Strip inspection station and how to use it

Abstract

The invention relates to a strip steel inspection station and a using method thereof. The strip steel inspection station comprises an upper layer of inspection platform and a lower layer of inspectionplatform. The two layers of inspection platforms are linked through a steering device, and the steering device comprises an inner layer of arc-shaped frame and an outer layer of arc-shaped frame. Theouter layer of arc-shaped frame is located on one side, away from the two inspection platforms, of the inner layer of arc-shaped frame. An uncoiling machine is arranged at one end, away from the outer layer of arc-shaped frame, of the lower layer of inspection platform. A plurality of guide rollers are sequentially arranged on the outer surface of the inner layer of arc-shaped frame and the innersurface of the outer layer of arc-shaped frame in the corresponding arc length directions, the axial directions of the multiple guide rollers are parallel to the width direction of strip steel, and the multiple guide rollers form a strip steel operating channel with the opening degree being larger than the thickness of the strip steel in a limiting mode. Through reasonable arrangement of equipment and reasonable structural form selection, the bottom-to-top type double-layer strip steel inspection station is developed, strip face turnover of the strip steel can be smoothly conducted, secondaryscratching is effectively reduced and avoided, and double-face inspection of the strip steel can be achieved.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and further relates to the technical field of steel rolling, in particular to a strip inspection station and a method for using the same. Background technique [0002] The inspection station is located downstream of the continuous rolling line and is used to inspect the surface quality of the strip steel after unwinding the coils produced by the rolling line, or to perform sample testing after shearing with sampling shears. Currently, there are three types of checkpoint arrangements in China: [0003] (1) Platform direct paving single-sided inspection type, the strip steel is unrolled on the platform through the uncoiler, only the surface quality of one side can be inspected, and the other side can only be visually inspected at the uncoiler and cannot be polished; [0004] (2) Double-layer inspection of double-layer platform with direct laying, generally from the upper inspection platform to ...

Problems solved by technology

[0003] (1) Platform direct paving single-sided inspection type, the strip steel is unrolled on the platform through the uncoiler, only the surface quality of one side can be inspected, and the other side can only be visually inspected at the uncoiler and cannot be polished;

[0004] (2) Double-layer inspection of double-layer platform with direct laying, generally from the upper inspection platform to the lower inspection platform through the arc-shaped steering roller turning over inspection, but it cannot be suspended and polished;

[0006] The main problem at the checkpoint is that during the unfolding process, it is easy to cause secondary scratches on the strip, making it impossible to analyze and find out the real reason
