The vertical cutting line (also known as the "slitting line") is an automated industrial equipment designed for continuous longitudinal cutting, slitting and winding of metal coils (such as cold-rolled steel coils, hot-rolled steel coils, stainless steel coils, galvanized coils, aluminum coils, etc.). It can accurately divide wide coils into narrow coils or fixed-length plates of preset width, and serves as a core equipment for achieving large-scale and high-precision slitting in the field of metal material deep processing.
