[0002] Steel is a strip steel with a certain cross-sectional shape and size. It is one of the four major types of steel (plate, tube, profile, wire). According to the cross-sectional shape, steel is divided into simple cross-sectional steel and complex cross-sectional steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, curved steel, etc.

[0003] Generally speaking, steel is mainly rolled from billets. The continuous casting billets sent from the steel mill first enter the heating furnace, then go through the primary rolling mill and then the finishing mill after repeated rolling. Steel rolling belongs to metal pressure processing. To put it simply, rolling steel plates is like rolling noodles. After repeated squeezing and pushing by the rolling pin, the noodles become thinner and thinner. On the hot rolling production line, the billets are heated and softened, and then sent into the rolling mill by rollers, and finally rolled into the size required by the user.

[0004] Before the above-mentioned various steels are discharged from the production line, due to reasons such as rolling accuracy or temperature control, the profiles are prone to warping and deformation during the rolling process of the rolling rollers, which has an adverse effect on the feeding at the downstream rolling roller feed port. In addition, when the downstream rolling rollers have warped and deformed profiles at the rolling ends, other parts of the profiles will be lifted due to the leverage effect, which has an adverse effect on the rolling process of the profiles and urgently needs improvement.
