Side rolling roller and rolling method using the same

Abstract

There is provided a side rolling roller and a rolling method using the same. A side rolling roller according to an aspect of the invention may include: at least one inclined rolling unit performing a rolling process to form an inclined portion on a side of the slab; and at least one curved rolling unit performing a rolling process to form a depressed portion in connection with the inclined portion. Accordingly, the size of a defective region generated in the widthwise ends of a slab can be reduced in a rolling process, the slab can be prevented from being lifted, skewed, and / or separated by the side rolling roller to thereby reduce the size of the defective region generated in the widthwise ends of the slab, and defects occurring at the end of the slab caused by bulging and dog-bone deformation in the rolling process can be reduced.

Description

technical field [0001] The present invention relates to a rolling roller and a rolling method using the same, which reduce defects generated on the edge of a slab during the rolling process. Background technique [0002] Generally, a rolling process including five to seven passes is performed on a slab for obtaining a thickness and a width of the slab corresponding to a reference size of a product. [0003] Such as figure 1 As shown, the rolling system that has been used in the rolling process according to the related art includes: a side roll 2 that performs a rolling process on a slab 20 to reduce its width; and a thickness roll 3 that rolls on the slab A rolling process is performed on the billet 20 to reduce its thickness. The rolling system 10 may further include a finishing roll 4 to smooth the surface of the slab 20 subjected to the rolling process, thereby performing a finish rolling process to obtain a finished thickness. Furthermore, tension reels 5 may be provi...
