In the rough rolling mill reduction device of the medium and heavy plate rolling mill and the hot strip rolling line, the reduction nut and the reduction screw are very important parts. The reduction system consists of a reduction nut, a reduction screw, a spherical pad and a bearing seat of the upper support roller.

Screw press refers to the general name of pressure machinery that generates pressure by rotating more than one set of outer bolts and inner bolts in the frame. The screw of the electric screw press is a main pressure-bearing device. It has many types of forces, such as torsion, tensile stress, compressive stress, bending moment and various stress combinations, which are very complicated.

The reduction device of the rolling mill is one of the important structures of the rolling mill, used to adjust the roll gap, also called the roll gap adjustment device. The pressing screw is composed of three parts: the contact end with the roll chock is called the head;
