This standard specifies the structural type, basic parameters, technical conditions, test methods, inspection and packaging of high-precision four-roll strip hydraulic rolling mills. This standard applies to small and medium-sized precision four-high strip cold rolling mills with automatic thickness control (hereinafter referred to as four-high hydraulic rolling mills). Small and medium-sized precision four-roll strip cold rolling mills without automatic thickness control can also be implemented as a reference.
