Rolled strip steel surface purging device

Abstract

The invention discloses a rolled strip steel surface purging device, and belongs to the technical field of strip steel rolling. Two groups of the rolled strip steel surface purging devices are respectively arranged at a rolling outlet and a rolling inlet of a rolling mill, and each rolled strip steel surface purging device comprises two memorial archways, a telescopic assembly, a spraying beam and a synchronous assembly, and the two memorial archways are oppositely arranged on two sides of a rolling production line; and the telescopic assemblies are arranged on the archways and connected with the spraying beams through the telescopic assemblies, and every two telescopic assemblies are connected through the corresponding synchronous assembly. The rolled strip steel surface purging device has the beneficial effects that the structure is simple, the purging effect is good, the purging angle is convenient to adjust, dirt on the surface of strip steel can be removed before the strip steel is rolled, rolling defects are prevented, after the strip steel is rolled, the emulsified liquid on the surface of the strip steel can be effectively purged away, and the rolling quality of the strip steel is improved.

Description

technical field [0001] The invention relates to the technical field of strip steel rolling, in particular to a purging device for the surface of rolled strip steel. Background technique [0002] In the steel rolling industry, strips often need to be rolled through a rolling mill. Before the strip enters the rolling mill, there may be impurities attached to the surface of the strip, and a large amount of emulsion is used for cooling and cooling during the rolling process. Lubrication, which causes a large amount of emulsion or attached sundries to remain on the surface of the strip after rolling. The sundries carried by the emulsion will further form emulsion spots, resulting in product surface defects. Function is difficult to completely solve this problem. At present, some units have added degreasing roller devices at the entrance and exit of the rolling mill.

[0002] In the steel rolling industry, strips often need to be rolled through a rolling mill. Before the strip enters the rolling mill, there may be impurities attached to the surface of the strip, and a large amount of emulsion is used for cooling and cooling during the rolling process. Lubrication, which causes a large amount of emulsion or attached sundries to remain on the surface of the strip after rolling. The sundries carried by the emulsion will further form emulsion spots, resulting in surface defects of the product. Use the purging of the rolling mill to Function is difficult to completely solve this problem. At present, some units have added degreasing roller devices at the entrance and exit of the rolling mill. Although the degreasing roller devices have certain effects, the cost is too high, the replacement is troublesome, the structure is relatively complicated, and the failure rate is high.
