which includes a roll base 200 and a flexible floating roll 400, and the roll base 200 is connected with a The driving mechanism of the running channel; generally, the above-mentioned flexible floating roller 400 is arranged above the strip steel running channel to clean the upper surface of the strip steel 500, then the above-mentioned driving mechanism 300 can drive the roller seat 200 to lift, thereby driving the floating roller 400 lift. Further preferably, the bottom of the roller seat 200 is provided with a floating groove 201 with the notch facing do...

Abstract

The invention relates to an injecting header preventing liquid dripping and a cold rolling system adopting the injecting header. The injecting header comprises a flow collecting pipe which is providedwith at least one injecting port; a liquid baffle is arranged on the outer side of each injecting port; each liquid baffle is connected with a driving mechanism driving the liquid baffle to be switched between a work station and a non-work station; at the work station, each liquid baffle deviates from a liquid injecting path of the corresponding injecting port; and at the non-work station, each liquid baffle is portioned and blocked on the liquid injecting path of the corresponding injecting port. According to the injecting header, at the work station, each liquid baffle leaves the liquid injecting path of the corresponding injecting port, and each spraying port can achieve a normal injecting function; the injecting header is not different from a conventional injecting header, and normalwork requirements are guaranteed; at the non-work station, each liquid baffle can prevent liquid in the flow collecting pipe from being injected out of the corresponding spraying port or from flowingout to drip and fall on the surface of belt steel, it is avoided that the surface of the belt steel is polluted, and therefore the surface quality of the belt steel is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a spray header for preventing dripping and a cold rolling system using the spray header. Background technique [0002] Cold-rolled strip steel is required to have a high surface quality, and there must be no stains, plaques, etc. However, in the rolling and leveling process of cold-rolled sheets, various types of process lubricants are generally required to play a role in lubrication and cooling; during the process, the process lubricant drips and splashes onto the surface of the strip It is difficult to completely avoid, especially after a single rolling process is completed, the liquid remaining in the process lubricating liquid injection header is affected by the residual pressure in the pipeline, and naturally flows out from the nozzle, which will pollute the surface of the strip steel in a large area, resulting in Affect the surface quality of the finished...
