In the screwdown device of the roughing mill of the medium and heavy plate rolling mill and the hot rolled strip rolling line, the screwdown nut and screw are very important components. During the rolling process, every adjustment of the rolling gap is completed by the screwdown nut and screw, and the huge pressing force is also transmitted to the frame through them. If the screwdown nut and screw fail, it will cause the entire rolling line to stop production.
