Description

Technical Field

[0001] The invention relates to the technical field of strip steel rolling production equipment, in particular to a strip steel lower surface blowing device which moves with an anti-vibration roller. Background Art

[0002] During the skin-pass rolling process for plate and strip, the skin-pass mill is typically equipped with an inlet wet-skinning spray beam, an outlet compressed air purge beam, anti-wrinkle rollers, anti-chatter rollers, a line roller, and a tension gauge roller. During rolling, residual skin-pass fluid on the strip surface can cause quality defects such as streaking. For offline skin-pass mills seeking high yields, a common solution is to use compressed air to purge the strip surface. The effectiveness of this purge is significantly affected by the nozzle type, flow rate, pressure, and the distance and angle between the nozzle and the strip. The optimal spray distance for the nozzle often falls within a narrow range depending on the nozzle model. Furthermore, the closer the anti-wrinkle rollers, anti-chatter rollers, and purge beams are to the rolls, the better the performance. Therefore, for skin-pass mills requiring a compact layout, the space for the purge beams is limited. Furthermore, the vertical movement of the anti-wrinkle and anti-chatter rollers, depending on process requirements, further increases the uncertainty of the purge distance and angle. Conventional purge beams are typically fixed, which undoubtedly limits the effectiveness of the skin-passing fluid. Specifically, the existing technology usually adopts a method of fixing the blowing collection pipe on the inner side of the leveling machine arch. When the anti-vibration roller moves up and down or swings, the anti-vibration roller will drive the strip to move together, and the anti-vibration roller will be frequently adjusted under different specifications of strip and different tension conditions. The blowing distance and angle between the nozzle and the strip have certain range requirements to achieve the best blowing effect. In this case, the existing technology limits the blowing effect and the plate surface quality is unstable; a large number of related parts and equipment are arranged inside and before and after the leveling machine, and the space is relatively narrow. The closer the anti-vibration roller and the anti-wrinkle roller are to the rolling roller, the better the effect, but the roller changing track crossing inside limits the anti-vibration roller and the anti-wrinkle roller from the rolling roller. The limit position of the side, and the retracted position of the front and rear telescopic guide plates limits the anti-wrinkle roller and the anti-trembling roller from approaching and moving away from the limit position of the roll side. Therefore, the anti-trembling roller and the anti-wrinkle roller can only move in a narrow channel, and the diameter of the blowing manifold is relatively large, which is difficult to arrange in a narrow channel; in order to remove the leveling liquid residue carried on the surface of the strip, a compressed air flow of 5000-6000L / min is often configured for plate surface blowing. For production enterprises, the amount of compressed air consumed by the leveling unit in year-round production is very large, and the operating cost of the air compressor station is also high. It is a very meaningful measure to effectively save production costs, reduce the cost per ton of steel for enterprises, and improve the market competitiveness of enterprises.
