Ultra-high strength strip steel surface cleaning device

Abstract

The invention discloses an ultrahigh-strength strip steel surface cleaning device. The ultrahigh-strength strip steel surface cleaning device mainly comprises a machine body, a squeezing and drying roller assembly, an upper inverted E-shaped frame driving mechanism, an upper squeezing and drying roller box driving mechanism and an air sweeping mechanism. According to the device, frame lifting andpressure adjustment of an squeezing and drying roller are controlled separately, the number of large hydraulic cylinders is reduced from four to two, the hydraulic cylinder used for adjusting the pressure of the squeezing and drying roller can be a small hydraulic cylinder, and follow-up automatic roller changing is possible; and the squeezing-dry pressure adjusting range is widened by adopting the small hydraulic cylinder. The overall device is high in structural rigidity and is suitable for production of high-strength steel. The structure is compact, and the two devices for purging and squeezing are combined into one, so that the requirement for the distance between a roller and a reeling machine is shortened as much as possible by a single-machine reversible rolling mill, and the yieldis improved.

Description

technical field [0001] The invention relates to a cold-rolling reversing rolling mill squeezing device, and more specifically relates to a super-high-strength steel strip surface cleaning device. Background technique [0002] In the cold rolling area of ​​metallurgical enterprises, cold rolling reversing rolling mills are widely used due to their low investment and small footprint. Both the inlet and outlet of the reversing mill are equipped with an emulsion removal system to remove residual oil and iron on the surface of the strip, mainly including a squeeze roller and a compressed air blowing device. [0003] The squeeze roller itself is a part that needs to be replaced periodically, and its structure should be as easy as possible to replace, and the pressure can be adjusted according to the strip steel specification and surface quality during the service cycle. Especially in the current production of ultra-high-strength steel, the squeezing roller device also needs to be...

AI Technical Summary

Problems solved by technology

In addition, the structure of the existing squeeze roller cannot adapt to the production of high-strength steel, especially ultra-high-strength steel. The squeeze roller is directly impacted by the changing load of the strip steel when it is working. The guide liner is under the action of the frame, and the connecting bolts are very easy fracture, the liner is easily deformed, and cannot meet the needs of normal production of high-strength steel units at all
