Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an active air field control type plate surface cleaning device for the technical problem that cannot be solved by the suction method in the leveling process, which can prevent the dust after dry leveling from falling on the finished strip steel to form spots. rust; or to avoid defects such as splashing, residue, and dripping of the leveling liquid caused by air reflection in wet leveling, and can be used for dry leveling and wet leveling, as well as liquid film leveling and surface cleaning of undegreased strip steel

Embodiment 1

[0028] see Figure 1-5 : the active air flow field control type plate surface cleaning device implemented by the present invention is located above the strip steel at the temper machine outlet, and the leveling dust on the strip upper surface and the upper work roll area is removed; the active air flow field control type plate The surface cleaning device is located at the exit of the tempering machine, and mainly includes a dust purging device 8, a roll dynamic seal 9-1, a negative pressure suction device 7 and a dust collection device 9.

[0029] The structural diagram of the dynamic seal of the roll, the negative pressure suction device and the dust collection device is as follows: Figure 1-3 shown.

[0030] The high-temperature and wear-resistant roll dynamic seal 9-1 is arranged between the dust collection device 9 and the roll, and forms a seal in dynamic contact with the roll. The roll dynamic seal 9-1 is a rubber pad.

[0031] The dust collection device 9 includes a...

Embodiment 2

[0037] see Figure 6 and 7 : The active air field control type plate surface cleaning device applied to wet leveling implemented by the present invention is located above the strip steel at the temper mill outlet, mainly including blowing device 9, collecting device 10, negative pressure suction device 8, roll dynamic Seal 10-1; during the tempering process, the purging device 9 sprays compressed air to the entrance side of the tempering machine, and seals the leveling liquid accumulated at the entrance roll gap on the entrance side of the tempering machine; the negative pressure suction device 8 And the collection device 10 realizes the airflow direction control in the gas collection space by adjusting the negative pressure intensity and the airflow direction, seals the leveling liquid on the entrance side of the tempering machine and avoids the splashing of the leveling liquid caused by the chaotic reflection direction of the purge airflow or residual defects.

Abstract

The invention relates to an active airflow field controlled plate surface cleaning device, which is positioned above band steel at the outlet of a temper mill, and is characterized by mainly comprising a purging device, a dynamic sealing piece, a negative pressure suction device and a collecting device, wherein the purging device has the airflow purging direction opposite to a roller gap; a roller dynamic sealing piece is in dynamic contact seal with a roller; a gas collecting device is arranged on the negative pressure suction device and can advance and retreat together with the negative pressure suction device; the collecting device is a combined adjustable channel which is obliquely arranged upwards; one end of the channel is aligned with the roller gap, and the other end of the channel is butted with a negative cavity open side of the negative pressure suction device; and a collecting space is always formed between the four side faces of the combined adjustable channel, the roller dynamic sealing piece, the band steel and a working roller. The active airflow field controlled plate surface cleaning device can be applied to plate surface cleaning of band steel subjected to dry temper rolling, wet temper rolling and liquid membrane temper rolling and non-degreased band steel to effectively improve the surface quality of the finished band steel.

Description

technical field [0001] The invention belongs to the technical field of cold-rolling and leveling, and in particular relates to a leveling production device for improving the surface quality of leveled products, which is applied to various cold-rolling and leveling units. Background technique [0002] During the dry skinning production process of the skin skinning unit, in order to avoid spot rust defects on the surface of the finished strip steel, the skinning dust is usually sucked away at the skin skin skin exit by suction. However, the method of negative pressure suction has high requirements on the airtightness of the suction hood. If the airtightness of the suction hood is not solved, the method of negative pressure suction cannot completely remove the flat dust. Since the strip width changes greatly during the leveling process, and at the same time, the vibration of the strip during operation is difficult to avoid, so that a good sealing effect cannot be achieved. Ther...
