The short stress rolling mill is a profile rolling mill with a short stress loop of the working machine. The stress loop of the working stand refers to the neutral line of the elastic deformation section of the stressed parts in the rolling mill after the rolling force is applied to the rolling mill. The length of the stress loop is the sum of the lengths of the stressed parts in the rolling mill. The elastic deformation produced by each stressed part in the rolling stand is directly proportional to its sectional area and inversely proportional to its length. The shorter the stress loop in the stand, the smaller the elastic deformation produced, the greater the stiffness of the rolling mill (see the stiffness coefficient of the rolling mill), and the higher the accuracy of the rolled products.
