Skin-pass mill machine is specially developed and designed for higher- requested hot rolled galvanized sheet, non-ferrous alloy plate etc, improving the sheet surface quality and change the surface finish, eliminates the stress and the yield, to some extent improve the plate type, sometimes applied in low intensity non-ferrous alloy thick plate production line, used to improve the surface and skin finish accordingly.

Skin-pass mill machine is similar to structure of rolled piece, just rolling force and rolling torque is small, according to its structure can be divided into two-roller , four-roller skin-pass machine etc, and according to different working condition, plate skin-pass mil is applied to galvanized sheet , aluminum sheet, magnesium sheet , titanium etc.

Through cooperation with domestic famous university institutes, as Northeastern University, Yanshan University, NHI self-designed and self-developed a number of production line for skin-pass machine, widely used in major and famous steel plant, non-ferrous alloy factory etc. the skin-pall machine of NHI mainly consists of frame, rolls, pressing down and other parts, features in simple structure, full function, and easy maintenance. Specified for cold-rolled galvanized sheet client, we developed high-configuration skill-pass machine with a hydraulic AGC press-down, working roll bending control, rolling line adjustment system, tension adjustment system etc world-class control systems. In the year of 2014, according to market request, we developed a new magnesium alloy sheet skin-pass machine, which can effectively improve the appearance internal quality of magnesium alloy sheet and. Presently, NHI has designed and manufactured several sets of such skin-pass machine, sincerely serve the clients with strong design and production capabilities.
